PCT No. PCT/JP96/01008 Sec. 371 Date Mar. 18, 1997 Sec. 102(e) Date Mar. 18, 1997 PCT Filed Apr. 15, 1996 PCT Pub. No. WO96/33377 PCT Pub. Date Oct. 24, 1996The present invention provides A method for charging a refrigerant blend, when using as a refrigerant a non-azeotropic blend whose permissible range falls within 22 to 24% of difluoromethane, 23 to 27% of pentafluoroethane and 50 to 54% of 1,1,1,2-tetrafluoroethane, comprising adjusting a composition of non-azeotropic blend in a feeding container to the level of 23.5 to 24.0% of difluoromethane, 25.5 to 26.0% of pentafluoroethane and 50.0 to 51.0% of 1,1,1,2-tetrafluoroethane, discharging and transferring the non-azeotropic blend from the feeding container in liquid phase into another container in which a refrigerant is used so as to allow the composition change associated with the transfer to fall within the permissible range; and a method for producing a vapor compression refrigerating equipment.
