As a consequence of the F-Gas Regulation provisions regarding the HFC phase-down and the equipment use restrictions, producers and equipment manufacturers have worked to introduce a number of lower GWP alternatives, by blending HFCs with HFO-1234yf or HFO-1234ze. Blends compositions have to be fine tuned in order to meet technical and energy efficiency performances expected for each kind of application.
The EU Commission has published in November 2015 four new implementing Regulations to the F-Gas Regulation EC 517 (2014) relevant to air conditioning, refrigeration, heat pump and electrical equipment sectors
TFA (trifluoroacetic acid and its salts) is breakdown product of some fluorocarbons, is naturally occurring in the environment and resistant to further degradation (breakdown). This EFCTC issues newsletter is intended to provide an easy to understand summary of the 'TFA story' and provides links to more detailed supporting information.
The U.S. Air Conditioning, Heating and Refrigeration Institute (AHRI) has launched a new research project to evaluate the energy produced by potential ignition sources in residential applications compared to the minimum ignition energies of A2L refrigerants.
Having already been successfully introduced as blowing agent in different insulating polyurethane foam applications, for instance in Cold Storage Rooms or in Spray foams, HFO-1233zdE was named the winner of the 2015 Polyurethane Innovation Award by the American CPI (Center for the Polyurethanes Industry).
