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.

Abstract: An air-conditioning control device according to the present disclosure controls air-conditioning units that are an outdoor unit and a plurality of indoor units each having an air outlet. The air-conditioning control device includes: a storage device that stores set input data that includes a space set temperature set for a target space to be air-conditioned and space position information on the target space; and an arithmetic device that performs a control of the indoor units based on the set input data, such that air currents blown from the air outlets of the indoor units are caused to collide with each other in a space located just above the target space and air obtained by collision of the air currents and having the space set temperature is caused to reach the target space.
