Abstract:
1. A method for controlling an air conditioner which conditions air sucked from closed space through an air inlet, and then discharges the conditioned air to the closed space through an air outlet, thereby controlling a state in the closed space to a predetermined target state, the method comprising: setting a target value for controlling a physical quantity representing the state of the closed space; during a moving predetermined time period in which the air conditioner is operating, first measuring the physical quantity of the air discharged through the air outlet, or sucked through the air inlet over time; during the time period second measuring the physical quantity over time at least one position in the closed space which is not near the air outlet and the air inlet; during the time period first calculating a moving average of measurements of the physical quantity obtained at one of the air outlet and the air inlet, in the first measuring; during the time period second calculating a moving average of measurements of the physical quantity in the closed space obtained in the second measuring; calculating a correction amount by subtracting the moving average of the measurements of the physical quantity obtained at the one of the air outlet and the air inlet during the time period from the moving average of the measurements of the physical quantity obtained in the closed space; adding the calculated correction amount to the physical quantity measured in the first measuring to calculate a physical quantity for control, and controlling operation of the air conditioner during the time period in such a manner that the physical quantity for control is the target value.
