Type of works: supply of EcoCooling's CREC evaporative coolers for NHS call centre.
In line with the requirement for sustainability, EcoCooling was asked to design a low-energy, low-carbon cooling system for the new NHS call centre at Bow which is to become the HQ for the 2012 Olympics.
Three EcoCooling CRECS (Computer Room Evaporative coolers) have been installed to provide over 80KW of cooling. This includes the required N+1 redundancy to achieve ASHRAE standards. No refrigeration-based equipment will be used.
The EcoCooling CREC is designed to give a saturation efficiency of 90%. This results in a maximum air supply temperature of 23°C. This applies during extreme weather conditions such as those experienced in 2003 when the ambient temperature approached 35°C.
A patented attemperation system maintains a constant temperature supply to the IT equipment. The hot air is mixed with ambient or evaporatively cooled air, using a single damper. When the external temperature rises over a set point the evaporative cooling is enabled to ensure either the typical target air supply temperature of 21°C is achieved or slightly over during the very hottest periods. A standard EcoCooler CREC module will supply ~3 cubic meters per second which can support over 35kW of IT load.
Sustainability was an important element of our bid and underpins our preparations and our vision for the legacy of London 2012 - London 2012 Chairman Seb Coe
