PURPOSE:To provide a compsn. having excellent characteristics especially as a refrigerant for air conditioners for both heating and cooling and a capability of exhibiting an excellent effect as a refrigerant for freezers as well, by blending chlorodifluoromethane with 1,1,1-trifluoroethane. CONSTITUTION:Chlorodifluoromethane (A) is blended with 1,1,1-trifluoroethane (B) to prepare a refrigerant. It is pref. that 95-40wt.% component A be blended with 5-60wt.% component B. It is more pref. from the viewpoint of a further improved heating ability that 95-80wt.% component A be blended with 5-20wt.% component B. |
