Gas Charging in single door Refrigerator, R-134a Replace Hydrocarbons.

R134a (or HFC-134a) is a non-flammable hydrofluorocarbon refrigerant that was introduced to commercial and industrial applications as an alternative to the R-12 CFC refrigerant. R134a performs similarly to R-12, making it an easy-to-use replacement, and is relatively safe to use as it has an ASHRAE classification of A1. R134a is also known as a tetrafluorethane (CH2FCF3) since it consists of carbon, hydrogen and carbon. One of the positives of R134a is that it doesn’t contain chlorine, making it significantly less toxic than R-12.
