With the development of IT industries in recent years, the needs for data centers has been increased together. Data centers in which so many server computers are arranged usually need a large cooling energy, and its energy conservation has been issued. The amount of cooling energy needed is concerned with the distribution of air flow and that of temperature in computer rooms. There are many studies on those conducted by CFD (computational fluid dynamics) simulation, and those have been conducted only in the space for computer rooms but without plenums for the supply and return. In those studies, the boundary conditions of airflow used to be given uniformly throughout the whole region of velocity outlet in the cold aisle. However, there may be a different distribution of air velocity at the velocity outlets constructed with perforated tiles, and the pressure drop through it needs to be applied to the simulation by utilizing porous boundary condition. In this study, the distributions of airflow and temperature formed in the space without plenums were compared with those formed in the space with plenums by CFD simulation. Indices of SHI, RHI, and RTI in each case were investigated. As a results, there were quite large differences between them, and conducting CFD simulations to the space including plenums was recommended as a simulation method.
