This paper investigated the performance characteristics of a CO₂ air conditioning system for vehicles. The modified air conditioning system using CO₂ as a working fluid has been developed to apply as one of possible alternatives for mobile A/C system refrigerant. In this study, experiments to analyze cooling performance characteristics have been done with various operating conditions, which are likely to match the actual vehicle’s driving conditions under hot ambient conditions, such as variation of gas-cooler inlet air temperature, evaporator inlet air conditions and compressor speed. Experimental results show that cooling capacity and coefficient of performance(COP) were up to 5.5 ㎾ and 2.7, respectively. Therefore, tested CO₂ A/C system has sufficient cooling performance to cope with cooling load under various actual driving conditions. Furthermore, road tests to apply the developed CO₂ A/C system will be investigated and correlation between bench tests and real road tests will be analyzed after comparing two cases.
