Abstract:
An air conditioning control device includes a differential pressure calculation unit that calculates differential pressure between the intake side and the exhaust side of a rack containing at least one server, and a rotational speed control unit that controls the rotational speed of an air conditioning fan on the basis of the differential pressure. The rotational speed control unit increases or decreases the rotational speed of the air conditioning fan depending on the variation of the differential pressure in the event of a change in the rotational speed of the air conditioning fan.
