The controller is used for receiving the resistance value signal of the resistor body change to regulate and control the fan rotating speed of the air conditioner. The controller can be a fuzzy controller and a PID (proportional-integral-derivative) controller, which is a feedback loop component commonly found in industrial control applications. The controller compares the collected data to a reference value and then uses the difference to calculate a new input value that is intended to allow the data of the system to reach or remain at the reference value. Different from other simple control operations, the PID controller can adjust the input value according to historical data and the occurrence rate of differences, so that the system is more accurate and more stable.
The basic working principle of the fuzzy controller is as follows: the measured state of the controlled object is converted into a fuzzy quantity described by a human natural language through a fuzzification interface, then a fuzzy value of an output control quantity is obtained through fuzzy reasoning according to human language control rules, the fuzzy value of the control quantity is converted into an accurate quantity which can be received by an actuating mechanism through a clarification interface. Therefore, the fuzzy controller receives the signal of the total resistance value change fed back by the knob body, so that the rotating speed of the compressor and the rotating speed of the air conditioner fan are adjusted simultaneously, and the air volume of the air conditioner is changed. And for the principle of variable speed of the compressor: the variable frequency compressor can be divided into two parts, one part is a variable frequency controller, namely a frequency converter; the other part is a compressor. The principle of the variable frequency controller is to convert the alternating current in the power grid into square wave pulse output.

The speed value of the air conditioner fan is output to the speed regulation module 37, the speed regulation module is a speed regulator, and the speed regulation module regulates the speed of the air conditioner fan to the speed regulated and controlled by the controller to ensure that the rotating speed of the air conditioner fan reaches the value required by the controller. And the compressor is cooled by the cooler 361, so that the internal temperature of the air conditioner is not too high, and the practicability of the air conditioner is improved.
Optionally, the temperature values inside and outside the vehicle are obtained through the temperature sensor 31 inside the vehicle and the temperature sensor 32 outside the vehicle, and the temperature inside the vehicle is controlled through the air conditioner controller, so that the temperature difference inside and outside the vehicle is prevented from being too large under the condition that the temperature inside the vehicle is comfortable, and the comfort level of passengers in the vehicle is improved.

And cooling the interior of the air conditioner by a cooler and a cooling fan, wherein the cooling fan is used for cooling the controller. And the cooler is communicated with the evaporator and the compressor through the expansion valve respectively and cools the evaporator and the compressor, so that the internal temperature of the air conditioner is kept not too high, and the service life of the air conditioner is prolonged.
