If the air conditioning system freezes, it may be that the air conditioning drain hole is blocked, the water content of the air conditioning refrigerant is too high, and the temperature sensor is out of order. Find a professional to check the cause of the fault, and then replace the faulty parts.
Automobile air conditioner is a very important comfort configuration in automobile, which can cool and heat.
The refrigeration principle of automobile air conditioner is actually very simple. When automobile air conditioner is cooling, it is necessary to press the ac button before the compressor clutch is engaged. At this time, the engine will drive the compressor to run.
When the compressor is running, it continuously compresses the refrigerant and delivers it to the evaporation box. The refrigerant expands in the evaporation box and absorbs heat, so that the refrigerant can cool the evaporation box. Cooling the evaporation box can cool the wind from the blower and make the air conditioner outlet blow out cold air.
When the air conditioner is heating, after the warm air function is turned on, the high-temperature coolant in the engine will flow through the warm air groove, and the wind blown by the blower will also pass through the warm air groove, so that the air conditioner outlet will blow warm air.
The refrigerant used in automobile air conditioning is generally r 134a, which needs to be replaced regularly, otherwise it will affect the refrigeration effect and speed of air conditioning.
When replacing the refrigerant, you need to go to a professional store and use professional equipment to replace it. The owner cannot replace it manually.
