Method and apparatus for controlling and monitoring of an air conditioning system for data processing systems.

摘要

Method for controlling and monitoring of an air conditioning system for a data processing system (1), the at least one server-cabinet (40) for receiving electrical assemblies, of at least one air conditioning apparatus (10) of hot air via a warm air suction (11), cooled and sucked in via a result of the blowing-in (14) indirectly or directly into the at least one server-cabinet (40) or in a cold aisle (50) is blown by at least one server-cabinet (40) is limited, with of at least one server-cabinet (40), cold air from the cold aisle (50) is filtered off with suction and into a separate hot aisle cold aisle (50) or in the surrounding space is conveyed, with a respective temperature of a respective supply air and exhaust air of the at least one air conditioning apparatus (10) by means of respective temperature sensors (20, 21) and the inlet and outlet side, a temperature of a cooling medium which one or more heat exchanger (12) in the at least one air conditioning apparatus (10) for deriving a heat loss flows through, by means of a further temperature sensors (30, 31) is determined on the input side and output side, is evaluated and the power of at least one fan (13) in the air conditioning apparatus (10) is controlled, characterized in that the regulation of a cooling capacity of the at least one air conditioning unit (10) in at least two different, predetermined modes is carried out, whereby in a first mode a conveyed air volume of the at least one fan (13) at a maximum predeterminable temperature difference between the sucked-in hot air and cold air is delivered to a minimum value is regulated, and in a second mode the cooling power is regulated in such a way that a maximum predeterminable temperature for the purposes of the one or more heat exchanger / n (12) is not exceeded cooling medium flowing.
