摘　　要：建筑物墙体热工性能检测是建筑节能工程验收的必要环节,而控温箱-热流计法是近年来提出的较实用的现场检测方法。本文阐述了控温箱-热流计法现场检测围护结构传热系数的方法及基本原理,对检测结果出现数据偏差的原因进行了分析,并提出相应的修正方法,包括建立基准板和引入修正系数;最后通过实例验证该修正方法的可行性,为将来测试数据的修正提供参考依据。The thermal performance test of the building envelope must be carried out during the acceptance of the energy-saving projects. The method depending on thermostat-heat flow meter proposed in recent years has been demonstrated as a practical on-site method. Firstly, both the theoretical basis and operation of the mentioned method to obtain the heat transfer coefficients of building walls are introduced in this paper. Subsequently, the causes of the data deviation are analyzed and the corresponding correction methods, including establishing a benchmark board and introducing the correction factors, are proposed. Finally, the reliability of the proposed correction methods are verified by practical example, which provides references for further corrections.
