摘　　要：分析热流计法、热箱法用于围护结构传热系数现场检测的局限性,据此提出热箱-热流计法。论述热箱-热流计法检测系统的设计。采用热箱-热流计法对某建筑物外墙的传热系数进行了实际检测(测试时间为48 h),与理论计算结果进行比较,相对误差为5.5%。The limitations of heat flowmeter method and hot box method used in field detection of the heat transfer coefficient of building envelope are analyzed, and a hot box-heat flowmeter method is pro- posed thereby. The design of detection system by the hot box-heat flowmeter method is described. The heat transfer coefficient of external wall of a building is de- tected by the hot box-heat flowmeter method for 48 hours. The relative error is 5.5% compared with the theoretical calculation result.
