摘　　要：以青海地区居住建筑为研究对象,通过EnergyPlus模拟软件研究了不同传热系数和太阳辐射吸收系数下各朝向墙体内外表面温度的变化规律,并对其热流密度进行对比分析。结果表明:增大太阳辐射吸收系数能有效提高墙体外表面平均温度,减小传热系数能有效提高墙体内表面平均温度。太阳辐射吸收系数对南墙平均热流密度影响最大,其次为屋面,北墙最小;传热系数对北墙平均热流密度影响最大,其次为屋面,南墙最小。A residential building in Qinghai is taken as the research object,the variation law of the inner and outer surface temperature of the wall under different heat transfer coefficients and solar radiation absorption coefficients was studied by EnergyPlus simulation software,and the heat flux density was compared and analyzed.The results show that increase the solar radiation absorption coefficient can effectively improve the average temperature of the outer surface of the wall,and reduce the heat transfer coefficient can effectively improve the average temperature of the inner surface of the wall.The solar radiation absorption coefficient has the greatest influence on the average heat flux density of the south wall,followed by the roof,and the smallest is the north wall.The heat transfer coefficient has the greatest influence on the average heat flux density of the north wall,followed by the roof,and the smallest is the south wall.
