Thermal Requirement Analysis of Phase Change Protective Clothing in Low Temperature Environment

摘要

In low temperature environment, the lack of a proper thermal protection can cause human body frostbiteapp: addword: frostbite, or even cause death. In this paper, the computational method of theoretical relationship between the phase change materials content in protective clothing, protective time and the working environment temperature was proposed when took into account the comfort requirement of human bodies, clothing thermal properties and heat loss through clothing system. This theoretical model could be used to predict the relationship between the protective material content and the protection time of phase change protective clothing. Experimental results show good accordance with the theoretical prediction.
