A ventilation system including a heat recovery assembly comprising a first heat exchanger (40) for heat recovery having a first flow path (42) and a second flow path (43) to exchange heat energy from air transported in one of paths to the other, wherein a peripheral inlet (46, 60) to the first flow path is arranged to surround a central outlet (51, 63) of the second flow path, and a peripheral inlet (50) to the second flow path is arranged to surround a central outlet (48) of the first flow path, wherein the heat recovery assembly is arranged such that air entering the peripheral inlet (46, 60) of the first flow path exits by a peripheral outlet (61); and air entering a central inlet (62) will exit by the central outlet (51, 63) of the second flow path. |
