Self-cleaning photo-thermal photovoltaic integrated heat-insulation ventilation light-transmitting glass roof

Abstract

The invention discloses a self-cleaning photo-thermal photovoltaic integrated heat-insulation ventilation light-transmitting glass roof. The self-cleaning photo-thermal photovoltaic integrated heat-insulation ventilation light-transmitting glass roof comprises a photovoltaic layer, a photo-thermal layer, a heat-insulation layer and louver vents. The photovoltaic layer absorbs and weakens solar radiation heat entering a room by using a solar thin film battery, the photo-thermal layer further absorbs and weakens the solar radiation heat by using a plurality of groups of heat pipes, the heat-insulation layer uses a thin film made of heat-insulation and light-transmission materials to block the radiation heat entering the room outside an atrium, and the louver vents can adjust the ventilationdirection and area according to the outdoor wind speed and wind direction, so that air flow is accelerated and the heat is brought out of the room. According to the elf-cleaning photo-thermal photovoltaic integrated heat-insulation ventilation light-transmitting glass roof, the photo-thermal photovoltaic integrated glass roof is adopted, so that the solar radiation heat entering the room is reduced, and the energy consumption of an air conditioning system in a building is reduced; and a natural light source is used for lighting, the energy consumption of building lighting is reduced, and the self-cleaning photo-thermal photovoltaic integrated heat-insulation ventilation light-transmitting glass roof conforms to the concept of energy conservation and environmental protection of modern greenbuildings.

Description

technical field [0001] The invention belongs to the field of building energy saving and renewable energy utilization, focusing on the field of solar energy utilization technology and heat insulation and ventilation technology, and specifically a self-cleaning photothermal photovoltaic integrated heat insulation and ventilation transparent glass roof. Background technique [0002] In some large buildings such as shopping malls and gymnasiums, special glass and other light-transmitting materials are often used to build roofs due to aesthetics and lighting reasons. In hot weather in summer, the solar radiation is strong, and the glass roof will increase the internal temperature of the building due to the greenhouse effect, increasing the energy consumption of the building. Existing glass roofs generally reflect and scatter solar radiation by adding sunshade devices on the outer surface, adding photovoltaic panels to absorb solar radiation, arranging sunshade devices inside to b...
