| Abstract: | In this paper,a new group of refrigerants was chosen to replace the R12/R13/R14 of the auto-cascade refrigeration system,which is no damage to the ozone layer.The selection principle of refrigerant group was put forward,and then,the ratio of refrigerant group experiments was carried out on the experimental apparatus as to find the optimal ratio.Finally,we compared the temperature derating and cooling capacity of the R12/R13/R14 system to the R134a/R23/R14 system which with 5L coolant. |
