Air conditioners are devices that help maintain comfortable indoor temperatures, mostly during the very hot summers. Integral to their operation is a chemical compound called refrigerant that changes its state from liquid to gas and vice versa as it cools the air. The different types of refrigerant in AC systems can help homeowners make informed decisions concerning maintaining or replacing their air conditioning units.
What Is the Refrigerant in an Air Conditioner?
An air conditioner refrigerant is a specialized liquid that absorbs heat from the indoor environment and releases it outside, facilitating the cooling process. This essential component is crucial for the efficient operation of your AC unit. To gain a deeper understanding of its function and importance, read "What Is AC Refrigerant & How Does it Work?" Now, how effective an AC system is and how much damage it causes to the environment greatly depends on the type of refrigerant being used.
4 Main Types of Refrigerants
1. R-22 Refrigerant
Known by the trade name Freon, R-22 has been used in most residential air conditioning systems. However, with an ODP (ozone depletion potential) of 0.05, it has been phased out under the Clean Air Act. Although R-22 is still available to service older systems, it is becoming very expensive and scarce.
2. R-32 Refrigerant
R-32 is also a refrigerant with a lower GWP (global warming potential) than R-22 and offers high energy efficiency. Because it is easier to handle, R-32 is becoming the choice for new home AC systems.
3. R-454B Refrigerant
R-454B is a new refrigerant formulated to be an alternative to R-410A with radically much more enhanced GWP and, hence, sustainability. The R-454B offers great energy efficiency and is likely to take a big market share with increasing regulatory standards for environmentally safer refrigerants.
4. R-410A Refrigerant
Known by the brand name Puron, R-410A is a hydrofluorocarbon refrigerant used in many newer home AC systems. It does not have an ODP and provides better energy efficiency than R-22. On the other hand, it has a higher GWP than new-generation refrigerants like R-32 and R-454B.
How to Tell Which Refrigerant to Use
You can determine the right type of home AC refrigerant by simply checking the nameplate or user's manual of your unit, which will show, in most instances, the kind of refrigerant required. If doubts persist, consult a professional HVAC company in Atlanta to recommend a compatible and efficient solution for you.
