Abstract

An air conditioning control device includes a storage device that stores a plurality of analysis conditions to which respective priorities are assigned, and a result of an airflow analysis for each of the analysis conditions, and an arithmetic device that controls an air-conditioning apparatus. The arithmetic device includes an airflow analysis unit that performs the airflow analysis for the plurality of analysis conditions in order of priority from highest to lowest, an airflow control feasibility determination unit that determines, in accordance with a generation state of an analysis result provided by the airflow analysis unit, whether or not airflow control can be started for the air-conditioning apparatus, and an operating state decision unit that, when the airflow control feasibility determination unit determines that the airflow control can be started, decides on an operating state of the air-conditioning apparatus in accordance with an analysis result provided by the airflow analysis unit.
