| Summary: | In this study, a heat pump system with two dehumidifying and reheating modes for electric vehicles was set up, and the operating characteristics of the heat pump system were compared in two dehumidifying and reheating modes under various test conditions. Test results showed that energy consumption of the heat pump system was below 2.0 kW, and COP was above 2.0 under all test conditions. The dehumidifying and reheating mode A has better dehumidification performance with moisture extraction rate ranging from 0.41-0.83 kg/h and heating capacity ranging from 1.7-3.0 kW, while dehumidifying and reheating mode B has better reheating performance, with moisture extraction rate ranging from 0.25-0.55 kg/h and heating capacity ranging from 2.0-3.4 kW. Based on the characteristics of two modes, an energy saving strategy was proposed as a possible option for realization of energy conservation without sacrifice of thermal comfort for passengers. |
