Window unit AC: Cost to drain right vs scrapping gain (number help)

The primary difference between R22 and R134 refrigerant is what each contains. R22 refrigerant is a single hydrochlorofluorocarbon (HCFC) compound that contains hydrogen, chlorine, fluorine and carbon. R134 refrigerant is a single hydrofluorocarbon (HFC) refrigerant that contains hydrogen, fluorine and carbon. It does not contain chlorine, which makes it more environmentally-friendly than R22 refrigerant.


Environmental Impact



R22 is less stable than R134 because, when the hydrogen compound breaks down in the atmosphere, it releases chlorine before it reaches the stratosphere. The chlorine then reacts with the oxygen molecules in the ozone to create new molecules that result in ozone depletion. Because of this, R22 is considered a greenhouse gas, and the EPA is working to phase it out in the United States before 2030. Because it doesn’t contain chlorine, R134 is considered safer to use and was designed to replace chlorine-containing refrigerants, such as R22, because it is less damaging to the ozone.
