Ventilation box for ventilation installation of livestock building, has heat exchanger positioned in circulation of exhaust air, and fixing unit for fixing box on wall of building between zone to be ventilated and exterior air
The box (1) has an exhaust air circulation unit (31), an exhaust air inlet (32) and an exhaust air outlet (33). A heat exchanger (5) i.e. tube exchanger, is positioned in circulation of exhaust air, where the box has a clean air inlet (41) and a clean air outlet (42). A fixing unit fixes the box on a wall of a building (2) between a zone to be ventilated and exterior air. An orientation unit i.e. trap door, is placed at the clean air outlet for orienting flow of clean air. The exchanger has tubes, and a positioning unit positions the tubes in a parallel with respect to each other. An independent claim is also included for a ventilation installation.L'invention concerne un caisson de ventilation (1), notamment de bâtiment d'élevage, ledit caisson de ventilation (1) comprenant un moyen de circulation d'air vicié (31), une entrée d'air vicié (32) et une sortie d'air vicié (33), et un échangeur de chaleur (5) positionné dans la circulation d'air vicié, et une entrée d'air propre (41) et une sortie d'air propre (42), remarquable en ce que l'échangeur de chaleur (5) est un échangeur à tubes.
