ABSTRACT:
Refrigerant type is identified and determined by storing in electronic memory indicia representative of saturation pressure/temperature characteristics of a plurality of differing refrigerant types. A liquid refrigerant sample of unknown type is obtained and vaporized under controlled conditions of temperature and pressure. Refrigerant vapor temperature is measured at two different vapor pressures during the vaporization process, and such temperatures and pressures are then compared with the indicia prestored in memory. Two temperature readings at differing vapor pressures are sufficient to distinguish refrigerant type based upon the prestored saturation/temperature indicia.
