Which refrigerant is specifically addressed by EC Regulations 517/2014?

The refrigerant specifically addressed by EC Regulations 517/2014 is R404A. This regulation aims to reduce the emissions of fluorinated greenhouse gases, which include various refrigerants with high global warming potential. R404A is one of the refrigerants that fall into this category.

R404A is commonly used in commercial refrigeration, and due to its high GWP, it has been targeted by the European Union's legislation to phase down the use of such substances gradually. This regulation encourages the adoption of refrigerants with lower GWP to minimize environmental impact, and R404A's inclusion reflects this effort.

In contrast, while R134A, R22, and R410A are also important refrigerants under scrutiny, they are either not as prominently regulated specific to this regulation or are under different regulatory contexts concerning their emissions and phasing out timelines. Thus, R404A is clearly highlighted for its association with the regulatory framework set by EC Regulations 517/2014.
