ORLANDO, Fla. — It looks like the spigot of new HCFC-22 will be totally shut off as of 2020. The so-called “service tail” of HCFCs from that date until 2030 apparently will not include the most widely used refrigerant in the HVACR sector.
That was the perspective of Dave Godwin, environmental engineer for the U.S. Environmental Protection Agency (EPA), who spoke Sept. 9 at the Food Marketing Institute Energy & Technical Services Conference. “As of 2020, only stockpiled or reclaimed supplies [of R-22] will be available,” he told supermarket engineers and suppliers.
In a brief interview with
The NEWS, he said the service tail more than likely would include the HCFC-123 used in some chiller applications.
His comments clarify some of the allocation questions raised last summer during an EPA presentation on HCFC phaseouts, at which time some in attendance at the Washington conference thought the tail might consist primarily of R-22.
The mandated phaseout of HCFCs is currently at 65 percent of the baseline year of 1996. It will drop to 25 percent of the baseline in 2010, and to 10 percent in 2015. Overall, new production of HCFCs as of 2020 is to fall to 0.5 percent of 1996 levels, with that 0.5 percent making up the service tail.
Besides R-123, Godwin said it also could include R-124 used in sterilization processes, and R-225 used in solvents.
