PURPOSE:To keep substantially constant the volume of discharged air and its temperature and facilitate energy saving by providing a damper control device which opens and closes a damper by an access sensor and controlling variably the capacities of a compressor and fan of an air conditioner according to the number of times of opening said damper. CONSTITUTION:When one of man detecting sensors S1-S7 detects a worker F, the damper of dampers P1-P7 which corresponds to the one of work areas E1-E7 which corresponds to said access sensor opens and the one of air discharge ports M1-M7 which corresponds to said damper opens to discharge cold air. On the other hand if the worker F leaves said work area of the work areas E1-E7, said access sensor of the sensors S1-S7 does not detect man, and the damper of the dampers P1-P7 that corresponds to said work area opens and said air discharge ports is closed to stop discharging cold air. Further, a CPU outputs control signals which variably controls stepwise the capacity of an indoor fan 5 and of compressor 4 from output ports C1-CK and D1-DL to an inverter drive circuits 13 and 14 according to the number of openings of the air discharge ports M1-M7, that is the number of openings of the dampers P1-P7.
