BRIDGE DEHUMIDIFYING DEVICE USING ELECTRIC HEAT EXCHANGER

摘要

PURPOSE: A bridge dehumidifying device using electric heat exchanger is provided to extend the life of a bridge by preventing the internal corrosion of a box girder. CONSTITUTION: The bridge dehumidifying device using electric heat exchanger comprises: a connection pipe(100) connecting both ends of two box girders(11) arranged in a row on a pier; an indoor heat exchanger(120) installed in one of the box girder to cool down the air flew in through a guide duct(110), to condense the moisture caused by cooling down the air, then to discharge the condensate to the outside of the box girder; an outdoor heat exchanger(170) attached to one side of the box girder to condense the inner refrigerant by the circulation of the outside air; an outdoor ventilator(180) installed to one side of the outdoor heat exchanger(170) to circulate the outside air compulsively to the outdoor heat exchanger(170); and an exhaust unit installed under the indoor heat exchanger(120) to discharge the condensate from the indoor heat exchanger(120) to the outside of the box girder.
