There has been significant movement at the state and federal levels recently regarding refrigerant regulations, and at a recent webinar, experts from Emerson and AHRI discussed the impacts of these impending HFC phasedown rules. They also discussed the changes that need to be made to building codes and standards before alternative refrigerants — many of which have slightly different flammability characteristics — may be used in stationary air conditioning and commercial refrigeration equipment.
This is shaping up to be a pivotal year in terms of refrigerant regulations, and keeping up with all the latest developments will be crucial for HVACR contractors.
