THE PRESENT INVENTION PROVIDES A METHOD FOR CHARGING A REFRIGERANT BLEND CHARACTERIZED IN THAT, IN CASE OF EMPLOYING AS REFRIGERANT A NON-AZEOTROPIC BLEND COMPRISING 23BY WEIGHT OF DIFLUOROMETHANE, 25BY WEIGHT OF PENTAFLUOROETHANE AND 52OF 1,1,1 ,2-TETRAFLUOROETHANE, COMPOSITION CHANGE ASSOCIATED WITH TRANSFER IS ALLOW TO FALL WITHIN THE PERMISSIBLE RANGE OF PERFORMANCE OF THE NON-AZEOTROPIC REFRIGERANT BLEND BY ADJUSTING A COMPOSITION OF THE NON-AZEOTROPIC BLEND IN A FEEDING CONTAINER SUCH AS BOMB TO 23.5-25.0BY WEIGHT OF DIFLUOROMETHANE, 23.5-25.0BY WEIGHT OF PENTAFLUOROETHANE AND 50.0-53.0BY WEIGHT OF 1,1,1 ,2-TETRAFLUOROETHANE FOLLOWED BY DISCHARGING THE NON-AZEOTROPIC BLEND FROM A LIQUID PHASE AT 40°C. OR LESS. ACCORDING TO THE CHARGING METHOD, COMPOSITION CHANGE ASSOCIATED WITH TRANSFER OF NON-AZEOTROPIC HFC32/HFC125/HFC134A REFRIGERANT BLEND MAY BE ALLOWED TO FALL WITHIN THE PERMISSIBLE RANGE OF PERFORMANCE OF REFRIGERANT.
