组合式相变房间围护结构冬季换热性能研究

Research on the winter heat exchange performance of envelops of combined phase change material rooms

搭建了组合式相变围护结构和普通围护结构的实验房间,测试并计算了两个房间的室内空气温度、不同朝向围护结构的热流密度。通过对比分析可知,组合式相变房间能有效改善冬季室内热环境,其围护结构换热性能也与普通房间存在一定的差异。

In this paper, two experimental rooms of combined phase change material and ordinary material are built. The indoor air temperature the two rooms and the heat fluxes of envelops in different directions are mea-sured and calculated. The results of the comparison show that the combined phase change material room can ef-fectively improve the indoor thermal environment during the winter, and the performance of the building en-velopes thermal also differs from that of the ordinary room.
