Drive out in summer，If there is no air conditioner, it will be torment。What should we deal with the problem of air conditioning in summer? Let's take a look together。

　Auto air conditioner provides energy from the engine

Auto air -conditioning system is to refrigerate the air in the carriage、Heating、Device for ventilation and air purification。It can provide a comfortable ride environment for the car people，Reduce the driver's fatigue strength。At present, the air -conditioning system of most passenger cars is driven by the engine，and all have warmth and warmth function。

Manual air conditioning automatic air -conditioning core components consistent

The control method of vehicle air conditioners is divided into manual and automatic adjustment。Manual air conditioning dial the function keys on the control board for temperature、Wind speed、Control of wind direction。Automatic air conditioning uses vacuum control agencies and electronic execution agencies，For the set air volume、Temperature、Control of wind direction。But the two core refrigeration and heating parts of the air conditioner are basically the same。Air conditioners are generally mainly compressed (compressioner)、Electric Control clutch、condenser (condenser)、Evaporator (Evaporator)、ExpansionValve、ReceiverDrier、Pipe (HOSES)、Concreding Fan、Vacuumsolenoid、Elastor and control system composition。Automotive air conditioners divide high -pressure pipe roads and low -pressure pipe roads。The high -voltage side includes the output side of the compressor、High -pressure pipeline、condenser、Line storage dryer and liquid pipeline; the low -voltage side includes evaporator、Accumulator、Air Pipeline、Compressor input side and compressor oil pool。

Line storage dryer -actually a refrigerant and absorbing refrigerant moisture、Device of impurities。One aspect，It is equivalent to the fuel tank of the car，Refrigerator for leakage of the space that is extra refrigerant。On the other hand，It is like an air filter，Filter the impurities doped in the refrigerant。There is also a certain silicone substance in the storage dryer，It plays the role of absorbing moisture。

condenser and evaporator -although they are called differently，But the structure is similar。seabet loginThey are all honeycomb -shaped aluminum boxes similar to water tanks，This realizes the device for the heat exchange of the material in the external air and the material in the pipeline。The condensation of the condenser refers to the refrigerant in the pipeline from gaseous to liquid。The principle is similar to the heat dissipation water tank of the engine (the difference is that only the water in the water tank has always been liquid)，So it is often installed on the front，Together with the water tank，This design is conducive to using the airflow of the front of the car for cooling。The evaporator is the opposite of the condenser，It is a place where the refrigerant changes from liquid to gaseous (that is, evaporation) to absorb calories。

What should I do if the air conditioner is not cold?

The reasons that can cause the cooling system of the air -conditioning system to cool down and diverse，But many reasons do not need to go to the 4S shop to repair it to exclude，The following，Let's explain several basic air -conditioning failures，If your air conditioner has similar problems，Please check in one by one in our order。

First，Keep the key (AC or ECO) of the compressor opening of the air conditioner。

1. View air conditioning filter element，Excessive air -conditioning filter element will cause small air conditioning air volume and increase air pollution in the car。

2. If your air conditioner is turned on for a period of time, the air volume suddenly becomes smaller，So congratulations，Your air -conditioning refrigeration effect is very good，This is caused by the frozen evaporation box，Just adjust the temperature to。

. If the air conditioner work is normal，But I always feel that it is not as strong as before，So，You need to rinse the condensate board with water，Excessive dust will affect the heat exchange efficiency of the air -conditioning system，to affect the quality effect。

　 4. If the air conditioning refrigeration system is activated，Two cooling electronic fans run at the same time。But the air -conditioning pump does not suck the combination，Of course, the air conditioner does not refrigerate at all，It is likely to be a car computer failure。

5. If the vehicle is too low，It will also cause the air -conditioning pump to repeatedly suck or work，Because the engine computer needs to run the air conditioning pump。seabet appThis fault，You can judge through the working situation of the air -conditioning pump through lightly and observe the work of the air conditioning pump。

. If the above problems are excluded，Then your air conditioner is likely to have no refrigerant (commonly known as fluoride)。Such faulty owners are basically impossible for their own maintenance，You need to go to the 4S shop or repair plant for treatment。

The following operations are not recommended to operate by the owner by themselves:

First is suppression，Inject compressed air into the air conditioner system with air compressor。

Then observe whether the pressure of the system is continuously decreased.

If the system pressure is reduced，You need to use foam water or fluorescent agent to check the leak point，Air conditioning compressor，condenser，Air conditioning pipelines and liquid storage dryers are parts that need to be checked，The leakage point will appear continuous air bubbles after spraying foam。

If there is no leakage point，Then the leakage point is likely to be on the evaporation box inside the center console。

After processing the leakage point，You need to perform the suppression test of the air -conditioning system again，Under the condition of ensuring that the system pressure is unchanged，Implement vacuum of the air -conditioning system。

The air -conditioning system in the vacuum negative pressure state will add an empty inhalation refrigerant to the refrigerant，After adding a certain amount of refrigerant，Mobilize the vehicle and turn on the air conditioner compressor，Continue to add refrigeration，At this time，The air -conditioning system has been fully working and normal。

One of the special explanations is，The more refrigerant is not as good as possible，Vehicle refrigerant must be added in accordance with the model and additional amount of injection，Excessive and less injection or use the wrong model to add a refrigerant will cause abnormal air conditioning work or failure。

Last，If the condition allows，We'd better conduct a simple cleaning and sterilization work on the air conditioning system，The rinse condensing board mentioned earlier，We also have to bring a bottle of air -conditioning cleaning agent。

First，In the case of turning off the air conditioner，Spray the cleaning agent in the air outlet of the car，Then wait for 5 minutes。

seabet appNow，Open the air conditioner，and adjust the wind to the maximum，Spray cleaning agent at the outside of the air conditioner。

Continue to run the air conditioner for about 10 minutes，The cleaning agent carrying pollutants in the air -conditioning drainage holes。

Finally, clean vehicles need to pay attention to opening windows and ventilation.

Please note: You must not sleep in a closed car，Especially when turning on the air conditioner，This will cause hypoxia and cause coma or death。
