Abstract

PURPOSE: To properly control the ventilating amount of air to each room, by a method wherein a motor to drive ventilating fans is controlled in such a manner as to rotate at a low speed when valves opened are small in number, and to rotate at a high speed when valves opened are large in number.
CONSTITUTION: The valves 6, 7 and 8 which can freely open and close air paths are provided to suction air ducts 3, 4 and 5, respectively. The rotation of a motor 12 to drive ventilating fans is controlled to a low speed, when valves 6, 7 and 8 are not all opened, and it is controlled to a high speed, when two or all the valves 6, 7 and 8 are opened. With a motor 12 being controlled in such a manner, it can be rotated at a high speed to increase the discharging amount of air from ventilating fans, when rooms which need to be ventilated are large in number, on the other hand, it is rotated at a low speed to decrease the exhaust amount of air from fans, when the number of rooms which need to be ventilated is small. Therefore, proper amount of ventilating air can be ensured to each room, though the number of rooms which need to be ventilated is changed.
