In order to keep the data center server room temperature condition, cooling energy consumption has been rapidly increased as the increasing internal heat gain from the server devices. And the cooling units for server systems are fully operated to satisfy the indoor temperature condition, it results in the excessive energy consumption. There are many wastes of cooling energy which is caused by the structural problems in data center server room. For example, a leakage by the electric cable hole, mixing or recirculation of hot air from the hot aisle to the cold aisle, short circulation of the CRAC(Computer Room Air Conditioning), and others. So there are many strategies to reduce the waste of cooling energy in data center.
In this study, cold aisle containment system and variable air volume system were proposed among the various strategies to reduce the energy cosumption. To verify the effectiveness of the energy saving system, test bed which is same with exist server room was set up in IDC(Internet Data Center) building and comparative experiments were carried out in actual conditions. As the result, in case of setting server room temperature 30℃, the server device inlet temperature exceeded 27℃ class 1 condition of the ASHRAE standard. But in case of setting server room temperature below 26℃, the range of inlet temperature of server system was 18～26℃ by cold aisle containment system. In case of variable air volume system and setting server room temperature 26℃, total energy saving was 19.8% to conventional cooling system. After all, variable air volume system and cold aisle containment system were proved to be the effective solution for energy saving cooling system.
