Résumé

In this study, a CO2 automotive air conditioner prototype is designed and constructed. The compressor is of swash plate design; the gas cooler and evaporator are made of fin-tubes; a manual expansion valve and an internal heat exchanger accumulator are used. The lubricant, the CO2 charge, the evaporator outlet pressure, the compressor speed, the air inlet temperature and flow rate of the gas cooler and the air flow rate of the evaporator are varied and the performance of the prototype is experimentally investigated in detail. The cooling capacity, compressor power consumption, CO2 mass flow rate, and COP value are analyzed. The experimental results show that the CO2 system performance is greatly affected by different lubricants; the CO2 system performance is sensitive to the mass charge; the high side pressure affects the system performance greatly and a high side pressure controller is needed.
