A heat-exchange unit that is provided with a unit component and with a control unit (70). The unit component has a plurality of heat-exchange devices (20), and each heat-exchange device (20) has a blower (20) and a heat exchanger (40). The control unit (70) is provided with: a re-intake determination unit (72) that determines whether re-intake of low-temperature air is occurring; a wind-direction determination unit (74) that determines wind direction; and a wind-volume control unit (76) that performs one-way control that, when the re-intake determination unit (72) has determined that re-intake is occurring, adjusts the rotational speed of each blower (30) such that a one-way slope that is based on the difference or ratio between the rotational speed of an upwind-device blower (30) and the rotational speed of a downwind-device blower (30) is larger than a steady-state one-way slope and such that the rotational speed of the blowers (30) progressively increases from the downwind device to the upwind device. |
