R22 Refrigerant - Properties
Properties of Refrigerant R22 Dichlorodifluoromethane - saturated liquid and saturated vapor - imperial and metric units.
R22 is a single HydroChloroFluoroCarbon (HCFC) compound. It has low chlorine content and ozone depletion potential and a modest global warming potential. ODP1) = 0.05 and GWP2) = 1700
R22 can be used in small heat pump systems, but new systems can not be manufactured for use in the EU after 2003. From 2010 only recycled or saved stocks of R22 can be used. It will no longer be manufactured.

R417A is the zero ODP1) replacement for R22 suitable for new equipment and as a drop-in replacement for existing systems.
1) ODP - The ODP or Ozone Depletion Potential. The potential for a single molecule of the refrigerant to destroy the Ozone Layer. All refrigerants use R11 as a datum reference where R11 has an ODP of 1.0. The less the value of the ODP - the better the refrigerant is for the ozone layer and the environment.
2) GWP - The GWP, or Global Warming Potential. A measurement (usually measured over a 100-year period) of how much effect a refrigerant will have on Global Warming in relation to Carbon Dioxide. CO2 has a GWP of 1. The lower the value of GWP - the better the refrigerant is for the environment.
