R134a as refrigeration using the most widely in the low and middle temperature environmental protection, due to its good comprehensive performance, becomes a very effective and security replacement of CFC-12, mainly apply to the most areas which using R12 refrigeration.

R134a does not contain chlorine atoms, no damages to the ozone layer, with good safety performance (no flammable, no explosions, non-toxic, non-irritant, no corrosion).
