【摘要】 双层窗及多层窗在传热、渗透同时存在时的综合能耗并不等于它们单独存在时的能耗之和。文中介绍了所研制的窗的综合能耗测试装置的构造、原理及功能。它是测试、研究窗综合能耗的关键设备，也是测试其它建筑围护构件热工性能的主要设备。更多还原

【Abstract】 The overall energy consumption of double window and multiple window because of conducting heat and infiltrating heat, is not equal to the single sum of energy consumption only by conducting heat and by infiltrating heat respectively The construction, principle and function of the measuring units, which test the overall energy consumption were introduced It is the key equipment testing and researching the overall energy consumption of window, and also the main equipment testing the thermodynamic property of other enclosure更多还原
