is proposed as a substitute for R22 in this paper.The thermophysical properties of this environment-friendly mixture and its refrigeration system performance are theoretically analyzed with the software Refprop 8.0.The results show that the COP and the unit volume refrigerating capacity of the system with the new refrigerant mixture is equivalent to those with R22 under the standard working condition.Under the variable working condition
