Application analysis of water cold storage technology in a data center

This paper presents the design content of the water cold storage system of a data center project, and analyses and compares the advantages and disadvantages of three kinds of uninterruptible cooling systems using closed cold storage tank， fire reservoir (cooling water make-up pool), independent pool uninterruptible cooling and daytime cooling release system, and the operating expense of the closed cold storage tank and independent pool uninterruptible cooling and daytime cooling release system. After technical and economic comparison, it is not recommended to use a cooling water make-up pool or independent pool for water cold storage in data room projects.
