Technical Field

The invention relates to a ventilation device for ventilating and aerating at least one space of a building according to the preamble of claim 1. The invention relates in particular to a ventilation device having a heat accumulator unit for heat transfer from a ventilation medium flow to a ventilation medium flow, having a closing and opening device for controlling an air flow path, wherein a filter element is arranged in the air flow path.

Background

A ventilation device of this type is known from DE 3207761 a 1. The invention relates to a ventilation and air-exchange system with exhaust heat recovery for living and parking spaces, offices, schools, warehouses and work spaces, comprising a box-shaped housing that can be mounted on a wall and/or in a central ceiling, wherein two radial fans are provided for separately supplying and discharging an air flow. For intake and exhaust, one memory bank each is used as a heat exchanger. The plates of these memory banks are in direct contact with intake air or exhaust air depending on the switching state. In the case of continuous operation of the radial fan, depending on the thermal state of the storage group, a change in direction of the air flow is achieved in the region near the boundary layer of the heat transfer between the storage group and the air flow by means of a controllable air flap by means of a continuous change in the velocity vector of the air flow within the storage group.

In the known ventilation device, the orientation of the air flows for the intake and exhaust air is not properly assigned to one side for the air exchange due to the arrangement inside the ventilation device, so that outside the ventilation device additional work must be done by means of channel deflection. Additional channel deflection requires additional installation space, which can be a hindrance.

Furthermore, an air technology system according to DE 202012010671U 1 is known from the prior art, which is provided for ventilating and ventilating at least one space of a building. For this purpose, the air technical system has two air channels, which each have a channel opening on the inlet side and on the outlet side and are fluidically interconnected between the associated channel openings by having an air conveying device, and a closure device, which fluidically connects one channel opening of a first air channel to one channel opening of a further second air channel in a first operating mode for forming a first air path which is guided via the air conveying device. Furthermore, the closure device fluidically connects a further channel opening of the first air channel to a further channel opening of the second air channel in a second operating mode for forming a second air path which is guided via the air conveying device.

This known ventilation device is structurally designed such that the closure device comprises a ventilation slide, by means of which the respective operating mode is controlled in a rotary motion. The temporal sequence for adjusting the closure device into the selected operating mode by means of the ventilation slide is periodic, so that the air exchange is interrupted during this time, which can adversely affect the air exchange and disturb the persons located in the space due to the constantly alternating noise. Furthermore, the heat exchanger and the filter element are alternately traversed, wherein, by dividing the air throughflow of the ventilation and ventilation medium flows through the heat exchanger in half, even only half of the available storage capacity is used, which has an adverse effect on the degree of heat recovery. Furthermore, it has proven to be disadvantageous that the filter element is flowed through alternately by the ventilation and ventilation medium flows. Dirt particles which have been sucked out of the space by the ventilation medium flow are again conducted into the space by the ventilation medium flow.

Disclosure of Invention

The object of the present invention is to provide a ventilation device of the type mentioned at the outset, which overcomes the disadvantages of the prior art. At the same time, high air output, good sound damping, low intrinsic noise and a high degree of heat recovery should be achieved with this ventilation device.

According to the invention, the solution to this problem is achieved according to the characterizing part of claim 1 in that the housing of the ventilation device forms an upper plane and a lower plane in height, separated by an intermediate floor. Furthermore, the housing is divided over its length in the upper plane by the closing and opening device and the lower plane is divided by means of a partition wall, so that two upper air flow channels and two lower air flow channels are formed. In addition, the air supply device, which is composed of an intake fan for the ventilating medium flow and an exhaust fan for the ventilating medium flow, runs continuously in the air supply direction and connects the upper level to the lower level. Furthermore, the upper air flow channel has a heat accumulator unit in each case on the upper plane toward the side of the housing, wherein a feed filter element is assigned in each case between the heat accumulator unit and the outside, which feed filter element can be flowed through the air flow channel continuously and in a completely alternating and reversing manner by the ventilation and ventilation medium flows through the closing and opening device. In this case, the air flow channel is constantly traversed in the lower plane by the ventilation and ventilation medium flows. This makes it possible to maintain a constant volume flow rate while maintaining pressure stability for the ventilation medium flow discharged from the inside of the space and the ventilation medium flow supplied to the interior of the room. Since two heat accumulators are arranged in the upper plane, which are alternately switched on separately from one another by upstream closing and opening devices, a constant flow of ventilation and ventilation medium to the outside and from the outside to the inside of the space can be maintained with almost constant fan power.

In order to increase the efficiency and to make full use of the heat recovery device, in a preferred embodiment of the ventilation device, an inlet and an outlet are provided on the upper plane of the housing on the side facing the outside for the respective ventilation and ventilation medium flows of the upper air flow channel, so that in the operating state at least two heat accumulators arranged continuously flow over the entire area at the respective inlet and outlet alternately through by the ventilation and/or ventilation medium flows. The ventilation medium flow heated by the exhaust gas from the inside of the space can thus be distributed over the entire area of the heat accumulator during the flow-through, which stores heat and, correspondingly, as the direction of the air flow through the closing and opening device changes, outputs the stored heat again to the reverse flow of the air of the ventilation medium flow, likewise over the entire cross section of the heat accumulator.

In an advantageous manner, an outlet opening for the ventilating medium flow of the lower air flow duct and an inlet opening for the ventilating medium flow of the lower air flow duct are provided on the side facing the inside of the space of the housing on the lower plane. Due to the design of the lower air flow channel, a continuous separation of the ventilation medium flow and the ventilation medium flow can be established on the inside of the space.

In order to be able to easily clean or replace the filter element, an exhaust filter element is arranged on the side of the housing in the region of the inlet of the lower air flow channel, said exhaust filter element being permanently flowed through by the ventilation medium on one side. The exhaust filter element is also responsible for the ventilation medium flow, through which the dirt particles are removed, and the components which flow through the ventilation device. Thereby avoiding possible accumulation of dirt in the air flow channel and the heat accumulator. Cleaning or replacement of the exhaust filter element is effected by simply pulling out the filter holder constructed as a box, which is positioned in the lower plane of the air guide module.

A further advantageous embodiment of the ventilation device is achieved in that the intake fan is arranged in the lower plane of the housing, while the exhaust fan is directed towards the upper plane of the housing. This arrangement provides as large a construction space as possible for the respective blower and carefully separates the two components for air supply.

For optimal installation and removal from the inside of the space, for example for cleaning purposes, the housing is divided modularly into three sections over the length of the ventilation device, wherein the middle section provides the technical module and the outer sections each provide the air guiding module. Thus, each individual component forms a defined end position with sliding in the housing, wherein at the same time by dividing the segments the weight of the entire ventilation device is distributed over the module components, which results in further advantages for mounting and dismounting.

In particular in the technical module, a possible fine adjustment of the ventilation device can be carried out simply. For this purpose, all functional and regulating components, such as closing and opening devices, exhaust and intake fans and control units, are arranged in the technical module. The air flow channel, the heat accumulator unit and the exhaust and intake filter element are preferably arranged in the air guide module. The heat accumulator located in the air flow channel takes up the temperature of the air with a constant flow of air through it (as specified by the design of the ventilation device). The heat accumulator cools down if, for example, a cooler flow of ventilation medium is drawn in from the outside. When the ventilation medium flow then flows from the inside of the space to the outside, the heat accumulator cools the ventilation medium flow and is heated there. When the air flow direction is reversed again, the heat accumulator acts like a heat exchanger and heats the intake air and cools it again. A regenerator is very suitable for a process, which is made of a storage mass of ceramic, metal or made of a synthetic material and comprises a plurality of channels. The storage mass, which is ceramic, metallic or made of a synthetic material, has a high thermal capacity, since the heat accumulator of the ventilation device dries the moisture that may form by heating due to the regular and transition-free spacing of the ventilation and ventilation medium flows. Preferably, the heat accumulators are of identical construction, which prevents confusion during installation and which has a positive effect on the balancing of the functionality during the operating state of the ventilation device. In addition, the outlet filter element is continuously traversed by the ventilation medium flow in the lower plane, while the air supply direction remains unchanged, wherein two further inlet filter elements in the upper plane are periodically traversed alternately by the ventilation and ventilation medium flows in front of the heat recovery device facing the outside. The exhaust filter element prevents contamination of the heat recovery device by air drawn from the inside of the space, wherein the service time or life is increased. All components flowing through the air, such as the air flow channel, the heat accumulator unit, the air supply device and the closing and opening device, are protected from external influences, for example dirt particles of air and/or pollen, by the upstream filter element.

According to a further development of the invention, the division of the segments of the module is achieved by means of two partition walls, wherein the partition walls have an air flow interruption which is adapted to be in operative connection with the air flow channel. The partition walls together with the housing provide complete accommodation possibilities for mounting and dismounting to all sides of the module in the manner of a drawer system. Guide means for simplified displacement of the modules on the partition walls are likewise conceivable. Furthermore, the ventilation device has a length-wise stability of the base frame of the housing achieved by the partition wall.

In order to achieve a noise-free and virtually transition-free switching from the ventilation medium flow to the ventilation medium flow, the closing and opening device arranged on the upper plane of the housing has a closing mechanism, which is preferably formed by a ventilation slide, for opening and closing an air flow channel for the ventilation and ventilation medium flow, wherein an opening for a permanent air flow course is provided on the lower plane of the separating wall.

A further advantageous feature of the closing and opening device provides that, in order to produce an almost continuous air guidance, the ventilation slider is operated by the rack drive in a correspondingly rapidly closing and/or a correspondingly rapidly opening manner. For this purpose, the end positions of the ventilation slides are spaced diagonally apart on the respective side of the blower, which ventilation slides simultaneously form the closed or open state of the air flow channel assigned to the upper plane and thereby influence the ventilation and ventilation medium flow. The rack drive increases the closing effect when the direction of the ventilation slide changes and thus increases the reliability of the drive system of the ventilation device.

For actuating the ventilation slide, the closing and opening device preferably has an electrically motorized drive. The ventilation slides can advantageously be controlled separately from one another by means of in each case one drive, so that the operating state of the ventilation device can be selected by the control unit for ventilation and ventilation or for example for complete closure. The transmission of the drive to the ventilation slider is effected by a spur gear which is operatively connected to the control unit and which is operatively connected to a toothed rack arranged on the ventilation slider and allows a linear reciprocating movement of the ventilation slider.

Functionally, it is important for the ventilation device and is inexpensive to produce that the ventilation slide is accommodated in the recess guided on the side of the housing and is arranged directly next to the intake fan and the exhaust fan. As the closing and opening device is switched on and off by the ventilation slider, for example, the first ventilation slider with the arranged first heat accumulator is in a mode of the ventilation medium flow, wherein the second heat accumulator to the other arranged ventilation slider is simultaneously kept in a mode of the ventilation medium flow. After each switching operation of the closing and opening device, the ventilation slide is changed from one side of the housing to the other side, so that the arranged heat accumulator units are alternately flowed through.

Furthermore, the ventilation device has proven to be cost-effective and simple to install in that the closing and opening device is used in two positions without any structural change. The only difference is the switching position with the ventilation slide which, during the operating state, changes in a periodic direction to the respective side of the housing with different end positions. In a first operating state, the ventilation slider arranged on the half of the ventilation device that is separated from the center plane is therefore in the end position of the open ventilation medium flow and flows through the one heat accumulator, wherein the ventilation slider arranged on the other half of the ventilation device is in the end position of the open ventilation medium flow and flows through the other heat accumulator. The second operating state is set as a function of the end position of the ventilation slide, so that the respective heat accumulator flows through from the opposite direction by changing the direction of the ventilation and scavenging medium flows in the upper plane.

The ventilation slides of the closing and opening devices are actuated by an electrically operated drive, which can be controlled separately from one another, so that the operating state of the ventilation device can be selected by a control unit, which has a circuit board to which all the driven components are electrically connected, in order to ventilate and ventilate the air path or, for example, to completely close it. Preferably, all electronic components and all movably driven components are arranged in the technical module, so that, for example, only the technical module is removed from the housing of the ventilation device for the purpose of servicing the above-mentioned components.

According to a further development of the invention, it is provided that the blower of the air supply device, which blower continuously operates in the direction of rotation during the operating state, is a radial fan. In order to achieve a desired volume flow, a high pressure stability and a volume flow which is as constant as possible, a radial fan is preferably used. Furthermore, the continuous operation results in a relatively low operating cost and protects the air conveying device, so that it operates with little wear and little noise.

The vertical center plane of the ventilation device forms a central arrangement of the spatially separated fans. In this case, the fans are arranged offset from one another on the center plane and provide sufficient space for simple installation and sufficient insulating material for insulation and also dimensioning of the fans, which results in a low intrinsic noise and a long, aerodynamically oriented air flow channel for the sound absorption. With a symmetrical design of the ventilation device on the center plane and by arranging one blower on the outside of the housing and the other blower on the side of the chamber of the housing, the greatest possible distance from the filter element and from the heat accumulator is obtained. In addition to the favorable air flow conditions, this also results in a longer dwell time of the air flow and a better heating of the supplied ventilation medium flow through the housing in this connection.

The housing of the ventilation device advantageously encloses all the functional components, which can be mounted and dismounted in a simple and quick displaceable manner in a fixed position. The integrated functional component in the housing is arranged completely covered in the installed state. Contamination that could lead to a deterioration of the service life of the ventilation device is eliminated by the sealed connection of the housing. It is also possible to remove the filter element belonging to the air guide module from the housing for possible maintenance in a simplified manner by moving it and, if necessary, cleaning it.

In order to achieve an increased sound damping and to make the best possible use of the available space requirement of the functional component, the housing has an outlet for the flow of the ventilation medium and an inlet for the flow of the ventilation medium on the side facing the inside of the space. The inlet and outlet for the flow of ventilation and scavenging medium are arranged on the side facing the outside of the housing.

The invention further relates to a method for operating a ventilation device for ventilating and ventilating a space of a building, wherein a blower and a heat accumulator are provided in a ventilation and ventilation medium flow, wherein a temperature exchange of the ventilation and ventilation medium flow is achieved by alternately flowing through the heat accumulator, wherein an alternating flow through the heat accumulator is achieved by exchanging ventilation paths of the ventilation and ventilation medium flow in an upper plane of a housing of the ventilation device, with a conveying direction of the blower being maintained, and wherein the ventilation and ventilation medium flow is constantly flowed through in a lower plane by maintaining an air flow channel to the blower.

Detailed Description

Fig. 1 of the accompanying drawings shows a perspective view of a ventilation device 1 with a housing 2 for simultaneously ventilating and ventilating a space. The ventilation device 1 can be fastened according to fig. 1, preferably from the inside 5 of the space or also, as required, from the outside 7, in a building wall 3, which can be designed in particular as a facade wall. The building wall 3 has a through-opening towards the outside 7, which is likewise considered for windows or doors. The ventilation device 1 can also be used in specially designed through openings in the building wall 3.

Fig. 1 and 2 furthermore show that the housing 2 of the ventilation device 1 is separated in height H by an intermediate floor 13 to form an upper plane 14 and a lower plane 15, wherein the intermediate floor 13 is constructed in three parts. The housing 2 according to fig. 2 is divided in the upper plane 14 again by the closing and opening device 12 by the total length L and the lower plane 15 is divided by means of the partition wall 16, whereby two upper air flow channels 17, 18 and two lower air flow channels 19, 20 result.

Proceeding from fig. 3 to 8, the air supply device 8 here comprises an intake fan 21 for the ventilation medium flow 9 and an exhaust fan 22 for the ventilation medium flow 10, which operate continuously in the air supply direction and connect the upper plane 14 to the lower plane 15 for the air flow. Furthermore, the upper air flow channels 17, 18 each have a heat accumulator unit 11 on the upper plane 14 toward the side 6 of the housing 2. Between the heat accumulator unit 11 and the outer side 7 of the upper plane 14, in each case according to fig. 3 and 5, an intake air filter element 23 is associated, which is continuously flowed through the air flow channels 17, 18 in a completely alternating and opposite manner by the ventilation and gas exchange medium flows 9, 10 with the upstream closing and opening device 12. In this case, the air flow channels 19, 20 are constantly flowed through by the ventilation and ventilation medium flows 9, 10 in the lower plane 15 according to fig. 4 and 6. This achieves that the ventilation medium flow 10 discharged from the space interior 5 and the ventilation medium flow 9 fed into the interior 5 maintain a constant volume flow while maintaining pressure stability. Since the two heat accumulators 11 according to fig. 3 and 5 are arranged in the upper plane 14, which in turn can be alternately switched apart from one another by the upstream closing and opening device 12, it is possible to maintain the constant continuous ventilation and ventilation medium flows 9, 10 toward the outside 7 and from the outside 7 toward the space interior 5, with the power of the blowers 21, 22 almost continuously identical.

In order to increase the efficiency and to make full use of the heat recovery device, inlet and outlet openings 24, 25 are provided in the ventilation device 1 for the respective ventilation and ventilation medium flows 9, 10 of the upper air flow channels 17, 18 on the side 6 facing the outside 7 of the housing 2 on the upper plane 14 according to fig. 3 and 5, respectively, so that the at least two heat accumulators 11 arranged in the operating state are alternately flowed through by the ventilation and/or ventilation medium flows 9, 10 continuously over the entire area at the respective inlet and outlet openings 24, 25. The ventilation medium flow 10 heated by the exhaust gas from the space interior 5 can thus be distributed over the entire area of the heat accumulator 11 during the flow-through, which stores heat and accordingly, with a change in the direction of the air flow through the closing and opening device 12 of fig. 3 and 5, outputs the stored heat again through the entire cross section of the heat accumulator 11 to the reverse flow-through of the air of the ventilation medium flow 9.

According to fig. 4 and 6, an outlet 26 is provided for the ventilating medium flow 9 of the lower air flow duct 19 and an inlet 27 is provided for the ventilating medium flow 10 of the lower air flow duct 20 on the lower plane 15 on the side 4 facing the space inside 5 of the housing 2. A continuous separation of the ventilation medium flow 9 and the ventilation medium flow 10 is established on the space interior 5 by means of the lower air flow channels 19, 20.

In relation to the side 4 of the housing 2, in the region of the inlet 27 of the lower air flow duct 20 according to fig. 4 and 5, an exhaust filter element 28 is arranged, which is permanently traversed on one side by the ventilation medium flow 10. The exhaust filter element 28 is also responsible for the ventilation medium flow 10, through which the dirt particles are removed, and the components which flow through the ventilation device 1. A possible accumulation of dirt in the air flow channels 17, 18, 20 and the heat accumulator 11 is thereby avoided. Cleaning or replacement of the exhaust filter element 28 can be achieved by simply pulling out from the inside of a space configured as a box, not shown, of a filter holder, which is positioned in the lower plane of the air guide module.

Furthermore, the intake fan 21 according to fig. 4 and 6 is arranged in the lower plane 15 of the housing 2, while the exhaust fan 22 according to fig. 3 and 5 faces the upper plane 14 of the housing 2. The division in the respective plane 14, 15 provides for a complete utilization of the power of the blower 21, 22 in the design of the blower 21, 22 which is as large as possible.

It is also clear from fig. 2 that, for example for cleaning purposes, the housing 2 is divided modularly from the space interior 5 over the length L of the ventilation device 1 into three sections 29, 30, 31, wherein the middle section 30 provides the technical module 32 and the outer sections 29, 31 each provide the air guiding module 33. Each individual section 29, 30, 31 is therefore mounted in the housing 2 in such a way that it can be introduced into the housing in a movable manner and removed therefrom when required. By separating the sections 29, 30, 31, the weight is distributed to the components, which is shown as a further advantage for mounting and dismounting.

In particular in the technical module 32 according to fig. 7 and 8, a possible fine adjustment of the ventilation device 1 can be carried out simply. For this purpose, all functional and regulating components, such as the closing and opening device 12, the exhaust and intake fans 21, 22 and a control unit 34 with a circuit board for coupling the electrically operated drives and sensors, are accommodated in the technical module 32. Preferably, in the air guide module 33 according to fig. 3 to 6, air flow channels 17, 18, 19, 20, the regenerator unit 11 and the exhaust and intake filter elements 23, 28 are arranged. The heat accumulator 11 located in the air flow channels 17, 18, 19, 20 receives the temperature of the air with a constant flow of air (as specified by the design of the ventilation device 1). The heat accumulator 11 cools if, for example, a cooler ventilating medium flow 9 is drawn in from the outside 7. When the ventilation medium flow 10 then flows from the space interior 5 to the exterior 7, the heat accumulator 11 cools the ventilation medium flow 10 and is heated there. When the air flow direction is reversed again, the heat accumulator 11 acts like a heat exchanger, heats the intake air and cools itself again there.

The heat accumulator 11 is well suited for processes which consist of a ceramic or metallic storage substance and which comprise a plurality of channels. Ceramic, metallic or plastic storage masses achieve a high thermal capacity due to the material selection and shaping. Due to the regular and transition-free spacing of the ventilation and ventilation medium flows 9, 10, the heat accumulator 11 of the ventilation device 1 is dried by heating due to high heat absorption in the event of possible moisture formation. The heat accumulator 11 according to fig. 3 and 5 is preferably shown in a plan view and in a front view in fig. 2, and is of identical design, which prevents confusion during installation and which has a positive effect on the functional balance during the operating state of the ventilation device 1. A plurality of regenerators 11 may also be separately arranged in the air flow channels 17, 18, 19, 20, as required.

It can also be seen from fig. 4 and 6 that, while maintaining a constant air supply direction, the outlet filter element 28 is continuously traversed by the ventilation medium flow 10 in the lower plane 15, wherein two further inlet filter elements 23 according to fig. 3 and 5 are periodically traversed alternately by the ventilation and ventilation medium flows 9, 10 in the upper plane 14 in front of the heat recovery device on the outside 7. The exhaust filter element 28 prevents contamination of the heat recovery device by air drawn out of the space interior 5, wherein the intake filter element 23 is self-cleaned by continuously changing the air conveying direction. All components flowing through the air, such as the air flow channels 17, 18, 19, 20, the heat accumulator unit 11, the air supply device 8 and the closing and opening device 12, are protected from external influences, such as dirt particles of air and/or pollen, by the upstream filter elements 23, 28.

According to fig. 2 to 8, the sections 29, 30, 31 are divided by means of two partition walls 35, 36, wherein the partition walls 35, 36 have an air flow interruption 37, 38, 39, 40, which is in adapted transitional operative connection with the air flow duct 17, 18, 19, 20.

The partition walls 35, 36 are connected to the housing in a form-fitting and/or force-fitting manner and with the housing 2 provide complete accommodation possibilities for mounting and dismounting to all sides of the modules 32, 33 in the manner of a drawer system. Guide means for simplified displacement of the modules 32, 33 on the partition walls 35, 36 are likewise conceivable.

According to fig. 7 and 8, the closing and opening device 12 arranged on the upper plane 14 of the housing 2 has a noise-free and virtually transition-free switching from the ventilation medium flow 9 to the ventilation medium flow 10 by means of a closing mechanism formed by ventilation slides 41, 42 for opening and closing the air flow channels 17, 18 for the ventilation and ventilation medium flows 9, 10. In contrast, according to fig. 4 and 6, openings 43, 44 for a permanent air flow course are provided in the lower plane 15 of the separating wall 16.

In the closing and opening device 12 shown in fig. 7 and 8, it is provided that, in order to generate an almost continuous air guidance, the ventilation sliders 41, 42 are operated by a rack drive 45 in a correspondingly rapidly closing and/or a correspondingly rapidly opening manner. For this purpose, the end positions of the ventilation sliders 41, 42, which simultaneously form the closed or open state of the air flow ducts 17, 18 assigned to the upper plane 14 and thereby influence the ventilation and ventilation medium flows, are spaced diagonally apart on the respective sides of the blowers 21, 22. The rack drive 45 increases the closing effect when the direction of the ventilation sliders 41, 42 is changed, and thus increases the reliability of the drive system of the ventilation device 1.

Continuing with fig. 7 and 8, for actuating the ventilation sliders 41, 42, the closing and opening device 12 preferably has an electrically motorized drive which is directly connected to a spur gear 47. The ventilation slides 41, 42 can be controlled separately from one another by means of a respective drive on each spur gear 47, so that the operating state of the ventilation device 1 can be selected for ventilation and air exchange of the air path by the control unit 34 or, for example, for completely closing the air path. The transmission of the drive to the ventilation sliders 41, 42 is thus effected via a spur gear 47 which is in operative connection with the control unit 34, which spur gear in turn is effected with a toothed rack 46 arranged on the ventilation sliders 41, 42 and permits a linear reciprocating movement of the ventilation sliders 41, 42.

The ventilation sliders 41, 42 are accommodated according to fig. 7 and 8 so as to be guided in a displaceable manner in recesses 48, 49 on the side faces 4, 6 of the housing 2 and are arranged directly next to the intake and exhaust fans 21, 22. With the switching of the closing and opening device 12 by the ventilation sliders 41, 42, for example, the first ventilation slider 41 with the first heat accumulator 11 arranged according to fig. 7 is in the mode of the ventilation medium flow 9, wherein the second heat accumulator 11 to the other arranged ventilation sliders 42 is simultaneously maintained in the mode of the ventilation medium flow 10. After each switching process of the closing and opening device 12, the ventilation slides 41, 42 change from one side 4 to the other side 6 of the housing 2, so that the arranged heat accumulator units 11 flow alternately through.

According to fig. 3 to 8, the closing and opening device 12 is used beside the blowers 21, 22 in two fixed positions without structural changes. The ventilation sliders 41, 42 have different end positions during the change of the operating state in a periodic direction to the respective side 4, 6 of the housing 2. In the first operating state, when the ventilation slider 41, which is arranged on the half of the ventilation device 1 that is spaced apart from the center plane 50, is in the end position of the open ventilation medium flow 9 and flows through the heat accumulator 11, the ventilation slider 42, which is arranged on the other half of the ventilation device 1, is responsible for flowing through the other heat accumulator 11 in the end position of the open ventilation medium flow 10. The second operating state is set as the end position of the ventilation sliders 41, 42 changes, so that the respective heat accumulator 11 flows through from the opposite direction by changing the direction of the ventilation and ventilation medium flows 9, 10 in the upper plane 14.

The electrically operated drives, which are not shown in the figures, arranged at the respective ventilation slides 41, 42, control the ventilation slides 41, 42 separately from one another, so that the operating state of the ventilation device can be selected by the control unit 34 for ventilation and air exchange or for complete closure, for example. For this purpose, the control unit 34 has a circuit board, to which all drive components are electrically connected. All electronic components, for example also sensors and all movably driven components, are arranged in the technical module 32, so that the technical module 32 can only be removed from the housing 2 of the ventilation device 1 by an authorized professional, for example for the purpose of maintaining the above-mentioned components.

The fans 21, 22 of the air supply device 8, which fans operate continuously in the direction of rotation during the operating state, are radial fans which achieve a suitable target volume flow, high pressure stability and a volume flow which remains as constant as possible. Furthermore, the continuous operation results in a relatively low operating cost and protects the air conveying device, so that it operates with little wear and little noise.

The vertical center plane 50 of the ventilation device 1 according to fig. 7 and 8 forms a central arrangement of the spatially separated fans 21, 22. In this case, the fans 21, 22 are arranged offset from one another on the center plane 50 and provide sufficient positions for simple assembly and for sufficient insulation material for insulation and for dimensioning of the fans 21, 22, as a result of which low inherent noise of the fans 21, 22 and an elongate course of the air flow channels 17, 18, 19, 20 with an aerodynamic course for sound absorption are achieved. The insulating material thus lines the air flow channels 17, 18, 19, 20 or forms the air flow channels 17, 18, 19, 20. Furthermore, the housing cover of the housing 2 is at least partially covered on the inside by an insulating material. By means of the insulation, the ventilation device 1 acts acoustically (in order to avoid the transmission of structure-borne sound and noise from the outside), mechanically and thermally damped.

With the maintenance of the symmetrical configuration of the ventilation device 1 on the central plane 50 and with the arrangement of one blower 21 relative to the side 6 and the arrangement of the other blower 22 on the side 4 of the housing 2, the greatest possible distance is obtained relative to the filter elements 23, 28 and relative to the heat accumulator 11, respectively.

According to fig. 1 and 2, the housing 2 encloses, in a protective and compact manner, all the functional components of the ventilation device 1, which can be mounted and removed in a positionally fixed manner in the housing 2 in a simple and rapid manner. The integrated functional components in the housing 2 are arranged completely covered in the installed state. Contamination that could lead to a deterioration of the service life of the ventilation device is eliminated by the sealed connection of the housing. In a simplified manner, the filter elements 23, 28 belonging to the air guide module 33 can also be removed and possibly cleaned by removing the technical module 32 from the housing 2 for possible maintenance, also by a layperson.

In fig. 3 to 6 and 10, the housing 2 has an outlet 26 for the ventilating medium flow 9 and an inlet 27 for the ventilating medium flow 10 on the side 4 facing the space inside 5. On the side 6 of the housing 2 towards the outside 7, there are arranged an inlet and an outlet 24 and 25, respectively, for the ventilating and scavenging medium flows 9, 10.

In summary, a method for operating a ventilation device 1 for ventilating and ventilating a space of a building is obtained, wherein a blower 21, 22 and a heat accumulator 11 are provided in a ventilation and ventilation medium flow 9, 10, wherein a temperature exchange of the ventilation and ventilation medium flow 9, 10 is achieved by alternately flowing through the heat accumulator 11, wherein an alternate flow through the heat accumulator 11 is achieved by exchanging ventilation paths of the ventilation and ventilation medium flow 9, 10 in an upper plane 14 of a housing 2 of the ventilation device 1, with a conveying direction of the blower 21, 22 being maintained, and wherein the ventilation and ventilation medium flow 9, 10 is constantly flowed through in a lower plane 15 by maintaining an air flow channel 19, 20 leading to the blower 21, 22.
