The Castel Regolo APP is able to quickly calculate the relationship between the pressure and temperature of the most common refrigerants 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 depletion potential (ODP).

Within the app it is also possible to make a direct comparison between two different refrigerants, comparing at the same time the difference in saturation temperatures relative to a common reference pressure in the same screen view.

All calculations in the app are performed using extended curve fit models, based on the results of Refprop. In all zeotropic blends, it is also possible to see both the dew point and the bubble point, thus calculating the glide value.
