Mugen Restaurant, London

Client: Mugen Restaurant, London.
Contractor: Melba Refrigeration
Type of works: supply of high-efficiency air conditioning system.

A high-efficiency air conditioning system from Mitsubishi Heavy Industries Europe (MHIE) is keeping the heat out of a busy kitchen at the Mugen Japanese restaurant in the City of London.

Investing in a new MHIE Inverter Split System was more cost-effective than repairing the kitchen’s five-year-old aircon unit, particularly in the light of the forthcoming ban on R22 refrigerant used in many older systems. Choosing one of the latest MHIE split systems, which utilise eco-friendly R410a, also meant that existing pipework and wiring could be used - minimising cost and disruption for the restaurant.

Mugen combines the best of traditional and contemporary Japanese cuisine and offers diners the choice of relaxing at a table or sitting at the sushi bar for ‘fast food’ with an oriental twist.

When the kitchen’s existing air conditioning system broke down, the restaurant’s owner called in London-based air conditioning specialists, Melba Refrigeration, as the parts required to repair the old R22 unit were no longer available.

Melba’s MD, David Barreto, said: “By installing modern, more reliable and energy efficient equipment, the restaurant can reduce its maintenance liability and operating costs.”

Replacing its old R22 system ahead of the ban on the ozone depleting refrigerant was another benefit for the restaurant. Virgin R22 is now banned for maintenance and servicing refrigeration and air conditioning systems, and all HCFCs, including recycled R22, will be made illegal from January 2015.

Melba Refrigeration has installed an FD Series Split System from MHIE in the restaurant kitchen, sourced through distributor FM Air Conditioning. The compact FDC125VN outdoor unit is located in the loading bay behind the restaurant and has a cooling range of 5.0kW to 12.5kW and heating up to 16.0kW, if required. The unit is connected to a slim profile FDT125V four-way cassette indoor unit, designed by MHIE for all-round air distribution and quieter operation than previous models. The FD is supplied as standard with a wired remote controller (RC-E3) featuring a seven-day/24-hour programmable timer.

An ideal solution for commercial applications such as restaurants, clubs, offices and retail units, MHIE’s FD Split and Multi Split Systems feature a cutting edge inverter controlled compressor that adjusts automatically to meet the precise demands of the indoor unit to save energy and reduce temperature fluctuations. MHIE has also applied its advanced design technology to improve heat exchanger efficiency, enhance heat transfer properties and reduce refrigerant requirements - resulting in an impressive CoP (Coefficient of Performance) rating of 3.71.
