Abstract:

Provided is a heat-exchanging ventilation fan comprising a housing (41) having formed therein an outside air inlet (8), an outside air outlet (1b), a discharge air inlet (1a), a discharge air outlet (7), a supply air passage (33), and a discharge air passage (32). The heat-exchanging ventilation fan also comprises: an air supply fan (3) for generating a supply air current in the supply air passage (33); an air discharge fan (2) for generating a discharge air current in the discharge air passage (32); and a heat exchanger (5) for exchanging heat between the supply air current and the discharge air current. The outside air inlet (8) and the discharge air outlet (7) are formed in the rear surface (6) of the housing (41). The heat-exchanging ventilation fan further comprises: a surrounding wall (34) raised from the rear surface (6) and collectively surrounding the outside air inlet (8) and the discharge air outlet (7); a housing-side partition section (10) for dividing the region surrounded by the surrounding wall (34) into a region having the outside air inlet (8) formed therein, and into a region having the discharge air outlet (7) formed therein; and a facing plate for covering the inside of the surrounding wall (34).
