摘    要:矿井救生舱是与外界完全隔绝的密闭空间,人员在内部生存会产生热、湿,导致舱内温度、湿度升高,危及人员生命安全,因此,制冷系统是矿井救生舱内生命保障系统的关键组成之一。设计了一套适合于开式二氧化碳制冷系统的翅片式不锈钢换热器,试验研究表明,电加热器加热功率1 500 W,模拟人员舱内温度和湿度分布维持在30.3 ℃和77.5%。考虑换热器的换热性能、安全性能及材料成本等因素,与同换热面积的紫铜换热器相比,不锈钢换热器综合性能最佳。

关 键 词:矿井救生舱;开式;二氧化碳;不锈钢换热器

Abstract:Mine refuge chamber is a confined space.The temperature and relative humidity increase because of the heat and moisture from skin of the trapped persons,which will endanger the lives.Consequently,refrigeration system is a key component of the life support in the mine refuge chamber.A stainless steel heat exchanger adapt to opening carbon dioxide refrigeration system was designed.When the heat power is 1 500 W,the temperature,relative humidity of the analog chamber are 30.3 ℃,77.5%,respectively.Compared to copper heat exchanger,stainless steel heat exchanger is better according to the heat transfer efficiency,safety performance and material costs.
Keywords:mine refuge chamber;opening;carbon dioxide;stainless steel heat exchanger
