Transitioning to a more sustainable refrigerant

One of our key values at Fujitsu is to minimise impact on the environment wherever we can. One recent step we've taken to uphold this value is switching from using the R410A to the R32 refrigerant in most of our air conditioning models. Let's dive into refrigerants - specifically, the difference between R32 and its predecessor, R410A, and why at Fujitsu we’ve made this all-important switch.

What is a refrigerant?

Refrigerants are a set of chemical compounds used to absorb and convert heat into the cool air you know and love. It’s the key component that allows air conditioners to cool indoor spaces effectively.

Different refrigerants have varying properties and environmental impacts, which is why there's a push towards using more environmentally friendly options.

Why R32?

Lower Global Warming Potential (GWP)

One of the most compelling reasons to choose R32 is its significantly lower GWP compared to the previous refrigerant used, named R410A. In fact, R32 boasts a staggering 67 percent lower GWP[1], meaning it has a much smaller impact on climate change over its lifetime.

Zero Ozone Depletion Potential

Unlike some older refrigerants, R32 is a hydrofluorocarbon (HFC) which has zero ozone depletion potential (ODP)[2], which means it doesn't harm the ozone layer. The use of zero-ODP substances helps to protect the ozone layer and mitigate the harmful effects of ozone depletion, such as increased UV radiation reaching the Earth's surface.

Enhanced Efficiency

R32 offers superior heat exchange properties, which means it provides more efficient cooling and ensures optimal performance across various conditions. This means a R32 unit contains 10-15% less refrigerant compared to a R410A unit with similar heating/cooling capacities.

At Fujitsu, we're committed to sustainability, and we're proud to contribute to this movement. Most of our domestic appliances now use R32 refrigerant.
