Abstract
Refrigerant vapor-injection technique has been proved to improve the performance of refrigeration systems, which can mitigate the problem of exhaust overheating and supplement refrigerant flow for compressor at low evaporation temperature. To analyze the refrigeration performance, the evaporation and condensation temperature, heat exchange temperature difference, injecting pressure and evaporator superheat are comprehensively analyzed. The applicability for different refrigerants is extensively evaluated. Compared with the conventional system, the vapor-injection cycle demonstrates better performance especially under severe conditions.
