Abstract

An air conditioning control device includes an operating-unit specifying unit, an adjacent-unit specifying unit and an adjacent-unit control unit, and collectively controls the operation of an indoor unit group. The operating-unit specifying unit specifies an operating unit to perform an air conditioning operation from the indoor units included in the indoor unit group. The adjacent-unit specifying unit specifies an adjacent unit adjacent to the operating unit from the indoor units included in the indoor unit group. The adjacent-unit control unit causes the adjacent unit to perform an air flow generating operation. This air flow inhibits air conditioned by the air conditioning operation of the operating unit from diffusing from an air conditioning target space.
