Predicting saturated liquid densities of refrigerants using the SVRC framework
Our scaled-variable-reduced-coordinate (SVRC) framework for correlating saturation properties was used to correlate saturated liquid densities of a wide variety of refrigerants at temperatures from the triple point to the critical point. In general, the SVRC model is capable of representing the phase densities of refrigerants within their experimental uncertainties when two adjustable parameters are used for each substance. Beyond precise representation of existing data, the SVRC framework is capable of generalized saturation property predictions. The model yielded average errors of less than 0.5% for the densities, based on a single experimental measurement. This level of accuracy is comparable to that we reported previously for refrigerant vapor pressure predictions.
