PURPOSE:To reduce noise from a heat exchanger unit. CONSTITUTION:A heat exchanger unit includes a centrifugal fan 5 disposed in a ventilation passage 7 of a unit body 1 and a substantially square-shaped heat exchanger 9 disposed so as to surround the centrifugal fan 5, and is adapted such that air discharged from the centrifugal fan 5 by the rotation of the centrifugal fan 5 is fed to the heat exchanger 9. A control plate 21 extending toward the centrifugal fan 5 is mounted on the side of the suction of a straight line shape part 9a of the heat exchanger 9. |
