The Refrigerant Slider is an essential tool for HVACR professionals and gives you access to a user-friendly, quick pressure-to-temperature refrigerant converter. The tool covers more than 80 different refrigerants, also including natural refrigerants and you will find information about the various refrigerant types including ammonia and transcritical CO2. This includes information such as Global Warming Potential (GWP) and Ozone Depleting Potential (ODP). You can switch between the IPCC AR4 and AR5 values, where the AR4 values are used in relation to the European F-Gas regulations.

The calculations are based on extended curve fitting models based on Refprop 10 results. You will be able to see both dew and bubble point for refrigerants with glide.

How to use
On the left side of the screen a slider quickly helps you find the pressure or temperature reference. On the right side you can find the precise pressure and temperature. You can type in the precise pressure or temperature reading, and Refrigerant Slider will instantly give you the corresponding figure and move the slider for visual indication.
You can easily change pressure and temperature units within the most used metric (SI) and imperial units and switch between gage and absolute pressures as you please.
