摘要：
In order to optimize the CO2 trans-critical refrigeration cycle system, achieving a balance between the efficiency and economy. Exergoeconomic analysis is proposed and the mathematical models are established, the variation trend of the COP, exergy efficiency, exergy loss of each component and the economic cost of exergy with the increase of the outlet temperature of the gas cooler is simulated and analyzed. The results show that the COP and the exergy efficiency decrease. The exergy loss of compressor, gas cooler and throttle all increase to different extent, except for a slight decrease of the evaporator. The cost per unit of exergy of the product also decline. Reducing exergy loss caused by throttle valve is conducive to improve the efficiency of the system. © 2020, Editorial Board of Acta Energiae Solaris Sinica. All right reserved.
