But in the last few years, a new problem has surfaced with many computer rooms that is making ductless systems even more of a necessity. The primary reason some computer rooms are in need of special cooling is because of the amount of heat generated from the systems. New servers and communication switches are generating more power, which in turn creates more heat.
According to Liebert Corporation, some of these new computer servers are generating up to 10 times the heat per square foot as they did 10 years ago. In many cases, newer systems installed alongside previous generation systems are creating hot zones. Older data center cooling methods often have difficulty properly managing these new areas of heat.
