Description
technical field [0001] The invention relates to the technical field of data center cooling and heat dissipation, in particular to a data center diversified comprehensive cooling system and a control method. Background technique [0002] Large and medium-sized data centers usually adopt a water-cooled chilled water system. The chilled water and cooling water pipelines generally adopt the form of double pipelines or ring network systems. There are many valves, and the operation switching mode is complicated. The installation quality of the pipeline system and control system is limited by the construction level and varies. , it is difficult to support and control; the requirements for maintenance personnel are very high, if the operation and maintenance personnel do not have a thorough understanding of the design concept of the system, it is difficult to give full play to the advantages of energy saving of the system; in the early stage when the installed capacity of the data ce...
