Patent ID: 8100386

Claim:
Enthalpy exchanger, comprising at least one enthalpy-exchanging unit, which enthalpy-exchanging unit: comprises at least one plate, along at least one contact side of which a first liquid medium and a second medium can be displaced while exchanging enthalpy, and comprises at least one hygroscopic material layer which connects to at least one contact side of the plate in contact with the first liquid medium, wherein the mutual orientation of the plate and the material layer is such that a liquid film of the first medium can form between the plate and the material layer, wherein the liquid film is in enthalpy-exchanging contact with both the plate and the material layer, characterized in that the material layer is attached to the plate at a plurality of point locations lying a distance from each other such that the liquid film can extend substantially unobstructed over substantially the whole contact side of the separating wall.
