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.
The cyclical pattern of change in refrigerants is linked directly to our growing understanding of the unintended consequences of refrigerant interactions with our atmosphere, coupled with advancements in technology and shifts in societal values toward sustainability. One only needs to look at the evolution of refrigerants to see these trends at play.
Topics include toxicity, flammability, and higher pressures
February 1, 2016
With the advancing worldwide phaseout of hydrochlorofluorocarbons (HCFCs), the United Nations Environmental Programme (UNEP’s) OzonAction Division of Technology has produced a series of factsheets on the safe use of the new alternative refrigerants.
Offers a quicker pull-down time compared to other refrigerants
October 19, 2015
MTL Cool said its new line of display cases using R-441A offers improved efficiency compared to units running on either R-134a or R-290 (propane), with test data showing that the first of this line, the new NRC2 system, runs on a 17 percent lower charge and requires 17 percent less energy compared to units running on R-290.
