Evaporative Cooling in the water Industry

Yorkshire Water required a flexible data centre facility with initial technical load of 150kW expandable to 350kW.  A key element of the design was efficiency to meet both environmental and financial objectives.  

The first phase consists of 6 EcoCooling CRECs each providing air up to 30kW of cooling. During cool conditions incoming air is warmed by mixing the hot exhaust air with the cold air from outside. In warm conditions full fresh air is used and in very hot conditions evaporative cooling is enabled.

The maximum relative humidity is controlled using the unique EcoCooling dynamic RH control. The input air will not exceed 80% giving full compliance against ASHRAE allowable standards.

Electrically Commutated (EC) fans are used for the supply and extract. These provide the best efficiency with full speed control. The control system minimises the fan speed according to the room ΔT. This ensures the absolute minimum energy is used by the system.

Remote control and monitoring is provided through a local network and is fully integrated with all other functions. Operating mode and set points can all be managed remotely. Operating parameters and faults are also reported.
