Résumé
In this study, a CO2 automotive air-conditioning prototype system was designed and constructed and the performance of the system was experimentally investigated in detail. The compressor was of swash plate design; the gas cooler and evaporator of the system were made of fin tubes; a manual expansion valve and an internal heat exchanger accumulator were used. The lubricant, the CO2 charge level, 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 were varied and the performance of the system was investigated. The cooling capacity, compressor power consumption, CO2 mass flow rate, and COP value were analysed. Analysis of the fluctuations of the system pressure and temperature is also provided. The results are presented in graphical form, suitable operation conditions are determined and further improvements of the system are also discussed.
