In general, there is an area on the central control panel of an automobile that is specially used to control air conditioning, that is, the air conditioning control panel.
Automobile air switch is a very important comfort configuration in automobile. The cooling principle and heating principle of air switch are actually very simple.
The air conditioning button of the car is empty, it is a cooling switch. When the air conditioning button is pressed, the compressor clutch will engage. At this time, the engine will drive the compressor to run, and the compressor will continuously compress the refrigerant and transport it to the evaporation box.
The refrigerant expands in the evaporation box to absorb heat and cool the evaporation box, and then the evaporation box cools the air blown by the blower, so that the air outlet blows cold air.
When heating, the high-temperature coolant in the engine will pass through the warm water tank, and the air blown out by the blower will also pass through the warm water tank, so that the air outlet can be adjusted to blow out warm air.
When heating, you can work without pressing the air conditioning button or compressor. Heating has nothing to do with compressor, refrigerant and evaporation box.
When replacing vehicles/refrigerants, you need to go to a specialty store to replace professional household equipment.
