The HVACR industry must understand that the HFC “phasedown” is not the same as the “phaseout” that our industry experienced for CFCs and HCFCs.

Manufacturers have created a number of low-GWP solutions that are designed to have similar (or better) efficiencies and capacities than the refrigerants they are intended to replace.

CARB is proposing a GWP limit of 150 for new stationary refrigeration systems containing more than 50 pounds of refrigerant, starting on Jan. 1, 2022.

The big debate in the HVACR industry right now is which refrigerant(s) will be chosen to replace R-410A in many types of comfort cooling equipment.

The refrigerant regulatory landscape is changing in the U.S., leaving many scrambling to figure out which lower-GWP solution will work best.

At the AHR Expo, Emerson held several seminars on the topic of current and future refrigerant regulations in the U.S. The information was timely.

The California Air Resources Board (CARB) held a public workshop in January to discuss its proposals for reducing high-GWP HFCs.

The AHR Expo is the marquee event for the refrigerants industry, and Chemours cherished the opportunity to connect with customers there.

Since many low-GWP refrigerants are flammable, changes must be made to building codes and standards before they will be acceptable in HVACR equipment.
