Technical problem

Here, in the accessory described in patent document 1, when the heat storage layer is directed to the indoor side after storing heat, the indoor side can be heated by the heat from the heat storage layer, but since the rotary body functions only as a simple heat insulating material while the heat storage layer is directed to the outdoor side, the indoor air conditioning effect (temperature adjustment effect, humidity adjustment effect, or component concentration adjustment effect) cannot be obtained.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a swivel fitting capable of providing an air conditioning effect to an indoor side even if any one of surfaces becomes an outdoor side.

Solution to the problem

The rotating fitting according to the present invention includes a flat plate body that can rotate in a state where the first surface faces outdoors and in a state where the second surface faces outdoors. The flat body utilizes at least one of solar energy, atmospheric heat, atmospheric humidity, and a concentration of a specific gas in the atmosphere, such as an oxygen concentration in the atmosphere, a carbon dioxide concentration in the atmosphere, and a Volatile Organic Compound (VOC) concentration in the atmosphere, and provides an air conditioning effect to a room both in a state where the first surface faces outdoors and in a state where the second surface faces outdoors.

Advantageous effects of the invention

According to the present invention, since the air conditioning effect is provided to the room both in the state where the first surface faces the outside and in the state where the second surface faces the outside, when one surface is the outside, the temperature, humidity, and component concentration cannot be automatically adjusted only by exerting the heat insulating effect, and even when any one surface is the outside, the air conditioning effect can be provided to the inside.

Detailed Description

Hereinafter, the present invention will be described with reference to preferred embodiments. The present invention is not limited to the embodiments described below, and may be appropriately modified within a scope not departing from the spirit of the present invention. In the embodiments described below, there may be a portion in which a part of the configuration is not shown and description thereof will be omitted, but with respect to the details of the omitted technique, it goes without saying that a well-known technique or a well-known technique is appropriately applied within a range not causing inconsistency with the following.

Fig. 1 is a sectional view showing a pivot window according to a first embodiment of the present invention. Hereinafter, a pivot window (whether the window is opened or closed) adapted to the window will be described by taking the pivot fitting as an example, and the pivot fitting is not limited to the fitting applied to the pivot window but may be a rotating outer wall material.

The pivot window 1 according to the example shown in fig. 1 includes about two sheets of sheet material 10, a vacuum sealing member 20, a first cell 30, a second cell 40, and two sheets of partition walls 50.

The two sheets 10 are transparent and water vapor permeable sheets, disposed almost parallel to each other. These sheet materials 10 are formed of, for example, moisture-permeable polyurethane resins used for porous glass, silicone, and surgical films, and moisture-permeable waterproof films such as tyvek (registered trademark).

The vacuum seal member 20 is sandwiched between the two plate materials 10 at the outer peripheral end portions of the two plate materials 10. The vacuum sealing member 20 is provided at peripheral end portions of the two sheet materials 10, thereby forming an inner space enclosed by the two sheet materials 10 and the vacuum sealing member 20.

The first unit 30 and the second unit 40 are disposed in an inner space formed by two sheets of the plate material 10 and the vacuum sealing member 20. The first cell 30 and the second cell 40 are hermetically separated by two sheets of partition walls 50. The two sheets of partition walls 50 are formed of a transparent plate material, and are separated from each other so that one side of a first sheet (a first surface and one sheet) 10a of the two sheets of sheets 10 is defined as a first cell 30, and one side of a second sheet (a second surface and the other sheet) 10b of the two sheets of sheets 10 is defined as a second cell 40. A vacuum insulation layer (insulation layer) VIL is formed between the two sheets of insulation walls 50.

More specifically, the two sheets of the partition wall 50 each have a zigzag shape in cross section, and a plurality of first inner spaces IS1 are formed by the first wall 51 of the two sheets of the partition wall 50 and the first sheet material 10 a. Each of the plurality of first inner spaces IS1 has a triangular shape in sectional view. The first inner space IS1 IS filled with hygroscopic liquid Li. As a result, the hygroscopic liquid Li and the first wall 51 form the first triangular prism 31. The first unit 30 is formed of a plurality of first triangular prisms 31 and a plurality of first selective absorbing parts (first solar receiving parts) 32, which will be described later. In the following description, an example in which the first internal space IS1 IS filled with the hygroscopic liquid Li will be described, but the present invention IS not limited to the liquid Li, and the first triangular prism 31 may be formed by encapsulating the hygroscopic solid and gel-like body in the first internal space IS 1.

Likewise, a plurality of second inner spaces IS2 are formed by the second wall 52 of the two partition walls 50 and the second sheet material 10 b. Each of the plurality of second inner spaces IS2 has a triangular shape in sectional view. The second inner space IS2 IS filled with hygroscopic liquid Li. As a result, the hygroscopic liquid Li and the second wall 52 form the second triangular prism 41. The second unit 40 is formed of a plurality of second triangular prisms 41 and a plurality of second selective absorbing portions (second solar receiving portions) 42 which will be described later. In the following description, an example in which the second internal space IS2 IS filled with the hygroscopic liquid Li will also be described, but the present invention IS not limited to the liquid Li, and the second triangular prism 41 may be formed by encapsulating the hygroscopic solid and gel-like body in the second internal space IS 2.

Fig. 2 is an enlarged sectional view including the first triangular prism 31. The first triangular prism 31 is formed by a first side 31a, a second side 31b and a third side 31c which are angled with respect to the first side 31a along the two sheet materials 10 in a cross-sectional view. The second side 31b is a side located vertically below the third side 31c in the pivot window 1 in the erected state.

The first selective absorption part 32 is installed on the second side 31b, and absorbs solar energy from sunlight incident through the first triangular prism 31. The first selective absorption part 32 is arranged in the wavelength range of the sunlightHas high absorptivity and is in the wavelength range of infrared rayIs formed in such a manner that the emissivity is reduced. In the example shown in fig. 2, the first selective absorbing portion 32 IS accommodated in the first internal space IS1, but the present invention IS not limited thereto. The first selective absorbing portion 32 may be disposed outside the first inner space IS1 (outside the first wall 51).

Here, in the first triangular prism 31, the refractive index and each internal angle of the triangle are set, thereby realizing the following three types of optical paths OP1 to OP 3. In the first optical path OP1 of the three types of optical paths OP1 to OP3, sunlight passing through the first plate material 10a and entering the first triangular prism 31 from the first edge 31a directly reaches the second edge 31 b. In the second optical path OP2, the sunlight is totally reflected by the third side 31c and reaches the second side 31 b. In the third optical path OP3, the sunlight reaches the second side 31b after being totally reflected in the order of the third side 31c and the first side 31 a.

In order to realize the above-described first to third optical paths OP1 to OP3, it is required that the incident angle of the second optical path OP2 with respect to the third side 31c is equal to or larger than the critical angle. The incident angle of the third optical path OP3 with respect to the third side 31c is equal to or greater than the critical angle, and the incident angle with respect to the first side 31a after total reflection is also equal to or greater than the critical angle.

In this way, since the first triangular prism 31 is configured to realize three types of optical paths OP1 to OP3, the first selective absorbing part 32 can efficiently receive solar energy, and thus the first triangular prism 31 can be heated. The heated triangular prism 31 discharges moisture from the hygroscopic liquid Li.

In the first embodiment, it is assumed that the hygroscopic liquid Li and the first wall 51 are both configured to have the same refractive index (for example, refractive index 1.41), but the present invention is not particularly limited thereto. The first triangular prism 31 is formed of the hygroscopic liquid Li and the first wall 51, but is not limited thereto. The first triangular prism 31 may include a triangular tube capable of enclosing the liquid Li inside, and the hygroscopic liquid Li may be enclosed in the triangular tube. The first triangular prism 31 may be formed of a solid substance such as porous glass.

Reference is again made to fig. 1. The second triangular prism 41 is formed by a fifth side 41b and a sixth side 41c that are angled with respect to the fourth side 41a along the fourth side 41a of the two sheet materials 10 in the cross-sectional view. The fifth side 41b is a side located vertically above the sixth side 41c in the pivot window 1 in the erected state.

The second unit 40 having the second triangular prism 41 and the second selective absorbing portion 42 as described above has a structure point-symmetrical to the first unit 30 about the center position CP of the height and thickness of the pivot window 1 in the sectional view. Therefore, as described later, when the pivot window 1 is vertically rotated (half-rotated in the vertical direction) while maintaining its left-right position, the second triangular prism 41 realizes three types of optical paths OP1 to OP 3. Since the first and second triangular prisms 31 and 41 have the same shape and form a pair, an image restoration effect can be provided. That is, when the user visually recognizes the landscape from the indoor side, the distortion of the landscape is configured to be suppressed. The second triangular prism 41 is also formed by the hygroscopic liquid Li and the second wall 52 in the same manner as the first triangular prism 31, but is not limited thereto. The second triangular prism 41 may include a triangular tube capable of enclosing the liquid Li inside, and the hygroscopic liquid Li may be enclosed in the triangular tube. The second triangular prism 41 may be formed of a solid substance such as porous glass.

The second selective absorbing part 42 is installed on the fifth side 41b, and when the pivot window 1 is half-rotated in the vertical direction, the second selective absorbing part 42 receives solar energy from the solar light incident through the second triangular prism 41. Like the first selective absorption part 32, the second selective absorption part 42 is formed to be in the wavelength range of sunlightHigh internal absorption and in the infrared wavelength rangeThe internal emissivity is reduced. In the example shown in fig. 1, the second selective absorbing portion 42 IS accommodated in the second inner space IS2, but the present invention IS not limited thereto. The second selective absorbing portion 42 may be disposed outside the second inner space IS2 (outside the second wall 52).

Here, the second triangular prism 41 is on the indoor side in the state shown in fig. 1. Since the second plate material 10b is water vapor-permeable, the second triangular prism 41 can absorb moisture on the indoor side, and thus can provide a humidity control effect for the indoor space.

Fig. 3 is a perspective view showing the pivot window 1 according to the first embodiment, and shows a rotating mechanism. In the following description, the configuration of the pivot window 1 (two sheets of plate materials 10, the vacuum seal member 20, the first unit 30, the second unit 40, and the partition wall 50) excluding the rotation mechanism 60 is referred to as a laminated body (flat body) L.

As shown in fig. 3, the pivot window 1 has transparent louvers TL1, also referred to as louvers, on the outdoor side of the laminated body L. The pivot window 1 has an indoor louver TL2 on the indoor side of the laminated body L. The pivot window 1 according to the first embodiment includes a rotating mechanism 60. The rotating mechanism 60 includes a pivot 61, a window frame 62, and a lock portion, not shown, and the stacked body L may be half-rotated without contacting the louvers TL1 and TL 2.

More specifically, the pivot shaft 61 is a rotary shaft member provided at any one of the upper end portion and the lower end portion LT2 of the laminated body L. The above-mentioned pivots 61 are provided on the left and right sides of the laminated body L, respectively. The laminated body L is fitted to the window frame 62, and the laminated body L fitted to the window frame 62 is in a locked state in which the fitted state is maintained by a locking unit, not shown. The pivot shaft 61 is slidable with respect to the left and right members 62a of the window frame 62. The indoor louver TL2 can be opened and closed in the indoor direction.

According to the above configuration, the rotating operation can be performed as follows. First, it is assumed that the pivot 61 is located at the lower end of the window frame 62. From this state, the indoor louver TL2 is opened. Next, the locking unit is released, and the end LT1 of the side of the laminated body L where the pivot shaft 61 is not provided is pulled toward the indoor side. Next, the end LT2 on the pivot shaft 61 side of the laminated body L is slid upward with respect to the window frame 62. Thereafter, when the end LT2 of the laminated body L reaches the upper end of the window frame 62, the laminated body L is fitted to the window frame and locked by the locking unit. Finally, the indoor louver TL2 is closed.

As described above, the half rotation operation in the vertical direction is performed. When the half rotation operation in the vertical direction is performed, the vertical position is reversed while the horizontal positions of the first unit 30 and the second unit 40 are maintained.

Next, the action of the pivot window 1 according to the first embodiment will be described. First, it is assumed that the first unit 30 shown in fig. 1 faces the outdoor side and the second unit 40 faces the indoor side.

In this state, sunlight reaches the first cells 30 via the first plate material 10 a. Since the first triangular prism 31 of the first unit 30 implements three types of the optical paths OP1 to OP3, the first selective absorbing part 32 efficiently receives sunlight and receives solar energy. The hygroscopic liquid Li forming the first triangular prism 31 is heated by the first selective absorbing portion 32, thereby discharging moisture. Moisture released from the hygroscopic liquid Li is discharged to the outside air through the water vapor permeable first sheet 10 a.

On the other hand, in the second unit 40, the hygroscopic liquid Li forming the second triangular prism 41 absorbs moisture on the indoor side. That is, moisture on the indoor side is absorbed into the hygroscopic liquid Li through the second plate material 10b having water vapor permeability. Therefore, the humidity control effect is exhibited indoors.

Assume that the stacked body L is half-rotated in the vertical direction while maintaining the left-right position by using the rotating mechanism 60 shown in fig. 3. In this case, the second unit 40 faces the outdoor side, and the first unit 30 faces the indoor side.

In this state, sunlight reaches the second cell 40 via the second plate material 10 b. Since the second cell 40 and the first cell 30 have a point-symmetric structure, three types of optical paths OP1 to OP3 are also realized in the second triangular prism 41 of the second cell 40. Therefore, the second selective absorption part 42 efficiently receives the solar light and receives the solar energy. The hygroscopic liquid Li forming the second triangular prism 41 is heated by the second selective absorbing portion 42, thereby discharging moisture. That is, moisture is discharged from the hygroscopic liquid Li that absorbs moisture inside the chamber, thereby regenerating the hygroscopic liquid Li.

On the other hand, in the first cell 30 which is the indoor side, the hygroscopic liquid Li forming the first triangular prism 31 is in a regenerated state, and therefore, the moisture in the indoor side is absorbed. Therefore, the humidity control effect is exhibited indoors.

In this way, according to the pivot window 1 of the first embodiment, since the humidity control effect is exhibited in both the state where the first plate member 10a faces the outside and the state where the second plate member 10b faces the outside, it is possible to provide the humidity control effect to the inside of the room without causing the automatic temperature and humidity control to be impossible only by exhibiting the heat insulating effect when one surface is the outside of the room, and even if any one surface is the outside of the room.

Since the rotation in the vertical direction can be performed while maintaining the left-right position, for example, when the relative positions of the first plate material 10a and the second plate material 10b are switched and the vertical rotation is not performed, by performing the rotation appropriately, when the humidity control effect cannot be obtained on both surfaces, the humidity control effect can be provided to the indoor space.

As the first unit 30, a first triangular prism 31 and a first selective absorption section 32 having absorptance are provided, and as the second unit 40, a second triangular prism 41 and a second selective absorption section 42 having absorptance are provided. Therefore, when the first unit 30 is outside the room, the first unit 30 outside the room is heated by solar energy, and moisture is discharged from the first triangular prism 31 and regenerated, so that the second unit 40 outside the room absorbs moisture inside the room, thereby providing a humidity control effect. When moisture is sufficiently absorbed by the second triangular prism 41 of the second unit 40, the second unit 40 becomes the outdoor side by performing vertical rotation, and the second triangular prism 41 of the second unit 40 side can be regenerated. The first unit 30 moves to the indoor side in a state of being regenerated by the vertical rotation, and absorbs the humidity of the indoor side, so that a humidity control effect can be provided. Thus, a continuous humidity reduction effect can be obtained.

Since the first unit 30 and the second unit 40 each include the triangular prisms 31 and 41, and the second side 31b and the fifth side 41b are disposed to face each other, the triangular prisms 31 and 41 become a pair, thereby making it possible to serve as a window for suppressing distortion when the user visually recognizes a landscape.

In the above, a method called a temperature change method of absorbing and desorbing moisture in air by utilizing the fact that the amount of water absorbed by the hygroscopic material changes according to the temperature thereof is described. In the same manner, when the absorbent of oxygen, carbon dioxide and Volatile Organic Compounds (VOC) is used instead of the hygroscopic material, the concentrations of oxygen and carbon dioxide and the concentration of Volatile Organic Compounds (VOC) in the room can be adjusted by the temperature change method.

Next, a second embodiment of the present invention will be described. The pivot window according to the second embodiment has the following configuration. Hereinafter, in the description of the second embodiment, the same or similar elements as those of the first embodiment will be denoted by the same reference numerals.

Fig. 4 is a sectional view showing a pivot window according to a second embodiment. As shown in fig. 4, the pivot window 2 according to the second embodiment roughly includes two sheets of plate material 10, a vacuum seal member 20, a slope 70, and a hydraulic fluid (liquid) HF.

The two sheets 10 are transparent sheets arranged almost parallel to each other. These plates 10 are formed of, for example, a glass material. These sheet materials 10 do not have moisture permeability, unlike the first embodiment. In the second embodiment, from the viewpoint of heat insulation, the internal space formed by the two sheets of sheet materials 10 and the vacuum sealing member 20 is in a vacuum state. The internal space is not limited to a vacuum state, but may be filled with a predetermined gas.

The slope 70 is a transparent member interposed between two sheets of the plate material 10, and is folded twice at 90 degrees in the sectional view state shown in fig. 4 to form a curved body having an approximately N-shaped cross section. In the slope 70, one end portion 70a is provided in contact with the inner wall of the first plate material 10a, and the other end portion 70b is provided in contact with the inner wall of the second plate material 10 b. The inclined surface 70 forms a reservoir Res capable of storing the hydraulic fluid HF together with the first plate member 10a at one end side.

Fig. 5 is a perspective view showing details of the ramp 70 shown in fig. 4. As shown in fig. 5, the inclined surface 70 includes a lower plate 71, an upper plate 72 disposed in parallel with the lower plate 71, and a connecting plate 73 connecting the lower plate 71 and the upper plate 72.

The lower plate 71 has the above-described end portion 70a, and the opposite side of the end portion 70a is formed into a comb-tooth portion 71a protruding in a comb-tooth shape. Each end face EF of the comb-teeth portion 71a is a portion that contacts the inner wall of the second plate material 10 b. The upper plate 72 has a point-symmetrical structure with the lower plate 71 via the connecting plate 73. That is, the upper plate 72 is formed as a comb-tooth portion 72a protruding in a comb-tooth shape on the side opposite to the end portion 70 b. Each end face EF of the comb-teeth portion 72a is a portion that contacts the inner wall of the first plate material 10 a. In this way, the opposite end portions (the end portion 70a and the end face EF) of the lower plate 71 and the opposite end portions (the end portion 70b and the end face EF) of the upper plate 72 of the inclined surface 70 contact the two sheets of sheet material 10, respectively. Thus, the inclined surface 70 supports the two sheets of the plate material 10 in a vacuum state from the inside thereof.

Reference is again made to fig. 4. In this embodiment, the hydraulic fluid HF is a transparent liquid such as water. The hydraulic fluid HF is not limited to water. The hydraulic fluid HF is stored in the storage section Res. The hydraulic fluid HF in the reservoir Res may be evaporated by heat from the first plate 10 a. The vaporized hydraulic fluid HF becomes water vapor and reaches the second plate material 10 b. The hydraulic fluid HF, which becomes water vapor, condenses and liquefies in the second plate 10 b. The liquefied hydraulic fluid HF flows down the inner surface of the second sheet material 10b and accumulates on the upper plate 72 of the ramp 70 (see fig. 5). When a certain amount or more of the hydraulic fluid HF is accumulated on the upper plate 72, the hydraulic fluid HF falls into the reservoir Res from the gap between the comb teeth portions 72a of the upper plate 72.

Specifically, when the room temperature is 20 ℃ and the outside air temperature is 25 ℃, the vapor pressure of water (hydraulic fluid HF) stored in the storage part Res is about 2.4kPa, and the internal space serves as an insulating glass having a degree of vacuum of about 2.5/100 atm. When the room temperature is raised from this state to 30 c, the water continues to evaporate, and the pressure of the internal space is raised to 4.3kPa, but the evaporated water (water vapor) is cooled and liquefied when it comes into contact with the second sheet material 10b on the outdoor side, and flows down on the inner surface of the second sheet material 10 b. The water flowing downward returns to the reservoir Res via the upper plate 72 of the ramp 70.

As described above, the hydraulic fluid HF is returned from the reservoir Res to the reservoir Res again via the second plate member 10b, and the slope 70 has a liquid circulation structure capable of circulating the hydraulic fluid HF. The first sheet 10a functions as an evaporator because the hydraulic fluid HF evaporates, and the second sheet 10b functions as a condenser because the hydraulic fluid HF condenses. Therefore, the side of the first plate material 10a is cooled by removing the evaporation heat, and the condensation heat is radiated from the side of the second plate material 10 b. As a result, the heat of the first plate material 10a side flows to the second plate material 10b side, for example, in summer, the indoor side becomes the first plate material 10a, so that the temperature control effect can be obtained, making the room comfortable without absorbing moisture. In summer when the room temperature is low, the hydraulic liquid HF can be used as insulating glass without evaporation.

Here, although the slope 70 forms the bank Res together with the first plate material 10a in the present embodiment, a heat transfer member may be attached to the inner surface of the first plate material 10a to form the bank Res together with the heat transfer member. That is, the slope 70 may form a bank Res on one side of the first plate material 10a together with other members. In this embodiment, the hydraulic fluid HF reaches the second plate material 10b and is condensed and liquefied, but the present invention is not limited thereto, and the heat transfer member may be mounted to the inner surface of the second plate material 10 b. Thus, the hydraulic fluid HF may reach the heat transfer member and may be condensed and liquefied.

When the slope 70 has a liquid circulation structure that circulates the hydraulic fluid HF, the structure is not limited to the structure shown in fig. 5, and may be, for example, a simple inclined structure (an inclined structure that is inclined from the end 70a to the end 70 b).

The first plate material 10a may be heat absorbing glass (glass containing metal such as iron in glass composition) for improving evaporation capacity. In order to improve the heat insulation property at the time of heat insulation, the inner surface of at least one of the two sheet materials 10 may be subjected to infrared reflection treatment.

Fig. 6 is a perspective view showing the pivot window 2 according to the second embodiment, and shows a rotating mechanism. As shown in fig. 6, the pivot window 2 includes a rotating mechanism 60 in addition to the structure shown in fig. 4. The rotating mechanism 60 includes a pivot 61, a window frame 62, and a not-shown locking unit in the same manner as the first embodiment.

The pivot 61 is connected to the center of the upper and lower sides of a stacked body (flat body) L including two sheets of the plate material 10, the vacuum sealing member 20, and the inclined surface 70. The pivots 61 are rotatably provided at the central portions of the upper and lower members 62b of the rectangular sash 62, respectively. Therefore, the stacked body L is rotatable centering on the pivot 61, and the vertical position of the stacked body L is maintained while rotating while half-rotating in the horizontal direction, whereby the relative positions of the first plate material 10a and the second plate material 10b can be switched.

After performing the half rotation, the laminated body L is locked to the window frame 62 by the locking unit. Thus, a pivot window 2 with opposite heat flow directions can be obtained. That is, by half-rotating the stacked body L, the cooling effect and the heating effect in the room can be switched.

The configuration of half-rotating the stacked body L is not limited to the configuration shown in fig. 6. Fig. 7 is a perspective view showing another example of the pivot window 2 according to the second embodiment. As shown in fig. 7, the pivot window 2 further includes a fixed glass FG on the outdoor side. Therefore, the pivot window 2 shown in fig. 7 is configured to be able to perform half rotation without bringing the laminated body L into contact with the fixed glass FG.

In the example shown in fig. 7, the pivot shaft 61 is provided at the left or right end LW1 of the laminated body L, and the pivot shaft 61 is slidable with respect to the upper and lower members 62b of the window frame 62. The rotation operation can be performed as follows. First, it is assumed that the end LW1 of the laminated body L on the pivot 61 side is located on one of the left and right members 62a of the window frame 62. When the laminated body L is half-rotated from this state, the locking unit is first released. Next, the end LW2 of the laminate L on the side where the pivot 61 is not provided is drawn out to the indoor side. Next, the end LW1 on the pivot shaft 61 side of the laminated body L is slid to the other side of the left and right members 62a of the sash 62. After that, the laminated body L is fitted to the window frame 62 so that the end portions LW2 of the laminated body L become one side of the left and right members 62a, and locked by the locking unit.

As described above, even in the case where the pivot window 2 includes the fixed glass FG on the outdoor side, the heat flow direction can be reversed, and the cooling and heating in the room can be switched.

Next, the operation of the pivot window 2 according to the embodiment will be described. First, as shown in fig. 4, it is assumed that the first plate material 10a becomes the indoor side and the second plate material 10b becomes the outdoor side. In this case, when the room temperature is 20 ℃ and the outside air temperature is 25 ℃, the hydraulic fluid HF in the reservoir Res does not evaporate. Meanwhile, since the inner spaces of the two sheets 10 are in a vacuum state, a heat insulating effect is achieved, and the pivot window 2 serves as heat insulating glass.

On the other hand, for example, when the room temperature is 30 ℃ and the outside air temperature is 25 ℃, the hydraulic fluid HF in the storage part Res evaporates. The vaporized hydraulic fluid HF reaches the second plate 10b outside the chamber, is cooled and liquefied, and flows down along the inner surface of the second plate 10 b. The downward flow of hydraulic fluid HF is again returned to the reservoir Res through the upper plate 72 of the ramp 70. In this process, the first plate material 10a is cooled by the vaporization heat due to the vaporization of the hydraulic fluid HF, and the condensation heat of the hydraulic fluid HF is discharged from the second plate material 10 b. Therefore, heat inside the room is caused to flow to the outside of the room, so that a temperature control effect of cooling the room can be obtained.

As shown in fig. 6 or 7, when the relative positions of the first sheet material 10a and the second sheet material 10b are switched while maintaining their vertical positions, the operation is reversed from the above-described operation.

That is, when the outside air temperature becomes equal to or higher than the predetermined temperature in winter, the hydraulic fluid HF in the storage part Res evaporates. Therefore, in the same manner as described above, the first plate material 10a that becomes the outdoor side is cooled by the evaporation heat generated due to the evaporation of the hydraulic fluid HF, and the condensation heat of the hydraulic fluid HF is discharged from the second plate material 10b that becomes the indoor side. Therefore, heat outside the room is made to flow through the room, so that a temperature control effect of heating the room can be obtained.

The pivot window 2 functions as an insulating glass in the same manner as described above in an environment where the hydraulic fluid HF in the reservoir Res does not evaporate in winter.

As described above, according to the pivot window 2 of the second embodiment, in the same manner as the first embodiment, even if any one surface becomes the outdoor side, it is possible to provide the temperature control effect to the indoor side.

The temperature control effect to be provided is configured to be different according to which one of the first sheet material 10a and the second sheet material 10b becomes the outdoor side. Therefore, the surface to be the outdoor side is selected according to the environment, so that the temperature adjusting effect (air conditioning effect) according to the environment can be obtained.

Since the heat insulating effect can be obtained in the case where the temperature condition for evaporating the hydraulic fluid HF is not satisfied, the heat insulating effect can be obtained in the case where the air conditioning effect cannot be obtained.

For example, since it is possible to rotate in the horizontal direction while maintaining the vertical position, when it is desired to rotate while maintaining the vertical direction, it is possible to provide an air conditioning effect to the indoor side by appropriately rotating.

A slope 70 having a liquid circulation structure is provided in which the hydraulic fluid HF in the reservoir Res where the heat on the first plate 10a side evaporates reaches the second plate 10b side, and the condensate on the second plate 10b side is returned to the reservoir Res again. Therefore, in an environment where the liquid is evaporated by the heat from the first plate material 10a side, the side of the first plate material 10a is cooled by being deprived of the evaporation heat. On the other hand, when the vaporized hydraulic fluid HF reaches the second plate material 10b side, the vaporized hydraulic fluid HF is cooled to be condensed and liquefied, and the condensation heat is discharged from the second plate material 10b side. Therefore, as a result, the heat on the first plate material 10a side flows to the second plate material 10b side, and the cooling effect and the heating effect can be provided to the indoor side by selecting the surface facing the indoor side.

Next, a third embodiment of the present invention will be described. The pivot window according to the third embodiment has the following configuration. Hereinafter, in the description of the third embodiment, the same or similar elements as those of the second embodiment will be denoted by the same reference numerals.

Fig. 8 is a sectional view showing a pivot window according to a third embodiment. As shown in fig. 8, the pivot window 3 according to the third embodiment includes two laminated bodies L (one example of a plurality) according to the second embodiment. The two laminated bodies L are arranged to be opposed with a space therebetween.

In the third embodiment, the sealing member 80 is provided between the two laminated bodies L, and the transparent latent heat storage material 90 is provided in the space sandwiched between the two laminated bodies L and the sealing member 80. The latent heat storage material 90 is made of, for example, inorganic salt hydrate (Na)₂SO₄10H₂O and CaCl₂6H₂O) is formed. The latent heat storage material 90 described above is enclosed and held in a cavity portion of a trapezoidal section material (a plate material in which the cavity portions as the units S are arranged in the vertical direction). The latent heat storage material 90 may be enclosed in a cavity portion of a honeycomb-section material (a plate material in which cavity portions as the cells S are vertically and horizontally arranged in a honeycomb shape). In this embodiment, for example, the melting point and freezing point of the latent heat storage material 90 are at 21 ℃.

The latent heat storage material 90 is not limited to the inorganic salt hydrate, but may be other materials. The melting point and freezing point of the latent heat storage material 90 are not limited to 21 ℃, and may be other temperatures. The latent heat storage material 90 may use materials having different melting points and freezing points. That is, the latent heat storage material 90 may be any material as long as the material has a melting point and a freezing point within a specific temperature range according to the environment in which the pivot window 3 is used. In the present embodiment, the first plate material 10a of one laminated body L1 and the second plate material 10b of the other laminated body L2 are disposed facing each other.

In the above-described pivot window 3, the hydraulic fluid HF is evaporated at a temperature of, for example, 21 ℃ or more in the first plate 10a of the other laminated body L, and the condensation heat is discharged from the second plate 10b side. This heat is accumulated by the latent heat storage material 90. When the temperature of the side of the second plate material 10b of one laminated body L1 is lower than 21 ℃, the hydraulic fluid HF is evaporated in the storage section Res on the side of one laminated body L1 by the heat accumulated in the latent heat storage material 90, and the condensation heat is discharged from the side of the second plate material 10 b. As a result, the heat of the other laminate L2 side flows to the one laminate L1 side via the latent heat storage material 90 as a buffer. Therefore, for example, in summer, the other laminate L2 is provided on the indoor side, and a temperature control effect of cooling a room can be obtained without absorbing moisture.

In particular, the pivot window 3 according to the third embodiment can obtain a cooling effect by using the latent heat storage material 90 even when the outside air temperature is high, for example, the room temperature is 21 ℃ or more. That is, since the latent heat storage material 90 is fixed at 21 ℃, in the case where the room temperature is 21 ℃ or more, heat in the room can be transferred to the latent heat storage material 90, and a cooling effect in the room can be obtained. For example, when the outside air temperature at night becomes 21 ℃ or less, the heat stored in the latent heat storage material 90 is discharged. Therefore, the pivot window 3 is provided with the latent heat storage material 90 as a buffer, so that the frequency of achieving indoor comfort can be increased.

As shown in fig. 6 and 7, the pivot window 3 according to the third embodiment includes the rotating mechanism 60, and is capable of performing a rotating operation in the horizontal direction while maintaining the vertical position, and is capable of switching the relative positions of one laminated body L1 and the other laminated body L2.

The pivot window 3 according to the third embodiment desirably includes a rotating mechanism shown in fig. 9. Fig. 9 is a perspective view showing the pivot window 3 according to the third embodiment, and shows a rotating mechanism. In the example shown in fig. 9, the configuration of the pivot window 3 (two laminated bodies L, the sealing member 80, and the latent heat storage material 90) excluding the rotation mechanism 60 is referred to as a composite laminated body (plate-like body) CL.

As shown in fig. 9, the pivot window 3 according to the third embodiment further includes a fixed glass FG on the outdoor side. Therefore, the pivot window 3 shown in fig. 9 is configured to be capable of half-rotation in the vertical direction and the horizontal direction without bringing the composite laminated body CL into contact with the fixed glass FG.

In the example shown in fig. 9, the rotation mechanism 60 includes a first pivot 63a, a second pivot 63b, a first sash 64a, a second sash 64b, and first and second locking units, not shown.

The first sash 64a is a rectangular frame fixed to the building side. The second sash 64b includes a first pivot shaft 63a provided at either one of the left and right end portions LW1, and the first pivot shaft 63a is slidable with respect to the upper and lower members 62b of the first sash 64 a. The second pivot shaft 63b is mounted at a middle portion in the height direction of the composite laminate CL, and is rotatably provided at a central portion of the left and right members 62a2 of the rectangular second sash 64 b.

Therefore, the rotating operation can be performed as follows. First, it is assumed that the end LW1 on the first pivot shaft 63a side of the second sash 64b is located on one of the left and right members 62a1 of the first sash 64 a. The first locking unit is released from this state, and the end LT2 of the second sash 64b on the side where the first pivot shaft 63a is not provided is pulled toward the indoor side. Next, the second locking unit is released, and the composite laminated body CL is half-rotated in the vertical direction centering on the second pivot shaft 63 b. Next, the composite laminated body CL is locked by the second locking unit. Next, the end LW1 on the first pivot shaft 63a side of the second sash 64b is slid to the other side of the left and right members 62a1 of the first sash 64 a. Thereafter, the second sash 64b is fitted into the first sash 64a such that the end LT2 of the second sash 64b becomes one side of the left and right members 62a and is locked by the first locking unit.

As described above, in the pivot window 3 having the fixed glass FG on the outdoor side, the composite laminated body CL can be rotated in the vertical and horizontal directions.

As shown in fig. 5, in the slope 70, since the lower plate 71 and the upper plate 72 have a point-symmetrical structure in shape with the connecting plate 73 interposed therebetween, the slope 70 forms the reservoir Res even if the composite laminated body CL is half-rotated in the vertical direction. That is, when the composite laminated body CL is half-rotated in the vertical direction, the reservoir Res is formed by the upper plate 72 and the second plate material 10 b.

Here, the latent heat storage material 90 is likely to generate precipitates by repeating solidification and melting, and therefore, the stored heat amount is reduced. However, as shown in fig. 9, since the pivot window 3 according to the third embodiment includes the rotating mechanism 60 that can rotate not only in the horizontal direction but also in the vertical direction, the precipitate can be pulverized during half rotation in the vertical direction, so that the stored heat amount can be recovered. From the viewpoint of pulverizing the precipitate, one or more rotations may be performed in the vertical direction.

Next, the operation of the pivot window 3 according to the third embodiment will be described. First, as shown in fig. 8, it is assumed that the first plate member 10a of the other laminate L2 becomes the indoor side and the second plate member 10b of the one laminate L1 becomes the outdoor side.

In this case, for example, when the room temperature is equal to or higher than 21 ℃, the hydraulic fluid HF in the reservoir Res evaporates. The vaporized hydraulic fluid HF reaches the second plate material 10b outside the chamber to be liquefied and flows down along the inner surface of the second plate material 10 b. The downward flow of hydraulic fluid HF is again returned to the reservoir Res through the upper plate 72 of the ramp 70. In this process, the first plate material 10a is cooled by the vaporization heat generated by the vaporization of the hydraulic fluid HF, and the condensation heat of the hydraulic fluid HF is discharged from the second plate material 10 b. The discharged heat is stored by the latent heat storage material 90. Accordingly, heat at the indoor side can be transferred to the latent heat storage material 90, so that an air conditioning effect of cooling a room can be provided.

With the first laminate L1, when the outside air temperature is equal to or lower than 21 ℃, the hydraulic fluid HF repeats evaporation and condensation in the same manner as described above, so that the heat stored in the latent heat storage material 90 is discharged to the outside air.

When rotation is performed in the horizontal direction using the rotation mechanism 60 as shown in fig. 9, an air conditioning effect of heating a room in winter can be obtained by reversing the above-described operation. When the rotation is performed in the vertical direction using the rotation mechanism 60, an effect of crushing the precipitate of the latent heat storage material 90 is obtained, thereby recovering the stored heat amount. When the rotation is performed in the vertical direction and the horizontal direction, an air conditioning effect in which the operation is reversed while the precipitate is pulverized can be obtained.

As described above, according to the pivot window 3 of the third embodiment, in the same manner as the first embodiment, even if any one surface becomes the outdoor side, it is possible to provide the temperature control effect to the indoor side.

The temperature control effects provided are configured to be different depending on which of the first laminated body L1 and the second laminated body L2 becomes the outdoor side. Therefore, the surface to be the outdoor side is selected according to the environment, so that the temperature adjusting effect (air conditioning effect) according to the environment can be obtained.

Since the heat insulating effect is obtained when the temperature condition for evaporating the hydraulic fluid HF is not satisfied, the heat insulating effect can be obtained even when the air conditioning effect cannot be obtained.

For example, since rotation can be performed in the vertical direction and the horizontal direction, the top and the bottom can be reversed while maintaining the same surface directivity as before the rotation, and vertical inversion can be performed while the same surface is directed outdoors.

Since the latent heat storage material 90 having the melting point and the freezing point within the specific temperature range is provided in the space between the first and second laminated bodies L1 and L2, for example, even when the outside air temperature is higher than the indoor temperature, when the room temperature is equal to or higher than the specific temperature range, the heat in the room is transferred to the latent heat storage material 90, and the heat of the latent heat storage material 90 can be discharged to the outside air when the outside temperature is lower than the specific temperature range at night. In this way, the latent heat storage material 90 is provided as a buffer, thereby making it possible to increase the frequency of achieving indoor comfort. In particular, when rotation is performed in the horizontal direction while maintaining the vertical position, the relative positions of the stacked bodies L1, L2 can be switched in a case where it is desired to change the heat flow direction, such as in summer, winter, daytime, and night, so that cooling and heating can be selected. When rotation is performed in the vertical direction while maintaining the left-right position thereof, the latent heat storage material 90 is vertically rotated, thereby making it possible to suppress deterioration of the heat storage effect due to precipitation of a specific component. When the two rotations are performed, it is possible to suppress deterioration of the heat storage effect due to precipitation of the specific component while changing the cooling and heating.

Next, a fourth embodiment of the present invention will be described. The pivot window according to the fourth embodiment has the following configuration. Hereinafter, in the description of the fourth embodiment, the same or similar elements as those of the first embodiment will be denoted by the same reference numerals.

Fig. 10 is a sectional view showing a pivot window according to a fourth embodiment. As shown in fig. 10, the pivot window 4 according to the fourth embodiment includes two sheets of plate material 10, a vacuum sealing member 20, a solar energy receiving part 100, a plurality of insertion members 110, a refrigerant distributor 120, an absorption liquid distributor 130, and a pump P.

The two sheets 10 are transparent sheets arranged almost parallel to each other. These plates 10 are formed of, for example, a glass material. These sheet materials 10 do not have moisture permeability, unlike the first embodiment. The vacuum sealing member 20 is provided at the outer peripheral end portions of the two sheet materials 10.

The solar energy receiver 100 is an energy collecting panel provided outside the outdoor of the two sheet materials 10 and substantially parallel to the sheet materials 10. The solar receiving part 100 is also formed of a transparent plate material.

The plurality of insert members 110 are disposed in an inner space formed by two sheets of the plate material 10 and the vacuum sealing member 20, and include a first insert member 111, a second insert member 112, and a plurality of third insert members 113.

The first insertion member 111 is disposed on the upper side between the two sheets of the plate material 10. In the fourth embodiment, the space between the vacuum sealing member 20 and the first interposition member 111 sandwiched above is configured to function as a regenerator R for heating a dilute solution of a mixed absorption liquid (e.g., an aqueous lithium bromide solution) and a refrigerant (e.g., water) by the heat received by the solar energy receiving portion 100. The regenerator R evaporates the refrigerant in the lean solution by the above heating and separates the lean solution into refrigerant vapor and a rich solution.

The second insertion member 112 is disposed below the first insertion member 111 between the two sheets of the plate material 10. In the fourth embodiment, the space sandwiched between the first and second interposition members 111 and 112 functions as a condenser C that liquefies the vapor refrigerant generated by the regenerator R. It is desirable that the condensation heat is discharged to the outdoor side via the first plate material 10a side.

A plurality of third insertion members 113 are provided at the lower side of the second insertion member 112 at almost equal intervals between the two sheets of the plate material 10. In the fourth embodiment, the space (the lower space of the condenser C) sandwiched between the second insertion member 112 and the lower vacuum sealing member 20 is in a pressure-reduced state. That is, the plurality of third insertion members 113 serve as members for supporting the two sheets of the plate material 10 from the inside to withstand a decompressed state.

The lower space of the condenser C serves as an evaporator E and an absorber a. More specifically, the refrigerant distributor 120 that drops the liquid refrigerant obtained by the condenser C onto the inner wall of the first plate 10a is provided on the first plate 10a side of the lower space. The liquid refrigerant is dropped by the refrigerant distributor 120, and the liquid refrigerant evaporates on the first plate material 10a side to become a vapor refrigerant. Therefore, the first plate 10a side of the lower space serves as the evaporator E for cooling the first plate 10a side.

An absorbent distributor 130 for dropping the concentrated liquid obtained by the regenerator R onto the inner wall of the second plate 10b is provided on the second plate 10b side of the lower space. The concentrated liquid is dropped through the absorbent distributor 130, whereby the concentrated liquid absorbs the vapor refrigerant from the evaporator E. Therefore, the second plate material 10b side of the lower space functions as an absorber a for heating the second plate material 10b by absorbing heat.

The pump P serves as a power source for delivering the lean solution having absorbed the vapor refrigerant to the regenerator R.

In the fourth embodiment, for example, the rotation mechanism 60 shown in fig. 7 is provided, and the stacked body L can be half-rotated in the horizontal direction while maintaining the vertical direction. The configuration of the pivot window 4 according to the fourth embodiment except for the solar energy receiving part 100 and the rotating mechanism 60 (two sheets of plate materials 10, the vacuum sealing member 20, the plurality of insertion members 110, the refrigerant distributor 120, and the absorption liquid distributor 130) corresponding to the FG is referred to as a laminated body (flat body) L.

Next, the operation of the pivot window 4 according to the fourth embodiment will be described. First, as shown in fig. 10, it is assumed that the first plate material 10a is on the indoor side and the second plate material 10b is on the outdoor side.

In this case, the solar energy receiving part 100 receives solar energy. The regenerator R uses the heat received by the solar receiving portion 100, thereby evaporating the refrigerant from the weak solution and separating the evaporated refrigerant into a refrigerant vapor and a concentrated liquid. The concentrated liquid is introduced into the absorption liquid distributor 130, and the refrigerant vapor is introduced into the condenser C.

The condenser C condenses and liquefies the vapor refrigerant using air heat outside the two sheets 10. The liquefied refrigerant is introduced into the refrigerant distributor 120. The refrigerant distributor 120 drops the liquid refrigerant obtained by the condenser C onto the inner wall of the first plate 10a of the two plates. Therefore, the refrigerant evaporates on the first plate material 10a side and cools the first plate material 10a side. Therefore, a temperature control effect of cooling the room can be obtained.

The absorption liquid distributor 130 drops the concentrated liquid obtained by the regenerator R onto the inner wall of the second sheet 10b of the two sheets 10. Therefore, the vapor refrigerant from the condenser C is absorbed into the concentrated liquid and becomes the diluted liquid. The absorbed heat at this time is discharged to the room through the second plate material 10 b. Thereafter, the dilute solution is forced into the regenerator R by the pump P.

Fig. 11 is a sectional view when the laminated body L of the pivot window 3 according to the fourth embodiment is rotated by using the rotating mechanism 60. When the relative positions are switched while the vertical positions of the first plate material 10a and the second plate material 10b are maintained by using the rotating mechanism 60 as shown in fig. 7, the first plate material 10a becomes the outdoor side and the second plate material 10b becomes the indoor side as shown in fig. 11. In this case, the concentrated liquid absorbs the vapor refrigerant obtained by the condenser C, and the heat of absorption at this time heats the second plate 10b, so that a temperature control effect of heating the room can be provided. On the other hand, the refrigerant is used as a vapor refrigerant on the first plate material 10a side and cools the first plate material 10a side. The cooling heat is discharged to the outside of the room through the first plate 10 a.

As described above, according to the pivot window 4 of the fourth embodiment, in the same manner as the first embodiment, even if any one surface becomes the outdoor side, it is possible to provide the temperature control effect to the indoor side.

The temperature control effect to be provided is configured differently according to which one of the first sheet material 10a and the second sheet material 10b becomes the outdoor side. Therefore, the surface to be the outdoor side is selected according to the environment, so that the temperature adjusting effect (air conditioning effect) according to the environment can be obtained.

For example, since rotation can be performed in the horizontal direction while maintaining the vertical direction, when rotation in the vertical direction is not maintained and thus the air conditioning effect is hindered, the air conditioning effect can be exerted on the indoor side by performing rotation appropriately.

Since the first sheet material 10a side of the two sheet materials 10 is used as the evaporator E and the second sheet material 10b side thereof is used as the absorber a, the first sheet material 10a side is cooled and the second sheet material 10b side is heated. Therefore, by selecting the surface facing the indoor side, the cooling effect and the heating effect can be provided to the indoor side.

Next, a fifth embodiment of the present invention will be described. The pivot window according to the fifth embodiment has the following configuration. Hereinafter, in the description of the fifth embodiment, the same or similar elements as those of the first embodiment will be denoted by the same reference numerals.

Fig. 12 is a sectional view showing a pivot window according to a fifth embodiment. As shown in fig. 12, the pivot window 5 according to the fifth embodiment includes two sheets of the plate material 10, a sealing member 80, and a latent heat storage material 90.

The latent heat storage material 90 is formed of, for example, an inorganic salt hydrate (Na2SO410H2O and CaCl26H2O), and is enclosed and held in cavity portions of a trapezoidal-section material (a plate material in which the cavity portions serving as the cells S are arranged in the vertical direction). The latent heat storage material 90 may be encapsulated in a cavity portion of the honeycomb-section material. Each of the plurality of cells S includes a film member.

Fig. 13 and 14 are enlarged views showing one of the plurality of units S, in which fig. 13A and 14A show a first state, and fig. 13B and 14B show a second state when the unit S is half-rotated in the vertical direction. As shown in fig. 13A, film members S1 are provided at positions separated in the height direction in the cell S. The membrane member S1 is an ion exchange membrane IEM that makes the permeation rates of a specific ion and another ion different from each other. As shown in fig. 14A, the membrane member S1 may be formed of a semi-permeable membrane SPM that makes permeation speeds of ions and water different from each other.

The gas phase GP is provided in the cell S to cope with the volume change of the latent heat storage material 90. The film member S1 is disposed at a position close to the upper surface US or the lower surface BS of the cell S, and divides the interior of the cell S into a small space SS and a main space MS. As described below, even if the pivot window 5 is rotated half-way in the vertical direction, the film member S1 is disposed at a position where the film member S1 remains submerged when the latent heat storage material 90 is in a liquid state.

Here, in the pivot window 5 according to the fifth embodiment, for example, the rotation mechanism 60 shown in fig. 3 is provided, and an operation of vertically half-rotating the laminated body (flat body) L including the two plate materials 10, the sealing member 80, and the latent heat storage material 90 can be performed. The pivot window 5 can be rotated in a horizontal direction in addition to the vertical direction.

Next, the operation of the pivot window 5 according to the fifth embodiment will be described with reference to fig. 13A and 13B. In the example shown in FIG. 13, latent heat storage material 90 is formed by adding Na₂SO₄·10H₂O is obtained by adding NaCl as a freezing point depressant.

First, in winter, the orientation of the unit S is as shown in fig. 13A. That is, the ion exchange membrane IEM is in a state of being located on the lower side. Here, the ion exchange membrane IEM is, for example, a monovalent ion selective permeable anion exchange membrane. Therefore, the chlorine ions and water can permeate the ion exchange membrane IEM, and the chlorine ions and water are located in the small space SS. Thus, the concentration of the freezing point depressant in the main space MS is reduced. Accordingly, the freezing point of the latent heat storage material 90 in the unit S may be increased to, for example, about 26, and thus, a latent heat storage window providing a temperature control effect of heating a room for winter season may be obtained.

On the other hand, for example, in summer, the stacked body L is half-rotated in the vertical direction by the rotating mechanism 60 shown in fig. 3 while maintaining the left-right position of the stacked body L. In this case, the result is shown in fig. 13B. That is, most of the small space SS becomes the gas phase GP. Most of the chloride ions and water present in the small space SS in fig. 13A are transferred to the main space MS. As a result, the concentration of the freezing point depressant in the main space MS becomes high. Accordingly, the freezing point of the latent heat storage material 90 in the unit S may be lowered to, for example, about 18 ℃, and thus, a latent heat storage window for summer providing a temperature control effect of cooling a room may be obtained.

The operation of the pivot window 5 according to the fifth embodiment will be described with reference to fig. 14A and 14B. In the example shown in fig. 14, the latent heat storage material 90 is Na₂SO₄·10H₂O。

First, in winter, the orientation of the unit S is as shown in fig. 14A. That is, the semipermeable membrane SPM is in a state of being located at the lower side. Here, since the semi-permeable membrane SPM has a significantly lower ion permeation rate, water is located in the small space SS, and thus the concentration of the latent heat storage material 90 in the main space MS increases. Accordingly, the freezing point of the latent heat storage material 90 in the unit S can be increased to, for example, about 26 ℃, so that a latent heat storage window for winter providing a temperature control effect of heating a room can be obtained.

On the other hand, in summer, the stacked body L is half-rotated in the vertical direction by the rotating mechanism 60 shown in fig. 3 while maintaining the left-right position of the stacked body L. In this case, the result is shown in fig. 14B. That is, most of the small space SS becomes the gas phase GP. Most of the water present in the small space SS of fig. 14A is transferred to the main space MS. As a result, the concentration of the latent heat storage material 90 in the main space MS becomes low. Accordingly, the freezing point of the latent heat storage material 90 in the unit S may be lowered to, for example, about 18 ℃, so that a latent heat storage window for summer providing a temperature control effect of cooling a room can be obtained.

As described above, according to the pivot window 5 of the fifth embodiment, in the same manner as the first embodiment, even if any one surface becomes the outdoor side, it is possible to provide the temperature control effect to the indoor side.

The temperature control effect to be provided is configured differently according to which one of the first sheet material 10a and the second sheet material 10b becomes the outdoor side. Therefore, the surface to be the outdoor side is selected according to the environment, so that the temperature adjusting effect (air conditioning effect) according to the environment can be obtained.

Since the rotation can be performed in the vertical direction while maintaining the left-right position, for example, when the relative positions of the first plate material 10a and the second plate material 10b are switched and the vertical rotation is not performed, when a desired temperature control effect cannot be obtained on both surfaces, the desired temperature control effect can be provided to the indoor side by appropriately performing the rotation.

Since the plurality of cells S having the gas phase GP, encapsulating the latent heat storage material 90 and arranged in the height direction, and the film members S1 provided at the positions separated in the height direction are provided, the concentrations of the freezing point depressant and the latent heat storage material 90 above and below the film member S1 can be changed by performing vertical rotation, so that the melting point and the freezing point of the latent heat storage material 90 can be changed. Therefore, when the melting point and the freezing point are increased, a heating effect may be provided to the indoor side, and when the melting point and the freezing point are decreased, a cooling effect may be provided to the indoor side.

As described above, although the present invention is described based on the embodiments, the present invention is not limited to the above-described embodiments, modifications may be added within a range not departing from the spirit of the present invention, and other techniques may be appropriately combined within a possible range. Further, well-known or well-known techniques may be combined to the extent possible.

For example, the rotating mechanism 60 shown in fig. 3, 6, 7, and 9 is described in the above embodiment, and the rotating mechanism 60 is not limited to the illustrated one. In the pivot window 2 according to the second embodiment, since the upper plate 72 and the lower plate 71 of the inclined surface 70 have a point-symmetrical structure with the connecting plate 73 interposed therebetween, the inclined surface 70 can perform half rotation in the vertical direction. The pivot window 5 according to the fifth embodiment is also capable of performing half rotation in the horizontal direction.

The pivot window 2 according to the second embodiment may be provided with a spray unit for spraying mist-like moisture. For example, in the state shown in fig. 4, it is assumed that the outside air temperature is higher than the room temperature. In this case, even if the outside air temperature is high when the mist-like moisture is sprayed onto the second plate material 10b, an effect of lowering the second plate material 10b to be close to the dew point can be obtained. As a result, a state similar to that when the outdoor air temperature is artificially lowered is generated, so that the cooling effect can be provided to the indoor side. The same applies to the third embodiment.

In the first embodiment, the two sheets of sheet material 10 are formed of a water vapor permeable material, but not limited thereto. The two sheets of sheet material 10 may be formed of a material that is impermeable to water vapor. In this case, for example, pipes are connected to the first and second triangular prisms 31 and 41, respectively, so that when the moisture absorbing liquid Li is regenerated, water vapor can be discharged to the outside of the room through the pipes. Moisture from the room is configured to be able to be sucked into the hygroscopic liquid Li through the pipe.

Although various embodiments have been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited to such examples. It is apparent that those skilled in the art can make various changes or modifications within the scope of the claims and it is naturally understood that these changes or modifications also fall within the technical scope of the present invention. Further, the respective components in the above-described embodiments may be freely combined with each other within a scope not departing from the spirit of the present invention.

The present application is based on japanese patent application (application No. 2017-248817) filed on 26.12.2017, the entire contents of which are incorporated herein by reference.
