The aerator comprises a general support (22) for an outer air (28) and an advanced air channel (24), a heat exchanger (48) with a small spacing (c) folded or rounded off heat conducting surface elements (42) with alternating outer air-/supply air channels (44) in the longitudinal direction (L) separated, air tight, with discharge air-/advanced air channels (46) in the opposite direction. There is also a non-heat exchanging supply air-bypass channel (40), in the region of the heat exchanger, with a locking mechanism (88,94) for the exchanger and the bypass channel. There is at least one supply air-outlet opening (56) in the chamber (10), and at least one intake opening (62) for discharge air of the chamber with a discharge filter (66). There is at least one supply air- and discharge air ventilator (60) for the counter running separated air streams (30,64). |
