The high thermal density of IT servers and the rapid increase in data production are increasing the cooling load of data centers, Energy consumption in data centers are also increasing. In addition, with the advent of the knowledge information · based on smart devices and big data and the activation of cloud servers, the need for data centers are growing, and the demand for data centers are also expected to increase continuously. If we study the energy consumption trends of general data centers, the energy consumption of cooling and air conditioning systems to cool the heat of IT equipment accounts for about 40% of the total energy. In addition to efforts to reduce the power of servers and IT equipment, various methods are being studied to reduce the power consumption of cooling and air conditioning systems. Among them, the data center cooling system through outdoor air cooling achieves a lot of energy savings. Although this method can achieve a lot of energy savings, it causes problems due to environmental restrictions such as an increase in outdoor temperature and it causes problems due to air quality such as inflow of fine dust. Therefore, it is necessary to study a cooling system using a new stable source rather than a method that depends on a cooling system through outdoor air cooling. Among the sources, dam deep water has the advantage of being a stable source because it maintains a temperature suitable for the cooling system of the data center for a long time and the temperature distribution is even. Therefore, we would like to introduce the possibility of utilizing water energy through comparative analysis of power consumption between the IDC pre-cooling HVAC system with Dam deep water-thermal sourse and the air-cooled conditioning system.
