According to the character of the trans-critical CO2 cycle, this paper develops the theoretical model of the gas cooler using the distributed-parameter method. At last, it optimizes the gas cooler. The comparison between the simulation and the experiments indicates: under different inlet temperature of cooling water, high pressure and mass flux of the refrigerant, the maximum deviation between the simulation and the experimental results is 5.6%, 10.1% and 19.7%,respectively. The optimal results indicates: when the refrigerant inlet is 8MPa and 93°C,and the cooling water inlet is 15°C,it is propitious to the inner heat exchange of the gas cooler using the four pipes of φ6mm×1mm, and the total heat exchange area of 1.1 m2.
