In one embodiment, the determination that the automatic cleaning condition is satisfied is based on the operation state, which may be that the automatic cleaning condition is determined to be satisfied when the time length of the air conditioning unit in the operation mode reaches the first time length, so as to control the air conditioning unit to switch from the operation mode to the cleaning mode.
It will be appreciated that after the unit has been in operation for a period of time, the external surfaces of the surface air coolers tend to accumulate dirt and require cleaning. The first time period is used for indicating that the air conditioner needs to be automatically cleaned after the air conditioning unit continuously operates for the first time period. The value of the first time length may be set in combination with actual requirements, and is not limited herein.
Referring to fig. 1, in the cleaning mode, the shower water valve 135 is controlled to be opened, water for cleaning the surface cooler enters the shower 132 through the shower water valve 135, and the shower 132 sprays the water to the outer surface of the surface cooler 131 to clean the outer surface of the surface cooler 131.

Specifically, the air entering through the air inlet air valve is relatively dry, the air is mixed with the moist environment of the surface cooling section to achieve the effect of reducing humidity, and the air flows, so that the moist air is discharged to the outside through the outdoor air exhaust air valve, and the dehumidification purpose is achieved.
In one embodiment, in the cleaning mode, the method further comprises: the air exhaust valve and the water valve of the surface cooler in the control room are closed.
Referring to fig. 1, in the cleaning mode, the air passing through the surface cooling section is humid air, if the humid air enters the room, the humidity in the room is high, and the indoor exhaust air valve 142 is controlled to be closed, so that the humid air can be prevented from entering the room. The unit stops running in the cleaning mode, and the control intercooler water valve 134 is closed, so that unnecessary energy waste can be avoided.
It can be understood that the surface cooler needs to be cleaned by exhausting air to the outside, and the air direction inside the case is from the air inlet valve to the air outlet valve outside.
In one embodiment, when the time length that the air conditioning unit is in the cleaning mode reaches the second time length, the air conditioning unit is controlled to be switched from the cleaning mode to the running mode.

The value of the second time period may be set in combination with the actual requirement, and is not limited herein.
It should be noted that the values of the first duration and the second duration may be set in combination with an application scenario (e.g., a library, an archive, etc.) of the air conditioning unit, and generally, the first duration is greater than the second duration. For example, the first time period and the second time period are respectively set as three days and one hour, namely, the surface air cooler is cleaned for one hour every three days when the air conditioning unit operates for three days; the first time length and the second time length can also be respectively set as one week and one hour, namely, the surface air cooler is cleaned for one hour every time the air conditioning unit runs for one week.

It should be noted that the water used to achieve the heat exchange has different temperatures in different operating modes. For example, in the heating mode, the water used to achieve heat exchange may be 60 ℃ hot water.
It can be understood that the air needs to be sent to the indoor to adjust the indoor temperature when the unit operates, and the air direction inside the case is from the air inlet valve to the indoor air outlet valve.

In the cleaning mode, the required air volume is larger, and the power requirement on the fan is lower at the moment, so that the fan is controlled to operate at a second lower rotating speed. Accordingly, unnecessary energy waste can be further reduced.
In one embodiment, the fan can adopt an EC fan, and stepless regulation can be realized through the EC fan, for example, stepless speed regulation such as 0.01, 0.02, 0.03 and the like can be taken from the range of 0 to 1, instead of the stepless speed regulation from 0 to 1, so that accurate control of air volume can be realized, and more efficiency and energy conservation can be realized.
