| 摘要 |
A method of filling a refrigerant mixture comprising a nonazeotropic mixture composed of difluoromethane, pentafluoroethane and 1,1,1,2-tetrafluoroethane contained in an allowable range of respective quantities of 22-24 %, 23-27 % and 50-54 %, wherein the mixture is drawn out of the liquid phase in the container on the feed side while adjusting the percentage composition thereof to 23.5-24.0 % difluoromethane, 25.5-26.0 % pentafluoroethane and 50.0-51.0 % 1,1,1,2-tetrafluoroethane to thereby control the compositional change resulting from refrigerant transfer to fall within the above allowable range; and a process for producing a vapor-compression refrigerator.
