摘要
通过建立基于焓法相变墙板的传热模型,研究了其传热特性,分析了影响相变墙板传热性能的因素,选取出了适合于重庆地区的相变墙板,研究了重庆的相变墙房间和普通房间的传热特性,对比分析了夏季和冬季相变墙房间和普通房间的温度情况并经实测验证。结合削峰填谷政策做了经济性分析。结果表明相变墙房间不仅节省能源,能提供舒适的环境。而且投资回收期仅十四个月。
Based on the enthalpy model of phase change material wallboard room, the factors influencing the heat transfer performance of the wallboard were analyzed and the one suitable for Chongqing was choosen, the heat transfer performance of a phase change material wallboard room and a common room in Chongqing were simulated. And the indoor air temperatures of the phase change material wallboard room and of the common room in summer and winter were analyzed and the simulation was validated by experiments. The economy analysis was done by counting the load shifting policy. The results show that such a room is not only energy efficient, thermal comfort, but also is of short feedback period （only 14 months）.
