Car evaporator: one is a heater tank, and the other is an air conditioner.

After the water in the car's water tank is hot, it flows into the warm air water tank, and the wind blown out by the fan is the warm air.

When the cooling is turned on, the water inlet of the warm air tank will stop, the air conditioner will start to operate, and the compressor will press the refrigerant into the air-conditioning sheet, and the natural wind will blow out.
