There’s An App for That …

This month  we feature the Danfoss Refrigerant Slider App. It provides you access to a user-friendly, quick pressure-to-temperature refrigerant converter. The tool covers more than 80 refrigerants, including natural refrigerants, ammonia, and transcritical CO2. Danfoss provides information such as Global Warming Potential (GWP) and Ozone Depleting Potential (ODP).

The tool is based on NIST Refrigerant Properties and is using the Antoine equations for the conversion. You can see both dew and bubble point for refrigerants with glide.

Please note that the Refrigerant Slider is not a scientific tool and is intended only as a tool for use in the field.

This FREE app is available in both the Apple (ncilink.com/RefrigApp2) and Google (ncilink.com/RefrigApp) App stores..
