    Polyolester oil (POE oil) is a type of wax-free synthetic oils used in refrigeration compressors that is compatible with the refrigerants R-134a, R-410A, and R-12. [1] POE oils are used as a lubricant in systems using the refrigerant HFC-134a when replacing CFC-12 , as these systems traditionally use mineral oil , [ 2 ] which HFC-134a does not ...

    en.wikipedia.org/wiki/Trans-1,3,3,3-tetrafluoro...

    The use of R-134a is being phased out because of its high global warming potential (GWP). HFO-1234ze(E) itself has zero ozone-depletion potential (ODP=0), a very low global warming potential (GWP < 1 ), even lower than CO 2 , and it is classified by ANSI/ASHRAE [ 4 ] as class A2L refrigerant (lower flammability (see below) and lower toxicity).
