If you’re confused about the difference between R134a and R12, you’re not alone. Many people don’t know that there are two different types of refrigerant, and they often use the terms interchangeably. But there are some important differences between R134a and R12 that you should be aware of. Here’s a quick rundown of the main differences between these two types of refrigerant.
What is R12?
R12 is a refrigerant that was commonly used in vehicles before the 1990s. It is also known as Freon. R12 works by absorbing heat from the air inside the vehicle and releasing it outside. This process helps to keep the inside of the vehicle cool. R12 is a chlorofluorocarbon, which means that it contains chlorine and fluorine. This makes it harmful to the environment. R12 is being phased out and is being replaced by more environmentally friendly refrigerants.
What is the difference between R134a and R12?
R134a and R12 are two different types of refrigerants. R134a is a hydrofluorocarbon (HFC) while R12 is a chlorofluorocarbon (CFC). While they are both used in air conditioners and refrigerators, they work in different ways.
R134a works by absorbing heat from the air and releasing it outside. It does not require a compressor like R12 does. This makes it more efficient and less expensive to operate.
R12, on the other hand, works by circulating a gas called Freon through the air conditioner. The Freon absorbs the heat from the air and then releases it outside. This process requires a compressor, which makes it more expensive to operate.
R134a is the more environmentally friendly option because it does not contain chlorine. R12 is being phased out because of its harmful effects on the environment.
Pros:
R134a is a much more environmentally friendly refrigerant than R12. It does not deplete the ozone layer and has a global warming potential of just 1,430. In contrast, R12 has a GWP of 10,900. This means that R134a contributes around 14% of the greenhouse effect of R12.
R134a is also much more efficient than R12. It has a higher cooling capacity and a lower pressure than R12, which means that it can cool your car more effectively.
R134a is also less likely to leak than R12. It is a “non-azeotropic” refrigerant, which means that it does not separate into different components when it is under pressure. This makes it less likely to leak from your car’s AC system.
R134a is also cheaper than R12. It is a “generic” refrigerant, which means that it is not patented by any company. This makes it much less expensive to produce and to buy.
Cons:
There are a few cons to using R134a that should be considered. First, it is a synthetic gas, which means it can be more expensive than some of the other options. Second, it is not as efficient as some of the other options, so it may not be the best choice for those who are looking to save money on their cooling costs. Finally, it is not as environmentally friendly as some of the other options, so it may not be the best choice for those who are concerned about their impact on the environment.
Pros:
R134a is a much more environmentally friendly refrigerant than R12. It does not deplete the ozone layer, and it has a very low global warming potential. This means that it is much better for the environment than R12, and it is the refrigerant of choice for many new cars and refrigerators.
R134a is also a much cheaper refrigerant than R12. It is widely available, and does not require special equipment or training to use. This makes it a great choice for budget-conscious consumers.
R134a is also a much more efficient refrigerant than R12. It cools more quickly and evenly, and does not cause as much ice build-up. This makes it a great choice for people who want to keep their food and drinks cold, but do not want to have to deal with the hassle of constantly defrosting their refrigerator.
Cons:
While R134a may be the more environmentally friendly option, it does have some cons. For one, it is not as effective as R12 in cooling, so your AC may not work as well. Additionally, R134a is more expensive than R12, so you may have to pay more to get your AC unit serviced.
Chemistry
R134a and R12 are both refrigerants. They are both used in air conditioners and refrigerators. R134a is a newer refrigerant, while R12 is an older refrigerant. R134a is more efficient than R12 and does not contribute to ozone depletion.
Ozone Depletion Potential (ODP)
R134a is a hydrofluorocarbon (HFC) that does not contain chlorine. Because it does not contain chlorine, it does not deplete the ozone layer. R12, on the other hand, is a chlorofluorocarbon (CFC) that does contain chlorine. When CFCs are released into the atmosphere, the chlorine reacts with ultraviolet light and breaks down ozone molecules. This process depletes the ozone layer, which protects the earth from harmful ultraviolet radiation.
Global Warming Potential (GWP)
R134a is a hydrofluorocarbon (HFC) that does not deplete the ozone layer and has a very low global warming potential (GWP). In fact, its GWP is only about 1/4 that of carbon dioxide (CO2). That means that for each pound of R134a that is released into the atmosphere, only about 1/4 pound of CO2 is produced.
In contrast, R12 is a chlorofluorocarbon (CFC) that depletes the ozone layer. It also has a very high GWP. In fact, its GWP is about 3,500 times that of CO2. That means that for each pound of R12 that is released into the atmosphere, about 3,500 pounds of CO2 is produced.
So, if you are concerned about global warming, R134a is the better choice.
Oils
There are a few different types of oils that can be used in air conditioners, and they each have their own benefits and drawbacks. The most common type of oil used in air conditioners is R134a, but there is also R12 and a few others.
R134a is the most common type of oil used in air conditioners because it is the most efficient. It is also the most expensive, but it is worth the cost because it will save you money in the long run.
R12 is another type of oil that can be used in air conditioners, but it is not as efficient as R134a. It is also more expensive, but it is not as effective.
There are a few other types of oils that can be used in air conditioners, but they are not as common. These oils include R22, R410a, and R407c.
