Abstract
Since electric vehicles are handicapped by limited battery power, the HVAC system in electric vehicles significantly impacts its power consumption and driving range. This can be more serious in winter. A heat pump can be suggested for improving the heating performance of the HVAC system in an electric vehicle. In this study, a heat pump using gas injection technique with phase separator was investigated theoretically in the electric vehicle to improve the heating capacity and efficiency at low ambient temperature. A simulation model for this system was developed and validated with the experimental data. It was used to analyze the effects of gas injection technique on the system performance and compressor stability. The simulation results were consistent with the measured data. The results showed that the gas injection technique improved the performance and efficiency of the electric vehicle heat pump. The heating capacity and COP were improved by approximately 22% and 19%, respectively, at the outdoor temperature of -20°C due to the use of the gas injection technique.
