摘　　要：建筑内墙能耗是建筑能耗组成中所不能忽视的一部分,内墙之于建筑能耗的影响,除了在采暖空调时间内传到邻室的热(冷)量外还包括蓄存在墙内的热(冷)量。运用数值模拟的方式,分析了在间歇采暖空调条件下,墙体蓄热随各因素的变化规律。最终得出结论,当采暖空调间歇时间在5小时以内时,建筑内墙的热过程以蓄热为主,对于内墙热工的优化应当考虑减小墙体的蓄热能力。Building interior wall energy consumption is the part of building energy consumption which cannot be ignored, and the impact of the interior wall on building energy consumption in heating and air conditioning time includes the heat （cold） storage in wall besides the heat transfer to the adjacent room. In this paper, the author analyses the interior wail energy storage changes with various factors in the condition of intermittent heating and air conditioning by the method of numerical simulation. Eventually come to the conclusion that if the intermittent time of heating and air conditioning is in 5 hours, the main heat transfer process of building interior wall is heat storage, therefore, the optimization of thermal interior wall should focus on reducing the heat storage capacity.
