Now, more than ever, the industry has been looking for alternatives to R-22 to keep the huge existing base of R-22 equipment up and running. More reclamation has been one option. But at the same time, attention is being paid to a large number of HFC refrigerants that can be retrofitted into R-22 equipment.
Because no one HFC refrigerant can be retrofitted efficiently into the entire range of R-22 equipment, a wide and sometimes changing variety of HFCs have entered the market. The NEWS contacted a number of refrigerant manufacturers asking them to discuss some of their most popular HFCs for R-22 retrofits.
Two recent projects demonstrated successful retrofitting of HFC refrigerants into existing HCFC-22 systems. These projects, which were highlighted by Arkema, detail the processes with regard to HFC-427A in refrigeration and air conditioning applications.
Fresh on the heels of the announcement of an almost 50 percent reduction in supplies of virgin HCFC-22, the supermarket industry is reacting. What are they focusing on now?
