Problems solved by technology

[0003] The traditional Trombo wall is mainly composed of a transparent cover, a heat collecting wall and an air flow channel. Its main function is to collect heat and heat through the heat collecting wall. It has a single function and is not suitable for subtropical regions. It is only suitable for day and night The temperature difference is large, the winter is long and the annual average temperature is low. At the same time, due to the existence of the heat collecting wall, the traditional Trombe wall is blocked when it is used as a curtain wall, and it is difficult to daylight

Embodiment 1

[0034] Such as figure 2 As shown, when heating is required to adjust the comfortable temperature in the early morning of winter and summer, open the indoor upper vent baffle 5 and the lower vent baffle 7 to open the indoor upper vent 4 and the indoor lower vent 6; at this time, adjust Shutter 2, make the side of the shutter 2 pasted with thin-film battery 11 (CIGS battery) face outward, the shutter is closed, through the curtain wall body 1, while the thin-film battery 11 generates electricity to supply energy, utilize battery heating and CIGS black packaging material 14 The absorbed radiant heat energy heats the air in the air passage 3 . Through thermosiphon action, indoor cold air flows into the runner from the indoor lower vent 7, and after heating up, flows into the room from the indoor upper vent 4 to adjust the temperature. As the temperature rises, the inclination angle of the louver 2 can be adjusted to adjust the power generation and heat collection functions of th...

Embodiment 2

[0036] Such as image 3 As shown, at noon or when the temperature is higher, close the indoor upper vent baffle 5 and the indoor lower vent baffle 7, so that the indoor upper vent 4 and the indoor lower vent 6 are closed. At this time, the shutters 2 are adjusted to make The side of the louver 2 coated with the polyvinyl fluoride selective radiation coating 12 faces outward, and the louver 2 is closed. At this time, the light in the 300-700 band is absorbed by the amorphous silicon thin-film battery forming the curtain wall body 1 for power generation, and most of the remaining solar radiation is reflected by the radiation coating 12 of polyvinyl fluoride, so that the amorphous silicon film of the curtain wall body 1 Silicon cells reduce the amount of solar radiation absorbed while fully generating electricity. The burden on the refrigerators such as air conditioners is alleviated. At the same time, the outdoor vent 8 is opened, and the driving motor 9 is ventilated, which ca...

Embodiment 3

[0038] Such as Figure 4 1. When at night, if the air conditioner is not turned on indoors, open the upper air vent baffle plate 5 and the lower air vent baffle plate 7 in the room to open the upper air vent 4 and the lower air vent 6 indoors, and adjust the shutters 2 to make them coated with polyfluorine. The blades of the ethylene radiation coating 12 face outwards, and utilize its high reflectivity in the whole band and emissivity in the infrared band to strengthen the radiation heat exchange with the outdoor space and reduce the indoor radiation heat exchange. Indoor hot air enters the air channel 3 through the upper vent 5 in the room, and gradually cools down by convective heat exchange with the polyvinyl fluoride coating 12 , and then enters the room through the lower vent 6 in the room to adjust the temperature.

Abstract

The invention belongs to the field of energy saving of buildings and particularly discloses a trombe curtain wall suitable for a subtropical area. The trombe curtain wall suitable for the subtropical area comprises a curtain wall body and a drivable shutter, wherein the curtain wall body is made of a film solar cell module, and the shutter serves as a reflective heat-insulation wall. The curtain wall body and the shutter are arranged in a spaced mode. The interval between the curtain wall body and the shutter is an air flow channel. An upper indoor ventilation opening and a lower indoor ventilation opening are formed in the upper portion and the lower portion of the shutter correspondingly. An upper baffle is arranged in the position of the upper ventilation opening, and a lower baffle is arranged in the position of the lower ventilation opening. An outdoor ventilation opening is formed in the upper portion of the curtain wall body, and a draught fan is installed in the position of the outdoor ventilation opening. The curtain wall has a heat collection function and a solar power generation function and can reduce the heat load; meanwhile, the light transmission and lighting performance are good, and obstruction of the view field is avoided; and the trombe curtain wall suitable for the subtropical area has various functions and is wide in application field.

Description

technical field [0001] The invention belongs to the field of building energy saving and relates to a novel curtain wall for solar power generation and radiation cooling. Background technique [0002] In the existing technology, solar energy, as an ideal and clean renewable energy, has been increasingly valued by countries all over the world. Under the background of advocating green energy conservation, building integrated photovoltaics has developed rapidly in recent years. The advantages of building integrated photovoltaics are in the development of energy-saving buildings Today, it is constantly highlighted that integrating photovoltaic systems into buildings can achieve resource conservation and comprehensive utilization, efficiently utilize natural resources, and reduce environmental loads. [0003] The traditional Trombo wall is mainly composed of a transparent cover, a heat collecting wall and an air flow channel. Its main function is to collect heat and heat through t...
