Back at the end of the 20th century, engineers found that R-12 is an eco-enemy refrigerant as a result, a new refrigerating gas was developed in the lab called R134a. R-134a is a type of A/C refrigerating gas used in the A/C system. Related Post: How To Recharge Car Air ConditionerĢ. An environmentally friendly refrigeration system utilizes refrigeration gas with low climate impact and minimizes the release of refrigerating gas into the atmosphere, helping to reduce its impact on the environment. So, from 1994, r-12 refrigerating gas was banned in new cars, and R134a refrigerant started to use in car A/C systems. Luckily they found an ozone-friendly refrigerating gas R134a, which contributes less to global warming as compared to r-12 refrigeration gas. R-12 is still in use in antique and old vehicle types, but such older vehicles are very rare in number now. Its climate impact is 2400, which is very high compared to carbon dioxide (CO₂), which has a climate impact of one according to 2021 federal and standard protocol. This was the reason scientists were compelled to find out the solution to rapidly increasing global warming. It was perfectly doing its job until scientists discovered that it is responsible for the rapid deplete the ozone layer. It is a colorless, odorless, non-explosive, and non-flammable gas. It is best for cars manufactured before 1995, R-12 refrigerating gas was the standard for automotive air conditioning. R-12 is a laboratory-man-made refrigerant it was widely used in automobile AC systems. R-12 has the molecules of chlorine, fluorine, and carbon it is also called chlorofluorocarbon (CFC). Its chemical name is dichlorodifluoromethane. R-12 refrigerant also known as Freon, Freon-12, R-12, and CFC-12 is a kind of freon A/C refrigerating gas.

That is why it is illegal and prohibited in air conditioning units to vent car A/C refrigerating gas into the atmosphere. Car refrigerating gas is volatile, flammable, and toxic, and contributes to ozone depletion, which causes global warming. In the end, again the refrigerating gas is sent back to the compressor, where it becomes liquid. A coil of tubes acts as an evaporator in car refrigeration to cold the air. The cooled A/C refrigerating gas is then auto allowed to expand in the evaporator, where the evaporator works to convert liquid into a gas and absorbs heat in the surrounding area of the car or truck interior. Car’s air conditioning system converts the refrigerating gas phases from liquid to gas and back again in A/C systems.įirstly, the A/C refrigerating gas is compressed by the compressor and becomes liquid, then it is cooled off in the condenser. Refrigerant is a volatile gas used in the refrigeration cycle of an A/C system.
