Global refrigerant distributor, National Refrigerants, has developed a comprehensive pressure/temperature calculation tool with several special features to make the HVACR technician’s job easier. 

The app can calculate a simple pressure/temperature relationship or calculate superheat/subcool temperatures. 

The user can input pressure or temperature(s) on any screen and the other values are automatically calculated and displayed.

For refrigerant blends, both saturated vapour and saturated liquid values are displayed. Within the superheat/subcool screen, a graphic display for blends will show the entering, mid-point, and outlet temperature as well as line temperature.

The app displays imperial and metric units and includes automatic altitude correction.

It contains all the traditional refrigerants as well as all the new emerging lower GWP alternatives, HFOs and hydrocarbons.

Users can easily choose from a “favourites” refrigerants list and it includes supplementary information about the refrigerants and links to the National Refrigerants website.

The P-T Calculator can be downloaded free from the App Store or Google Play.
