| 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. |
