Most HVACR technicians will need to raise their levels of safety consciousness when servicing equipment using flammable hydrocarbon (HC) refrigerants, such as R-290 (propane) or R-600a (isobutane), and the first place many technicians are likely to encounter these HCs will be in smaller kitchen equipment, such as reach-in coolers.
Residential and commercial ‘worst-case scenarios’ included in A2L research

The Air-Conditioning, Heating, and Refrigeration Technology Institute (AHRTI) — the research arm of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) — released the first research report as part of its ongoing testing of flammable refrigerants, many of which were identified as possible replacements to high-GWP (global warming-potential) hydrofluorocarbons (HFCs) that will be phased down under the Montreal Protocol.
First-ever specialized course is for light rail system that operates in 100-degree heat
July 5, 2017
The Refrigeration School, Inc. (RSI), Phoenix, Arizona, has announced a first of its kind partnership with Valley Metro Rail. The partnership provides specialized HVACR training for Valley Metro maintenance technicians to continue their career and technical development. Valley Metro Rail serves an average of 50,000 riders a day and operates along 26 miles in Phoenix, Tempe, and Mesa.
We all know that these are interesting times in Refrigerationland. CFCs are history, HCFCs are on their way out, and HFCs are being scrutinized and phased down; dozens of new refrigerants are in the works or have already arrived on the scene; naturals are poised to claim a bigger share of the market; we’re in the Paris agreement and then we’re out, and no one knows what that might mean for the Kigali Amendment; and the Department of Energy is always lurking about, ramping up efficiency standards.
