HRAI’s emerging technologies committee has been assessing the implications of flammable refrigerants on the HVACR industry in Canada.  The analysis includes consideration of training needs, public awareness, research and the need for advocacy in this area.  HRAI will be striking a special task team to review these matters further and will work with other industry associations, as necessary.

North American Technician Excellence (NATE) is developing an exam for flammable refrigerants and the Air Conditioning Contractors of America (ACCA) has released a technical bulletin onFlammable A3 Refrigerants, as reported last week in the ACHR News.

The ACCA document addresses technician challenges and focuses on ASHRAE designated A3 refrigerants, commonly found in walk-in coolers, merchandisers, service cases, vending machines, and more. It covers safety, installation, start-up, maintenance, parts replacement, leak checking, transporting units, decommissioning, etc. It mentions R-290 (propane), R-441A, R-600a (isobutene), and R-1270, but applies to all A3 refrigerants.

ACHR noted reviewing the bulletin was important for safety, but also because it represents a business opportunity. Retailers are reportedly having difficulty finding qualified service technicians for the equipment mentioned. The bulletin is called Air Conditioning and Refrigeration Systems Using Flammable A3 Refrigerants and is a free PDF download for ACCA members. Further guidance on this is forthcoming from HRAI, ACCA and other partners.  Stay tuned.
