This condition may be caused by a coolant leak. When this happens, check the car's cooling system. Car heating uses engine heat. When the car air conditioner heats up the heat, the high-temperature coolant in the engine will flow through the hot water tank, and the air blown by the blower will also pass through the hot water tank, causing the car's empty air outlet to blow out warm air.
The car air switch is an important comfort configuration in the car. The air conditioner switch can be used for cooling or heating.
During the cooling process, the compressor clutch will engage and the engine will drive the compressor.
When the compressor is running, it can continuously compress the refrigerant and deliver the refrigerant to the evaporation box.
The refrigerant continuously expands and absorbs heat in the evaporator box, causing the refrigerant to cool the evaporator box.
The cooling evaporator box can cool the air blown by the blower, so that the empty air outlet of the car blows cold air.
The refrigerant used in automobile air conditioners is r134a, and the refrigerant needs to be added regularly in automobile air conditioners. If refrigerant is not added for a long time, the cooling effect of the car air conditioner will become worse and the cooling speed will slow down.
Therefore, it is recommended that you regularly add refrigerant when using your car.
When you use your car, you must also clean the car's air conditioning system regularly.
If the car's air conditioning system is used for a long time, it will breed a lot of bacteria. If it is not cleaned for a long time, it will affect the health of the passengers in the car.
