After the market introduction of Ururu Sarara in 2013- the first domestic air-conditioner that uses R32 in Europe- Daikin Europe has expanded its product range in domestic units with two more models: the new Daikin Emura and Daikin FTXM. A market pioneer, Daikin concentrates in the design of thermal comfort, solutions that have a minimal environmental impact. Seasonal Efficiency Ratio (SEER) and the cooling agent, however, are the basic parameters for the design of any new model . With these parameters in mind, Daikin introduced in the Japanese market the first air-conditioners that have adopted R32 by the end of 2012, whereas the installation already account to about 2 million. By 2013 the installations had begun in Europe as well.
What is R32
Its chemical name is difluoromethane. Its use has been proved several years ago as an ingredient for the refrigerant R410 (R-410 is a mixture of 50% R-32 and 50% R-125).
Daikin and other manufacturers have determined that the use of R-32 in its purest form, instead of R-410 or other mixtures of refrigerants offer a range of advantages.
Why R-32
Daikin has determined that R-32 is the most suitable refrigerant for air-conditioners. R-32’s GWPC (Global Warming Potential) is just one-third of that of R-410’s. Also, R-32’s superb energy efficiency means that air-conditioners emit fewer greenhouse gases and require less refrigerant volume to operate. As R-32 is not a mixture of various other refrigerants it’s easier to be recycled in the future, which is an additional benefit for the environment.
R-32 has a slight degree of flammability (falls in the 2L category according to ISO817) and can be safely used in the majority of most cooling and heat pumps applications.
Miles ahead of legislation
According to the new European regulation (F gas regulation) that was in effect by the beginning of 2015, all imports of air-conditioners with R-410 will be forbidden as from 2025. Only refrigerants with a GWP lower than 750 will have permission to be imported in Europe from 2025 onwards. Daikin’s R-32 models already comply with this regulation, 10 years ahead of the regulation’s effect date!
