| titleOfInvention | Refrigerant composition comprising three hydrofluorocarbon components |
| abstract | A refrigerant composition suitable for air conditioning, refrigeration and heat pumping applications consists essentially of three hydrofluorocarbon (HFC) components selected from R134a (HFC134a), R125 (HFC125) and R143a (HFC143a). The refrigerant composition comprises 10-20% R134a, 40-65% R125 and 15-50% R143a, where the three components sum to give a total of 100%. The three components may be combined together in various proportions. Preferably, the refrigerant composition meets the criteria for safety classification A1 or A2 of ASHRAE Standard 34, with regard to toxicity and flammability. Preferred compositions comprise near azeotropic and zeotropic refrigerant compositions which are non-flammable under all conditions of fractionation. The refrigerant may be used in a refrigeration or air conditioning unit with a synthetic oxygen-containing lubricant such as a polyol ester or a polyether. Preferably, the refrigerant is used in a hermetic, semi-hermetic or open refrigeration, air conditioning or heat pump unit, driven by an external power source, to provide refrigeration cooling temperatures in a range from 0{C to -45{C, air conditioning cooling temperatures in a range from 0{C to 20{C, or heat pumping warming temperatures in a range from 15{C to 50{C. In use, the refrigerant composition is designed to replace R22 (HCFC22) in new equipment. |
