City Multi VRF checks in at top Sheffield hotel

UK: Sheffield’s only 4-star hotel is benefiting from a new air conditioning system based on Mitsubishi Electric’s City Multi R2 VRF units.

Originally a 19th century grammar school, the Leopold Hotel has recently been refurbished to include seven new City Multi R2 VRF outdoor units with heat recovery. 

Consultants Shearstone Mechanical Ltd worked with distributor Kooltech to establish the best solution for the hotel, which could use existing refrigerant pipework. The units were installed by Dronfield-based Greenhill Air Conditioning.

PEFY-P VMS slimline ducted indoor units were installed into each of the 90 bedrooms, with each indoor unit linking back to a branch controller box that sends heating or cooling to each room as required. These boxes were factory-fitted with Kooltech’s K-con port isolation valves, enabling future service and maintenance to individual rooms to be carried out without the need to shut down the complete system.

“Our engineers also installed Mitsubishi Electric’s unique Plasma Quad technology to the indoor fan coils in each bedroom to improve guest comfort and give reassurance on the back of the Covid pandemic,” explained Ian Hunter, director at Greenhill AC.

This award-winning technology improves air quality by neutralising irritants such as pollen, bacteria, dust and viruses, and microscopic particles down to PM2.5, as well as inhibiting SARS-CoV-2.
