寒冷地区半透明光伏窗热工参数限值研究
Study on thermal parameters of semi-transparent photovoltaic window in cold regions of China
摘要
Abstract
Due to the selection of solar radiation spectrum by solar cells in semi-transparent photovoltaic windows,the energy consumption,indoor daylight and thermal environment of photovoltaic window buildings are different with clear glass window buildings.When semi-transparent photovoltaic windows are applied to building,specific design values for thermal parameters are required for reference,but there is a lack of basis.Therefore,this paper took an office building in Taiyuan as an example,established a reference building model and a design building model,and explored the influence of the Heat Transfer Coefficient(U-value)and Solar Heat Gain Coefficient(SHGC)on the energy consumption of semi-transparent photovoltaic window buildings.The recommended range of U-value and SHGC value of photovoltaic window is obtained by the method of trade-off judgment.The results show that smaller U-value and larger SHGC value are more beneficial to energy saving when photovoltaic windows are used in Taiyuan.When the window-wall ratio of photovoltaic window building is greater than 0.60 and the transmittance is equal to 0.46,the maximum U-value limit is 1.9 times the existing energy-saving standard limit.By comparing the recommended range of SHGC value with different window wall ratio,the lower limit of SHGC decreases by 25%.关键词
