The US Air Conditioning, Heating and Refrigeration Institute (AHRI) flammable refrigerants subcommittee, ASHRAE, and the US Department of Energy (DOE) are supporting a collaborative effort to fund research about mildly flammable (ASHRAE class A2L) refrigerants, such as HFC-32, HFO-1234yf or HFO-1234ze(E), in order to allow their safe use.
Over the past months, different interpretations have circulated on the definition of a “One-Component Foam” (OCF). As OCF is generally placed on the market in cans with a content of ≤ 1000 ml, the latter has been interpreted as a volume limit. It has been assumed by some that products fulfilling the definition of OCF in the F-Gas Regulation, but placed on the market in larger dispensing units, would not be covered by the ban in Annex III, point 8.
As part of an EU funded project, FRISBEE (Food Refrigeration Innovations for Safety, consumer Benefit, Environmental impact and Energy optimization along cold chain in Europe), supercooling and superchilling tests have demonstrated the potential to enable safe, high quality and long term storage of food without detrimental food quality effects for the consumer.
In a paper published in ACR News – April 2016, addressing the signification of “chemical” or “natural” refrigerants, a British Professor concludes that “the term 'natural' applied to refrigerants is an ideological obfuscation.
Refrigeration and Air Conditioning Equipments for the Rio 2016 Olympics will all be based on R-410A solutions in all 12 new sports arenas and auxiliary facilities in both Barra and Deodoro Olympic Parks.
