摘　　要：为了研究应用于夏热冬暖地区的双层外呼吸式光伏种植幕墙的热工性能,本研究以海口地区为例,利用建模软件ANSYS19.0中的FLUENT模块建立了双层幕墙的标准模型,并对双层外呼吸式光伏种植幕墙的内部气温和综合传热系数进行了模拟,同时也对其在夏热冬暖型地区时的热工性能展开了相关研究,通过分析可知:其综合传热系数为1.06 W/(m2·K),相比于《公共建筑节能设计标准》(GB 50189—2015)中的规定[海口地区最不利条件下的综合传热系数要求为2.0 W/(m2·K)],其综合传热系数要小很多,因此可满足应用要求.由于其具有良好的热工性能,故可广泛地应用于实际工程.In order to analyze the thermal performance of the external respiration DSF(Double Skin Facade)which integrated with biological shading technology formed by vertical planting and photovoltaic(pv)membrane,in our report,Haikou was used as an example,the standard model of DSF based on the ANSYS19. 0 Fluent software was established,its internal temperature and comprehensive heat transfer coefficient were simulated,and its thermal performance in hot summer and warm winter areas were analyzed. The results indicated that the comprehensive heat transfer coefficient of photovoltaic planting DSF is 1. 06 W/(m2·K),which is much less than the required 2. 0 W/(m2·K)of Haikou area under the most unfavorable conditions according to the Design Standard for Energy Efficiency of Public Buildings(GB 50189-2015). Because of its good thermal performance,it can be widely used in practical engineering.
