ASHRAE, with the consensus of the American National Standards Institute (ANSI), has designated Bluon Energy’s TdX 20 refrigerant as an approved standard to refrigerant blends under Standard 34-2013. TdX 20 has been given the designation of R-458A.
RS-45 said to be a true drop-in replacement for R-22
September 7, 2016
ComStar International Inc. has announced a new refrigerant for ice rink managers to comply with the phaseout of R-22 refrigerant. The company said its replacement refrigerant is for use in flooded liquid overfeed ice rink systems and does not require changing components or oil.
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?”
TdX 20 is a multi-phase, zeotrope refrigerant blend
June 13, 2016
Refrigerant manufacturer Bluon Energy announced that its TdX 20 refrigerant was given the preliminary ASHRAE number of R-458A with an A1 safety rating. The final approval and assignment of the ASHRAE classification is anticipated by the end of June 2016.
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.
Home appliance manufacturers previously transitioned away from CFCs and HCFCs
February 23, 2016
The Association of Home Appliance Manufacturers (AHAM) has announced a goal — for which it is seeking the support of government and safety authorities — to voluntarily phase down the use of hydrofluorocarbon (HFC) refrigerants used in household refrigerators and freezers after 2024.
Proposal would phase out use of R-134a, R-410A, and R-407C in chillers
February 4, 2016
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) and the Natural Resources Defense Council (NRDC) issued a joint letter to the U.S. Environmental Protection Agency (EPA) in support of changing the status of certain refrigerants used in liquid chillers under the Significant New Alternatives Policy (SNAP) program effective Jan. 1, 2025.
