在数据中心，主要挑战是处理IT设备和空调(AC)设备的功耗。为了降低数据中心的总能量，已经提出了许多技术和方法。这些策略侧重于服务器的空闲功率或控制交流机组，同时独立考虑服务器机架的温度。本文提出了一种主动控制快门，能够在独立考虑服务器温度的情况下控制冷却气流。通过该方法，可以消除冷却能量的浪费。在对该方法的仿真中，采用了一种传统的任务分配方法，并考虑了启动延迟。此外，还对主动控制快门的效果进行了评估。百叶窗通过观察服务器的温度来阻挡来自冷通道的冷空气。因此，可以通过防止空闲或关闭的服务器的过度冷却来降低AC的冷却功率。实验结果表明，该方法降低了22.8%的制冷能耗。
In a data center, the main challenge is dealing with the power consumption of IT equipment and air conditioning (AC) units. To reduce the total energy in a data center, many techniques and approaches have been proposed. These strategies focused on the idle power of servers or controlling AC units while considering the temperature of server racks independently. In this paper, an active controlled shutter that enables the control of cooling airflow was proposed while considering the temperature of servers independently. By using the proposed method, wasted cooling energy could be eliminated. In a simulation of the proposed method, a conventional task assignment method was used, and start-up delays were considered. Additionally, the effect of the active controlled shutter was evaluated. The shutter blocks off cool air from cold aisles by observing the temperature of a server. As a result, the cooling power of the AC can be reduced by preventing the excessive cooling of idle or shut-down servers. An experimental result shows that the proposed method reduced the cooling energy by 22.8 %.
