How to use the internal and external circulation of automobile air conditioner

Internal circulation: turn on the in-car air conditioner, ensure that the ac button remains on, turn on the inner circulation button in the car, and keep the inner circulation button indicator light on; external circulation: press the one-button start button, start the engine, press the auto button, turn on the automatic air conditioning system, press the outer circulation button, and turn on the outer circulation mode.

The internal and external circulation of car air conditioners is very simple to use. There is an internal and external cycle switching button on the control panel of the car air conditioner, which can be switched. When driving on congested urban roads, it is recommended to use the internal circulation mode, and for driving on some long-distance sections or highways, it is recommended to use the external circulation mode.

When to use the external circulation? The new car you just bought must open the external circulation as much as possible to maintain the air circulation inside and outside the car, so that the harmful gases in the car can be released as soon as possible.

Do you know the difference between the internal and external circulation of cars?

1. The difference between in-vehicle circulation and external circulation: internal circulation refers to the air in the car after heating or cooling in the car; external circulation refers to the heating or cooling of the air outside the vehicle and sending it into the car, that is, the gas exchange inside and outside the car.Internal circulation means that the/icon is an arrow circulating in a closed car.

2. External circulation refers to the air inhaled from the outside of the car, introduced into the air conditioning system for heating or cooling, and then blowing out from the air outlet. External circulation is actually to supplement fresh air and improve the quality of the air in the car.

3. The internal circulation is to let the gas in the car circulate repeatedly when it is closed. The sign is a closed car with a repeated arrow symbol inside; while the outer circulation is to circulate the gas outside the car into the car. The logo is a non-closed car, and there is a gas arrow symbol pointing to the car outside.

4. Internal circulation: the air only circulates in the car and does not communicate with the outside air; external circulation: the air in the car is connected to the outside air, and the outside air flows in from the forward airway of the car and flows out from the rear air outlet of the car.

5. The difference between the external cycle and the in-car circulation is the working principle and purpose, etc. Working principle Internal circulation refers to the air in the car after heating or cooling in the car and then sent back to the car; external circulation refers to the heating or cooling of the air outside the car and sending it into the car, that is, gas exchange inside and outside the car.

Is there a division between "inside and outside" in the car blind area?

The blind spots in the car mainly include four major visual blind spots and some artificial blind spots. Four major visual blind spots: the front blind spot. The place that cannot be directly observed in front of the hood is called the anterior blind area.

Car front blind area When children squat down and play in the front blind area, they can't see in the cab, which is easy to cause accidents. It should be noted that, the body of the SUV is larger than that of a small car, and the front of the car is also higher than that of a small car, so the cover area and blind spot are larger, and drivers should pay special attention to it.

Secondly, there is the A-pillar blind area. The blind area on the left side of the car is much smaller than that on the right side, that is, the blind area on the right side will be larger. Therefore, in order to avoid traffic accidents, drivers must pay more attention to the left and right sides when driving.

The blind area can be roughly divided into "fixed" blind spots in the car and "moving" blind spots outside the car. Generally speaking, in the stationary state, the blind area mainly includes the front blind area, the rear blind area, and the blind area formed by the ABC column; in the process of driving, there are also corresponding blind areas when overtaking, waiting and turning.

The specific operation of the internal circulation and external circulation is as follows: the function of the external circulation is to replenish the fresh air in the vehicle, while the internal circulation keeps the dirty air out. External circulation is used to introduce external air into the vehicle. The airflow in the circuit only comes from the vehicle, forming an air circulation inside the vehicle.

Internal and external circulation, as the name implies. Internal circulation is to let the air circulate only in the car, and drive the air in the car to circulate through the blower. External circulation is to connect the inside of the car and the outside world. During the driving process of the vehicle, the airflow will automatically suck into the car using the wind pressure. When it is stationary, the air outside the car can also enter the blower along the airway, thus blowing into the car.

The function of external circulation is to let the fresh air outside the car flow into the car and ventilate the inside of the car. The wind from the fan comes from the outside of the car. Even if the fan is not turned on, there is still airflow inhaled into the car while the vehicle is driving to replenish the fresh air in the car. Sometimes I feel that there is still wind when the fan is turned off, because the owner has set up the external circulation.
