In this blog post we will try to talk about the refrigerant gas in air conditioning. You will be able to clarify the most important characteristics of the new gas, which is being used for the new air conditioning equipment. The new R32 gas provides better characteristics than the previous gases.
In the following points we will try to clarify the reduction of the environmental impact when using this new gas. A fact to take into account is the reduction of up to 30% of the refrigerant charge, so consumption will be drastically reduced. To do this, we will talk about the different types of gas that were previously used.
different types of gas
Although at the moment the new air conditioning models incorporate the new R-32 gas, previously there were other types of gases for this mission. Let’s see what it is.
In the following points we will try to give the basic notions of the old gases so that you can appreciate the importance of the birth of a much more respectful gas with the environment and the ozone layer, such as the new R32 refrigerant gas.
R22 gas
R22 gas was used until 2010, when it was banned, for having a negative impact on the ozone layer. Starting in 2010, alternatives to the gas that existed at that time were sought. Once the new R22 gas was eradicated, another type of gas began to be used, R410A.
R410A gas
This type of gas has been the most widely used in recent years. It has had the defect of increasing global warming, and for this reason, although it has been the gas that has been used the most for air conditioning systems, it has finally been replaced by the new R32 gas.
New refrigerant gas R32
In the next point, we will try to give the most important characteristics that the new R32 gas incorporates , and thus know in more detail the type of refrigerant gas that your air conditioning uses.
- Totally pure gas, giving the possibility of reusing and recycling.
- Drastically reduces environmental impact.
- Low percentage of toxicity and flammable.
- Drastically reduces gas refill costs, even up to 70%.
- It makes it possible to offer air conditioning equipment an energy label of up to A+++.

Everything you need to know about R-32 refrigerant gas
The R32 refrigerant gas is a pure hydrofluorocarbon, that is, it is made up of Hydrogen, Fluorine and Carbon. Like other refrigerant gases, it does not contain chlorine and is therefore not harmful to the ozone layer. However, unlike R410A gas (the most used so far) R32 is more efficient and has a lower global warming potential. These benefits have led many brands, especially Daikin, to bet heavily on this refrigerant gas. Although it also has its cons, since it is more flammable. So, what is true in all this? Is it worth buying an air conditioner that works with R32 refrigerant? In this post we will answer all your questions.
Is R32 refrigerant gas really “new”?
Well, new what is said new is not . The R32 has been known for many years. In fact, R410A gas (the one used up to now) is made up of 50% of this refrigerant. What happens is that it was mixed with R125 to minimize the flammable properties.
So why is pure R32 used now?
After some tests it has been discovered that the refrigerant gas R32 is not as flammable as originally thought. For this reason, the A2L category was created in the security group (according to ISO 817) in which it is classified as “little flammable”.

What safety measures should we take with R32 gas?
To begin with, R32 air conditioners can only be installed by category 2 professionals. The installer must use special tools (manometers with R32 manometric scale and double-acting vacuum pump based on DIN 8975) and with a safety lock. greater responsibility.
In addition, we must carry out an installation project, have ventilation during the placement of the air conditioning and have civil liability insurance. Once installed, pipes cannot be flared inside the home and the owner must hire maintenance and periodic reviews of the facilities.
Is it worth buying an air conditioner with R32?
It depends on the needs of each home or family unit. The larger the installation or the more use we are going to give to the air conditioning, the better we will amortize the initial investment.
In any case, it seems that the R32 will end up replacing the R410A, which is why many people decide to take the leap towards the new technology.
Best R32 air conditioners
More and more manufacturers of air conditioning equipment are betting on the R32. Daikin was the pioneer and behind it have been Panasonic, Mitsubishi Electric, Baxi, Fujitsu, Vaillant… Below we make an assessment of the best air conditioning equipment of similar power and with R32 refrigerant gas.
