The automobile air conditioner has the following working modes when in operation:
1) evaporator self-cleaning mode
The 4 dust thickness sensors are arranged on the surface of the evaporator at equal intervals from bottom to top, and only when the 4 dust thickness sensors 12 sense that the dust thickness on the evaporator reaches a set value, the self-cleaning mode of the evaporator is entered: at the moment, the compressor stops running, the outer fan stops running, the second valve on the condensation recovery water pipe is closed, the first valve on the condensation water drainage pipe is opened, the rotating speed of the inner fan is reduced to 200-plus-one (300 r/s), the condensation water in the condensation water tank above the centrifugal fan impeller hub is thrown to the evaporator through the fan blade from the water outlet hole 13 through centrifugal force, the evaporator is cleaned, the cleaned sewage is discharged outdoors through the condensation water drainage pipe, and when the thickness of dust of the evaporator is sensed by the 4 sensors, the evaporator self-cleaning mode is closed and enters a normal mode. Meanwhile, in the mode, the water in the condensation recovery water tank passes through the fan blade firstly before being thrown to the evaporator, and the fan blade is cleaned. It is to be understood that the number of the dust thickness sensors 13 is not limited to only 4, and may be more than 4 or less than 4. Whether the dust thickness exceeds the standard or not is judged, and self-cleaning is not carried out when the 4 sensors exceed the preset dust thickness value.
Humidification mode
When the humidity sensor in the vehicle detects that the indoor humidity is less than or equal to 50%, the humidifying mode is entered. At the moment, the compressor normally runs, the outer fan normally runs, the valve II on the condensation recovery water pipe is in an open state, the drain valve 7 on the condensation water drain pipe is closed, the rotating speed of the inner fan is increased to be more than 1000r/s, water in the condensation water tank is thrown onto the fan blades at the moment, liquid is beaten into tiny liquid drops, the liquid surface area is greatly increased, after the liquid is contacted with air in the vehicle, the water quickly evaporates and atomizes humidified air, and when the humidity in the vehicle reaches 70%, the humidification mode is closed and enters a normal mode.
Normal operation mode
When the humidity in the vehicle is between 50% and 70% and the dust thickness on the evaporator is within a set value, the air conditioner operates in a normal mode, at the moment, the compressor and the inner and outer fans operate normally, the second valve on the condensation recovery water pipe is in a closed state, the first valve on the condensation water drain pipe is in an open state, and the condensation water is directly drained out of the vehicle.
It should be noted that: the above three modes can be performed during cooling and heating.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
