There is proposed a ventilating device 51 for simultaneous aeration and deaeration of spaces and for recovery of heat from the deaeration media flow, which achieves a high heat recovery capacity. For this purpose, the flow path for the deaeration media flow 67a is dimensioned longer than the flow path for the aeration media flow 67b, the flow path for the deaeration media flow 67a exhibiting, at the outlet side of the heat exchanger 64, a flow deflection 69, 62 which encloses a radian measure - arc alpha - of more than 90@, preferably of 150@. In addition, the flow paths for the deaeration media flow 67b extend in the ascending direction from their inlet openings 61 and 97 respectively, at least as far as the heat exchanger 64. <IMAGE> |
