London Ambulance Olympic Call Centre

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.
