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.

2021年5月17日 · If you have a classic car with air conditioning and it hasn’t been upgraded lately, it probably still has R12 refrigerant in the system. While it can no longer be manufactured, there is a surprising amount of Freon still available as new old stock (NOS). Here’s how that happened.

2018年5月7日 · When used in refrigerator and A/C systems, R12 cooled incredibly well. And it was safe—neither poisonous to breathe, nor flammable. In fact, R12 was used for many years as a propellant in a variety of aerosol products and sprayed directly into the air, and it is closely related to the halon used in fire extinguishers.

2018年12月5日 · R-12 was one of the first refrigerants that checked all of the boxes. It was efficient. It was safe. It was non-flammable. It didn’t require immense operating pressure. All of these factors caused the amount of use of R-12 and other CFC/HCFCs to …

2021年6月12日 · R12 and R134a are older types of refrigerants that are considered to be dangerous to the environment today. R12 is highly destructive of the ozone layer, and R134a is over 1,000 times more dangerous in terms of global warming than carbon dioxide.

2024年10月1日 · The R12 ban poses significant challenges to the heating, ventilation, and air conditioning (HVAC) industry. The phase-out of R12 has created a shortage of skilled technicians and equipment capable of handling the new refrigerants.

2024年3月10日 · R12, also known as dichlorodifluoromethane, is banned due to its harmful effects on the ozone layer. As a chlorofluorocarbon (CFC), R12 depletes the ozone layer, allowing more harmful ultraviolet radiation to reach the Earth’s surface.

2018年12月31日 · First and foremost, you should know that R-12 has been completely phased out in the United States and across the world. This refrigerant was phased out due to it’s Ozone Depletion Potential or ODP.

1) Safe properties: Refrigerant R12 is nontoxic, nonflammable, and non-explosive. This makes it highly popular for the domestic as well as the commercial applications. 2) Stability: R12 is highly stable chlorofluorocarbon and it does not disintegrate even under the …

2018年12月31日 · R-12 was the the ‘mother’ of all modern day refrigerants that we see and use everyday in today’s world. Without it, the world would look very different. In this article we’re going to take a brief look at where R-12 came from, how it …
