Specifically, the operation of the compressor, the upper fan 300, and the lower fan 500 is controlled by the controller. Wherein the upper fan 300 is operated at a low speed, and can supply air to the evaporator 100, and the evaporator 100 absorbs heat of the supplied air, so that condensed water is generated at the evaporator 100. At this time, the exhaust temperature is not high, the temperature of the condenser 200 is not high, the condenser 200 does not need excessive heat dissipation, and the lower fan 500 operates at a low rotating speed, so that the power of the lower fan 500 can be reduced, and the power consumption is reduced. The operation of the lower fan 500 can dissipate heat of the condenser 200, and prevent heat generated by the condenser 200 from flowing to the evaporator 100, which affects the evaporator 100 to generate condensed water.
And S63, judging whether the exhaust temperature is lower than a second preset temperature, if so, performing a step S64, and if not, performing a step S65, wherein the first preset temperature is lower than the second preset temperature.

And S64, the compressor keeps running at the current frequency, the lower fan 500 runs at the second preset rotating speed, the upper fan 300 runs at a rotating speed not lower than the fourth preset rotating speed, and then the step S4 is carried out. The upper fan 300 specifically operates at a fourth preset rotating speed, the second preset rotating speed is greater than the first preset rotating speed, and the second preset rotating speed is a centered rotating speed. Wherein the upper fan 300 is operated at a low speed, and can supply air to the evaporator 100, and the evaporator 100 absorbs heat of the supplied air, so that condensed water is generated at the evaporator 100. Exhaust temperature is not high or low this moment, and condenser 200 temperature is also not high or low, and condenser 200 needs the heat dissipation of certain degree, and fan 500 is in order the rotational speed operation between two parties down at this moment, can guarantee the heat dissipation to condenser 200, also can guarantee that fan 500's power can not be too high down, reduces power consumption. The operation of the lower fan 500 can dissipate heat of the condenser 200, and prevent heat generated by the condenser 200 from flowing to the evaporator 100, which affects the evaporator 100 to generate condensed water.
And S65, the compressor operates in a frequency reduction mode, the lower fan 500 operates at a third preset rotating speed, the upper fan 300 operates at a rotating speed not lower than a fourth preset rotating speed, and then the step S4 is performed.

Wherein the upper fan 300 is operated at a low speed, and can supply air to the evaporator 100, and the evaporator 100 absorbs heat of the supplied air, so that condensed water is generated at the evaporator 100. At this time, the discharge temperature is too high, and the compressor is subjected to frequency reduction in order to protect the compressor and prevent the compressor from tripping. The exhaust temperature is too high, which may cause the temperature of the condenser 200 to be too high, and the condenser 200 needs to be rapidly cooled, at this time, the lower fan 500 operates at a high speed, which may rapidly cool the condenser 200, and may prevent the heat generated by the condenser 200 from flowing to the evaporator 100, which may affect the evaporator 100 to generate condensed water.
And S7, judging whether the water pumping motor reaches idle rotation noise, if so, performing a step S8, and if not, performing a step S9. After the water level in the water receiving tank 400 is reduced, the noise of the water fetching motor can be reduced, and when the noise of the water fetching motor is reduced to idle noise, the water level of the water receiving tank 400 reaches a low water level warning line, and a water pump needs to be closed.
And S8, starting timing by using a timer, and closing the water pump and the water pumping motor after timing.
