PRODUCTS & SERVICES AET supplies comfort cooling to Blackheath High School AET Flexible Space has supplied an underfloor air conditioning system to Blackheath High School, London, to provide comfort cooling for students in the new learning zone. The school has recently invested 18m in developing its facilities, including a new library and resource centre. These are located on the lower ground floor, sunk beneath the existing site and the new courtyard area. Because of the underground location of the resource centre, air conditioning was required. An underfloor system was specified by consultant Hilson Moran so the ceiling space, featuring unique pyramidal skylights, could be left exposed. Underfloor air conditioning makes use of the plenum beneath a raised access floor to distribute conditioned air. A single CAM-V33 direct expansion downflow unit serves the air conditioned zone, and the conditioned air is supplied by 14 TU4 fantiles. The CAM-V receives spent air back for reconditioning via high-level transfer grilles. A major challenge was the 900mm-high underfloor void within the main resource area, requiring special modification to the CAM baseframe and raised floor substructure.

The s-MEXT connects directly to Mitsubishis direct expansion MrSlim Power Inverter outdoor units, to createa full inverter split system. It is also the firms first packaged computer room air conditioning (CRAC) unit. In addition, the s-MEXT is the first Mitsubishi Electric hydronics and IT cooling systems product to carry the three diamonds, taking advantage of more than 50 years experience within the IT cooling market oftheRC brand, plus Mitsubishi Electrics quality standards. The units are available in capacities from 6kW to 42kW and are ideal for applications where high sensible cooling and close control of temperature and humidity are required, such as small and medium sized businesses (enterprise data centres) with on-premise IT cooling requirements. They are also available in both upflow and downflow variants.

Edpacs indirect air-to-air evaporative cooling system will maintain the temperature across CIXs data halls without using chillers and using 75% less energy than a traditionally cooled data centre. The installation of the low-energy cooling system was part of a 6m (5.29m) extension at the 2,800m2 data centre.
