The arrangement of the water inlet pipe 14 realizes that the delivery pump 4 pumps the condensed water in the water collecting structure 2. The presence of the drainage opening at the bottom of the water collecting structure 2 facilitates the pumping of water from the water collecting structure 2 by the delivery pump 4. Meanwhile, the conveying pump 4 is also provided with a first water outlet, the heat exchanger 5 is provided with a second water inlet, one end of the water outlet pipe 15 is communicated with the first water outlet of the conveying pump 4, the other end of the water outlet pipe 15 is communicated with the second water inlet of the heat exchanger 5, and the arrangement of the water outlet pipe 15 realizes that the condensed water pumped by the conveying pump 4 is drained into the heat exchanger 5.

The heat exchanger 5 is in a water-free state, which means that no condensed water is stored in the heat exchanger 5 or that the condensed water stored in the heat exchanger 5 has been discharged. When the water level H1 in the water collecting structure 2 is greater than or equal to the preset water level value Ha, it indicates that a sufficient amount of condensed water has been collected in the water collecting structure 2, and the transfer pump 4 needs to be controlled to start, and the water valve 9 needs to be controlled to close, so that the transfer pump 4 pumps the condensed water in the water collecting structure 2 into the heat exchanger 5 and stores the condensed water.

The heat exchanger 5 is in a water state, that is, condensed water collected in the water collecting structure 2 is injected into the heat exchanger 5, and the heat exchanger 5 and the second inner fan 6 are performing auxiliary cooling of the condensed water. When the water level H1 in the water collecting structure 2 is again equal to or higher than the preset water level value Ha, it indicates that a sufficient amount of condensed water is again collected in the water collecting structure 2. And the condensate water collected again is usually lower than the temperature of the condensate water stored in the heat exchanger 5 at the moment, and in order to improve the cooling efficiency, the water valve 9 is necessary to be controlled to be opened, the second inner fan 6 is controlled to stop running, so that the warm water in the heat exchanger 5 is drained, and after the drainage is finished, the condensate water in the water collecting structure 2 is continuously pumped into the heat exchanger 5 again by starting the delivery pump 4. For judging whether the heat exchanger 5 is in a water-containing state or a water-free state, the current state of the heat exchanger 5 can be judged by setting a pressure sensor in a position close to the upstream of the water flow of the water valve 9 in a drainage port of the heat exchanger 5 and acquiring the water pressure.
