There’s An App for That …
This month‘ our featured app is from National Refrigerants. It is a comprehensive Pressure/Temperature calculation tool with several features designed to make the HVACR technician’s job easier.
It calculates a simple pressure/temperature relationship or superheat/subcool temperatures. Techs input pressure or temperature(s) on any screen and the other values are automatically calculated and displayed.
For refrigerant blends, both saturated vapor and saturated liquid values are displayed. Within the superheat/subcool screen, a graphic display for blends shows entering, mid-point, and outlet temperature.
