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.
SensoTech’s LiquiSonic® analyzer allows for precision measurement of oil concentration in refrigerant to ensure the optimum ratio of oil and refrigerant. According to SensoTech, the LiquiSonic sensors use ultrasonic technology to continuously and directly measure the oil concentration.
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.
The refrigeration industry certainly takes its share of heat from the scientific research community, and it can be easy to feel as if we’re being ganged up on. But the good news is that we’ve got some scientists and researchers working on our side, too.
The U.S. Department of Commerce has announced an affirmative preliminary determination in its antidumping duty investigation of imports of HFC refrigerants from China. This encompasses both blends and single-component HFCs.
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.
ComStar International is introducing two new refrigerants. RS-44B (R-453A) is a low-global warming potential (GWP), energy-saving HFC refrigerant that replaces R-22 in a/c and refrigeration applications without an oil or component change.
Refrigeration contractors are keenly aware of the value of the maintenance they perform for their grocery store and supermarket clients, but, in some cases, they may find themselves working with clients who underestimate it.
