Although the advantages of Using mixture refrigerants are well known, they have not often been used. One reason for this is the nonavailability of reliable , and readily useable information on their thermodynamic and transport properties. Even the properties of the azeotropic, mixture R501 (75 percent R22 and 25 per-' cent R12 by weight) are not-yet well established. The purpose of this study is to compile and complement previous work on the R22/R12 system and to present in one place reasonably reliable predictive , methods and tabulated values for determining the properties of mixtures of R22' and R12 of any concentration.
