For HVAC refrigerants, the changes keep coming fast and furious at a time when the global demand continues to grow apace. Changes implemented via the EPA’s Significant New Alternatives Policy (SNAP) program, combined with the continued phase out of R-22, will lead contractors to seek out opportunities to gain experience with the use of new low-GWP refrigerants.
The MiniReStoraMOD is a high-rise fan coil designed for retrofit and replacement jobs. Developed to be minimally invasive, it enables fast and easy replacement for hospitality, multifamily, and higher education applications.
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has published research project AHRI 8018: Review of Refrigerant Management Programs. This project examined refrigerant management and recycling programs implemented in key regions of the world, evaluated their effectiveness, and determined best practices.
In October 2014, the EPA announced its final phasedown schedule regarding the production and importation of HCFC-22. The order called for an immediate drop from 51 million pounds allowed in 2014 to 22 million pounds in 2015, 18 million pounds in 2016, 13 million pounds in 2017, 9 million pounds in 2018, and 4 million pounds in 2019. No new or imported R-22 will be allowed in the U.S. on or after Jan. 1, 2020.
