摘要：
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 degrees C, and the cooling water inlet is 15 degrees C, it is propitious to the inner heat exchange of the gas cooler using the four pipes of phi 6mm x 1mm, and the total heat exchange area of 1.1 m(2).
