| Abstract: | The propane-mixed refrigerant cycle has the advantages of high efficiency and simple. In this paper, the exergy analysis of the cycle is carried out based on the thermodynamic analysis. The exergy loss of the equipment is calculated and the result indicates that the exergy loss of compressors and heat exchangers are contributed about 50% and 26% of the total exergy loss respectively. In this paper, the cause of the exergy loss is analyzed and some measure of reducing the loss is mentioned. |
