PROBLEM TO BE SOLVED: To provide a marine biofouling prevention device and a marine biofouling prevention method for boats and ships, capable of preventing adhesion and growing of marine organisms in a sea-water intake box, which takes in cooling water for an air conditioner.SOLUTION: A marine biofouling prevention device 30 has: a chemical-solution pipe 43 having a chemical-solution tank 45 and a chemical-solution pump 41 distribution pipes 59 branched from the chemical-solution pipe 43 and respectively connected to a plurality of sea-water intake boxes electromagnetic valves 51, 52, 53 and 54 respectively provided at distribution pipes 59 and a control unit 32 which controls driving of the chemical-solution pump 41 and opening/closing driving of the electromagnetic valves at respectively set time points. The control unit 32 is connected to an air-conditioner control board 110 through a control signal line. When the control unit 32 drives the chemical-solution pump 41 and opens the electromagnetic valves, a stop control signal is output to the air-conditioner control board 110 to temporarily stop the air conditioner of an air-conditioning device 100, in the marine biofouling prevention device 30.COPYRIGHT: (C)2014,JPO&INPIT【課題】空調機用冷却水を取り入れる海水吸入箱の海洋生物の付着育成を防止できる船舶用の海洋生物付着防止装置及び付着防止方法を提供する。【解決手段】薬液タンク45及び薬液ポンプ41を備えた薬液配管43と、前記薬液配管43から分岐されて複数の海水吸入箱に各々接続される分配配管59と、前記分配配管59に各々設けられる電磁弁51,52,53,54と、前記薬液ポンプ41の駆動及び前記電磁弁の開閉駆動を、各々設定された時刻に制御する制御部32を有する海洋生物付着防止装置30であって、前記制御部32が空調機制御盤110と制御信号線により接続され、前記制御部32は、前記薬液ポンプ41を駆動して前記電磁弁を開くとき、前記空調機制御盤110に停止制御信号を出力して空調装置100の空調機を一時停止させる海洋生物付着防止装置30とする。【選択図】図3
