Auto air -conditioning components are really troublesome，It affects comfort，Second, the compressor consumes the engine power but does not produce it. It is also a great waste。

The refrigeration principle of automobile air -conditioning components is the same as that of home air -conditioning products

For the car，It is different for them to turn on warm wind in winter and air conditioners in summer，Automotive air conditioner is refrigerated by compressor components，And the warm wind is heated inside the temperature of the engine component，and the air attracted from the outside of the car to increase the internal temperature of the car，Air conditioning power seabet myconsumption is mainly due to long working hours，In fact, in my experience, the air conditioner is not cold. Most of the cases are not too serious，Let me talk about some situations encountered in the actual situation，Help everyone understand the reason why the automotive air -conditioning part is not cool before，The cooling principle of automobile air -conditioning components is the same as home air conditioner，But because the air conditioning structure and volume are different，Therefore, the refrigerant product used is different。

Although so, we still have to treat it in a scientific and rigorous attitude，First measure the air conditioner pressure，If the high and low pressure are low, it is basically a lack of cold media products，Add to the pressure to add to the pressure，Can see the results，After changing refrigerant products，The system "refrigeration" is obviously sufficient，The evaporation box will fall to 3.3 degrees，Then the "jump" compressor clutch (in order to prevent the evaporation box from freezing damage，Forced compressor does not work)，The pressure of refrigerant products has dropped by 1Bar，Turned to 14bar。

Adding too much refrigerant products will cause too high system pressure

The air conditioner system is stress，Because the compressor part is suppressed，When the refrigerant product is added too much or the pipeline is blocked, the system pressure will be too high，At this time, the control system will disconnect the compressor electromagnetic clutch seabet loginto stop the compressor，Avoid pressure to continue to increase damage system，At this time, the compressor is not smooth，Of course it won't cool，The solution is very simple，System pressure，After confirming that the pressure exceeds the standard, some refrigerant products can be restored to normal pressure。

Compressor parts are the core of air -conditioning products

Pressure switching parts Damaged evaporator are also called evaporation box，The air duct located under the dashboard，Cold -media products here to vaporize heat and generate low temperature，The airflow is reduced from the small passage on the evaporator component to be reduced when passing through，Because the refrigerant material has been vaporized in the evaporator component，Therefore, its temperature is very low，Easy Frost，Once frost, it will block the evaporator component，So that there is no way to pass the airflow to pass，So there is a temperature sensor component on the evaporator component，When it is close to the frost temperature, it will stop the work of the compressor component，The compressor part is the core component of the air conditioner，Refrigerator material pressure is abnormal、Line failure、Damage to the temperature sensor or belt relaxation，will cause compressor parts to cause failure，Affects refrigeration effect。
