A novel CO2heat pump system with Series Gas Cooler (SGC) configuration was proposed for application in an Electrical Vehicle (EV). A newly developed mobile CO2compressor with 6.8 ml displacement and 8000 RPM maximum speed was employed. The heating performance of this CO2heat pump system was experimentally evaluated under low temperature conditions. Comparison experiments were conducted to reveal the effects of CO2refrigerant charge, GC configuration and indoor return air ratio on heating performance characteristics. Results show that using SGC improves the heating capacity and COP by up to 33% and 32%, respectively, compared with One Gas Cooler (OGC). At the extreme cold temperature of −20 °C, the novel CO2heat pump system achieved 5.6 kW maximum heating capacity and 1.8 COP, which greatly outperforms the conventional PTC heating supplement for an EV.
