Abstract
The paper presents a new method for predicting pseudocritical characteristics of refrigerant-oil mixtures (ROM), based on the use of limited experimental information contents. For calculating pseudocritical parameters of ROM, the proposed models utilize scaling equations with few constants and universally changing effective exponents. The predicted results are shown for pseudocritical characteristics of the R600a/Azmol, R600a/Reniso WF15А and R245fa/Planetelf ACD 100FY mixture solutions.

Keywords: refrigerant-oil mixture, pseudocritical temperature, scaling equation, capillary constant, surface tension, saturated vapour pressure.
