In the disclosure, the mobile air conditioner comprises a refrigeration cycle component such as a compressor, an evaporator and a condenser, a chassis, a fan and a water pumping device, wherein the fan is arranged near the condenser and used for leading air passing through the condenser to the outdoor; the condensed water produced on the evaporator is stored in the chassis, the water beating device is fixedly arranged and the part of the water beating wheel is arranged in the chassis, and the water beating wheel is driven by the water beating motor to rotate, so that the condensed water in the chassis is thrown and splashed on the condenser.
Referring to fig. 1, an embodiment of the present disclosure provides a control method for a mobile air conditioner, including:
s110, acquiring a first condensate water level value.
In step S110, the first condensed water level value is a water level value of the condensed water in the chassis, and may be detected by a water level monitoring device, such as a water level sensor.
S120, when the first condensate water level value is equal to or larger than a first preset water level value, controlling to reduce the rotating speed of a fan of the mobile air conditioner; and/or controlling and increasing the rotating speed of a water pumping motor of the mobile air conditioner; so as to adjust the water level value of the first condensed water to be reduced to the preset safe water level value and below.
In this step S120, when the condition that the first condensed water level value is equal to or greater than the first preset level value is satisfied, the following three control processes may be respectively performed: the first control process is used for controlling and reducing the rotating speed of a fan of the mobile air conditioner; the second control process is to control and increase the rotating speed of a water pumping motor of the mobile air conditioner; and in the third control process, the rotating speed of a fan of the mobile air conditioner is reduced and the rotating speed of a water pumping motor of the mobile air conditioner is increased. Any one of these three control processes is optional.
In step S120, the first preset water level value and the preset safe water level value may be determined according to actual conditions, for example, a water level value between one half and two thirds of a highest water level value of the chassis. Namely, the occurrence of water-full shutdown can be avoided in the preset safe water level value. Of course, the preset safe water level value may be the first preset water level value, or may be smaller than the first preset water level value. Optionally, the preset safe water level value is equal to or less than the first preset water level value.
Optionally, the controlling to reduce the rotation speed of the fan of the mobile air conditioner includes: controlling and reducing the rotating speed of a fan of the mobile air conditioner to a first fan rotating speed; alternatively, the control reduces the rotation speed of the fan of the mobile air conditioner at a first reduction rate.

For example, when the water beating motor is a stepless speed change motor, the rotating speed of the water beating motor can be controlled to be increased at a first increasing rate.
According to the control method for the mobile air conditioner, the rotating speed of the fan is reduced, the heat generated by the condenser taken away by the outlet air is reduced, more heat is used for improving the evaporation of condensed water in the chassis, and the consumption of the condensed water is increased; the rotating speed of the water beating motor is increased, so that the amount of water splashed onto the condenser can be increased, and the consumption of condensed water can also be increased; therefore, the water level of the condensed water in the chassis is reduced, and the water level value of the first condensed water is reduced.

And the second preset water level value is greater than the first preset water level value. The consumption rate of the condensed water is improved, the adjustment of the rotating speed of the fan is reduced, and the normal operation of the mobile air conditioner is ensured. In the present embodiment, it is understood that the acquisition of the first condensate water level value is periodically acquired, and in an application scenario (for example, a high-humidity application environment) where a large amount of condensate water is generated, the acquired first condensate water level value is a condition that may directly satisfy a value equal to or greater than a second preset level value, so as to execute the second control process or the third control process.
Of course, in this embodiment, it may also occur that the first condensed water level value first satisfies a condition equal to or greater than the first preset level value to perform the first control process, but when the condensed water level value is acquired again due to a large amount of condensed water generated, it satisfies a condition equal to or greater than the second preset level value to perform the second control process or the third control process.
In some embodiments, obtaining a first condensate water level value comprises: acquiring a plurality of first condensed water level values, and acquiring a current difference value between a current first condensed water level value and a previous first condensed water level value; when the first condensate water level value is equal to or greater than a first preset water level value, controlling to reduce the rotating speed of a fan of the mobile air conditioner; and/or controlling and increasing the rotating speed of a water pumping motor of the mobile air conditioner; the method comprises the following steps: when the current first condensed water level value is equal to or larger than a first preset water level value and the current difference value is larger than zero, controlling to reduce the rotating speed of a fan of the mobile air conditioner; and/or controlling and increasing the rotating speed of a water pumping motor of the mobile air conditioner. When the consumption of the condensed water is less than the generation amount of the condensed water and the water level value of the condensed water reaches the first preset water level value, the control method of the embodiment of the disclosure is executed to increase the consumption of the condensed water.
