PURPOSE:To effect air-conditioning control efficiently and economically without delaying to the movement of a worker by a method wherein dampers for a present working area and next stage working area are opened by the output signal of a human entering sensor, which detects the movement of the worker, so as to follow the speed of movement of the worker and, thereafter, the damper for the pre-stage working area is closed. CONSTITUTION:The entrances of respective working areas are provided with the human entering sensors S, detecting the entering of the worker M, while respective working area are provided with a plurality of dampers D, which are opened or closed to control conditioning air supplied to respective working area. When the human entering sensor SX detects the worker M, a timer for present working stage and another timer for next working stage are reset by the output signal of the sensor. Accordingly, the output contact SXa is left closed to continue the opened condition of the damper DX while the output contact of the timer for the next stage is closed newly, therefore, the damper DX-1 is opened. On the other hand, the timer for pre-stage is reset by the output signal of the human entering sensor SX and the damper DX-1 for the working area, through which the worker M passed already, is closed. |
