What refrigerants are used for swimming pool heat pumps?

To fully understand how the pool heat pump works, it is important to look at the very essence of the pump, which are the refrigerants. These can be pure or mixed, liquid or gaseous, and are essential for the proper functioning of the pool heat pump. They allow the transport of calories in the heat pump circuit. Without them, no thermal exchanges, no water at 28°C, no comfortable swimming.

But the impact of air conditioning weighs more and more heavily on the environment. European institutions are stricter and impose regulations aimed at reducing or even eliminating the most polluting refrigerants. Hence the search for new products that reduce the negative impact they can have on the planet. So we went from R22 to R410A, currently replaced by R32.

R410A refrigerant

R410A is a hydrofluorocarbon gas (HFC) composed of half R32 and R125. It was the right solution to take the place of chlorine-rich gases (CFCs), which are particularly harmful to the ozone layer and have been banned for many years. Its energy efficiency is 5 to 6 times greater than the R22 it replaced.

It does not damage the ozone layer but it promotes the greenhouse effect. The major drawback of this gas is its "Global Warming Power" (GWP) which has the high score of 2088 per kilo, which no longer corresponds to current and future standards. It is incombustible but toxic at high temperatures and its decline has been programmed for several years, it is destined to disappear in favor of R32.

R32 fluid has a very low impact on the ozone layer. In addition, since it is pure, it is more easily recyclable.

Compared to R410A, its energy yield is 5 to 10 times more efficient and for the same power output. In addition, 20 to 30% less fluid is required.

Its Global Warming Potential (GWP) is 675 for 1 kilo, it is 3 times lower than R410A.

This fluid has low flammability. The installation must be carried out by a professional authorized to handle this gas.

The R32 offers more performance for the heat pump and less pollution for the planet.

The R32 fluid allows significantly reduce pollution related to the operation of heat pumps. However, there remains a transitional solution since the regulations require air conditioning units to reach a GWP of 400 for the year 2030.

All the ranges of heat pumps distributed by WPool run on ecological gas R32. Also discover the technical elements of a swimming pool heat pump and understand why a defrosting function for the swimming pool heat pump is essential so that you have an overall view of the operation of a swimming pool heat pump.
