摘要
为了评价不同类型冷却服的冷却性能,采用可行走出汗暖体假人"华特"对3件不同类型的冷却背心进行冷却性能测试.3件冷却背心均不同程度地降低了暖体假人的皮肤温度,液态相变材料冷却背心使假人的皮肤温度下降最多,致冷时间最长.而微胶囊相变材料冷却背心使假人的皮肤温度下降最少,致冷时间最短.液体冷却背心的致冷作用则介于二者之间.实验证明3种冷却背心均有明显的致冷效果,但是在穿着舒适性方面它们都存在一定的不足.
To evaluate the cooling performance of different types of cooling garments, three different cooling garments are tested by using movable sweating thermal manikin ＂Walter＂ in temperature cabin. The test results indicate that all of the three cooling garments evidently lower the skin temperature of the thermal manikin. The liquid phase change material cooling garment took away the most heat, and its cooling time is the longest. The microcapsule phase change material cooling garment took away the less heat, and its cooling time is the shortest. The cooling performance of the liquid cooling garment is middling. In conclusion, although all of the three cooling garments evidently removed the heat from the thermal manikin, there are some disadvantages on comfort.
