R404A is an HFC blend that is widely used
in low and medium temperature refrigeration applications, such as those used in
commercial refrigeration. Whilst it has become the widely accepted alternative
to CFC R502, R404A is coming under greater scrutiny due to its high Global
Warming Potential, leading to an increased focus on lower GWP alternatives such
as R407C, R417A and R422D.
