DOUBLE MECHANICAL VENTILATION SYSTEM FOR DYNAMIC POSITION SYSTEM

摘要

A double ventilation system of the present invention increases reliability because the heat emission of self-position control equipment can be stably removed by being formed to discharge to the outside of a room through the free area of an exhaust fan unit after air supplied from a supply fan unit flows in a room by the blasting pressure of the supply fan unit in case of a failure of the exhaust fan unit and being formed to make air flow in the room through the free area of the supply fan unit by the suction force of the exhaust fan in case of the failure of the supply fan unit by including the supply fan unit for supplying air to the inside of the self-position control equipment and the exhaust fan unit which discharges air in the room.
