The European Union sets very stringent environmental standards for the use and handling of air conditioning equipment with fluorinated greenhouse gases. For measuring how each affects the global warming gas, and therefore limit or regulate use.
Currently R410A gas remains the most widely used. But nevertheless, R-32 has the advantage of having a PCA up 3 times lower Y, also, It requires less amount of gas (near a 30% less) to function efficiently. For these reasons it is likely that its presence in the market will increase in the coming years.
In this context, last 8 from December to 2018 It approved a Royal Decree-Law 20/2018 It is establishing a new classification of gases depending on their toxicity and flammability. The R-32 was included within the new group A2L (low toxicity and low flammability), so that, Thanks to this modification rules, certified installers who have the license ITE (RITE) and they can do with this gas installations.
HFC-32 or R-32 widely it is the refrigerant will replace R410A which is the most widely used until now.
The R32 has no impact on the destruction of the ozone layer of the planet and, also, It represents a much lower impact in terms of global warming refrigerants previously manufactured; its index of Global Warming Potential is up to three times less than their predecessors.
R32 is a pure gas, so recycling and treatment is much easier than those used today in large com R410A, which they are a mixture of several gases. The full transition should take place until 2030, but every manufacturer like Mitsubishi Electric are adopting more and more models using these new less polluting gases.
The complete transition, It must be made to the year 2030. All industry manufacturers are already adapting their models to work effectively hand new cleaner and more environmentally friendly gases with.
