A ventilating device 51 for the simultaneous aeration and deaeration of spaces and for the recovery of heat from the stream of deaeration medium is proposed, which achieves a high heat recovery capacity. …<??>To this end, the flowpath for the stream of deaeration medium 67a is dimensioned to be longer than the flowpath for the stream of aeration medium 67b, the flowpath for the stream of deaeration medium 67a possessing a flow deflector 69, 62 on the outlet side of the heat exchanger 64, which deflector encloses an arc alpha of more than 90 DEG , preferably of 150 DEG . Moreover, the flowpaths for the stream of deaeration medium 67b extend from their inlet apertures 61 and 97 respectively at least as far as the heat exchanger 64, in a rising direction. …<IMAGE>… |
