PROBLEM TO BE SOLVED: To provide a heat exchange unit having good load balance with less imbalance of temperature.SOLUTION: There is provided a heat exchange unit having a plurality of heat exchanger systems respectively connected to a plurality of refrigerant circuits. In the heat exchange unit 10, the plurality of heat exchanger systems 50, 60 and 70 include a plurality of tubes 80 arranged in a common ventilation flue 20. The tube arrangement of each heat exchanger system includes a first element in which a tube is arranged in parallel with the tubes of other heat exchanger systems in a width direction of the ventilation flue, and a second element in which a tube is arranged forward or backward with respect to the tubes of other heat exchanger systems in a front-back direction of the ventilation flue. |
