矿用救生舱热环境分析

摘要

通过对救生舱进行传热特性的实验研究,确定了救生舱等效传热系数和系统平均热容值。并对舱内各种热源进行了分析,确定了其热载荷的计算方法;最后根据救生舱标准规定的环境参数,通过舱内热平衡原理得出了该工况救生舱制冷系统所需最大制冷量。%Determined the overall heat transfer coefficient and heat capacity of chamber by experiments.Analyzed all the heat sources in the chamber and determined the calculation method of thermal load.According to the environmental parameters in the standard,the maximum refrigerating output of refuge chamber was obtained by establishing a heat balance.
