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

摘要

This air conditioning control device (13) is provided with a differential pressure calculation unit (44) which calculates the differential pressure between the suction side and the discharge side of a rack (11) that houses at least one server (18), and a rotation speed control unit (45) which controls the rotation speed of an air conditioning fan (30) on the basis of the differential pressure. The rotation speed control unit (45) increases and decreases the rotation speed of the air conditioning fan (30) on the basis of the amount of change in the differential pressure when the rotation speed of the air conditioning fan (30) has been changed.
