Explore global refrigerant regulations shaping HVAC products, with insights on compliance, phase-down timelines, and eco-friendly alternatives worldwide. Stay ahead of environmental laws affecting refrigerants like HFCs and HCFCs, and ensure your HVAC systems meet international compliance standards.
As global climate change concerns rise and environmental regulations become stricter, the HVAC industry must transition toward more sustainable, low-GWP refrigerants. Refrigerants play a vital role in heating, ventilation, and air conditioning systems, but many traditional options significantly contribute to global warming. This guide outlines essential international refrigerant regulations, including the Kigali Amendment, F-Gas Regulation (EU), and the AIM Act (USA), focusing on phase-down schedules and compliance requirements.
These regulations and sustainable refrigerant practices are also directly applicable to Telecom Cabinets, Energy Storage Units, and Thermal Management Systems, where efficient temperature control and regulatory compliance are equally critical.
Phases out ozone-depleting substances (ODS) like CFCs and HCFCs.
Targets hydrofluorocarbons (HFCs) with high global warming potential (GWP), including R134a (GWP = 1430)
R134a (prohibited in new equipment since 2022 under F-Gas Regulation 517/2014)
R513A (GWP = 631), R450A (GWP = 547), R1234yf (GWP = 4)
Strict GWP limits: Max GWP = 750 for stationary refrigeration.
R134a is allowed but restricted in specific sectors under EPA SNAP Program (e.g., banned in new light-duty vehicles).
R454B (GWP = 466), R32 (GWP = 675), R1234ze (GWP = 7)
State-level variations (e.g., California adopts stricter rules).
R134a in new commercial refrigeration (phased out by 2025).
R513A, R448A (GWP = 1273, transitional).
R134a is allowed but taxed under the HFC phase-down schedule
R452B (GWP = 698), R455A (GWP = 146)
R134a is allowed but discouraged; taxes apply to high-GWP refrigerants.
R32, R1234yf.
R134a is allowed but subject to HFC phase-down under the Kigali Amendment (starts 2024).
R134a is widely used but will phase down under the Kigali Amendment (starts 2028)
R454C (GWP = 148), R152a (GWP = 124)
R134a is allowed with minimal restrictions
Growing adoption of alternatives like R513A for sustainability.
R134a is allowed but phased down in some countries (e.g., South Africa)
R600a (GWP = 3), R290.
