Description

本発明のパッケージ型自動消火設備は、消火剤が貯蔵されたタンクユニットと、タンクユニットに接続され、タンクユニット内の消火剤が流れる放出導管と、放出導管を流れる消火剤を放射する消火剤放射部と、放出導管に設けられ、タンクユニットから消火剤放射部への消火剤の供給を制御する電動弁と、消火剤放射部の設置場所の火災を検知する火災感知部と、火災感知部における火災の検知に基づいて電動弁の動作を制御する制御部とを有し、制御部は、火災感知部が火災を検知した際、連続放射期間は消火剤放射部から消火剤が連続的に放射され、連続放射期間経過後は消火剤放射部から消火剤が断続的に放射されるように、電動弁を制御するものである。 The package type automatic fire extinguishing apparatus of the present invention includes a tank unit in which a fire extinguisher is stored, a discharge conduit connected to the tank unit through which the fire extinguisher flows, and a fire extinguisher radiation that emits the fire extinguisher flowing through the discharge conduit. A motor-operated valve for controlling the supply of extinguishing agent from the tank unit to the extinguishing agent radiating unit, a fire sensing unit for detecting a fire at the installation site of the extinguishing agent radiating unit, and a fire sensing unit And a control unit that controls the operation of the motor-operated valve based on the detection of the fire. When the fire detection unit detects a fire , the control unit continuously emits the extinguishing agent from the extinguishing agent radiating unit during the continuous emission period. The motor-operated valve is controlled so that the extinguishing agent is intermittently emitted from the extinguishing agent radiating unit after the continuous emission period.

Claims

A tank unit in which a fire extinguisher is stored;
A discharge conduit connected to the tank unit through which a fire extinguisher in the tank unit flows;
A fire extinguisher radiating section for radiating a fire extinguisher flowing through the discharge conduit;
An electric valve provided in the discharge conduit for controlling the supply of the extinguishing agent from the tank unit to the extinguishing agent radiation unit;
A fire detection unit for detecting a fire at a place where the extinguishing agent radiation unit is installed;
A control unit that controls the operation of the motor-operated valve based on detection of a fire in the fire detection unit,
