Have you ever thought about how your AC generates cooling? You must also have heard the AC technician talk about filling gas in the AC to maintain its cooling? Ever thought what gas it is?

It is none other than the AC Refrigerant which is filled in the condenser coils of the AC for its effective cooling. It is simple – if there is no refrigerant in your AC, its cooling or freezing system won’t work as needed and thus there will be no cooling.

Yes, the refrigerant is so much important for the efficient working of the AC and so is its selection. You can find a good number of refrigerant options available in the market but the call is to pick the right one. A carefully chosen refrigerant will not only be effective in cooling but will also help save electricity.

Here, we are highlighting the detailed comparison of the two most amazing and popular refrigerants of AC – R32, and R410A.


R32 vs R410A AC Refrigerant Gas:

What is an AC refrigerant?

In simple words, a refrigerant is a compound in the liquid or gaseous state that powers AC, fridge, etc. with their freezing technology.

Working of the refrigerant:

The refrigerant absorbs the environment’s heat and combines it with compressors and evaporators to produce cool air. Generally, in the AC, the refrigerant is present in the inner copper coils. As the refrigerant absorbs the outside heat, it changes its state from gas to liquid.

This generated liquid then comes outside and a fan blows some hot air on the coils and exhausts to the outside. At this very point, the refrigerant cools back and changes its state from liquid to gas. The fan again blows air on the coils which result in distributing cool air throughout the place.

This whole cycle is repeated again and again and this is how the refrigerant manages to offer cool air to the place without any hassles.

Now when you have a good understanding of refrigerant and its working, let us get into the details of a quick comparison between R32 and R410A.

A summary of R410A:

R410A is made with the combination of R32 and R125; both of which are chlorine-free. One of the best benefits of this refrigerant is its no damage efficiency on the ozone layer but its capacity to cause global warming is 2088 times than that of carbon dioxide; which is a concerning factor.

R410A is one of the popular choices in terms of refrigerant as it has high-efficiency energy ratings and is also eco-friendly. Many popular AC brands are using this refrigerant like Voltas, LG, Samsung, Hitachi, Godrej, Whirlpool, etc.

A summary of R32:

Without any doubt, R32 is the rising and trending names in the refrigerant industry. Many big AC manufacturing companies are now switching to use this refrigerant and are extremely happy with the final results.

One of the biggest benefits of this refrigerant is that it is quite easy and convenient to recycle. Also, it is very much eco-friendly and causes no harmful impact on the ozone layer depletion. It is also one of the trusted names in terms of better and dedicated performance for effective cooling and energy efficiency.

Moreover, it has GWP value as 675, which is one concern, but the value is certainly lesser than the available R410A. With all its reliability, R32 is one of the best choices when it comes to eco-friendly and affordable refrigerants.

After the summary of both the refrigerants, now let us have a quick look at the comparison of both the options to know which one is better than the other.


R32 vs R410A – which is better?

Both R32 and R410A belong to the Hydro-fluorocarbons refrigerant class. These refrigerants are not harmful to the ozone layer and don’t cause its depletion. But, these refrigerants are somewhere responsible for global warming for sure.

Though both the refrigerants cause global warming, it is important to know which out of the two is better. Here are some important factors which can help understand the difference between the 2 popular refrigerants.

Composition Between R32 & R410A AC Refrigerant Gas:

R32 is pure di-fluoro methane whereas R410A is a mixture of Penta-fluoro ethane and di-fluoro methane. Because R32 is the pure version of di-fluoro methane, it is quite easy to handle.

Both the refrigerant are almost the same and work similarly, they only differ in terms of their density. R32 is lower in density than R410A and as a result, it is used in a lesser amount.

Clearly, in terms of the composition, R32 stands above R410A and is the upgraded and better version of R410A.

Global Warming Effect:

Well, as we all are aware that refrigerants are one of the major causes of global warming, therefore, it is essential to understand their impact on the same.

Since R32 is required in a lesser amount as a refrigerant, it causes lesser or minimal impact on global as compared to R410A.

Other than this, the Global Warming Potential (GWP) score is the measure to analyze the impact on the global warming scenario. The higher the GWP score, the higher are the chances to cause global warming. R410A has a GWP of 2088 whereas R32 has GWP as 675; this means that there are 2088 times more chances that R410A can cause global warming as compared to R32.

Here, again R32 stands as a clear winner above R410A.

Ozone layer depletion:

The ozone layer is one of the essential factors that prevent the harmful rays of the sun to damage the earth’s environment and climate. It acts like a blanket over the earth’s atmosphere.

Generally, most of the refrigerant has a negative impact on ozone depletion but both R32 and R410A cause 0 capacity damage to the ozone layer. In short, there is no harm or danger to the ozone layer from either R32 or R410A.

As a result, both R32 and R410A stand strong with their 0 negative impacts on ozone depletion and thus can be used without any second thoughts.


Final Verdict:

Based on the analysis of these essential parameters, it can be said that R32 is the clear winner over R410A. It is stable with its composition and causes a lesser impact on global warming with no damage to the ozone layer.

R32is a clear choice when choosing between R32 vs R410A.

  1. ” As the refrigerant absorbs the outside heat, it changes its state from gas to liquid.”
    “the refrigerant cools back and changes its state from liquid to gas”

    Are you sure of this? I think you have erred here.
