Mechanical ventilation assembly for e.g. residential building, has vertical rod moveable between closed position and elongated position of seal joint which is compressed against corners of heat exchanger in its closed position

摘要

The assembly has corner units (16) including two spaced frames (25, 26) that are connected to each other through by an intermediate vertical rod. The rod extends along the length of the frames and includes a flexible seal joint (17). The rod is moveable between a closed position and an elongated position of the joint, where the joint is compressed against corners of a heat exchanger (15) in the closed position.
