The Regolo APP of Castel is able to quickly calculate the relationship between the pressure and the temperature of the most common refrigerant gases in saturation conditions. The app is able to provide for each refrigerant also the thermodynamic qualities of each gas, including the global warming potential (GWP), and the ozone destruction potential (ODP). Within it is also possible to make a direct comparison between two different gases, comparing at the same time the differentiation saturation temperatures relative to a common reference pressure in the same screen view. All calculations in the slide rule were performed using extended curve fit models are based on the results of Refprop. In all zeotropic gases it is also possible to see both the dew point and the bubble point, thus allow the user to calculate the glide value.
