AIR CONDITIONING CONTROL DEVICE AND AIR CONDITIONING CONTROL METHOD

An air control device (3) includes: an operation pattern acquiring unit (11) to acquire operation patterns indicating an operation target air conditioner (1-k) in a room; a temperature data acquiring unit (12) to acquire temperature data indicating a temperature measured by a temperature sensor (2-1 to 2-M) when the air conditioner (1-k) is in operation; a prediction model generating unit (13) to generate, using a control amount of the air conditioner (1-k) and temperature data acquired when the air conditioner (1-k) is in operation as training data, a room-temperature prediction model for predicting the temperature measured by the temperature sensor (2-1 to 2-M) when the air conditioner (1-k) are in operation; and an operation pattern selecting unit (14) to provide the control amount of the air conditioner (1-k) to the room-temperature prediction model to acquire a prediction temperature from each of the room-temperature prediction models, and selects one operation pattern from the operation patterns on the basis of the prediction temperature.
