Finding R-22 and R-410A alternatives for high-ambient-temperature environments
March 7, 2016
The Oak Ridge National Laboratory (ORNL) High-Ambient-Temperature Evaluation Program for low-global warming potential (GWP) refrigerants aims to develop an understanding of the performance of low-GWP alternative refrigerants to HCFC and HFC refrigerants in mini-split air conditioners under high-ambient-temperature conditions.

Johnson Controls announced it is enhancing its HFC product lines to be fully compatible with the non-flammable, low-global warming potential (GWP) refrigerant Opteon™ XP10 (R-513A) manufactured by The Chemours Co. York centrifugal and screw chillers ranging from 125 to 6,000 tons (440 to 21,100 kW) are compatible with R-513A.
Adoption of lower GWP refrigerants by supermarkets is vital if European HFC phase-down targets are to be met

Honeywell’s Solstice®N40 (R-448A) refrigerant for supermarket refrigeration has been named a finalist for the R&D 100 Awards. The R&D 100 Awards, sponsored by R&D Magazine, honor the 100 most innovative technologies and services of the past year.
HVACR industry leaders and White House officials gathered today at the Eisenhower Executive Office Building in Washington, District of Columbia, to reaffirm their 2014 pledge to invest $5 billion over 10 years in the research, development, and commercialization of low-GWP (global warming potential) refrigerants.
The U.S. Environmental Protection Agency’s (EPA’s) final rule, announced July 2 and published in the Federal Register on July 20 (Federal Register Vol. 80 No. 138, July 20, 2015, 42870-42959), will — among other things — change the listing for certain refrigerants used for retail food refrigeration.
