Abstract
Internet data center are helping to expand the network society throughout the world. These data center require air conditioning to operate, and raising the efficiency of their cooling systems can have significant benefits such as the prevention of equipment failure and the saving of energy as well as improved cost performance. A data center in which much heat-generating equipment has been installed produces a large amount of heat, and achieving a balance between cooling power and fan driving power holds the key to greater efficiency. This paper describes about airflow and thermal environment around server-rack at data center. We evaluated the influence, which indoor temperature and airflow gave to intake temperature of the apparatus.
