Abstract

The present invention relates to a system and method for controlling air conditioning facilities, and a system and method for power management of a computer room. In an air-conditioning facility control system of a computer room (cooling room) equipped with air-conditioning facilities for air-cooling the computer room in which a large number of information processing units are installed, an air-conditioner monitoring and controlling unit calculates a temperature sensitivity coefficient of each information processing unit, and that of each air conditioner, and then determines discharge air temperature of each air conditioner by use of the temperature sensitivity coefficients in such a manner that the sum of squares of a deviation of a change in discharge air temperature of each information processing unit becomes the smallest, and in such a manner that the sum total of the power consumption of the individual air conditioners becomes the smallest.
