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 Energy-Plus 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 coeffi-cient 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.
