| Abstract: | The contribution of internal heat exchanger of CO2 cycle was analyzed in this paper.For CO2 heat pump system,the results indicated that the improvement of COP and volumetric capacity is less than 6%.For CO2 refrigeration system,when the condensation temperature is below 40℃,the improvement of COP and volumetric capacity is less than 10%;When the condensation temperature is between 40℃ and 70℃,the improvement of COP and volumetric capacity is significant and between 10% and 20%. |
