Abstract
The invention relates a method for air conditioning of an IT environment which comprises hardware IT devices, computers, memories, telecommunication devices and peripheral devices, wherein a refrigeration supply system of the IT environment has a free cooler, refrigerators and an air circulation system which is operated by means of fans and contains heat exchangers for drawing off the heat generated by the hardware, wherein the method includes the following steps: determining a basic desired value for the feed air temperature of the IT environment on the basis of the existing hardware-configuration, measuring at least one parameter of the hardware which represents a disturbance variable which has a direct or indirect effect on the feed air temperature, and storing the measured value of the parameter, ascertaining a desired value for the feed air temperature from the measured parameter value of the hardware, and raising the target value for the feed air temperature until a critical parameter value is measured, then reducing the desired value for the feed air temperature until the stored value is achieved again, and optionally, if the stored value is not reached within a previously defined time period, resetting the desired value for the feed air temperature to the basic desired value.

11. A method for air conditioning an IT environment which including, as heat generating hardware, IT devices, computers, memories, telecommunication devices and peripheral devices, wherein, in a refrigeration supply system, free coolers, refrigerators and an air circulation system operated with fans and containing heat exchangers for drawing off the heat generated by the hardware are provided;
- comprising;
air conditioning an IT environment with the refrigeration supply system which supplies air with a feed air temperature to the IT environment via the air circulation system; determining a basic desired value for the feed air temperature to the IT environment on the basis of the existing hardware configuration; continuously measuring the electrical power consumption of the hardware and memories and storing a respective value measured in the process; determining a desired value for the feed air temperature from the measured value for the electrical power consumption of the hardware, namely raising the desired value for the feed air temperature as long as no change of the value of the electrical power consumption of the hardware has been detected, then, in the case of detection of an increase of the value for the electrical power consumption of the hardware towards a critical value, lowering of the raised basic desired value for the feed air temperature until the stored value is reached again; optionally, if the stored value of the hardware is not reached within a previously defined time period, resetting of the desired value for the feed air temperature to the basic desired value. - View Dependent Claims (12, 13, 14, 15, 16, 17)
