PURPOSE:To reduce the thickness of a ventilator having a heat exchanger for exchanging heat between exhaust gas and suction gas by providing a special separator inside the heat exchanger provided to integrally rotate with a centrifugal fan. CONSTITUTION:An indoor side exhaust port 6 and an indoor air supply port 9 are provided at the frame 1, and a specific fan casing 10 is disposed, thereby laterally arranging an outer air exhaust port 7 and an outer air supply port 8 at the other side. A centrifugal fan 3 is provided to intake air from both sides into the casing 10, and a heat exchanger 5 made of porous fiber is integrally held as an annular unit inside the blade. The separator 11 is displaced at an angle theta at the side of expanding the start 10-1 of the casing 10 in the fan 3. A shutter 8-1 is openably provided at the port 8, thereby constructing the ventilator. |
