DATA CENTER AIR CONDITIONING CONTROL DEVICE, METHOD, NON-TRANSITORY COMPUTER READABLE MEDIUM, AND AIR CONDITIONING SYSTEM

摘要

An air conditioning control device (13) includes a differential pressure calculation unit (44) that calculates differential pressure between the intake side and the exhaust side of a rack (11) containing at least one server (18), and a rotational speed control unit (45) that controls the rotational speed of an air conditioning fan (30) on the basis of the differential pressure. The rotational speed control unit (45) increases or decreases the rotational speed of the air conditioning fan (30) depending on the variation of the differential pressure in the event of a change in the rotational speed of the air conditioning fan (30).
