Research on data centers (10) : Uninterrupted cooling and cool storage

Power failure will lead to a data center outage, and the outage of cooling caused by power failure is the main reason. Uninterrupted cooling is an effective solution, with cool storage as the main method. The popular way is water cool storage, and ice cool storage is also a feasible way of energy storage. Cool storage system can operate in off peak power period, which not only improves the economy of data center, but also benefits the balance of power grid. The economic analysis result of an engineering example shows that the economy of a data center can be obviously improved when the design is reasonable, no matter using the water cool storage or ice cool storage.
