Dichlorodifluoromethane (R-12) is a colorless gas popularly known by the genericized brand name Freon (as Freon-12). It is a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant .

Refrigerant R12 or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications. The chemical name of refrigerant R12 is dichlorodifluoromethane and its chemical formula is CCl2F2. This articles describes the properties, advantages, and disadvantages of refrigerant R-12.

Refrigerant R12, commonly known as Freon, is used as a cooling agent. This CFC gas can be found everywhere; in air-conditioning units and other home appliances, industrial chillers, water fountains, cars, medical refrigeration, and even nuclear facilities, to name a few.

2021年5月17日 · Back in the day, that might mean a recharge of Freon, also known as R12 refrigerant. But Freon was shown to deplete the earth’s vital ozone layer. So carmakers were mandated to stop using R12 after the 1994 model year. One current replacement refrigerant is R134a, which serves the same purpose as Freon but is less harmful to the environment.

2024年12月17日 · R-12, also known as dichlorodifluoromethane, is a type of chlorofluorocarbon (CFC) that was widely used as a refrigerant in air conditioning systems and refrigeration appliances. Its chemical formula is CCl2F2, and it has been a standard refrigerant in many household and commercial cooling systems since the 1930s.

2018年12月31日 · R-12 came around and provided consumers and businesses with a safe and cheaper alternative refrigerant. R-12 has a relatively low boiling point at only -29.8° Celsius or -21.64° Fahrenheit. If you compare this to some of the other refrigerants out there such as R-22 (-40.7° C), R-744 (-78.0° C), or R-410A (-48.5° C).

R-12 is subject to U.S. Environmental Protection Agency Clean Air Act Regulations Section 608 in 40 CFR Part 82 regarding refrigerant recycling. The information offered here is for the product as shipped.

2024年12月19日 · Yes, R-12 refrigerant is still available for purchase, but its availability is significantly limited due to regulatory restrictions. The production of R-12 was phased out in the United States and many other countries following the Montreal Protocol, which aimed to reduce substances that deplete the ozone layer.

In this chart, we compare R32 vs R290 vs R134a vs R12 refrigerant, so you have all the basic details when conducting research for repairs and retrofitting.

R12 is a colorless and odorless CFC refrigerant that was phased out of production in 1995 due to its ozone-depleting nature. R12 was utilized in many applications in refrigeration and air conditioning including residential appliances (prior to 1950), automotive air conditioning (prior to 1994), industrial and commercial refrigeration.
