Car “cold” knowledge ~ unexpectedly 50% of car owners don’t know? | The electric wave that never disappears

In most ofcarThere are two buttons on the air conditioner panel,

They represent the inner loop and outer loop respectively,

Do you know how to use them correctly?

Today I will give everyone a popularization.

When the air conditioner is turned on orfanAfter that, the air in the car has two circulation modes: inner circulation and outer circulation.

The internal circulation will block the entry of dirty gas outside the car, and only circulate the air in the cab.

The external circulation allows air from outside the car to enter, increasing air circulation.

Knowing these two points, we can use the inner loop and the outer loop according to different situations.

When the weather is hot in summer, we must first turn on the external circulation after turning on the air conditioner.

After allowing the dirty air in the car to flow out and the temperature of the air conditioner is lowered, switch to the internal circulation.

Because the use of internal circulation has a better effect on air conditioning and refrigeration, it will prevent the hot air outside the car from entering.

Some people may complain that the cooling efficiency of air-conditioning is not good in summer, so you might as well see if you have turned on the external cycle.

Of course, when driving for a long time, the inner loop cannot be used for a long time.

Especially when there are many people in the car,

Long-term use of the internal circulation will make the air in the car muddy and make the driver feel uncomfortable.

At this time, you can turn on the outer circulation for a certain period of time to let in fresh air, and then switch to the inner circulation.

in addition,

According to the characteristics of the internal circulation that can block the dirty air outside the car,

In congested road conditions, when surrounding cars have more exhaust or are following behind vehicles with high exhaust pollutants such as trucks, the internal circulation should also be opened to prevent harmful gases and odors from entering the car.

When the warm air is turned on in winter,

If the internal circulation is turned on for a long time, the air in the car will be too dry.

Not suitable for comfortable driving.

At this time, the outer circulation can be opened to let the cold air from outside the car enter the car.

In this way, a comfortable temperature in the car can be maintained and the members can still breathe fresh air, achieving two goals with one stone.

and also

We should form a good habit,

It means opening the window to ventilate when you first enter the car,

Let the stale air in the car exhaust as soon as possible,

Let in fresh air,

In this way, the internal circulation cooling/heating can be quickly utilized.

In the first 6 months of buying a new car,

In order to accelerate the volatilization of formaldehyde in the car,

Long-term ventilation and external circulation should be used,

Reduce the damage of harmful substances to the members in the car.

Well, the above is the correct way to use the inner and outer loops, have you learned it?
