Chilled Water at Supply Temperature is stored inside a Pressure Vessel capable of being used later to meet air-conditioning load during emergency and power outage when chiller cannot operate During Power Failure in a Data Centre, Server room air starts to heat up; There is Rapid rise in temperature.
Heat will be absorbed by IT equipment and Servers would be prone to damage.
There is Unacceptable temperature rise in 5 mins. Restoring time – Start-up time (Generators + Chiller).
The Solution : Back up Chilled Water for Start-up time of Generators + Chillers
- The Thermal Energy Storage (TES) system starts to supply the stored chilled water to maintain data center temperatures.
- The thermal reserve-maintains cooling of the server rooms during this period, to allow dissipation of residual heat from the servers.
- In the meanwhile, the generator power and chillers are restored.
