为了研究自然通风对轻质墙体热湿传递的影响,设计了一种通风型太阳能光伏多层外墙结构,通过测试房和对比房的对比实验,得出以下结论:光伏组件的遮挡和空气层的存在能减小墙体的得热量,从而减小空调负荷;开启光伏组件背面通风流道,能使墙体更快地干燥,降低墙体内的相对湿度,减小墙体内的湿积累,并可为墙体机械通风时空气层排湿风机的设计提供实验依据。
In order to study the influence of natural ventilation on the heat and moisture transfer of lightweight wall, a ventilated solar PV multilayer exterior wall structure was designed. Through the comparative experiments of the test room and the comparison room, the following conclusions are drawn: the shielding of the PV module and the air The existence of the layer can reduce the heat gain of the wall, so as to reduce the air conditioning load. Opening the ventilation channel on the back of the PV module enables the wall to dry faster, reducing the relative humidity in the wall and reducing the humidity in the wall Accumulation, and can provide the experimental basis for the design of the air layer desiccant fan when the wall is mechanically ventilated.
