Problems solved by technology

In summer, the air temperature of indoor exhaust air is low, and it will be a waste of energy to discharge it directly to the outside; in winter, the air temperature of fresh air is low, and the energy consumption for processing fresh air is high. Reducing building energy consumption has also become a challenge

Abstract

The invention discloses a double-sided photovoltaic window ventilation system. A double-sided photovoltaic panel is installed on the outer surface of the building outer wall, a reflecting film is installed on the inner surface of the building outer wall, an air channel is reserved in the middle of the reflecting film, and ventilation openings are reserved in the upper portion and the lower portion of the double-sided photovoltaic panel to communicate outdoor air with the air channel, ventilation openings are formed above and below the reflecting film, the air channel is in communication with an air processing system composed of the evaporator, a condenser, a compressor and a throttling valve through the upper ventilation opening, and indoor air is in communication with the air channel through the lower ventilation opening. Through the optimized double-sided photovoltaic window ventilation system, indoor and outdoor ventilation is enhanced, due to the characteristic that the front face and the back face of the double-sided photovoltaic panel can generate power, the power generation efficiency of the back of the double-sided photovoltaic panel is improved through reflection of solar radiation by the reflecting film, meanwhile, the double-sided photovoltaic panel can be cooled when air flows through the back of the double-sided photovoltaic panel, and the efficiency of the photovoltaic panel is further improved.

Description

technical field [0001] The invention relates to the field of photovoltaic cells, in particular, a double-sided photovoltaic window ventilation system is designed. Background technique [0002] my country is rich in solar energy resources. As an effective way to utilize solar energy, photovoltaic power generation has attracted widespread attention from the society because of its clean and convenient features. Among them, double-sided photovoltaics, as a promising technology, have been widely recognized in domestic and foreign markets because of their high power generation efficiency, accounting for about 60% of the market share in recent years. Different from ordinary single-sided crystalline silicon cells used in traditional single-sided photovoltaics, double-sided photovoltaics use unique double-sided photovoltaic cells, and use transparent glass instead of traditional backplanes, both sides can generate electricity (the back side absorbs the sun reflected by the environmen...
