Abstract : The role of refrigerants has changed greatly during the last 20 years. Today, almost the total refrigeration industry is based on ammonia, Freon-12, and Freon-22. Freon-22 is used in 20-30% of the large and small refrigerators, and in 40-50% of air conditioners. Freon-22 is noncombustible, and not explosive. It does not have an unpleasant odor like ammonia, and is less toxic. Freon-22 has a higher refrigerating capacity than Freon-12, and a much higher (by about 30%) coefficient of heat transfer during boiling and condensation. The low solubility of Freon-22 in oil leads to good separation. Although the consumption of Freon-22 has increased, its thermophysical properties have not yet been sufficiently studied. The Leningrad Technological Institute of Refrigeration studied the properties of Freon-22, and compiled tables of thermodynamic properties of this substance from newly published data.
