If you're considering installing a split air conditioner or replacing the gas in your unit, you've probably come across two common names: R32 and R410A.
But which of these gases is best? Which offers better performance, savings, and a lower environmental impact?
In this article, we'll explain the main differences between them in simple terms to help you make the best choice.
What are refrigerant gases?
Refrigerant gases are substances responsible for absorbing and releasing heat within refrigeration and air conditioning systems—it's thanks to them that the air conditioner can cool the room.
With advances in technology and environmental concerns, new formulas have been developed to replace older gases, such as R22, which were damaging to the ozone layer.
Today, the main gases used in split systems are R32 and R410A.
R410A Gas: Efficiency and Safety
R410A gas has long been the standard in the air conditioning market.
It is a blend of two gases (R32 and R125) and is ozone-friendly, offering good energy efficiency and thermal stability.
Advantages of R410A:
It is non-flammable;
It offers good performance and operational safety;
It is widely used and readily available.
Disadvantages:
Its Global Warming Potential (GWP) is higher, meaning it contributes more to global warming;
Recharging must be done with a balanced mixture, which requires specific equipment;
The gas cannot be easily reused, which generates more waste.
R32 Gas: The New Sustainable Standard
R32 is the most modern and sustainable gas currently used in air conditioning systems. It was developed as a more efficient and environmentally friendly alternative and is already standard in new appliances from renowned brands.
Advantages of R32:
Superior energy efficiency: cools the room faster and consumes less energy;
Lower environmental impact: has a 68% lower GWP than R410A;
Easier to recycle and recharge, as it is composed of a single gas;
Higher thermal efficiency, which improves the split system's performance.
Disadvantages:
It is slightly flammable, requiring additional care during installation and maintenance (although the risk is low);
It may be slightly more expensive, as it is still gaining popularity in Brazil.
Which is best for your air conditioner?
In general, R32 is the most advantageous for those seeking energy efficiency and sustainability.
It represents the future of air conditioning, offering better performance with a lower environmental impact.
However, if your equipment uses R410A, it's not possible to replace it with R32—the systems are designed to work with a specific type of refrigerant.
Therefore, if you're purchasing a new split air conditioner, choose models that use R32. In addition to saving energy, you'll be making a more informed and modern choice.
Conclusion
R32 has arrived to replace R410A with a more efficient, sustainable, and economical solution.
Even with a slight degree of flammability, it is safe when handled correctly and offers better overall performance.
If you're looking for technology, savings, and environmental responsibility, R32 is the best option for your split air conditioner.
