Yes, a car can turn on the external circulation without turning on the AC. The external circulation and AC are two completely different mechanisms with no connection between them. The differences between external circulation and AC are as follows: 1. The car's external circulation uses a fan to draw outside air into the car, allowing passengers to breathe fresh air from outside. The external circulation means that the air passages between the outside and inside of the car are interconnected. The air from the car's fan comes from outside, and even if the fan is not turned on, airflow is still drawn into the car while driving, replenishing the fresh air inside. 2. The AC is the switch that controls the air conditioning. To cool the car, the AC switch must be turned on. AC stands for Air-Conditioner. The car's AC button controls the compressor. The AC switch controls the electromagnetic clutch, and for the car's compressor to operate, the electromagnetic clutch must be turned on while powered. Only after the compressor is turned on will the car start blowing cold air. 3. The external circulation is mainly used when the air inside the car becomes stale. For example, when smoking inside the car, turning on the external circulation ensures fresh air inside. In summer, the AC button is used to turn on the air conditioning to cool the car.
