COOLING DUCT USING DEHUMIDIFYING AND HUMIDIFYING

摘要

The present invention relates to a cooling duct, which is a duct having a flow fan for the flow of a gas and having a hollow fiber membrane so as to remove water from the gas with no or low power and then cool the gas by humidifying the gas using water at low temperatures. A cooling duct according to the present invention comprises: a dehumidifying part removing water from a fed gas; and a humidifying part placed at the rear end of the dehumidifying part and feeding water to the gas from which the water has been removed, wherein the dehumidifying part includes: an inlet part into which the gas is fed; an outlet part from which the gas is discharged; a flow fan placed between the inlet part and the outlet part and allowing the gas to flow; a water remover installed at the rear end of the flow fan and having a hollow fiber membrane capable of selectively absorbing the water from the flowing gas; and a gas-liquid separator connected to the water remover, wherein the gas-liquid separator connected to the inlet part, in which pressure is relatively lower than pressure in the outlet part, so that the hollow fiber membrane is capable of absorbing and separating the water.
