R32 refrigerant – what’s it all about?

Mitsubishi Electric R32 refrigerant air conditioning

Depending on how familiar you are with air conditioning systems, you may or may not have heard about one of the new refrigerants on the block, namely R32. It’s being introduced in the UK as an alternative to the widely used R410A, particularly for smaller direct expansion (DX) ‘split’ type systems.

It’s all part of the European phase-down of hydrofluorocarbons (HFCs). F-Gas regulations are in place to reduce HFC refrigerant use by 79% between 2015 and 2030. Over the next 15 years, the HVAC industry will see major changes with new legislation restricting and banning the use of refrigerant gases in certain applications.

So why R32 refrigerant?

Although the commonly used R410A has good energy efficiency, it has a high global warming potential (GWP) of 2088. R32 has just one third of the GWP at 675. It is in fact one of the two components already contained in R410A. Used as a single component, not only does it have a lower GWP, it benefits from being easier to reuse and recycle.

R32 is designated as mildly flammable, however, in the very unlikely event of the entire R32 charge leaking into a room, its concentration would be so low that there would be virtually no possibility of combustion.

That said, R32 does require specialist handling, tools and procedures. Always make sure that any air conditioning contractor installing and repairing equipment containing R32 is fully trained and F-Gas certified in its handling and use.

R32 air conditioning equipment

Leading equipment manufacturer Daikin launched their lower GWP R32 refrigerant across their air conditioning and heat pump product ranges in 2015.

Just this month, rival Mitsubishi Electric has followed suit launching their stylish M-Series. A new line-up of wall-mounted air conditioning units with a sophisticated, streamlined design ideal for the small business market.

As Mitsubishi Electric’s commercial director, Donald Daw explains

“This is a major product evolution which will show the market exactly how air conditioning using R32 can perform. Our engineers have put their heart and soul into developing a superb range of indoor units that offers better efficiencies and more features.”

“We see this model as ideal for high-end, stylish situations and have already had a lot of interest from our customers,” adds Daw.

“R32 is expected to quickly become the standard for split type air conditioning systems and we have more products lined up for the UK market in the coming months.”
