Abstract
A new type of liquid-separating condensing compression/ejector refrigeration cycle is proposed,and the thermodynamic analysis of new cycle is developed in this paper.The zeotropic working fluid R32/R1234yf is used as the work fluid.The influence of fluid components,quality,evaporating temperature and condensing temperature on the cycle performance is analyzed,and the performance of the new cycle and the traditional cycle are compared.Finally,an exergy analysis of the new cycle is analyzed.The results show that,under the same conditions,the new cycle can improve the performance by up to 27.3%compared with the traditional dual-evaporation compression/ejector refrigeration cycle.The fluid components have a greater impact on the cycle performance,when the mass fraction of R32 is 0.9,the exergy destruction is the largest.When the mass fraction of R32 is 0.3,the exergy efficiency is maximum,and the exergy destruction occupied by the high-temperature evaporator,compressor and low-temperature condenser is 76.4%,9.8%and 3.0%,respectively.Increasing the evaporating temperature or reducing the condensing temperature can effectively improve the performance of the new cycle.关键词
