Technical Field

Background

The passive building technology is an important measure for reducing building energy consumption and building a comfortable indoor environment. As a typical passive building energy-saving technology, the heat collection wall system can absorb solar radiant heat, produce a chimney effect and induce indoor passive ventilation, and can be theoretically used for heating and ventilation cooling of the indoor environment of the building.

The heat collecting wall system adopted in the prior building is mainly used for heating in cold weather in winter, and the aim of ventilating and cooling is difficult to achieve really under hot weather conditions in summer, which is mainly caused by the poor adaptability of the structural characteristics of the heat collecting wall system to the weather environment. The heat collection wall is also called as a special lambert wall and generally comprises a glass cover plate, a heat absorption plate, an air channel and a common wall body, wherein ventilation openings are formed in the upper part and the lower part of the glass cover plate, the heat absorption plate and the common wall body. In winter, the upper and lower ventilation openings on the outer side of the room are closed, the upper and lower ventilation openings on the inner side of the room are opened, the heat absorption plate absorbs solar radiation heat to heat and conduct convection heat, indoor cold air is induced to enter the air channel to be heated and circulated, and the temperature of the indoor air is increased. In summer, the outdoor lower ventilation opening and the indoor upper ventilation opening are closed, the outdoor upper ventilation opening and the indoor lower ventilation opening are opened, the heat absorption plate absorbs solar radiation heat to raise temperature and conduct heat in a convection mode, indoor air is induced to flow out of the room through the air channel and the outdoor upper ventilation opening, meanwhile negative pressure is formed in the room to induce outdoor air to flow out of the room through the door and window, and therefore the purposes of indoor ventilation and cooling are achieved. However, when the solar heat collector is used in summer, the outdoor environment temperature is high, the capacity of the heat collecting wall system for driving indoor air to flow and ventilate by utilizing the chimney effect manufactured by temperature difference is very limited, and redundant heat can enter the indoor space through the indoor side lower ventilation opening and the common wall body, so that the indoor temperature is increased. In addition, when the outdoor temperature is low in rainy days in summer, the heat collection wall system cannot utilize solar radiation heat, the area of the ventilation opening is small, the overall thermal resistance of the structure is large, and the heat collection wall system is not beneficial to transferring indoor heat to the outdoor to reduce the temperature and ventilate the indoor. Obviously, the existing heat collection wall system is not suitable for summer climate and cannot fully utilize natural wind to improve the passive ventilation and cooling capacity of the building.

Therefore, an intelligent regulation type heat collecting wall system which can adapt to summer climate and fully utilize natural wind to improve the passive ventilation and cooling capacity of a building is needed.

And a glass cover plate 4 is arranged on the outer side of the wall body 1, wherein the glass cover plate is a low-e double-layer hollow glass cover plate. The upper and lower parts of the glass cover plate 4 are provided with a third ventilation opening 2 and a fourth ventilation opening 8 which are respectively in convection with the first ventilation opening 11 and the second ventilation opening 13, and the third ventilation opening 2 and the fourth ventilation opening 8 are respectively provided with a third air volume regulating valve 3 and a fourth air volume regulating valve 9. The third air volume adjusting valve 3 and the fourth air volume adjusting valve 9 are controlled by the intelligent control processing unit, and can execute corresponding opening and closing actions according to control signals sent by the intelligent control processing unit so as to realize the opening and closing of the third air inlet 2 and the fourth air inlet 8.

The outer side face of the wall body 1 is paved with a heat insulation plate 7, the outer side face of the heat insulation plate 7 is attached to a heat absorption plate 6, and the heat insulation plate 7 is used for reducing heat transfer from the heat absorption plate 6 to the interior of a building; an air channel 5 is formed between the heat insulation plate 7 and the glass cover plate 4; the side of the heat absorbing plate 6 facing the air channel 5 is sprayed with black paint, which facilitates maximum absorption of solar radiation heat.

Two side surfaces of the air channel 5 are symmetrically provided with a first-stage guide plate 19, and two ends of the first-stage guide plate 19 are respectively connected with the glass cover plate 4 and the wall body 1. The first-stage guide plate 19 can adopt an automatic or manual adjusting rainproof shutter air port, or adopt a detachable movable baffle plate and other devices with wind guiding and rainproof functions.

The outside of air channel 5 is installed second grade guide plate 17, and second grade guide plate 17 installs on rotation axis 18, and rotation axis 18 is fixed in the wall body outside. The secondary air deflector 17 can be a manual air deflector, or an automatic or manual sun shield, and other devices capable of achieving air guiding function.

The second-stage air deflector 17 can rotate around the rotating shaft 18, the angle is automatically adjusted, outdoor natural air is guided to the maximum degree to enter the air channel 5 through the first-stage air deflector 17, and enters the indoor space of the building through the first ventilation opening 11, the second ventilation opening 13, the third ventilation opening 2 and the fourth ventilation opening 8. The top of the rotating shaft 18 is provided with a weather station 16, the weather station 16 is a small weather station and is used for detecting and outputting data signals such as solar radiation intensity, atmospheric temperature, wind speed, wind direction, rainfall and the like, and transmitting the data signals to the intelligent control processing unit, and the intelligent control processing unit sends appropriate working instruction signals to each controlled component according to the data detected by the weather station 16. The first-stage guide plate 19 and the second-stage guide plate 17 are controlled by the intelligent control processing unit, and can execute corresponding opening and closing actions according to control signals sent by the intelligent control processing unit so as to realize air guide. The rotating shaft 18 is controlled by the intelligent control processing unit and can execute corresponding rotating actions according to control signals sent by the intelligent control processing unit.

An electric sunshade curtain 10 is installed on the outer side of the glass cover plate 4, a track 15 is connected to the side edge of the electric sunshade curtain 10, and the track 15 is fixedly installed on the wall body 1. The electric sunshade 10 is controlled by the intelligent control processing unit and can perform corresponding lifting actions according to control signals sent by the intelligent control processing unit.

In practical application, on a sunny day with intense sunlight, the electric air volume regulating valves 9 and 12 are closed, the electric air volume regulating valves 3 and 14 are opened, and the primary air deflector 19 is closed. When the solar radiation intensity signal detected by the small weather station 16 exceeds the set value, the electric sunshade curtain 10 automatically moves to the right middle position of the glass cover plate 4 along the track 15. At this time, the temperature of the solar radiation heat transmitted from the upper half part of the heat absorbing plate 6 through the upper half part of the glass plate 4 is increased, and the air contacting with the air channel 5 is heated through convection heat transfer, because the glass cover plate 4 is shielded by the electric sunshade curtain 10, the air temperature of the air channel 5 contacting with the lower half part of the heat absorbing plate 6 is relatively low, and the heat absorbed by the heat absorbing plate is prevented from being transmitted into the room through the second ventilation opening 13. Under the action of the thermal floating lift force caused by the temperature difference, air in the air channel 5 flows into the outdoor through the air vent 2, meanwhile, indoor air is sucked into the air channel 5 through the second air vent 13, and air with relatively low temperature at the shady and cool position on the north side of the building enclosure structure is sucked into the building through the door and the window under the action of indoor micro negative pressure to form circulating ventilation in the building, so that the thermal comfort degree of the indoor environment is improved.

In practical application, on cloudy days with weak sunlight, the outdoor air temperature is lower than that in the room, the electric air volume regulating valves 3, 9, 12 and 14 are all opened, and the air with the lower outdoor temperature is enhanced to the greatest extent to enter the interior of the building through the air vents. The motorized shade 10 remains in the bottom-most position when the solar radiation intensity signal detected by the small weather station 16 is below a set value. The angle of the first-stage guide plate 19 is adjusted to be parallel to the ground, so that the capability of the air with lower temperature on the side surface of the heat collection wall entering the air channel 5 is enhanced to the maximum degree. Meanwhile, the angle of the second-stage guide plate 17 is automatically adjusted to a design angle according to a wind direction signal detected by the weather station 16 so as to guide natural wind to enter the air channel 5 through the first-stage guide plate 19 to the maximum degree, the surface temperature of the heat absorbing plate is reduced so as to be beneficial to the indoor heat transfer to the outdoor, and meanwhile, the natural wind enters the interior of the building through the first ventilation opening 11 and the second ventilation opening 13, so that the ventilation capacity of the room is enhanced, the indoor temperature is reduced, and the comfort of a human body is improved.

In practical application, in rainy days with weak sunlight, the outdoor air temperature is lower than that in indoor, the electric air volume adjusting valves 3 and 9 are closed, and the electric air volume adjusting valves 12 and 14 are opened, so that rainwater is prevented from entering the indoor. The motorized shade 10 remains in the bottom-most position when the solar radiation intensity signal detected by the small weather station 16 is below a set value. When the rainfall signal detected by the small weather station 16 is higher than the set value, the blade angle of the first-stage guide plate 19 is adjusted to the set value, and rainwater is prevented from entering the air channel 5 while ventilation is performed. Meanwhile, the angle of the second-stage guide plate 17 is automatically adjusted to a design angle according to a wind direction signal detected by the weather station 16 so as to guide natural wind to enter the air channel through the first-stage guide plate 19 to the maximum degree, the surface temperature of the heat absorbing plate is reduced, indoor heat is favorably transmitted to the outdoor, and meanwhile, the natural wind enters the interior of the building through the first ventilation opening 11 and the second ventilation opening 13, so that the ventilation capacity of the room is enhanced, the indoor temperature is reduced, and the comfort of a human body is improved.

The electric sunshade curtain is arranged outside the heat collection wall system, can automatically run to the middle part of the glass cover plate according to solar radiation intensity signals, absorbs solar radiation heat through the upper heat absorption plate, heats the air temperature at the upper part of the air channel, forms a chimney effect by utilizing the temperature difference between the upper part and the lower part in the air channel to the maximum extent, strengthens the ventilation, air exchange and temperature reduction capability of indoor air through the ventilation opening of the heat collection wall system, and reduces the obtained solar radiation heat to enter the indoor space through the heat convection of the ventilation opening and the heat conduction of the heat absorption plate to the maximum extent, thereby improving the thermal comfort of indoor human bodies. In comparison, the conventional heat collecting wall system only adopts a measure of fully shading the sun by arranging a sun shading curtain in the air channel in summer, so that the absorbed solar radiant heat is prevented from entering the room, and meanwhile, the chimney effect cannot be utilized to induce the indoor natural ventilation.

The automatic air deflector is arranged on the side surface of the air channel of the heat collection wall system, the automatic air deflector is also arranged outside the system, outdoor natural wind can be introduced to the maximum degree to enter the building through the heat collection wall system in rainy days, and the heat exchange between the heat collection wall system and the outdoor environment is enhanced, so that the indoor air temperature is reduced to the maximum degree, and the thermal comfort of a human body is improved. Compared with the prior art, the traditional heat collecting wall system cannot achieve the purpose of inducing indoor ventilation and cooling in the weather without solar radiation illumination, particularly in rainy days, and is more unfavorable for the transmission of indoor heat to the outdoor environment due to the fact that the wall body of the heat collecting wall system is smaller in heat transfer coefficient compared with the traditional wall body, and the comfort of an indoor human body is greatly reduced.

The invention realizes the purposes of inducing indoor ventilation by utilizing solar radiant heat, ventilating and cooling by utilizing outdoor natural cold air, strengthening heat exchange between a heat collection wall system and outdoor air in rainy days, utilizing a natural air cold source to the maximum extent, overcoming the defect that the traditional heat collection wall cannot be effectively used in summer and even generates unfavorable application in the process of transmitting indoor heat to the outdoor, and achieving the purpose of efficiently utilizing the natural air cold source and solar energy.

The above-mentioned embodiments are only preferred embodiments of the present invention, and all equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the claims of the present invention.
