METHOD AND DEVICE FOR REDUCING THE HUMIDITY OF A GAS IN A HOUSING INTERIOR

摘要

The invention relates to a method and a device (20) for reducing the humidity of a gas in a housing interior (11), in particular in a battery housing interior, wherein a gas is led through a first selectively permeable membrane (24) into an intermediate space (21) having the first selectively permeable membrane (24) as an inlet (23) and a second selectively permeable membrane (26) as an outlet, and the gas is then cooled in the intermediate space (21) by a cooling unit (27) such that a water vapor portion of the gas is condensed into water and the gas having a reduced water vapor content is directed through the second selectively permeable membrane (26) into the housing interior (11).
