Title: Ventilator controller
Inventor: FUJIMOTO HIDEAKI
IPC: G05D7/06
Filed: 1988-12-19
Abstract: PURPOSE:To prevent an overload state of a drive motor when a ventilator is started by setting a start ready state of the ventilator when the velocity of an air current is reduced down a prescribed level of or less. CONSTITUTION:When a damper B-b is opened, the air current produced by a ventilator B-A flows into a ventilator B-B via a damper B-B and the velocity of the air current is measured by an airflow meter 2. In case this measured value is larger than a prescribed level, the start of the ventilator B-B is locked. In other words, the trip of a power circuit due to the overload is prevented in case an adverse air current flows into the ventilator B-B at a velocity higher than a prescribed level. Then the start lock of the ventilator B-B is released when the velocity of the air current is reduced less than a prescribed level. Thus the overload state of the ventilator B-B can be avoided at its start up. Then the power circuit never trips.
