INFLUENCE OF ELECTRONIC EXPANSION VALVE ON HEATING PERFORMANCE OF VEHICLE HEAT PUMP SYSTEM

ABSTRACT
In this paper, based on the regulation characteristics of electronic expansion valve, an experimental platform is built for studying a vehicle heat pump system. Under an ultra-low temperature condition of -10°C, the influence of the super-heat setting value of the electronic expansion valve on the main heating performance parameters of the system is analyzed. The results show that when the superheat setting value of the main valve increases from 2 K to 8 K, the discharge temperature of the compressor increases, the heating capacity of the system decreases by 12.6%, and the compressor power decreases by 15.9%. When the superheat setting value of make-up valve increases from 15 K to 30 K, the discharge temperature of the compressor increases, the heating capacity of the system decreases by 17.7%, and the compressor power decreases by 22.0%.
