The vapor compression/ejection refrigeration system (VCERS) is an energy-saving system which can reduce the loss of throttling expansion and the pressure ratio of compressor to improve the efficiency of the refrigeration system. The structure of ejector related with the evaporating and condensing temperature is researched and the energy-saving effects are compared with the compression refrigeration system from the refrigerating capacity
the compressor work and COP on five working conditions. The results indicate that the VCERS is more suitable for the low temperature working condition
the maximum increase of refrigerating capacity is about 29%
the maximum decrease of the compressor work is about 65% and the maximum increase of COP is about 63%.
