摘　　要：夏热冬冷地区的住宅建筑常采用间断供暖模式,本文采用数值模拟的方法对其房间能耗特征进行研究。结果表明,供暖持续时间与保温层位置对能耗影响较大。供暖持续时间越短,房间单位时间能耗越大。外墙采用外保温时的能耗高于内保温。In hot summer and cold winter zone, intermittent heating is usually used for residential buildings in winter. In this paper, numerical simulations have been carried out for analyzing the characteristics of energy consumption. The results show that the lasted heating time and location of thermal insulation layer all have serious impacts on heating energy consumption. The shorter the lasted heating time, the larger the energy consumption in unit time. The heating energy consumption of exterior wall external thermal insulation is higher than internal thermal insulation.
