Abstract：
 Arefrigerant for heat pump of high-temp water source is prepared from monochloroe-1,2,2,2-tetrafluoroethane (HCFC-124), 1-monochloro-1,1-diffluoroethane (HCFC-1426) and optional isobutyane (HC-600a) through proportional pysical mixing. Its advantages include no damage to ozonosphere, no poison, imbustible nature, and high thermodynamic performance. It can directly use freon-22 refrigerating system and need not to change the compressor and main parts in the system.
