Examining different refrigerant classifications, the differences between refrigerants, and the influences driving the shift away from traditional refrigerants to A2L refrigerants.

Manufacturers are offering low-GWP refrigerant alternatives, as EPA is proposing a 700 GWP limit for most new comfort cooling chillers starting in 2025.

There are numerous federal regulations, state building codes, and safety standards that are supporting the transition to low-GWP refrigerants. Copeland recently outlined some of these issues in a webinar.

Europe is enacting new stricter refrigerant regulations, in response to PFAS and calls for a faster HFC phasedown.

EPA finalized SNAP Rule 25 and proposed SNAP Rule 26, both of which allow the use of A2L refrigerants in some new air conditioning and refrigeration equipment.

EPA proposed a new rule as part of its efforts to phase down the use of high-GWP HFCs. HVAC manufacturers expressed concern about some of the provisions in the new rule, including training, GWP limits, compliance deadlines, and sell-through periods.

California will fund energy-efficient and climate-friendly refrigeration and freezer equipment in corner stores, small businesses, and food donation programs in low-income or low-food access.

As an industry, we have rolled with efficiency changes in the past, even when the bureaucrats making the rules lack an understanding of the impact simple things like warehousing, transportation, and installations have on the industry. Or maybe they do not care.

A steep cut in HFC production occurs next year, and it appears that not enough HFCs are being recovered and reclaimed to meet the demand for existing and new HVACR equipment. Just how dire is this situation?
