PROBLEM TO BE SOLVED: To give a chaos fluctuation to an air flow to generate a variation in air flow which is similar to a natural air flow change so as to enhance the comfortableness, by performing a position control of a louver in response to a chaos fluctuation data on the position of the louver which manipulates the direction of blow-off air flow from an indoor apparatus and a command time for the operation of the louver based on frequency characteristics given to the air flow. SOLUTION: In a louver control device which manipulates the direction of blow-off air flow from an indoor apparatus by controlling a plurality of louvers, a chaos fluctuation data on the position of louvers is obtained based on a chaos formula by chaos fluctuation computing means 1 and this data is outputted to louver position control means 3. Command time setting means 2 outputs a signal which indicates a command time to the louver position control means 3. This louver position control means 3 outputs the louver position which is determined based on the reference louver position while considering a fluctuation component which is an output from the chaos fluctuation computing means 1 to a louver motor 4. Due to such a construction, the direction of blow-off air from the indoor apparatus can be fluctuated in a chaotic manner, thus obtaining a variation in air flow which is similar to the natural air flow change. |
