With changes coming to an air conditioning system near you, Tony Prior looks at a stylish new range of units that come jam packed with added, high-tech features.

I’m always amazed at the variety of innovation that crosses my desk with news and press releases from manufacturers on their latest products and the advanced benefits they claim this brings.

One such story that recently crossed my desk looked at a range of air conditioning units that use the new R32 refrigerant and focused not only on how stylish the manufacturer has made the indoor units, but also just how much advanced technology has been packed in such a small unit.

This includes automatic room sensor technology which scans the body temperatures of people in the room to ensure that the air conditioning runs to match the temperature required. It also helps prevent energy wastage by detecting when a room is empty and turning the system off.

The release covered Coolair Equipment Limited, one of the UK’s leading air conditioning companies, which has just installed the latest wall-mounted system in its Cheshire offices to showcase the future to its customers.

Coolair specifically chose the new M Series MSZ-LN R32 air conditioning from Mitsubishi Electric for its Dunkinfield office to highlight the change in refrigerants now being offered to UK customers and the significant advantages this can bring.

“The existing split heat pump system in our manager’s office had come to the end of its life, so we chose the perfect replacement: with this stylish unit which also shows off the full benefits of the new refrigerant in a fantastic stylish unit”, explained Steve Valentine, Regional Director of Coolair Equipment.

Coolair has more than 30-years’ experience in the industry and has worked closely with Mitsubishi Electric as one of its largest customers.

It's all to do with global warming

The M-Series MSZ-LN wall mounted split system is the first in Mitsubishi Electric’s UK line-up to use R32 refrigerant which has a low global warming potential (GWP) of 675 – less than one third of the most popular refrigerant, R410A.

Following recent changes in legislation, R32 refrigerant is expected to swiftly become the standard for split type air conditioning systems.

In March 2014, European Parliament passed the 2014 EU F-Gas Regulation legislation with the key objective of reducing F-Gas emissions by 79% between 2015 and 2030. The overall aim is to cut availability of hydrofluorocarbons with a high GWP. R32 makes up 50% of the existing R410A refrigerant found in many current systems. In addition, the volumetric capacity of R32 is around 20% higher than R410A, meaning system refrigerant volumes are lower.

Going forward, R32 will play a huge role in helping to reduce the environmental impact from air conditioning systems, heat pumps and refrigeration. What’s more, it’s also easier to reuse and recycle as it’s a single component refrigerant. 

“This new unit gives us a cost-effective method of future proofing our air conditioning systems at Coolair House,” adds Mr Valentine.  “In addition to delivering high performance with a lower GWP, the 3.5kw unit also includes automatic room sensor technology and Wi–Fi control as standard and it was easy to connect to our existing controls which is important to us.”

The new M-Series models have a built-in Wi-Fi interface which enables full control and monitoring via the company’s MELCloud App. The sophisticated 3D i-see sensor within the unit also automatically monitors room occupancy, position and body temperatures to deliver customised comfort.

The MSZ-LN range offers noise levels as low as 19dBA and is available in a choice of four sizes from 2.5kW to 6.1kW, with four distinct indoor wall units which are available in Ruby Red, Onyx Black, Pearl White and Natural White colours. A matching, colour co-ordinated room controller is also available.
