摘　　要：提出了组合式相变房间的方法,即在不同朝向的围护结构上布置不同相变温度的相变材料,分别用于在冬季和夏季通过发生相变改善室内热环境.搭建了组合式相变房间试验装置,对其进行了夏季工况的试验研究,测量并计算了相变房间的室内空气温度以及不同朝向围护结构的对流换热及辐射换热的热流密度,并与普通房间进行了对比分析.结果显示这种新型相变房间能有效改善夏季室内热环境,其围护结构换热性能也与普通房间存在一定的差异.This paper presents an idea about combined phase change material room, which lays two different kinds of phase change material （PCM） in building envelopes of different orientation. The two PCMs occur phase transition separately in winter and summer. The experimental rooms of combined phase change material and ordinary material are built and the experiment is done for summer condition. Measurement and calculation are done to indoor air temperature and convection and radiation heat fluxes of the combined PCM room. Comparison is done with ordinary room. Results show that this new type of room can effectively improve indoor thermal environment during summer, thermal performance of the building envelopes also shows some differences with ordinary room.
