Abstract
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 23% by weight of difluoromethane, 25% by weight of pentafluoroethane and 52% of 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 23.5-25.0% by weight of difluoromethane, 23.5-25.0% by weight of pentafluoroethane and 50.0-53.0% by weight of 1,1,12-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.
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.
