What Is Refrigerant Charging?

Freon refrigerants, referred to as CFCs. It mainly includes R11, R12, R113, R114, R115, R500, R502, etc. Due to its damaging effect on the ozone layer and the largest, it is listed as a controlled substance by the Montreal Protocol.

Freon refrigerant

Right!

Freon refrigerants, referred to as CFCs. It mainly includes R11, R12, R113, R114, R115, R500, R502, etc.

One is chlorofluorocarbon products

The second is hydrochlorofluorocarbons: HCFCs for short. It mainly includes R22, R123, R141b, R142b, etc. The ozone layer destruction coefficient is only a few percent of R11. Therefore, HCFCs are currently regarded as the most important transitional substitutes for CFCs. In the Montreal Protocol, R22 is limited to 2020 and R123 is limited to 2030.

The third is hydrofluorocarbons: referred to as HFCs. It mainly includes R134A (replacement refrigerant for R12), R125, R32, R407C, R410A (replacement refrigerant for R22), R152, etc. The ozone layer destruction coefficient is 0, but the potential for climate warming is high. The Montreal Protocol does not stipulate its use period, and it is characterized as a greenhouse gas in the Kyoto Protocol of the United Nations Framework Convention on Climate Change.

Fourth, mixed refrigerant

Experts said: All the refrigerants we currently use are Freon products, and non-Freon refrigerants have not been developed so far. The government has banned the first type of chlorofluorocarbon products. For hydrochlorofluorocarbon products and hydrofluorocarbon refrigerants, there is still a long period of use. Therefore, consumers should never talk about "fluorine" discoloration.
