矿用可移动式救生舱制冷技术现状分析

Analysis of Refrigeration Technology in Mobile Coal Mine Refuge Chamber

简要分析了矿用可移动式救生舱热负荷的来源,介绍了目前国内矿用可移动式救生舱研发单位所采用的舱体隔热及制冷技术,并进行了优缺点分析。认为冰蓄冷系统在安装、移动完毕后不能立即投入使用,制冷系统不能实现无缝对接,且维护成本较高;液态二氧化碳节流膨胀制冷系统可在无任何外部动力的情况下,实现制冷、除湿、净化一体化,但其不适用于高温矿井,且二氧化碳一旦泄露,对人体将造成致命伤害,要求系统的可靠性较高。

Briefly analyzed heat load source of the mobile coal mine refuge chamber, introduced the insulation and refrigeration technology of current mobile coal mine refuge chamber factories used, and analyzed the advantages and disadvantages. Ice storage system can＇t be used immediately after the refrigeration system was installed ,so it can＇t achieve synchronization, it also need high maintenance costs;throttling expansion of liquid carbon dioxide refrigeration system can be achieved integration of refrigeration dehumidification and purification in the absence of any external force ,but it does not apply to high temperature coal mine, when carbon dioxide disclosed, it would cause fatal damage to the human body, so requiring the system high reliability.
