1. Introduction
Data center is a facility containing computer equipment and related devices such as storage systems of a telecommunication system. These devices consist of power supply, air conditioner, fire-fighting devices and security systems [1]. Air conditioner of data centers should work full time all over the year to remove the heat added to the system by operation of different devices. Development of telecommunication industry, therefore, made data center a common element for either general or dedicated usage [2]. Heat propagation increases the temperature and causes damage to rack servers; therefore protection of system and prolonging their life by cooling the inherent devices is of crucial importance. In other words, it's very significant to design an appropriate air conditioner to protect data center from destruction caused by heating. For proper operation of devices, they should be held on a certain and proper temperature. Each IT server should receive certain amount of cool air enough for the removal of the produced heating [3]. Appropriate operation of equipment depends on proper distribution of cool air on data center and the response of supply air to the demand of components. Computational fluid dynamics is an assisting tool to configure the hall of devices. Some indexes are used for quantitative assessment of efficient performance of cooling systems. In practice, influence of the design factors is quantified using cooling indexes such as SHI, RHI, RCI and RTI (described in detail later in Section 2) for different models where each index indicates specific aspect of operation in the cooling systems; however in some cases the mismatch among existing approaches might end up with irrelevant results which makes decision making process a challenge. To overcome thedeficiencies of this area, this article proposes a new framework for the quantification and ranking of the performance of cooling systems in data centers by using the results of CFD analysis. In the sequel, first we will review the existing cooling indexes and the theory behind them. Then a new cooling index is proposed for more efficient estimation of the cooling performance of the data center and finally, its application will be elaborated on a real case in Iran considering different configurations for the design of cooling system.
