摘　　要：以徽州传统民居为研究对象,分析夏季通过传统民居围护结构的传热量,并建立防热构件热平衡模型,进行防热设计策略的效果分析。结果表明:在夏季,徽州传统民居白天表现为得热,夜晚表现为失热;外墙防热设计策略的防热效果为反射>外遮阳>蓄热>对流换热>长波辐射;屋顶防热设计策略的防热效果反射>蓄热>对流换热>长波辐射;天井防热设计策略的防热效果为自然通风>水体蒸发;外墙的防热效果贡献率最大,天井能起到较好的辅助防热效果;同时,外墙和屋顶反射的防热效果贡献率最大,天井具有的水体蒸发与自然通风特性可以进一步提高民居的防热效果。Taking Huizhou traditional residence as the research object,this article analyzes the heat transfer capacity of traditional residence’s envelopes in summer,and establishes the heat balance model of heat protection components to analyze the effect of heat protection design strategy.The results show that:in the summer,the traditional residences in Huizhou are characterized by heat gain during the day and heat loss at night;the heat protection effect of the external wall heat protection design strategy:reflection>external shading>heat storage>convective heat transfer>long wave radiation;the heat protection effect of roof heat protection design strategy:reflection>heat storage>convective heat transfer>long wave radiation;the heat protection effect of the patio heat protection design strategy:natural ventilation>water evaporation;the external wall has the largest contribution in heat protection effect,and the patio has a good auxiliary heat protection role,at the same time,the external wall and roof reflection have the highest contribution rate in heat protection effect,and the water evaporation and natural ventilation characteristics of the patio can further improve the heat protection effect of the residence.
