Design method of using external melt ice coil as emergency cold source in data center

The main purpose of the conventional ice storage system is to shift the electrical power use to off peak period and reduce the operation costs. Presents the ice storage device used as the emergency cold source when the normal cooling is interrupted. Provides the special requirements for the ice storage device, and describes the external melt coil how to realize the fast-melting function and expand the ice storage capacity. States the operating modes of this system, discusses some special problems need to be considered in design and gives some solutions. According to a data center project, presents the design process and operating modes in detail.
