Title:
EXHAUST AIR CURRENT QUANTITY ADJUSTMENT METHOD
Document Type and Number:
Japanese Patent JP2020185746
Kind Code:
A
Abstract:
To optimize an exhaust air current quantity in each duct while restricting work load and cost required to install a plurality of ducts.SOLUTION: An exhaust air current quantity adjustment method comprises: a first adjustment step in which an exhaust air current quantity for a first exhaust port is set at a first predetermined value and an exhaust air current quantity for a second exhaust port is set at a second predetermined value by stopping all fans for a first exhaust target and a second exhaust target so that a first damper and a second damper respectively adjust opening/closing degrees; a measurement step in which the exhaust air current quantity of the first exhaust port is measured by operating only the fans for the second exhaust target among the fans for the first exhaust target and the second exhaust target after the first adjustment step; a correction value acquisition step in which, based on a difference between the measured exhaust air current quantity of the first exhaust port and the first predetermined value, a correction value for the first damper and a correction value for the second damper are acquired in order that, while the fans for the second exhaust target are operated, the exhaust air current quantity of the first exhaust port is made equal to the first predetermined value and the exhaust air current quantity of the second exhaust port is made equal to the second predetermined value; and a second adjustment step in which, based on the correction values, the first damper and the second damper adjust the opening/closing degrees.SELECTED DRAWING: Figure 2
