Data processing room, or sometimes called computer/server room, needs a special room condition in order to maintain the performance of such equipment. High temperature and humidity could cause the decrease of performance, and even equipment failure. Data processing equipment, especially server, dissipates high sensible heat that needs to be handled.

A proper cooling system is very important especially for thermal management of IT equipment with high heat loads such as 1U or 2U multi-core, high-end servers and blade servers which provide more computing per watt. Many problems like high inlet temperature due to the mixing of hot air with cold air, local hot spots, lower system reliability, increased failure, and downtime may occur.

Data centers [...] IT equipment consumes considerable amounts of energy, which is released in the form of heat. In order to dissipate the generated heat, it is necessary to use air-conditioning systems whose task is to maintain appropriate air conditions inside the server room.
