Codes and Standards for low-GWP Refrigerants
2017/04/14
Apr 12, 2017
・ The regulatory train may have slowed in Washington, but the move to new refrigerants continues.
As I write this, President Trump is signing an executive order to roll back the Obama Climate Initiative.  Will this change of policy mean that the HVACR industry’s move to new, low-GWP refrigerants is ending? Not at all. The industry continues to phase down the use of HFCs.  We are testing new refrigerants and continue to redesign equipment to accommodate them.  Equipment manufacturers are driven by a domestic and global market which is demanding a move away from HFCs like R-134a and R-407A which are potent greenhouse gasses.  So, with or without leadership from Washington, the trend continues.
 
Over the past two years, the EPA has issued rules that will phase out certain HFCs in most applications.  Some of the rules, under the Significant New Alternatives Policy (SNAP) have already taken effect and more will be coming into force over the next seven years.  We cannot expect that any of the regulations already issued will be withdrawn in the current administration.  So, we need to continue to work to safely accommodate equipment that will use the new refrigerants.
