For another example, when the main control board 15 is disposed between the fan module 12 and the first side wall 113, the pipeline module 16 may be disposed between the fan module 12 and the bottom wall 116, and the pipeline module 16 may also be disposed between the fan module 12 and the first side wall 113 or the second side wall 114, and when the main control board 15 and the pipeline module 16 are disposed between the fan module 12 and the same side wall, for example, the main control board 15 and the pipeline module 16 are disposed between the fan module 12 and the first side wall 113, the main control board 15 is disposed near the top wall 115 relative to the pipeline module 16, and the pipeline module 16 is disposed near the bottom wall 116 relative to the main control board 15, so as to facilitate water-electricity separation of the air conditioning unit 10, and facilitate efficient operation of the air conditioning unit 10.

The pipeline module 16 includes a water inlet module 161 and a water outlet module 162, wherein the water inlet module 161 and the water outlet module 162 are both connected to the heat exchanger 13, for example, the water inlet module 161 may be connected to an inlet end of the heat exchanger 13, and the water outlet module 162 may be connected to an outlet end of the heat exchanger 13. The water inlet module 161 may include a water inlet tube 1611, the water inlet tube 1611 being configured to provide a circulating medium for the heat exchanger 13. The water outlet module 162 may include a controller 1623, a water outlet pipe 1621, and a switch valve 1622, where the switch valve 1622 is disposed on the water outlet pipe 1621, so that chilled water, glycol, etc. may enter the heat exchanger 13 through the water inlet pipe 1611, and be discharged through the water outlet pipe 1621 after heat exchange by the heat exchanger 13.

When the temperatures detected by the first temperature sensor 122 and the second temperature sensor 123 are higher, the heat exchange efficiency of the heat exchanger 13 is insufficient, at this time, the main control board 15 can control the controller 1623 to adjust the opening of the switch valve 1622, so that the opening of the switch valve 1622 is increased, the circulating medium can be accelerated to be discharged out of the water outlet pipe 1621, and a new circulating medium flows into the heat exchanger 13 from the water inlet pipe 1611, thereby improving the heat exchange efficiency of the heat exchanger 13, and the rotation speed of the fan 121 is reduced compared with the rotation speed when the temperatures detected by the first temperature sensor 122 and the second temperature sensor 123 are higher, thereby being beneficial to reducing the energy consumption of the fan 121.

When the temperatures detected by the first temperature sensor 122 and the second temperature sensor 123 are lower, the heat exchange efficiency of the heat exchanger 13 is sufficient, and at this time, the main control board 15 can control the controller 1623 to adjust the opening of the switch valve 1622, so that the opening of the switch valve 1622 is reduced, and the circulating medium can be discharged out of the water outlet pipe 1621 in a decelerating manner, thereby being beneficial to saving the use of the circulating medium and improving the energy efficiency of the air conditioning unit.
