Air conditioner control device and air conditioner control method

An air control device (3) is provided with: an operation mode acquisition unit (11) that acquires a plurality of operation modes indicating an indoor air conditioner (1-k) to be operated; a temperature data acquisition unit (12) that acquires temperature data indicating the temperatures measured by the temperature sensors (2-1-2-M) when the air conditioner (1-k) is operating; a prediction model generation unit (13) for generating a room temperature prediction model for predicting the temperature measured by the temperature sensors (2-1-2-M) while the air conditioner (1-k) is operating, using the control amount of the air conditioner (1-k) and temperature data acquired while the air conditioner (1-k) is operating as learning data; and an operation mode selection unit (14) that supplies the control amount of the air conditioner (1-k) to the room temperature prediction models, acquires predicted temperatures from each of the room temperature prediction models, and selects one operation mode from among the plural
