Summary: | PURPOSE: A mixture coolant composition is provided, which can replace chlorodifluoromethane(CHClF2, referred as HCFC-22), does not destroy an ozone layer and is used in a refrigerator and an air conditioner for a car. CONSTITUTION: The mixture coolant composition comprises 50-60 wt% of difluoromethane(HFC-32); 10-30 wt% of 1,1,1,2-tetrafluoroethane(HFC-134a); 10-20 wt% of 1,1,1,2,3,3,3,-heptafluoropropane(HFC-227ea); and 5-15 wt% of isobutane(R-600a). The mixture coolant composition comprises 50-70 wt% of HFC-32; 10-30 wt% of HFC-134a; 10-20 wt% of HFC-227ea; and 5-15 wt% of 1,1,1,2,3,3-hexafluoropropane(HFC-2363a). The mixture coolant composition comprises 50-70 wt% of HFC-32; 10-30 wt% of HFC-134a; 10-20 wt% of HFC-227ea; and 5-12 wt% of butane(R-600). Also the mixture coolant composition comprises 40-70 wt% of HFC-32; 10-40 wt% of 1,1-difluoroethane(HFC-152a); 10-20 wt% of HFC-227ea; and 5-15 wt% of one selected from the group consisting of R-600a. The mixture coolant composition comprises 50-70 wt% of HFC-32; 10-40 wt% of HFC-152a; 10-20 wt% of HFC-227ea; and 5-15 wt% of HFC-2363a. The mixture coolant composition comprises 40-70 wt% of HFC-32; 10-40 wt% of HFC-152a; 10-20 wt% of HFC-227ea; and 5-12 wt% of R-600. |
