【 摘 要 】

With the increasing energy consumption, the status of building energy conservation is paid more and more attention. So how to reduce the energy consumption of envelope becomes a hot spot. Self-insulation wall behaves greatly in energy saving, and this paper proposes a self-insulation wall which is filled Expanding Polystyrene(EPS) into the cavities of the sintered shale bricks with different ration. Besides, the condition of intermittent operation of air conditioner in winter is simulated. The results showed that temperature of the wall increased significantly after filling the EPS, and the wall had a good thermal insulation performance. The thermal insulation wall with 50% EPS is recommended, no matter from the aspect of the economy or of thermal physics. Moreover, intermittent operation which is 1 hour interval and 1 hour working was the idealist mode, because the wall performed the best capacity of insulation under this condition.
