EXPERIMENTAL STUDY ON PERFORMANCE OF HEAT PUMP AIR CONDITIONING SYSTEM FOR PURE ELECTRIC BUS WITH ECONOMIZER

ABSTRACT
When the exhaust temperature of heat pump air conditioning system of pure electric bus is too high, the performance of the system is attenuated. In order to solve the problem, an alternative system with low pressure air supply is developed. The experimental platform is set up to reveal the main factors affecting the refrigeration and heating performance of the system. The results show that the low pressure air-supply technology can significantly reduce the exhaust temperature of the compressor.
