A little more about Refrigerant Slider
Refrigerant Slider, now a part of Ref Tools, helps you quickly calculate the pressure-to-temperature ratio for more than 80 refrigerants, including natural refrigerants such as ammonia and transcritical CO2. Refrigerant Slider also provides you with information about each refrigerant, including Global Warming Potential (GWP) and Ozone Depleting Potential (ODP). You can switch between the IPCC AR4 and AR5 values, where AR4 values are used in relation to the European F-Gas regulations.

Refrigerant Slider’s P/T calculations use extended curve–fitting models based on Refprop 10 results. You can also see both dew and bubble point for refrigerants with glide.

favorite pt chart app, however it could use some improvements. I would like it if I could have a minimum of 2 pressure points displayed at any time for convenience. the ability to also enter info to calculate subcooling and superheat would be nice as well. Edit: Thanks, I will look into it. I know how to do the calculations in my head, I figured it would be nice to have it right there with my pt chart for visual aid.

Hi Darian, of course we understand it's nice to have everything all in one view. I can note this down as an additional feature request and see what we can do. If you'd like to participate in our alpha testing program please write to coolapp@danfoss.com and perhaps we can work more closely together on new features to future versions of the app.

The latest update causes the app to not work correctly once you have gone into another app. When you go back to the refrigerant slider app, it is completely frozen, requiring you to close it and reopen. Tried resetting the phone (Samsung galaxy note 5) PLEASE FIX
