If you are thinking of buying an air conditioner, you should know what type of gas it uses so that you do not get caught up in it.

Although these days time seems to have given us pause, summer is the time to refrigerate our house. Maybe making use of some of the classic tips or by making use of fans. Two valid alternatives but far from the comfort it provides an air conditioner.

Some devices that require minimal maintenance and that dominate balconies and facades in a country that, like Spain, is characterized by having a good number of sunny days a year. This is not a good time to buy and install an air conditioner for reasons such as price increases, less stock and, above all, fewer installers (as many are saturated).

However, if you decide to put one of these teams at home, You can find out first about which refrigerant gas it uses, since not all are equal in this aspect.

And it is that, to date the gas that has generally been used to run air conditioning systems has been R410A gas. It is a type of gas that came with the Kyoto Protocol (successor to the Montreal Protocol) in a way that sought to minimize the use of refrigerant gases that damaged the ozone layer.

It thus came to replace R22 gas, the most used to date and that caused the most damage to our atmosphere. This materialized in a change, in the adoption of R410 gas, a gas that is not toxic, kinder than R22 but which was not perfect either.

And it is that despite being less harmful, R410A is a gas that has a high index of “Global Warming Potential” (GWP or Global Warming Potential, which is the measure used to determine how a gas affects the increase in the greenhouse effect). It is a better gas than the previous one but it can be improved.

Community legislation

In the European Union they then chose to legislate on the subject As a result of this work, they approved a new Community Regulation (517/2014) that sought to regulate the use of the different gases that could influence the greenhouse effect.

Then R32 gas arrived, a more environmentally friendly refrigerant gas as it requires less refrigerant charge than equipment with R410A and is also more efficient. Improvements that resulted in a decrease in the impact on global warming, reducing the incidence by up to 75% when compared to R410A.

Some manufacturers committed themselves to the use of R32 gas and in fact we found some equipment that already makes use of this type of refrigerant gas. In this way, they seek to comply with the regulations and, on the other hand, contribute to reducing the greenhouse effect.

Differences between R32 and R410A gas

We have already seen that a gas, R32, is less polluting than R410A in case of accidental leaks, the latter being more harmful to the environment. But What are the other fundamental differences?

  • R32 is pure so it is easier to recycle. R410A is composed of two gases, R32 and R125, so it is more difficult to recycle.
  • R-32 refrigerant gas is much more ecological and respectful with the environment.
  • R32 gas has an A2L rating which means it has a low level of flammability and toxicity.
  • R32 has a 75% lower impact on global warming when compared to R410A.
  • The R-32 refrigerant gas is better in thermal transmission and energy efficiency (it uses 30% less refrigerant than R410A) reaching the A +++ classification while the R410A remains in A ++.
  • R32 gas consumes less energy at low outside temperatures.

And it is that how it usually happens, the problem with these gases is given above all by the specific leaks due to equipment malfunction or lack of maintenance, as well as when reusing and recycling them. This is when that gas can be released into the atmosphere and pose a threat to the environment.

How to identify the gas used

This is all very good you may think, but How can I know what type of gas is in my air conditioner? A question that has a very easy answer.

We can know the type of gas that each air uses from the manufacturer’s website, so that we can be informed before buying it. And the Mitsubishi Electric website serves as an example.

If we already have it at home, the gas used is generally specified in the instructions for use, on the energy efficiency label or if we no longer have those papers, in the stickers that are usually located both on the split as in the outer machine.

It should be remembered that for now the R32 gas is not too widespread, so the most common is to find teams that make use of the R410A. The key is that this gas can be replaced if at a certain moment we want to use R32. For this we must first contact an authorized installer and second that our equipment has both the pressure gauge and the vacuum pump compatible with the new gas that we are going to use.
