At its booth this year, Arkema took the opportunity to promote R-32 as a transition refrigerant for the air conditioning market. Arkema’s global business director of fluorochemicals, Matthew Ritter, said that while the company does not necessarily believe that R-32 will be the final answer, it is a very good choice for that segment of the market.
Last December, EPA proposed to modify the use conditions required for use of three flammable refrigerants — isobutane (R-600a), propane (R-290), and R-441A — in new household refrigerators, freezers, and combination refrigerators and freezers under the Significant New Alternatives Policy (SNAP) program to reflect an updated standard from Underwriters Laboratories (UL).
ACCA is dedicated to creating a high-quality technician training program on flammable refrigerants. As the HVACR industry works to phase down refrigerants with high-global warming potential (GWP), ACCA members have been concerned that contractors and technicians need more time to be prepared to safely handle the next generation of refrigerants, which includes flammable products.
Focus is safely maintaining and servicing systems that use flammable refrigerants
October 30, 2017
RSES has released the third edition of its Hydrocarbon Refrigerants study guide and eLearning course. The study guide and eLearning course are designed to assist HVACR professionals in understanding the requirements to safely maintain and service systems that utilize flammable refrigerants currently approved under the Environmental Protection Agency’s Significant New Alternatives Policy (SNAP) Program.
Danfoss launches latest Application Development Center in Florida
August 2, 2017
Danfoss’ latest “Engineering Tomorrow” Application Development Center in Tallahassee, Florida, will be able to test mildly flammable refrigerants at global nameplate voltages, with real-time data acquisition and performance.
Residential and commercial ‘worst-case scenarios’ included in A2L research
July 5, 2017
The Air-Conditioning, Heating, and Refrigeration Technology Institute (AHRTI) — the research arm of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) — released the first research report as part of its ongoing testing of flammable refrigerants, many of which were identified as possible replacements to high-GWP (global warming-potential) hydrofluorocarbons (HFCs) that will be phased down under the Montreal Protocol.
Researchers must look beyond nonflammable chemicals
April 3, 2017
NIST’s study, entitled “Limited options for low-global warming potential [GWP] refrigerants,” focused on residential and small-commercial single-package and split air conditioning systems, but the authors said their conclusions also generally apply to room air conditioning units and other refrigeration and heat-pump systems currently using common, ozone-depleting refrigerants such as R-410A or R-22, which are still used in some developing countries today. “The takeaway is there is no perfect, easy replacement for current refrigerants,” NIST chemical engineer Mark McLinden said.
Incorporating flammable refrigerants into manufacturing processes can have a dramatic impact on your facility from testing procedures to reclassification as a hazardous location to modifying or building new labs.
