Claim Text:
1. A method for filling a refrigerant mixture comprising difluoromethane and 2,3,3,3-tetrafluoropropene, the difluoromethane being present in a liquid phase in an amount of 10 to 90 wt % based on 100 wt % of the total of the difluoromethane and 2,3,3,3-tetrafluoropropene, the method comprising, in transferring the refrigerant mixture in a liquid state to a target container or equipment from a feeding container, adjusting, immediately before the transfer, the proportion (initial composition) of the difluoromethane in the liquid phase of the refrigerant mixture in the feeding container to x+y wherein ±a is a set tolerance (a≧0); x is a target composition with the proviso that 10≦x≦90, excluding a range satisfying an inequality: y wherein L
