Description

technical field [0001] The invention relates to a sunshade technology, in particular to a photovoltaic sunshade device with a fresh air ventilation function. Background technique [0002] In today's global warming, the energy consumption of air conditioning in summer accounts for an important part of building energy consumption. In hot summer, the heat directly entering the room through the solar radiation through the windows is the main cause of indoor overheating or a serious increase in the cooling load of the air conditioner. Therefore, reasonable sunshade is the most effective energy-saving measure for heat insulation in summer, and it is also the most immediate energy-saving method. Architectural shading reflects and absorbs most of the solar energy, prevents solar radiant heat from directly entering the indoor space, helps prevent the rise and fluctuation of room temperature, and plays an important role in improving indoor thermal comfort and reducing air-conditioning...

Problems solved by technology

However, these two sunshades only use photovoltaic power generation and are not combined with the building's fresh air system

[0005] It can be seen that although the above schemes use photovoltaic panels to achieve the functions of sunshade and power generation to a certain extent, they have not effectively combined sunshade and indoor ventilation. Does not use indoor air to cool photovoltaic panels, reduce photovoltaic cell temperature, and improve power generation efficiency
