CA 2628727

A device includes a housing having a hollow center and a case having a hollow fiber membrane. The case is at least partially located inside the first hollow center of the housing. A first gas flow flows to the hollow center through an introducing pipe and exits the housing via a discharging pipe. A second gas flow flows through the hollow fiber membrane in the case. The first gas flow enters the case through inflow opening in the case from a gap between a wall of the housing and the case, and exits the case through discharging opening through in the case to the gap between the wall of the housing and the case. The introducing pipe is located adjacent to the dividing wall. The device provides humidifying property by transferring moisture from the first gas flow to the second gas flow or vice versa.

Un dispositif comprend un boîtier comportant un centre creux et une caisse possédant une membrane à fibre creuse. La caisse est disposée au moins partiellement à l'intérieur d'un premier centre creux du boîtier. Un premier flux gazeux s'écoule en direction du centre creux via un tuyau d'introduction et sort du boîtier par un tuyau de décharge. Un deuxième flux gazeux s'écoule via la membrane à fibre creuse dans la caisse. Le premier flux gazeux pénètre dans la caisse via l'ouverture dans la caisse qui s'ouvre dans la caisse depuis un intervalle entre la paroi située entre le boîtier et la caisse et sort du boîtier via l'ouverture de décharge qui passe par l'intervalle entre la paroi du boîtier et la caisse. Le tuyau d'introduction est disposé près de la paroi de séparation. Le dispositif assure une propriété d'humidification grâce au transfert de l'humidité entre un premier flux gazeux et le deuxième flux gazeux, ou dans un sens inverse.
