Having its usage banned in air conditioning systems and many other refrigeration applications due to the danger it poses to the ozone layer, several companies that are affected by the R22 legislation would possess a policy to identify specific recommended alternatives. If you’re also affected by this new legislation, then you’ve come to the right place. Generally, the alternative that’s selected is usually dependent on the business unit level as well as the business’ energy efficiency requirements. In this post, we’re going to consider some of the recommended alternatives to the R22 refrigerant. Let’s take a look!
- R140a. This refrigerant is commonly used in industrial refrigeration, residential air conditioning, industrial air conditioning as well as commercial centrifugal compressors.
- R134A. This refrigerant is commonly used in domestic refrigeration, commercial refrigeration, transport refrigeration, residential air conditioning, commercial centrifugal compressors and mobile air conditioning.
- R407C. This is commonly incorporated in industrial refrigeration, residential air conditioning and commercial air conditioning.
- R407A. This type of gas is commonly incorporated in commercial refrigeration, plug ins as well as vending machines.
- MO99 ( R438A). This gas type is common applied in commercial refrigeration, plug ins, vending machines, industrial refrigeration as well as residential air conditioning.
- RS-44b. This is commonly used in all refrigeration systems.
These R22 alternatives are all believed to be environmental friendly having little to no impact on the ozone layer. However, one drawback possessed by of these alternatives is when POE oil is incorporated. This can result in excess moisture which causes acid build up inside the refrigerant lines. What’s more? These refrigerant alternatives also work at a higher pressure which means that it may cause more wear and tear on components.
