Get ready for the new R32 refrigerant gas Mitsubishi Electric (Mr Slim) Air Conditioners

Mitsubishi Electric are preparing to introduce the lower GWP refrigerant R32 across its air conditioning and heat pump product ranges in the UK from 2017.

Mitsubishi Electric, like many of its rivals, have introduced new air conditioning systems using the R32 refrigerant gas, the non-ozone-depleting lower GWP alternative to R410A, in the Far East and Australasia but, until now, the Japanese manufacturer had remained silent on its intentions for Europe.

It has now been revealed that it is to challenge its main rival Daikin, the R32 pioneer, with new products across its main product platforms from 2017. This will include a move to R32 on Mitsubishi Electric’s residential M Series, the commercial P Series air conditioning ranges and Ecodan heat pumps.

Only Mitsubishi Electric’s VRF products will remain on R410A for the time being, although an R32 version of the company’s recently relaunched City Multi HVRF water/refrigerant hybrid will be launched in 2017.

Mitsubishi Electric have said: “R32 will be the predominant refrigerant within their business in the coming years.” They described it as the next generation refrigerant and a good substitute for R410A, despite its slightly higher pressure and mild flammability. There are already millions of R32 units already supplied and installed in Japan and most of Asia, so the UK market is not intended to be guinea pigs.

The R32 benefits from being a single component refrigerant, so making it easier to re-use and recycle, easier to handle, it won’t separate, has no glide and exhibits higher efficiency than R410A. However with limits on charge sizes due to its “mild flammability”, R32 is currently proving a challenge for the VRF range of Mitsubishi Electric products and it appears that is why Mitsubishi has developed its hybrid HVRF solution.

Mitsubishi Electric have said that “The timing for R32 VRF will be advised in due course,” a Mitsubishi Electric UK spokesman stated that, “Our plans are about offering a harmonised solution for customers because we need to avoid the situation where as an industry, we are using different refrigerants on different systems in the same buildings.”

The spokesman also indicated that limited use of CO2 is being considered especially for heat pumps where the predominant load is on hot water.

It seems likely that Mitsubishi Electric will roll out similar R32 introductions across Europe but, so far, there have been no announcements of timings for individual countries.

Chillaire Limited have been involved in some R32 refrigerant gas installations and have been quoting the R32 range for Mitsubishi Electric and other manufacturers such as Daikin for some time now. Our engineers have attended various seminars and have had training to prepare for the new refrigerant.
