The F-gas review has introduced stricter bans on refrigerants for certain products, and adjusted a sharp phase-down of refrigerants, aiming for near-zero emissions by 2050. Additionally, European institutes are debating restrictions on PFAS, which could further limit refrigerants containing PFAS. These combined regulations may result in very few refrigerant options, likely limiting choices to propane, ammonia, water, and carbon dioxide. Simultaneously, the commission is revising Ecodesign requirements for air-to-air heat pumps, air-to-water, water-to-water heat pumps, and professional refrigeration systems. These new regulations will have to be implemented at the same time when Industry prepares for refrigerant transitions. Refrigerant transitions needs to consider several aspects. First, ...
