Apollo Building, Ruislip

Apollo Building, Ruislip, the UK's only independent Daikin distributor, recently supplied equipment, specified by Consultants WPPM, to Adcock Refrigeration and Air Conditioning Ltd., for a refurbishment project in Ruislip, Middlesex.

The installation included eight Daikin VRVII, heat recovery, heat pump condensing units and one Mini VRV heat pump condensing unit, serving a total of 110 concealed ceiling ducted fan coil units, complete with Space Air accessories.

Apollo is a two-storey office building of approximately 2,700 sq. metres, originally constructed in the 1980s. The comprehensive refurbishment involved the decommissioning and removal of an existing chilled water fan coil system.

WPPM of Sunbury-on Thames were commissioned to advise on the most suitable air conditioning system that would maximise efficiency in both heating and cooling modes, whilst offering reliability with operation and maintenance cost savings.

Steve Britton of WPPM commented, "We designed the project around Daikin's VRVII heat recovery system due to its application flexibility and energy efficient inverter technology. FXSQ ducted fan coil units were utilised as they represented the ideal solution for both the open plan and smaller office areas. The whole system is controlled and monitored by Daikin's Intelligent Manager; a sophisticated computerised control system, which in conjunction with Watt meters, monitors the day to day operation, running costs for the occupants and can provide remote system observation if required."

Britton added, "The site is situated very close to RAF Northolt so careful consideration was given with regard to the electrical harmonics of the outdoor units to ensure that they would not interfere with the controls of aircraft landing at the airfield."

The overall contract programme was seventeen weeks and the entire VRV installation was completed in just eight-weeks. One important time constraint involved the removal of the old chiller. The proximity of the Building to the airfield necessitated close liaison with the base and a window of just six-hours was allowed to crane-lift the redundant chiller from the roof.

Nigel Claydon of Adcock Refrigeration and Air Conditioning is said to be delighted with the final installation and the fact that the logistics were well executed. The fan coil units were delivered complete with Space Air's accessory ductwork connections, which simplified installation and assisted the project to remain on programme.
