隧道湿热环境下冷却服相变材料试验研究

为寻找合理冷却服类型及冷却材料,为高温高湿隧道环境中施工人员的生命健康提供保障,分析高温高湿环境对人体生理指标、舒适性的影响及目前主要的降温措施;并根据相关行业卫生标准,对国内外冷却服的发展现状进行调研。最后,对相变材料进行试验分析。认为应对隧道高温高湿环境,应选择相变冷服,并提出相变材料改进方向。

Experimental Study on Phase Change Material of Cooling Clothing Used in Humid-and-Thermal Tunnel Environment

The rational selection of cooling clothing and its material to guarantee the life of workers in tunnel with high temperature and humidity is of great importance. As a result, the influence of high temperature and humidity environment on physiological index and comfort of human is analyzed; and then the developing situation of the cooling clothing in China and other countries is investigated according to related hygienic standards; finally, experiment is carried out for phase change material. The results show that the phase change material cooling clothing is feasible for high temperature and humidity tunnel environment, and some improvement methods for phase change material are put forward.
