Claims (1)
吸気を前面開口部から行なうようにしたドラフト
チヤンバにおいて、 前記前面開口部に取付けられた前面扉と、 前記前面開口部における目標風速を設定するた
めの目標風速設定手段と、 前記目標風速設定手段からの出力信号に基づい
て、前記前面開口部の流入風速が前記目標風速に
一致するように、前記前面扉の開成量を調整する
制御手段とを備えたドラフトチヤンバ。[Scope of claim for utility model registration] Exhaust is carried out by an exhaust fan with a constant exhaust volume,
A draft chamber configured to take in air from a front opening, comprising: a front door attached to the front opening; a target wind speed setting means for setting a target wind speed in the front opening; and the target wind speed setting means. and control means for adjusting an opening amount of the front door so that the inflow wind speed of the front opening matches the target wind speed based on an output signal from the draft chamber.
