摘要
既有建筑节能改造是降低建筑能耗的一个重要途径.对既有建筑进行改造,必须了解其围护结构的热工性能和能耗状况,才能设计出经济合理的节能改造方案.现场检测正是获取这些数据的一种手段.本文对既有建筑围护结构的热工性能基础数据测定的一种方法——双面热流计法测定围护结构传热系数的方法作一介绍,为既有建筑节能改造基础数据的收集提供一种行之有效的方法.
It is an important approach to reconstruct the energy-saving heating system of existing building in reducing energy consumption. It is essential to find out the thermal property of building envelope in order to design economical and reasonable scheme of energy-saving reconstruction when existing buildings are reconstructed. Field testing is a method of receiving the thermal property of building envelope. The paper introduces a method -double-heat flow meter, Which provide a feasible method for collecting basal data of energy-saving reconstruction of existing buildings.
