Daikin VRV Air Conditioning For “The Best Office Address in Worcester”


The recently completed £8 million Wildwood Triangle office development, Worcester, is thought to be the area’s largest speculative office development to date. Billed by developer, Maximus, as “the best office address in Worcester”, the visually attractive complex comprises 5 self contained, 2 storey blocks offering between 1,800 and 7,800 ft2 per suite of lettable space. Overall, the development provides 40,000 ft2 of much needed high grade office accommodation in this area of the West Midlands.

Each building is supplied with Daikin VRV heat recovery air conditioning, specified by consultants, Hoare Lea, Five ways, Birmingham and designed in association with Direct Cooling Systems Ltd, Notts, who were also the installers.

Five complete VRV systems linked to 99 Daikin FXSQ concealed ceiling ducted indoor fan coil units with capacities between 2.2kW and 7.1kW (cooling) and 2.5kW to 8.0kW (heating), are mounted in false ceilings throughout the open plan and mixed layout offices. Indoor temperatures are maintained at 220 C +/- 2 deg C throughout the year. All VRV outdoor units are mounted in external compounds. Two independent split FTKS/RKS systems supply cooling only to the communications room in building no 5.

Associated heat reclaim ventilation is provided by 17 Daikin VAM units, which deliver between 5.88 and 25.02 m3/min of tempered fresh air and modulate the temperature and humidity of incoming fresh air in order to match indoor conditions, thereby reducing the cooling and heating loads on the air conditioning system. Each VRV system is controlled by a Daikin Intelligent Controller, housed in the maintenance staff areas and linked to remote room temperature controllers within the office areas.

Commenting on the project, a Hoare Lea spokesman stated “Daikin VRV equipment was selected for this high class office development because it offers considerable energy efficiency and ease of installation combined with a huge product range and control options plus cost competitiveness. Daikin were also selected as a result of their class leading reliability, outstanding support and ability to react to queries and design changes quickly and competently.

“REYQ heat recovery systems were chosen to ensure maximum energy efficiency and customer support levels and their high static pressure availability allowed them to be sited in purpose designed compounds to reduce plant visibility. Similarly, FXSQ concealed ceiling indoor units were ideally suited to this type of project because of their compactness, low operating noise and excellent external static pressure characteristics.”
