Preferably, the step of "transporting the collected condensate to the cooling tube group 2" includes: obtaining the water level in the water collecting member 1; if the water level in the water collecting member 1 reaches a preset water level, the collected condensate water Transported to cooling pipe group 2. That is to say, when the water in the water collecting member 1 reaches the preset water level, the collected condensate is sent to the cooling tube group 2. Among them, the specific steps of "sending the collected condensate to the cooling tube group 2" include: starting the water pump 5 so that the collected condensate is sent to the cooling tube group 2. In addition, those skilled in the art can flexibly set the specific preset water level value of the preset water level in practical applications, as long as the water level boundary point determined by the preset water level can determine when to send the collected condensate to the cooling pipe Group 2 is fine.

The following describes the technical solution of the control method of the present invention with a specific embodiment. As shown in FIG. 1, the air conditioner further includes a low-water inlet pipe 6. One end of the low-water inlet pipe 6 is connected with the water collecting member 1, and the other end is connected with The tap water 200 is connected, and the low-water inlet pipe 6 is also provided with a low-water inlet valve 7. The low water inlet valve 7 is connected to the controller of the air conditioner, and the controller can control the start and stop of the low water inlet valve 7.

First, make the air conditioner execute the cooling mode. In this mode, the indoor heat exchanger works as an evaporator, and the outdoor heat exchanger works as a condenser. The indoor heat exchanger continuously produces condensed water, and the condensed water in the water collection member 1 continuously Accumulate, the controller continuously obtains the water level data from the water level sensor to obtain the water level in the water collecting member 1. If the water level in the water-collecting component 1 reaches the preset water level, it means that the water in the water-collecting component 1 can be directly transferred to the cooling tube group 2 to perform auxiliary cooling on the outdoor heat exchanger, but if the water level in the water-collecting component 1 is not When the preset water level is reached, the amount of condensed water in the water collection member 1 does not meet the conditions for auxiliary cooling of the outdoor heat exchanger. The low water inlet valve 7 should be controlled to open in time to allow the tap water 200 to enter from the low water inlet pipe 6 The water collection member 1 is supplemented with water. During the water supplement process, the water in the water collection member 1 reaches the preset water level before the water in the water collection member 1 is delivered to the cooling tube group 2, and the outdoor heat exchanger is further cooled . Preferably, the preset water level is set to enable the water in the water collecting member 1 to be delivered to the cooling tube group 2 to fill the cooling tube group 2 so as to ensure the cooling effect of the outdoor heat exchanger. Wherein, if the water level in the water collecting member 1 does not reach the preset water level, the low-level water inlet valve 7 is controlled to open to supplement water to the water collecting member 1 through the tap water 200. Through this arrangement, the water in the water collecting member 1 When the water level is low, water can be added to it in time to ensure the cooling effect of the outdoor heat exchanger.

In addition, in the process of cooling the outdoor heat exchanger by the cooling tube group 2, the controller obtains temperature data from the temperature sensor to obtain the water temperature in the water collector 31. By judging the water temperature, it can be determined whether the water in the water collector 31 can still be used for auxiliary cooling of the outdoor heat exchanger. Because the auxiliary cooling of the outdoor heat exchanger needs to ensure that the water temperature in the water collector 31 is not too high , Otherwise the auxiliary cooling effect cannot be achieved. When the water temperature in the water collector 31 is lower than the preset temperature, it means that the water in the water collector 31 can continue to be used for auxiliary cooling of the outdoor heat exchanger. At this time, close the drain valve 36 and open the circulating water valve 35 (the order of closing the drain valve 36 and opening the circulating water valve 35 is not limited) to circulate the water in the water collector 31 back to the water collecting member 1. When the water temperature in the water collector 31 When the temperature is not less than the preset temperature, it means that the water in the water collector 31 cannot continue to be used for auxiliary cooling of the outdoor heat exchanger. At this time, the circulating water valve 35 is closed and the drain valve 36 is opened (wherein, the circulating water valve 35 and the open The execution sequence of the drain valve 36 is not limited), the water in the water collector 31 is drained to the drain area 100. The preset temperature may be the heat dissipation temperature of the outdoor heat exchanger. Of course, as mentioned above, the preset temperature is not limited to the heat dissipation temperature of the outdoor heat exchanger.
