摘　　要：通过对湿热地区常用墙体构造传热系数测试温度对比研究,得到如下结论:传热系数测试的冷热箱温差越大,结果准确度越高。适合湿热地区墙体传热系数实验室测试的温度范围为:冷箱温度介于0℃~10℃,冷热箱温差不小于25℃,最好超过30℃。Through a comparative study on the temperature of the thermal transmittance test of wall structures commonly used in the hot-humid region,the following conclusions were drawn:the greater the temperature difference between the cold and hot boxes in the heat transfer coefficient test,the higher the accuracy of the results.The temperature range suitable for laboratory testing of the wall thermal transmittance in the hot-humid region was:the temperature of the cold box was between 0 and 10℃,and the temperature difference between the cold and hot box was not less than 25℃,preferably more than 30℃.
