Anonymous users2024-02-10Abnormal, under normal circumstances, the temperature will be above 0 degrees, and when using the air conditioner to cool down normally, most of them will be set at about 3 5 degrees! If it is minus 40 degrees, it is definitely a problem with the sensor or controller! It is normal to operate under extreme conditions (in areas with minus 40 degrees Celsius in winter, turn on the refrigeration mode and turn on the external circulation)!
But, no one will use it like this, freeze to death!

Anonymous users2024-02-03Frosting in the evaporator of an automotive air conditioner is largely caused by refrigerant leakage.
Refrigerant leakage in the air conditioning system will cause the evaporation pressure of the air conditioner to be too low when it is working, and the evaporation temperature is proportional to the pressure.
If the low-pressure end is below kPa, there is a high chance of frost formation on the evaporator surface.

Anonymous users2024-02-02Generally, the evaporator of the automobile air conditioner will have an evaporator temperature sensor, and the whole system is in good condition through the monitoring of the air conditioning amplifier (air conditioning controller).
The general is to stop the compressor, or reduce the compressor speed.

Anonymous users2024-02-01The evaporator temperature sensor is broken, or the air conditioner amplifier is broken.
After using for a period of time or driving a certain mileage, the automobile air conditioning system is in the state of internal circulation or external circulation, and a large number of dust and impurities are adsorbed on the surface of the automobile evaporation box, among which the position of the evaporation box is dark and damp, and it is most likely to accumulate dust and scale.
Air conditioning deterioration is a layer of frozen moisture condensed in the air conditioning system's low-pressure pipes and on the surface of the condenser.
The distribution steps for cleaning the car air conditioner by yourself are as follows: >>>More
The cleaning frequency of the vehicle air conditioning system mainly depends on the use environment, if it is humid and dusty, it should be cleaned once a year, and the air conditioning filter is best replaced, which can increase the air volume and reduce the odor. It is advisable to go to a professional repair station for cleaning.
Car air conditioners do not need to be refilled with water. A modern air conditioning system consists of a refrigeration system, a heating system, a ventilation and air purification device, and a control system >>>More
