Analysis on series and parallel systems of cold storage tanks in data centers

This paper presents the classification and application scenarios of cold storage tanks in data centers, and discusses the concept and significance of the thermocline. The design points of series and parallel systems, valve switching logic and their respective characteristics of cold storage tanks are compared and analysed particularly. In general, the parallel system is superior to the series system, and has the advantages of the simple pipeline system, control logic, and lower cost. At the same time, the parallel system could avoid the problem of a brief heating up at the end of the air conditioning when the power supply is restored in the form of a series system.
