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.
