【Abstract】 In this paper, a new integrated thermal management architecture is proposed based on R134a refrigerant, which uses 9-port valve mode switching to recover waste heat from battery motors, and evaluates its waste heat recovery effect under low temperature driving conditions mainly through compressor energy consumption and COP. In this paper, the AMESIM system model is constructed, the simulation model calibration is carried out based on the basic working condition test data to ensure the credibility of the model, and the simulation comparison between this architecture and other architectures is carried out. The simulation results show that the new integrated architecture studied in this paper can recover the two kinds of waste heat of the battery and motor in the heat pump mode in the cold and low temperature environment. The waste heat recovery capacity is as high as 3.412 kW, and the system energy consumption is reduced to 0.62 kW, which is 50.34% lower than that of the traditional heat pump system. The COP of the system can reach up to 4.465, which is 50.39% higher than that of the traditional heat pump system, and provide a strong guarantee for improving the low-temperature endurance of new energy vehicles.更多还原
