PURPOSE:To produce novel refrigerants which do not or hardly cause the problem of ozonosphere disruption. CONSTITUTION:The following novel refrigerants are provided: one essentially contg. HFC 32, HFC 134a, and HFC 143a (except one contg. 1-45wt.% HFC 32, 30-80wt.% HFC 134a, and 0-70wt.% HFC 143a); one essentially contg. HFC 32. BFC 125, and HFC 143a; one essentially contg. HFC 134a, HFC 143a, and BFC 152a; one essentially contg. HFC 32, HFC 134a, and HFC 152a; and one essentially contg. HFC 32, HFC 125, and HFC 134a (except one contg. 60wt.% or lower HFC 32, 85wt.% or lower HFC 125, and 15-80wt.% HFC 134a). |
