ABSTRACT:
The invention concerns an independent heat exchange unit designed to be fixed inside a building comprising a box provided with walls defining two fluid passages with an undulating cross-section and means for circulating air capable of causing countercurrent circulation in the two fluid passages of a fresh air stream drawn from outside the building and a stale air stream drawn from inside the building. The walls defining the fluid passages comprise a flexible and thin foil forming undulations capable of being deformed depending on the respective pressure levels of the fresh air stream and the stale air stream. The invention is useful for ventilating and/or air-conditioning the inside of buildings.
