ABSTRACT:
A substance exchange system especially for humidifying gases has at least one bundle of hollow fibers wherein a first flow space surrounds the outside of the hollow fibers and a second flow space is formed by the inner spaces of the hollow fibers with the exchange between the flow spaces being dependent on the exchange characteristic values of the hollow fibers. This substance exchange system is improved with respect to a more flexible determination of exchange quantities which are mutually independent. According to the invention, at least two sub-regions having hollow fibers of different exchange characteristic values are provided.
