Energy Consumption Analysis of Data Center Cooling System Based on TRNSYS
Frequency conversion technology and natural cooling technology can effectively reduce the energy waste of refrigeration system of data center.A data center in Shanghai is taken as the research object and this paper uses TRNSYS simulation platform to establish the energy consumption model of its refrigeration system to analyze the energy consumption of the original fixed-frequency pump system,variable frequency pump system and variable frequency+natural cooling system of the data center.The results show that the frequency conversion system and frequency conversion+natural cooling system can effectively reduce the power usage effectiveness(PUE)of the data center.When the load rate is 100%,the PUE of the frequency conversion system is 1.34.When the load rate is 100%,PUE of frequency conversion+natural cooling system is 1.27.
