Simulation Study on Characteristics of Ultra-Low Temperature Heat Pump Air Conditioning System for Pure Electric Vehicles

Abstract:

In view of high discharge temperature of compressor, the heating performance attenuated seriously, even unable to work properly and other issues of normal heat pump air conditioning system for electric vehicles under low temperature conditions, a gas-mixing heat pump air conditioning system for pure electric vehicles is designed. Based on the first law of thermodynamics and coupling properties among all components, the mathematical model of this system is established. The analog computation of main performance parameters of this system is carried out by this model, having a better match in comparison with experimental results. By simulation, the results show that the system can effectively solve the problems of high exhaust temperature from compressor and heating performance attenuation seriously of non-gas-mixing heat pump air conditioning system for pure electric vehicles under low temperature condition.
