MIXED REFRIGERANT COMPOSED BY R22 AND R290

摘要

Provided is a binary refrigerant, which improves the quality of monochlorofluoromethane(R22) currently used in a household air conditioner, heat pump or industrial air conditioner, and reduces the ejection temperature at a compressor in a heat pump. The binary mixed refrigerant for an air conditioner/heat pump comprises 70-90 wt% of monochlorofluoromethane(CHClF_2, R22 or HCFC22) and 10-30 wt% of propane(R290).
