摘要
在井下开采的金属矿、煤矿等矿山的避难硐室内,目前普遍采用压缩制冷循环、蓄冰等方式进行制冷。高压常温储存的空气可通过等熵膨胀、等焓节流等过程实现制冷,有无需外界提供动力的优点,同时空气能够满足遇险人员的呼吸需求。本论文提出了空气开放式膨胀节流制冷系统的可行方案,并分析了影响制冷需求和空气用量的主要因素。
Compression refrigeration and ice storage are being widely used in underground mines of metal, coal, etc. Air stored at high pressure and usual temperature can achieve refrigeration through isentropic expansion and/or adiabatic throttling process in absence of external power. At the same time, the air after the pressure reduction is able to satisfy the respiratory needs of persons in distress. This paper presented a feasible program of super-critical air open refrigeration system, and analyzed the main factors affecting the amount of cooling demand and air consumption.
