HULL DUCT FOR NOISE REDUCTION IN ENGINE CONTROL ROOM IN SHIPS AND AIR FLOW IMPROVEMENT

摘要

PURPOSE: A hull duct for reducing noise of an engine control room in a ship and improving air flow is provided to satisfy noise control standard of an engine control room and to apply to a drying technology for all the ships in which a main air inlet hull duct and the engine control room are closely arranged. CONSTITUTION: A hull duct(200') for reducing noise of an engine control room(100') in a ship and improving air flow comprises an inlet part(220) and an outlet part(210). An engine control room and the hull duct maintain a certain gap. Air flows into the inlet part from a blower(500). The inlet part is widely formed. The outlet part is flown out toward an engine room and is narrowly formed.
