On one hand, the structure can realize the integrated design of the solar photovoltaic panel 108 and the air heat collector to form the solar photovoltaic photo-thermal heat collector, so that the problem that the installation space or the installation area of the independent solar photovoltaic panel is occupied when the common air heat collector is installed on the side vertical surface 602 of the building is solved, and the space utilization rate is improved; on the other hand, the solar photovoltaic panel 108 can convert 15% to 20% of absorbed solar energy into electric energy, and the integrated design can fully utilize the energy left after the electric energy is generated to heat the air, so that the heat utilization rate is improved, the heat dissipation of the solar photovoltaic panel 108 is facilitated, and the photoelectric conversion efficiency is improved. Fig. 4 and 5 show the power generation and heat collection of the collector 100 in a certain day of the weather in the winter of beijing. As can be seen from fig. 4, although the outdoor temperature is substantially maintained at about 3 ℃ during the day, the solar radiation intensity is changed, specifically, the trend of the air temperature at the air outlet 106 of the heat collector 100 is substantially consistent with the solar radiation intensity when the temperature is low in the morning and the evening and reaches the maximum in the noon, the outlet air temperature is also high up to about 35 ℃ during the time period when the solar radiation intensity is high, and the outlet air temperature can be maintained at more than 18 ℃ during the time period from 10 o 'clock to 16 o' clock (i.e., from ten o 'clock to four o' clock in the afternoon), which substantially meets the winter heating requirement. As can be seen from fig. 5, the variation trend of the solar generated power and the solar heat generation power is also substantially consistent with the variation trend of the solar radiation intensity shown in fig. 4, the solar generated power can reach up to about 350w, the solar generated power can be substantially maintained above 200w during the period from 10 to 16 points, the solar heat generation power can be close to 800w at most, and the solar heat generation power can be substantially maintained above 400w during the period from 10 to 16 points.

Specifically, according to different requirements for electric energy and heat energy, the solar photovoltaic panel 108 may be covered on the entire outer side wall of the heat collection cavity 102 away from the building side vertical surface 602, or the solar photovoltaic panel 108 may be covered on only a portion of the outer side wall of the heat collection cavity 102 away from the building side vertical surface 602, and a common solar heat collection panel may be covered on another portion of the outer side wall of the heat collection cavity 102 away from the building side vertical surface 602.

Further, as shown in fig. 2, the base plate 110 includes a plate body 112 and a plurality of partitions 114. The panel body 112 provides a secure connection of the collector 100 to a surface to be installed (e.g., a building side facade 602, such as that shown in fig. 1, which may be mounted to a wall surface below a window 604). The side of the plate body 112 away from the building object side vertical surface 602 is provided with a plurality of parallel partitions 114 at intervals, and one end of each partition 114 away from the plate body 112 is in contact with the heat conducting connection layer 116, so as to divide the heat collecting cavity 102 into a plurality of parallel air flow channels, which not only helps to guide the air flow and reduce the energy loss caused by air flow disturbance, but also can use the partition 114 as a fin to improve the air flow heat exchange efficiency.

Specifically, the cross section of the partition 114 may be rectangular as shown in fig. 2, or may be triangular, trapezoidal, or other different shapes. It is conceivable that the air flow passages with corresponding shapes can be formed by specifically designing the distribution shapes of the partitions 114 on the plate body 112, for example, as shown in fig. 3, the adjacent partitions 114 are staggered to form S-shaped air flow passages, and the length of the air flow passages can be extended while keeping the height of the heat collector 100 inconvenient, so that the air flow can sufficiently absorb heat, and the air flow directions on both sides of the same partition 114 are opposite; for another example, the partitions 114 may be divided into several groups, and one group of the partitions 114 forms an S-shaped airflow channel to control the length of the airflow channel and ensure the heat exchange efficiency.

The blower blows air in a direction away from the purifying device 200 through the air outlet 204, and provides power for air circulation, so that air to be heated is sucked into the heat collecting cavity 102, and then the heated air is blown into the room, thereby realizing hot air heating. Specifically, the air supply amount can be adjusted by controlling the rotation speed of the fan.

Further, as shown in fig. 2, the heat collector 100 further includes an indoor air return opening 118 communicating with the heat collecting cavity 102 to recover indoor air and return the air to the room after heat exchange, thereby achieving indoor air circulation and temperature regulation.

Specifically, when the first valve body 502 and the second valve body 504 are opened and the third valve body 506 is closed, independent fresh air supply can be realized; when the second valve body 504 and the third valve body 506 are opened and the first valve body 502 is closed, separate indoor air circulation and temperature regulation can be realized; when the first valve body 502, the second valve body 504, and the third valve body 506 are simultaneously opened, fresh air can be supplied while the indoor air circulation and temperature regulation are achieved. For example, the first valve body 502, the second valve body 504, and the third valve body 506 may be valve bodies capable of accurately adjusting flow, such as a regulating valve, a V-valve, an angle valve, a needle valve, a butterfly valve, and a diaphragm valve, to control the air supply amount, or valve bodies functioning as switches, such as a ball valve and a gate valve.

Alternatively, as shown in fig. 1, the controller 508 is disposed in the space above the ceiling 606 (the connection line between the controller 508 and other structures is not shown), it is understood that the controller 508 may be disposed in other positions, such as the inner wall surface, or a special electrical control box is provided, which are all embodiments of the present invention.

Specifically, by the suction action of the negative pressure fan 400, the outdoor fresh air enters the heat collector 100 through the first valve body 502, and when flowing through the heat collection cavity 102, the outdoor fresh air can perform radiation heat exchange with the sky through the solar photovoltaic panel 108, so that the heat energy of the outdoor fresh air is continuously transmitted to the external environment in a radiation manner, and the air temperature in the heat collection cavity 102 can be reduced by 3 ℃ to 4 ℃. The cooled air flows through the purification device 200 and then enters the room through the air supply outlet 204, so that the cooling capacity can be provided for the room, the heat collector 100 can perform a refrigeration function in summer, and the use efficiency is improved. At the moment, the cooling is realized through the radiation heat exchange with the sky, so when the outdoor is dry and the weather is clear, the efficiency of the radiation heat exchange is higher, and the cooling effect is better. Fig. 6 shows the curve of outdoor fresh air cooling performed during 20 o 'clock to 24 o' clock of beijing summer (i.e. eight o 'clock to twelve o' clock of night) in the night cooling mode, and it can be seen from fig. 6 that, when the night cooling mode is operated, the air temperature at the air outlet 106 of the heat collector 100 can be reduced by 3 ℃ to 4 ℃ compared with the outdoor temperature, so as to provide proper cooling capacity indoors. It is understood that when the indoor return air opening 118 and the third valve body 506 are not provided, the controller 508 may be configured to control the first valve body 502 and the second valve body 504 to open.

Specifically, the negative pressure fan 400 located at the air supply outlet 204 starts to work, external fresh air is sucked into the heat collector 100 through the first valve 502, and when the fresh air passes through the heat collecting cavity 102 of the heat collector 100, heat generated by the solar photovoltaic panel 108 due to solar energy absorption can be taken away by the fresh air, so that the fresh air is heated. The heated fresh air enters the purification device 200 through the air supply pipeline 300, after coarse effect, medium effect and high-efficiency three-stage filtration, PM2.5 in the fresh air can be filtered by more than 95%, and the hot air after purification and dust removal directly enters the room through the air supply outlet 204 for heating.
