Abstract

In this study, a novel integrated thermal management (ITM) system combining vapor injection (VI) with battery heat dissipation was proposed. The model of this novel system was developed and validated. On this basis, the effects of injection pressure, battery heat dissipation, and ambient temperature on the heating performance of the novel system were analyzed. Results showed that a maximum COP based on injection pressure existed for the novel ITM system. Compared with the basic vapor injection system, heating capacity and COP of the ITM system with 1 kW waste heat corresponding to the optimum injection pressure were increased by 13.57% and 7.88% at the ambient temperature of −20 °C, respectively. With the increase in battery heat dissipation from 1 kW to 3 kW, heating capacity and COP were improved by 25.81% and 10.80% at the ambient temperature of −20 °C, respectively. The heating performance improvement of the novel ITM system over the basic VI system gradually diminished with increasing ambient temperature.
