Parallel operation strategy analysis of multiple open cooling systems in data centers

Presents the common problems during the parallel operation of multiple (three or more) open cooling towers in the water cooling system of the data center, such as the cooling tower overflow or suction, the short-term temperature rise of chilled water caused by mode switching, and it is not easy to carry out chemical cleaning and coating of cooling water system. In order to solve these problems, proposes that the maximum loop of the open cooling system is no more than 2 sets, and the loop system can be divided into a single system.
