摘      要：Ejector can utilize high pressure energy from liquid mechanism,it can be used in heat pump system coupled with economized vapor injection(EVI)scroll *** running under low temperature conditions,the performance of the EVI system with ejector can be improved *** this paper,the design method of the heat pump system with ejector is presented,and the process for designing the heat pump with ejector(EVIe)was *** prototype heat pump was designed under the condition of the evaporation temperature of -20oC,and an experimental setup was established to test the *** measured results demonstrated that the heating EER(energy efficiency ratio)of the EVIe could reach about 4%higher than that of the system without the ejector when the heating capacity remained nearly *** design method is helpful to development of a heat pump system coupled with scroll compressor and ejector.
