Since the phaseout of R-12, R-134a has grown to become the standard refrigerant choice for household appliances, small self-contained refrigeration units, very large chillers, and automotive air conditioning. It is also a component in many refrigerant blends on the market. R-134a is an HFC refrigerant, which requires polyolester (POE) lubricant to be used in the compressor.
