Ongoing discussions are currently underway, examining ways to incorporate HFCs into the protocol in order to phase down their use due to relatively high global warming potential (GWP).
The reality is that in 2012, and thus far in 2013, few technicians and contractors are bringing R-22 back for reclamation despite an abundance of capacity at many reclamation facilities.
While the reclamation process may not be meeting industry expectations, numerous manufacturers are offering equipment and devices that make the process easier than ever before.
New refrigerated equipment is being designed to run on so-called natural refrigerants such as ammonia, hydrocarbons, and CO2.
About a month before the AHR Expo, the U.S. Environmental Protection Agency (EPA) indicated it would permit the industry to produce and import 39 million pounds of virgin HCFC-22 in 2013, down from 55 million pounds in 2012.
While much of the buzz at the AHR Expo was on dwindling supplies of new HCFC-22, reclamation of that refrigerant, and use of alternative HFCs in retrofits, a number of conversations centered on alternatives beyond familiar HFCs.
