1. A thermal load estimation device comprising:
state estimating circuitry to estimate a state amount of a target area at an estimation target time by using measurement data obtained, by measuring a state amount of the target area, air conditioner operation data indicating an operation state of an air conditioner disposed in the target area, and an estimation value of a thermal load of the target area; and
thermal load estimating circuitry to estimate the thermal load of the target area at the estimation target time, by using the measurement data, the air conditioner operation data, and an estimation value of the state amount of the target area,
wherein the thermal load estimating circuitry estimates a plurality of thermal load candidates corresponding to values of thermal loads as the thermal load of the target area, calculates a likelihood of each of the thermal load candidates by using the measurement data, the air conditioner operation data, and the estimation value of the state amount of the target area, and estimates the thermal load of the target area from the plurality of thermal load candidates on a basis of the calculated likelihood, and
wherein a process in which the state estimating circuitry estimates the state amount of the target area by using the estimation value of the thermal load of the target area estimated by the thermal load estimating circuitry, and a process in which the thermal load estimating circuitry estimates the thermal load of the target area by using the estimation value of the state amount of the target area estimated by the state estimating circuitry are alternately performed, so that a thermal load likely to be the thermal load of the target area at the estimation target time is estimated.
