What’s the Latest with R-404A?

As another industry workhorse feels the GWP crunch, contractors look at alternatives

May 1, 2017

R-404A is being used by OEMs in new equipment and also on retrofitted equipment. However, because of its high global-warming potential (GWP), the U.S. Environmental Protection Agency (EPA), under its Significant New Alternatives Policy (SNAP) program, has listed R-404A as an “unacceptable” refrigerant in a number of retail food refrigeration categories and in vending machines end-uses.

New Research from NIST Identifies Research Needs for Alternative Refrigerants

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.

Tecumseh Confirms Position on Refrigerant Transition

Company’s position includes approvals for HC and HFO refrigerants

Lubrication Tips for Next-gen Refrigerants

Low-GWP refrigerant transitions cause uncertainty in the land of lubricants

Ron Rajecki

July 4, 2016

As hydrofluoroolefins (HFOs), hydrocarbons (HCs), and natural refrigerants are set to replace HFCs, their often-overlooked partners — lubricants — are rarely mentioned. As the industry prepares to adhere to mandated refrigerant transitions, a common question is: “Can I use my old lubricants with new refrigerants?”

R-22 Replacement Refrigerant Obtains ASHRAE Classification of R-458A
