| 摘要 |
The present invention relates to a mixed refrigerant composition containing chlorodifluoromethane (R22 or HCFC22) and tetrafluoroethane (R134a), and more specifically, to a mixed refrigerant composition containing 49-51 wt% of chlorofluorocarbon and 49-51 wt% of hydrofluorocarbon. The mixed refrigerant of the present invention maintains a discharge temperature and reduces power consumption by improving the performance of existing HCFC22.
