摘　　要：利用热箱法对我国夏季不同气候区以相变墙为南外墙的房间的热响应进行实验研究。分析相变房间在不同气候区使用时的优缺点,并利用"预计平均热感觉指数(PMV)"和"预计不满意者的百分数(PPD)"两个指标做出相应评价。结果表明:像北京这样的综合平均温度与相变温度比较接近,且在综合温度下昼夜温差高于27℃的气候条件,将相变材料置于墙体内孔时,其潜热利用率达到72.2%;而且室内舒适度好,PMV与PPD值分别为0.63%与13.33%。Using the hot box method experimental study the thermal response performance of the room with phase change exterior wall and it＇ s merits and demerits in different climatic region in summer are analyzed. ＂Pre- dicted mean vote （PMV） ＂ and ＂predicted percentage of dissatisfied （PPD） ＂ are used to evaluate the indoor ther- mal comfort. Results show that for place such as Beijing where the climatic integrated average temperature is close to phase change temperature and the temperature difference between day and night is higher than 27 ℃, the latent heat utilization ratio can reach up to 72. 2%, when phase change materials （PCMs） are placed inside the wall block hole. In this case, the indoor thermal comfort is quite satisfactory with PMV and PPD to be 0. 63% and 13.33%, respectively.
