Measurements and calculations of thermodynamic data for the binary refrigerant mixture R22/R114
Abstract Measurements of VLE-data, isochorics in the superheated region, and liquid densities have been carried out for binary mixtures of the refrigerants R22 and R114. VLE-data were measured at five isotherms between −20°C and +60°C, vapour isochorics were measured at four densities and also four compositions up to maximum 100°C, and liquid densities at six compositions up to maximum 80°C. Comparisons with corresponding data of other authors showed good agreements as far as data were available. The Lee-Kesler-Plocker equations of state has been adapted to the measured data by one interaction coefficient. As this equation of state proved to be very suitable for predicting the thermodynamic data of this mixture with small deviations from the measured values; it has been used to calculate log p , h diagrams and h , ξ diagrams for this mixture.
