Air blower is an important part in automobile air conditioning system, which is also a very easily damaged part in air conditioning system.
Automobile air conditioning, whether refrigeration or heating, is inseparable from the blower.
The principle of automobile air conditioning is actually very simple. When heating, the high temperature coolant in the engine will flow through the warm air tank. In this way, the warm air tank can heat the wind from the blower, so the air outlet of the air conditioning can blow out the warm air.
In refrigeration, you need to press the ac button, so that the compressor clutch will be combined, the engine will drive the compressor to run. The compressor continuously compresses the refrigerant and sends it to the evaporator, where the refrigerant will expand and absorb heat, which can cool the evaporator.
The evaporation box cools the air from the blower, so that the air conditioning outlet can blow out cold air.
Car friends at ordinary times when cleaning the air conditioning system, do not use some inferior foam cleaning agent, this will damage the blower. There is a bearing in the blower. The bearing lacks lubrication and there will be abnormal sound when the blower runs.
