摘要：
In order to solve the problem of serious attenuation of the performance of heat pump air conditioning system for pure electric bus at high temperature in summer and at low temperature in winter, a heat pump air conditioning system for medium-pressure air-supply pure electric bus with economizer is developed. The performance of the system working at from +50 degrees C to -20 degrees C ambient temperature and at different compressor speed is studied. The results show that the exhaust temperature of the compressor can be reduced greatly.
