If you want to turn on the warm air of the air conditioner, you need to turn up the temperature and then choose the appropriate air volume. When using warm air, you don't need to press the air conditioning button. The ac button is the refrigeration switch of the automobile air conditioner.
The refrigeration and heating principle of automobile air conditioner is very simple.
If you want to cool the car air conditioner, you need to press the ac button. At this time, the compressor clutch will engage, so that the engine will drive the compressor to run.
When the compressor is running, it can continuously compress the refrigerant and transport it to the evaporation box, where the refrigerant expands and absorbs heat, so that the refrigerant cools the evaporation box.
The cooling evaporation box can cool the wind from the blower, so that the air outlet of the automobile air conditioner can blow out cold air.
The heating principle of automobile air conditioner is simpler. After the heating function is turned on, the high-temperature coolant in the engine will flow through the warm air box, and the wind blown by the blower will also pass through the warm air box, so that the air outlet of the automobile air conditioner can blow warm air.
The warm air tank is actually a heat exchanger. Without this component, the car air conditioner can't heat.
Automobile air conditioners need to use refrigerants, and most automobile air conditioners are using r 134a.
Refrigerant needs to be replaced regularly. If the refrigerant is not replaced for a long time, the refrigeration effect of automobile air conditioner will be poor and the refrigeration speed will be slow.
