摘要：PURPOSE:To prevent the occurrence of excessive operation due to movementof a man by a method wherein when a man detecting sensor outputs a detecting signal,continuous operation is effected for a given time, and when a new man detecting signal isoutputted during this continuous operation, continuous operation is effected only for agiven time, and thereafter, it is switched to intermittent operation. CONSTITUTION:Whenindoor air is clean and no drive command signal Ss1 is outputted from an air

contamination detecting drive command circuit 20, when a man in a room is moved, a mandetecting signal Sm is inputted from a man detecting sensor 11 to a timer circuit 17. Inwhich case, a motion signal Sm1 is inputted to a drive command signal generating circuit18, a drive command signal Sm2 is continuously inputted to a selection circuit 21 for 30minutes. A selection circuit 21 inputs a drive signal Sd of a LOW operation level to acontrol circuit 22, and a motor 5 is rotationally driven at a low speed through a drivecircuit 23 to starts LOW operation in a low airflow. In which case, when a man in a room ismoved before elapse of 30 minutes, the drive command signal Sm2 is outputted for 10minutes at an interval of a 10-minute rest period. As a result, after LOW operation for 30minutes, 10-minute LOW operation is intermittently effected at an interval of a 10-minutestop period.
