Air temperature and humidity in the data center are controlled permanently
and reported to a superordinate monitoring system. A high-precision air
conditioning system by Liebert HIROSS keeps the temperature constant
electronically at a value that is optimal for the servers. Continuous control
and, if necessary, adaptation of air temperature grant protection against
excessive thermal strain on the hardware in the racks.
