Things To Be Aware Of When Considering R-22 Replacement Refrigerants
If your air conditioning or refrigerator just won’t keep it’s cool anymore, chances are you’re in need of a refrigerant replacement. Many people still depend on machines that use R-22, which is a hydrochlorofluorocarbon and powerful greenhouse gas.
Much like Freon, which came before it, R-22 has been phased out all across the US because of the threat it poses to the environment. So you will likely have to find a R-22 refrigerant replacement. There are a lot to choose from, but after you read this article you will be able to make that choice with more confidence.
What Does A Refrigerant Do?
Refrigerants are responsible for transitioning between gaseous and liquid states during the cooling process. These phase changes are key to how the thermodynamics of modern A/Cs and coolers work.
The country’s former favorite refrigerants, Freon and R-22, were both classified as POE oils, which stands for polyolester. If your system started off using a POE oil then it’s highly advisable to stick with a POE replacement. These POE oils tend to be named like “R-some number”. This is something that DuPont started doing which the industry just picked up and now maintains as the standard. But some oils are better than others.
What Should R-22 Be Replaced With?
While there are over a dozen options for R-22 replacements there are two main candidates. They are: R-407c and R-438 (MO99).
- R-407c is a blend of three different hydrofluorocarbons. Its biggest con is that it requires a more thorough changeout of oil when it’s being used as a replacement for an existing refrigerant. Its biggest pro is that its capacity is roughly equivalent to R-22.
- R-438 (MO99) has less capacity to lower temperature, by comparison. However, it is easier to use as a replacement, and can even be used in systems that depend on mineral oil. But be warned! You should never just pour one refrigerant on top of another. And it’s illegal in most parts of the country to work with refrigerant without proper licensing.
