Retrofit Round-up: Plenty of Options

December 3, 2012
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.

Beyond or Beside HFCs

December 3, 2012
My column in the Nov. 12 issue of The NEWS focused on HFCs, especially low GWP HFCs as retrofits for R-22 systems. This column will focus on what I used to call “beyond HFC” refrigerants, although these days, the term might be “other than HFC” refrigerants.

Winding Down a Complicated Year in Refrigerants

November 12, 2012
It has been an interesting — and complicated — year when it comes to refrigerants. The year began with cutbacks in HCFC production. We had expected there to be about 90 million pounds of virgin R-22 in 2012, down a bit from 2011. But the EPA proposed at the most 80 million pounds and at the least 55 million.
