摘　　要：以河北省保定市某装配式被动房为研究对象,采用热流计法对其东、西两侧围护结构主体部位的传热系数进行现场测试。基于测试结果,利用DeST能耗模拟软件模拟该建筑理论计算和实测传热系数下的全年能耗,得出理论计算与实测条件下利用传热系数计算的能耗偏差。结果表明该装配式被动房东、西两侧围护结构主体部位的实测传热系数相比.于理论计算值分别偏高偏差为103%。以期通过传热系数现场测试过程与能耗误差值的范围为今后进一步研究装配式被动建筑提供参考。Taking an assembled passive house in Baoding City,Hebei Province,as the research object,the heat transfer coefficient of the main part of the east and west sides of the enclosure structure was tested on-site using the heat flow meter method.Based on the test results,the DeST energy consumption simulation software was used to simulate the annual energy consumption of the building under the theoretical and measured heat transfer coefficients,and the deviation of the energy consumption using the heat transfer coefficients under the theoretical and measured conditions was obtained.The results show that the measured heat transfer coefficients of the main part of the east and west sides of the envelope of the assembled passive house are higher than the theoretically calculated values by 8.1%and 8.2%,respectively.The deviation of annual cooling energy consumption between theoretical calculation and measured heat transfer coefficient is 6.9%,the deviation of annual heating energy consumption is 11.1%,and the deviation of annual total air-conditioning energy consumption is 10.3%.In order to provide a reference for further research on assembled passive buildings through the process of heat transfer coefficient field test and the range of error values of energy consumption.
