What the impending phasedown of HFCs means for contractors is that some of the most used refrigerants will become less available over the next 15 years.
The Refrigeration School Inc. (RSI) in Phoenix, Arizona, in partnership with Clear Channel Outdoor, recently donated and installed an ice machine at Aimee's Animal Sanctuary in Queen Creek, Arizona, to help protect more than 100 special needs animals from severe heat.
Recently, the Underwriters Laboratory (UL) has approved the second edition of its UL 60335-2-89 standard, which includes higher R-290 charge limits that would expand its potential uses in commercial refrigeration.
In a recent public workshop, members of the California Air Resources Board (CARB) discussed how its ambitious HFC emission-reduction program is shaping up.
