Thermophysical properties of HFC refrigerants

Thermophysical properties of over 100 HFC refrigerants, including single-component and blends.

The table below presents the main thermophysical properties of HFC refrigerants, including single-component and blends. We listed blends that include at least one HFC in their composition. Over 100 HFC refrigerants are listed, and we intend to periodically update this page.


Please click on the arrows marked “Page X of Y” on the upper right corner above the table to browse the entire list and use the horizontal scrollbar to view all the properties. You can also find a specific refrigerant by entering its name in the “Search in table” bar on the upper left corner above the table.

The values of the thermophysical properties presented here are extracted primarily from UNEP sources [1] and [5] which are based on the available reference sources. Only critical temperature and critical pressure values are not reported in these UNEP sources. Critical temperature values and critical pressure values are mainly taken from source [2], except where clearly indicated with the appropriate source number next to the value.
