Abstract

A heat exchange unit is provided with a unit component and a controller (70). The unit component includes a plurality of heat exchange devices (20). Each of the heat exchange devices (20) includes a blower (30) and a heat exchanger (40). The controller (70) includes a re-sucking determination unit (72) which determines whether re-sucking of low temperature air occurs, a wind direction determination unit (74) which determines a wind direction, and a wind volume controller (76) which executes one direction control when the re-sucking determination unit (72) determines that the re-sucking occurs. The one direction control is configured to adjust a rotation speed of each of the blowers (30) such that a one-direction inclination, which is defined based on a difference or a ratio between a rotation speed of the blower (30) of an upwind device and a rotation speed of the blower (30) of a downwind device, becomes larger than the one-direction inclination in a normal state, and such that the rotation speeds of the blowers (30) gradually become larger from the downwind device toward the upwind device.
