R22 Phase Out - Your Options

Published July 1, 2010 by Stuart Boardman

What is R22 and why is it being phased out?

R-22 is a hydrochlorofluorocarbon (HCFC) and was commonly used in air conditioning, process chiller and industrial refrigeration plant applications. It will soon be phased out due to ozone depletion potential and status as a potent greenhousegas.

These changes in legislation will affect any company that has plant containing R22 refrigerant. R22 was used as alongside the highly ozone-depleting (ODP) CFC’s, but has a relatively low ozone depletion potential. However, even this lower ODP is no longer considered acceptable.

The Montreal Protocol, modified by the EU enforces the end of supply of R22 by 2015, due to the detrimental effect the refrigerant can have on the environment and the ozone layer. Understanding the current market conditions is crucial during the replacement and specification process as critical deadlines are approaching.
