It is used in R-134a air conditioning systems to lubricate the compressor.

How does R134a work in an evaporator?

R134a condenses as it cools, so it then is sent to the evaporator where it is made back into a vapor again. R134a is hydrofluorocarbon (HFC) refrigerant, making it chlorine-free and a greener alternative to earlier air conditioning refrigerants, like R22, that cause ozone depletion.
