detailed description

As shown in Figure 1, a louver heat storage wall system in a heat collection system coupled with a louver heat storage wall and a solar kang includes a heat collection heat storage wall 3 and a transparent glass cover plate 1 parallel to each other, and a heat collection heat storage wall 3 The space between it and the transparent glass cover plate 1 is an air flow channel 4, and the inside surface of the transparent glass cover plate 1 is provided with a venetian blind 2, and one side of the blade of the venetian blind 2 is coated with a selective absorption coating, and the other side is a Selective radiation surface; the upper and lower parts of the heat collecting and storage wall 3 are provided with vents 5 and 6 respectively, and baffles 7 and 8 are respectively installed at the vents; the venetian blinds are connected with an intelligent adjustment device 9 for the angle of louver blades.

As shown in Figure 2, the solar kang system in a louver heat storage wall and solar kang coupling heat collection system includes a hot water storage tank 11 connected to a solar flat panel heat collector 10 at one end, and connected to a water supply main pipe 13 at the other end, and the water supply main pipe 13 and the return water main pipe 15 are equipped with a circulation pump 14, and double "return" type laying heat pipes are used in the kang. The hot water storage tank 11 is connected, and the hot water storage tank 11 is connected with the flat plate heat collector 10 . An intelligent temperature controller 21 is installed on the kang body 18 to be connected with the circulating pump 14 .

During the daytime in winter, the side of the blinds coated with selective absorbing coating faces outwards to absorb the solar radiation energy passing through the transparent glass cover, thereby heating the air in the air flow channel 4, and the cold air in the room flows in from the vent 5 In the air flow channel 4, it rises through the heat rainbow effect and is continuously heated into hot air, and then flows into the room through the vent 6 for heating. The temperature has been greatly increased. At the same time, the solar kang system stores the heat collected by the solar panel heat collector 10 in the heat storage tank 11, and then uses the heat of the heat storage tank 11 to heat the pit 18 by the forced circulation of the circulation pump 14, and stores the solar energy in the pit. In 18, through the pit 18, the heat dissipation of the room is used to improve the indoor thermal environment and the sleeping thermal environment at night. The intelligent temperature controller 21 on the kang body is connected with the circulating pump 14. After the temperature of the kang body exceeds the limit value, the pump 14 stops working, which ensures that the kang body can provide a comfortable sleep temperature.

At night in winter, close all the heat insulation covers 7 and 8, so that the vents are all in a closed state, and the side of the blades coated with selective radiation coating on the venetian blind 2 faces outwards to reduce the heat lost by its outward radiation, and at the same time during the day The heat stored in the heat-collecting heat-storage wall 3 is slowly introduced into the room for heating through heat conduction. On the other hand, the heat stored in the solar kang during the day heats the room and improves sleeping comfort through heat conduction.

When it is cloudy, the auxiliary heating coil 12 is used to heat the heat storage tank 11 to provide heating for the solar kang and the room.

During the daytime in summer, one side of the blades coated with selective radiation coating on the venetian blind 2 faces outwards, and at the same time, the angle of the louvers is adjusted by the louver angle intelligent adjustment device, so that most of the solar radiation energy projected on the surface during the day is reflected back , to reduce the absorbed solar radiation. At night in summer, one side of the blades coated with the selective radiation coating on the venetian blind 2 faces outwards to reduce radiation heat exchange with the surrounding environment. On the other hand, the solar kang can close the water inlet 16 and the water outlet 17 of the kang body to provide hot water for life instead.
