【摘要】 通过在环境实验室内搭设实体建筑物，模拟夏热冬冷地区夏季、冬季的太阳辐射和室内外温度环境，测试不同太阳辐射强度下建筑外墙温度场和热流密度的变化情况，分析夏热冬冷地区太阳辐射通过外墙热传导对建筑能耗的影响。结果表明：随着太阳辐射强度的增加，建筑外墙外表面、中心和内表面温度随之升高，太阳辐射通过建筑外墙的温度场进行室内外热能传递，进而影响其建筑能耗。在夏季，太阳辐射是决定建筑外墙冷负荷的主要原因，外墙热流密度随太阳辐射强度增大而增加，导致建筑冷负荷增大，空调能耗增加；在冬季，外墙热流密度随太阳辐射强度增大而下降，导致建筑热负荷减小，采暖能耗降低。更多还原

【Abstract】 A physical building was set up in the environmental test room to simulate the solar radiation and indoor/outdoor temperature environment in hot summer and cold winter areas. The changes of the temperature field and heat flux of exterior wall under different solar radiation intensities were tested to analyze the impact of solar radiation through the exterior wall on building energy consumption in hot summer and cold winter areas. Results show that with the increase of the solar radiation intensity,the temperature of the external,center and internal surface of the building exterior wall increase. The solar radiation affects the indoor and outdoor heat transfer through affecting the temperature field of the external wall of the building,thus affecting its building energy consumption. In summer,solar radiation is the main factor that determines the cooling load of exterior wall. The heat flux in-creases with the solar radiation intensity,resulting in an increase of cooling load and an increase in the energy consumption of the building. In winter,the heat flux of the exterior wall decreases with the solar radiation intensity,resulting in a reduction of heat load and a reduction in energy consumption of the building.更多还原
