R-134a
R-134a is developed to replace CFCs and HCFCs in several refrigeration and air conditioning systems.
It is non-flammable and used with polyol ester(POE) and PAGs lubricants which are available in a wide viscosity range.
It can be applied in refrigeration applications including commercial refrigeration, automotive air conditioning, and home refrigerator and air conditioning, etc.
