Carrier, meeting the challenge of regulatory changes
The challenge raised by the European Union’s F-gas Regulation means the entire industry must move to a new generation of refrigerants, that will not only protect the ozone layer but also have a very low global warming impact. Carrier is facing this challenge head on. The European F-gas Regulation 2014
The 2014 revision of the regulation introduced bans for certain equipment using hydrofluorocarbon (HFC) chemicals and a phase down scheme for HFCs placed on the European market: • Equipment bans target refrigeration applications and very low capacity air to air conditioners (residential). There are no specific bans on liquid chillers and hot water heat pumps using R-134a, R-407C and R-410A refrigerants. • The phase down is a step-by-step approach to lower the CO2 equivalent in the HFCs that are placed on the market are gradually reduced through the allocation of quotas by the European Commission to producers and importers of bulk HFCs and importers of HFCs contained in pre-charged equipment. As a result of the phase down, high Global Warming Power (GWP) HFC consumption will be drastically reduced in 2030. European Union’s targets HFC consumption related to CO2 equivalent
Carrier’s solution: PUREtec™
Carrier has been working over the past years on selecting the right refrigerant for the future and has now taken the lead in introducing the next generation of refrigerants on screw compressor chillers and heat pumps : PUREtec . With PUREtec, Carrier offers a range of new customized solutions using a refrigerant with zero impact on the ozone layer and nearly zero global warming potential: HFO R-1234ze.
PUREtec extensive research program
