APPARATUS AND METHOD FOR CONTROLLING BLOW

PURPOSE: An apparatus for controlling a blower and a method thereof are provided to decide air volume regarding fluctuation of microorganism count and save conveyance power of a blower or an air control damper depending on saturation of microorganism count. CONSTITUTION: An apparatus for controlling a blower comprises a microorganism counting unit(1), a first smoothing treatment unit(2), a second smoothing treatment unit(3), a memory unit of microorganism reduction capability(4), a first air volume discrimination unit(5), a second air volume discrimination unit(6), and an air volume decision unit(7). The microorganism counting unit measures the number of microorganism in a controlled space. The first smoothing treatment unit treats a first smoothing which is decided by a first smoothing time indicator with respect to the number of microorganism. The memory unit of microorganism reduction capability memorizes capability for removing the microorganism depending on the air volume into the controlled space. The first air volume discrimination unit selects proper air volume for the microorganism reduction capability corresponding to increase of the microorganism which is expected from the result in the first smoothing treatment unit. The air volume decision unit decides the air volume to the controlled space based on the air volumes that the first and second discrimination units are selected.
