Abstract

Dimethyl ether(DME)can be used as refrigerant because it has a property to liquefy easily at roomtemperature,0.53MPa. In this report, using DME as a refrigerant is numerically evaluated by a comparisoncoefficient of performance(COP)at standard refrigeration cycle and single or double stage compressionrefrigeration cycle at-30℃ between a DME refrigerant and conventional refrigerants. The results showedthat the DME refrigerant is superior as compared with conventional refrigerant in term of COP at standardrefrigeration cycle.
