Description
Summary:Nowadays, the total power consumed by data centers is increasing more and more. In particular, the power consumed by data center facilities accounts for about half of total input power. In this paper, a hierarchical control structure is proposed for efficient management of an indirect adiabatic cooling system, which utilizes fresh air. Data center cooling needs can be met with various combinations of modes of operation that can be set by a supervisor to maximize the overall operating efficiency. Here, the best combination is determined by solving an energy based optimization problem, which is faced by means of a nature-inspired optimization algorithm. The effectiveness of the proposed control system is evaluated by resorting to a simulation environment, that is developed in Matlab/Simulink and where the performance of the computers room air conditioning unit is described.
