Document Type and Number:
Japanese Patent JP3449321
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an air volume control device, capable of setting the air volume of a tap-switching type fan delicately employing the switching of taps.
SOLUTION: A medium tap MT is switched to a low tap LT during a predetermined reference time (one hour for example) while the allotment of the time is regulated. The middle air volume between an intermediate air volume corresponding to the medium tap MT and a low air volume corresponding to the low tap LT can be achieved as the average air volume in the reference time. The total amount of ventilating air in the reference time is regulated in such a manner.
