Daikin VRV Heat Recovery Air Conditioning Enhances Modern Scottish Commercial Office Development


Wellington House, Aberdeen, is a modern and visually attractive, 2 storey commercial office development by Knight Real Estate in a prime location some 2 miles south of the city centre.

Comprising around 25,000 ft2 of clean and airy grade ‘A’ open plan accommodation complete with high grade finishes, energy efficient glazing and a contemporary styled reception area, the complex also features top of the range Daikin VRV heat recovery air conditioning, installed by Aberdeen based Daikin D1 dealers, Active Air Conditioning Ltd.

The air conditioning comprises 15 REYQ VRV systems with capacities between 33.5 and 44.5kW (cooling) and 37.5 and 50.0kW (heating) supplying a total of 168 Daikin FXSQ concealed ceiling indoor fan coil units. The high quantity of fan coil units provides the developer with very flexible design options for future tenant fit out requirements. Conditioned air, mixed with fresh air within the false ceiling plenum, is supplied to the accommodation areas via low pressure ducting connected to 600mm diameter ceiling mounted swirl diffusers. Internal temperature is maintained at 220C on a year round basis.

Use of VRV heat recovery systems enables heat exhausted from fan coil units operating in cooling mode to be transferred to those areas requiring heating, maximising energy efficiency, reducing electrical consumption and CO2 emissions and resulting in high COPs and EERs at all load conditions. All VRV outdoor condensing units are located in a purpose built compound to the rear of the building.

The air conditioning systems are monitored and controlled on each floor by Daikin Intelligent Touch controllers mounted within lockable cupboards. Future control options are also available to incoming tenants by virtue of wall mounted room temperature controllers located throughout the building to suit design layout requirements.
