Abstract

A humidification device is provided with at least one stacked unit of water vapor-permeable membranes and of support frames. The support frames are stacked on each other. The membranes each are positioned between two of the support frames, respectively, and have edges clamped between the two support frames. The membranes are arranged parallel and spaced apart relative to each other. Between the two support frames, a supply air flow path extends on a first lateral face of the membrane and, angularly displaced to the supply air flow path, an exhaust air flow path extends on a second lateral face of the membrane facing away from the first lateral face. A flow opening of the supply air flow path and a flow opening of the exhaust air flow path are delimited by the two support frames and extend parallel to a plane of the membrane clamped between them.
