Research of Data Center Fresh Air Ventilation Cooling System

A variety of data centers have come into being as required by the continuous development of social network and information technology; meanwhile, wide concern has been aroused about the issue on data center’s high energy consumption in which the air conditioning energy consumption accounts for more than 40 %. Thus, it is of great importance to achieve the energy conservation of air conditioning system in data center. According to the new requirement for IT equipment performance and new design range of temperature in data center, this paper presents a full fresh air ventilation and cooling scheme for ambient temperature control of data center, which, without mechanical refrigeration equipment and under the premise of meeting the design requirements for ambient temperature, has greatly reduced the energy consumption and provided a new idea for the design of next-generation data center.
