Résumé

This paper experimentally evaluates the cooling and heating performance of CO2 and R134a heat pump systems applied in electrical vehicles. A mobile scroll type electrical compressor with 27 cc displacement was used for R134a system, and a commercial rotary type electrical compressor with 6 cc displacement was adopted for CO2 prototype system. Comparative experiments were carried out for these two systems in the calorimeter test facility. In addition, the effects of compressor speed, outdoor air temperature, outdoor air velocity and indoor air inlet temperature on system performance were also investigated. Experimental results concluded that CO2 system achieves comparable cooling capacity with R134a system, and performs a high heating COP and heating capacity in a cold climate. The advantage of CO2 heating performance will contribute to extending the driving range of electrical vehicles in a cold climate and making CO2 refrigerant more promising in the field of automobile air conditioner.
