The Most Common Refrigerants Used in Air Conditioning Systems
Entrance
Air conditioning systems, an essential part of our daily comfort, operate efficiently using the refrigerants they use. However, not every air conditioning system is compatible with every gas. So, which gases are most commonly used? What are their properties?
In this article, we examine in detail the most commonly used refrigerants in air conditioning systems and their properties.
1. R-410A: High Performance, Less Environmental Impact
R-410A has been one of the most preferred gases in split air conditioning systems for many years.
✅ Features:
✔️ Mixed gas (R-32 + R-125)
✔️ Does not harm the ozone layer (ODP=0)
✔️ Medium GWP: 2088
✅ Application areas:
✔️ Home type air conditioners
✔️ Light commercial VRF systems
2. R-32: New Generation and Environmentally Friendly Option
R-32, which has become preferred over R-410A in recent years, stands out with its lower GWP value and less gas consumption.
✅ Features:
✔️ Single component, 100% pure gas
✔️ GWP value 675
✔️ Higher cooling efficiency
✅ Application areas:
✔️ New generation inverter air conditioners
✔️ Energy efficient split systems
3. R-22: Gas of the Past, Problem of Today
R-22, once widely used, is now banned in many countries because it damages the ozone layer .
✅ Features:
✔️ It is classified as HCFC
✔️ It is harmful to the environment because ODP > 0
✔️ R-410A or R-32 is used instead
✅ Attention:
✔️ Can be found in existing systems, but renewal is recommended
4. R-290 (Propane): The Natural and Efficient Option
R-290 is a natural hydrocarbon-based refrigerant gas that stands out for its low environmental impact.
✅ Features:
✔️ GWP: 3
✔️ High energy efficiency
✔️ It should be used with caution because it is classified as a flammable gas.
✅ Application areas:
✔️ Portable air conditioners
✔️ Small commercial refrigerators
Conclusion
The refrigerants used in air conditioning systems directly impact the device's performance, environmental impact, and energy consumption. While newer systems are emphasizing environmentally friendly options like R-32, older systems still use R-22.
