A Review on Ejector-mechanical Compression Hybrid Refrigeration Cycle
【摘要】 喷射制冷具有利用低品位能源获取制冷效果的优点,但性能系数较低;机械压缩制冷具有性能系数高的优点,但消耗的是高品位电能。喷射/压缩复合制冷正是利用上述2种循环各自优点来提高能源综合利用效率,从其系统特点来看,主要可分为3种系统形式。本文从喷射/压缩复合制冷循环、制冷工质应用、喷射/压缩复合制冷循环的应用领域等方面介绍该技术研究及现状分析,并对其发展提出展望。
【Abstract】 Ejector refrigeration has the advantage of using low grade energy to obtain refrigeration effect,but its coefficient of performance( COP) is lower. Mechanical compression refrigeration has high COP,but it consumes high grade energy. An ejectormechanical compression hybrid refrigeration cycle improves the efficiency of comprehensive utilization of energy by combining both of the advantages. According to the characteristics of the system,it can be divided into three main types of cycles. A comprehensive review was conducted on ejector-mechanical compression hybrid refrigeration system in terms of principle,refrigerants and application fields. Possible future research topics were also discussed.
