Are you really using the air conditioner in the car?

1. How to turn on the air conditioner correctly.

Turn on the air conditioner must turn on the A C switch, this is the switch of the compressor, only turn on the blower to blow the air conditioner is not refrigerated, there are really many drivers who do not know to turn on the A C switch.

2. When to turn on the car air conditioner.

Regardless of whether the temperature in the car is very high, or the vehicle is parked in the garage and is not sunburned, after the vehicle starts for more than ten seconds, the air conditioner can be turned on immediately after the engine speed stabilizes a little. At this point, you can increase the air volume and lower all four windows. The large air volume can blow out the dirt and harmful gases in the pipeline.

If the car is exposed to the sun, the temperature in the cabin is higher than the outside, and after opening the window, the hot air in the cabin can also go out of the window, which can shorten the cooling time of the air conditioner. This process does not take too long, about a minute or two, after which you can close the windows and turn on the air volume to the right place.

3. When to turn off the car air conditioner.

Our advice is to turn off the AC switch of the air conditioner two or three minutes before arriving at the destination, and leave the air volume switch off at this time, so that the blower can continue to blow air. The purpose of this is to allow the air to dry the air conditioner's evaporation box and prevent it from growing bacteria. If mold is produced in the evaporation tank of the air conditioner, it will deteriorate the interior environment.

4. The use of internal and external circulation of automobile air conditioners.

When the air outside the car is ***, the external circulation is used to let the fresh air from the outside continue to enter the cabin, so that the air in the compartment is kept fresh; The poor air quality outside the car is circulated internally to prevent bad air from entering the cabin. It is worth noting that when the wind blows the position of the glass, the system automatically switches to the external circulation mode, which is not a fault phenomenon.

5. About the smell of air conditioning.

The odor of the air conditioner is generally caused by the dirty air conditioner core or the dirty evaporation box. The treatment method is that you can replace the air conditioner core first, and if the odor still exists, you need to clean the air conditioner evaporation box. The car air conditioning core should be replaced at least twice a year, once in winter and once in summer.

6. What's going on with insufficient refrigeration.

First, if the refrigeration effect of the vehicle is worse than before, the air conditioning core should be checked first to see if it is dirty. Second, if the car is older, you should check whether the condenser is blocked, if the condenser is blocked, it will affect the heat dissipation, and it will also lead to poor refrigeration effect, in this case, you can clean the condenser. Third, there is no problem with the above, to check whether the refrigerant is insufficient, which requires special testing equipment.

It is worth noting that the cooling effect of different models is different, and if the cooling effect of the model itself is not good, then there is no solution.

7. Which direction should the wind blow?

According to the principle of cold air sinking, the air conditioner should blow upwards or horizontally, that is to say, it is best to adjust the air outlet to the direction of horizontal or slightly upward blowing, but do not blow directly towards the driver. If it blows downward, the person in the back seat may feel hot.

In fact, there are many skills in using car air conditioners, although it is just a few simple buttons, but the combination is very different.

The temperature inside the car can reach 50 when exposed to the sun outdoors. Every time I just got in the car, the owner was tormented. Even if you turn on the air conditioner, it can be a bit difficult to cool the 50 hot air by the air conditioner alone.

You can only feel the chill of the air outlet, and the back of your hips against the chair is still hot.

In fact, before getting into the car, open all the windows or doors to let the heat out, and you will feel much better. Then open the glass, open the sunroof with a sunroof, open it for a while, let the heat out, and then close the window, you will feel that the air conditioning effect is much better.

<> "Do You Really Use Car Air Conditioners?" These are the big mistakes that veteran drivers will also make.

Myth 1: Always laugh at the internal circulation mode.

When the air conditioner's internal circulation mode is turned on, the air exchange inside and outside the vehicle will be stopped. The air outside the car cannot enter the car, and the air inside the car cannot be exhausted from the car. Using this mode for a long time is easy to cause poor air circulation, and drivers and passengers are prone to feel dizzy and chest tightness, which affects the comfort of riding.

In severe cases, it can still lead to carbon monoxide poisoning in drivers and passengers, threatening life and health.

Therefore, when driving in summer, the owner should recycle the internal and external circulation, do not keep the internal circulation, and pay attention to the circulation of air inside and outside the car.

Myth 2: Turn on the air conditioner immediately after the car is exposed to high temperatures.

In the summer, not all car owners choose to park their car in the underground parking lot. Some car owners park their vehicles in open parking lots for other factors such as saving time and trouble. When their car is exposed to the sun, some car owners will immediately turn on the car air conditioner.

In fact, this method is very wrong, and it is easy to increase the load on the vehicle's engine and shorten its service life.

The correct thing to do is that the owner should first open the windows or doors to let some of the heat in the car dissipate. When the owner feels that the temperature in the car has dropped significantly, he can close the windows and doors, and then turn on the air conditioning.

Myth 3: The wind direction is adjusted at will.

After the car air conditioning is turned on, the temperature in the car will be reduced to a certain extent, making the driver and passengers feel cool. However, some car owners will adjust the wind direction at will after turning on the air conditioner, or even adjust each air conditioning outlet to different directions, trying to accelerate the reduction of the temperature in the car in this way.

Actually, this way is not advisable. Because cold air is heavier than hot air, if you want to cool down the interior of the car faster, you should turn all the air vents upward.

Myth 4: Turn off the air conditioner after turning off the engine.

Once you reach your destination by car, you naturally need to stop. Before parking, some car owners will not turn off the air conditioner in advance, but choose to turn off the air conditioner after turning it off. In fact, this way of using the car is very wrong.

This method can easily lead to the multiplication of mold in the air conditioner, which will affect the normal use of the air conditioner, and at the same time will cause odor in the car, affecting the mood and health of passengers.

The correct way to do it is that the owner should turn off the air conditioner in time before parking. In addition, the owner of the car should open the windows properly to allow the air in the car to circulate for a while, and Li Tsai will restore the air-conditioning system to a relatively dry state, which will destroy the conditions for the growth of mould before turning off the engine and stopping the car.

<> "A little knowledge about car air conditioning, will you use it?"

1. Is the air conditioner outlet up or down?

The principle that hot air rises and cold air dissipates quietly. Everyone should also grasp this rule when turning on the air conditioner in the car, turning the air outlet up when turning on the air conditioner, and turning the air outlet down when turning on the heater.

2. Clean frequently and replace the air conditioner filter regularly.

Many car owners often wash their cars, but they don't pay attention to the maintenance of their cars. In summer, there are often heavy rains and humid weather, and if you do not clean the air conditioner in time, it will cause peculiar smell and musty smell in the car.

3. Occasionally open a strong wind gear.

During the use of the air conditioner, occasionally turn on the maximum air volume gear, which can blow out the residual floating dust in the air duct.

4. How to use internal and external circulation.

Internal circulation, external circulation, stupid and unclear! When the car is hot, we need to use the external circulation to release the hot air in the car, and then wait for the temperature to drop almost before turning on the air conditioner and the internal circulation at the same time.

5. The air conditioner also needs to rest.

Many friends will run the high-speed will be all the way to the air conditioner, in fact, this will make the condenser pressure of the air conditioner too large, long-term air conditioning will seriously damage the refrigeration system, it is recommended that you open the window for a while, open the window for ventilation, good for the body, good for the car.

6. Fluoride should not be underestimated.

Don't feel cool when the air conditioner is turned on to the highest setting? It is likely that the lack of fluorine affects the heat dissipation of the system, resulting in the air conditioner not cooling.

7. Turn on the air conditioner every week.

Turn on the air conditioner almost every day in summer, but what about winter? Turn on the cold air 3-4 times a month for 5 minutes each time, which can effectively prevent the aging of the evaporator and compressor.

Eight misunderstandings about the use of car air conditioners

Myth 1: Turn on the air conditioner immediately when you get in the car

When the car is just started, the engine has not yet reached a good state, and turning on the air conditioner at this time will increase the load on the engine. It is recommended to fan the door several times before getting into the car, turn on the fan and open the front liquid window after getting into the car, turn on the air conditioner after 5 minutes, and close the window after 1 minute of air conditioning.

Myth 2: As soon as the air conditioner is turned on, the internal circulation is turned on

Turn on the external circulation of the air conditioner first, and then the internal circulation. The temperature inside the car is higher than the temperature outside the car, and opening the internal circulation is not conducive to the hot air in the car. Circulate.

On the contrary, opening the external circulation will make the air conditioning outlet temperature lower, and it can also lubricate the engine. You can wait for the temperature in the car to cool down, and then switch between the inner and outer circulation at regular intervals.

Myth 3: Turn on the air conditioner and wait for people to sleep after parking

This is a very dangerous thing, because when the engine is working, if the gasoline in the cylinder is not burned completely, a high concentration of carbon monoxide will be produced, which can lead to poisoning and even death.

Myth 4: The air conditioner is always turned on at the minimum air volume

The air conditioner will suck in a certain amount of dust during use, which will form dirt, and mildew will occur over time. If a small amount of wind is mainly used for a long time, it is difficult to blow out the dirt in the air conditioner. Therefore, every once in a while, you need to turn on the air conditioner to the maximum setting, about 10 minutes, which can effectively prevent dust accumulation.

Myth 5: Let the air outlet blow downward

As the hot air rises and the cold air sinks, the air conditioning wind blows downward, and the cold air is concentrated in the lower part of the cabin, and the air cannot be convection, so it will be relatively hot. It is recommended to place the air outlet facing upwards to cool down quickly and feel more comfortable.

Myth 6: Turn off the engine first and then turn off the air conditioner

Turn off the engine first and then turn off the air conditioner, the car will ignite with the pressure of the air conditioner when it starts next time, which will increase the burden on the engine, and at the same time, the air conditioning pipeline and air outlet are easy to breed bacteria. The correct way to do this is to turn off the air conditioner and then turn off the heat.

Myth 7: Don't clean the air conditioner for a long time

If the air conditioner is used for a long time, bacteria breed in large quantities, and if they are not removed in time, germs will blow into the human body with the air conditioner, causing respiratory infection. Moreover, if it is not cleaned for a long time, the refrigeration effect of the air conditioner will also decrease. It is recommended to regularly replace the air conditioner filter element and clean the air duct of the air conditioner, especially in cities with poor air quality.

Myth 8: Don't use air conditioning for a long time

Many drivers leave their air conditioners idle for long periods of time outside of summer, so that the air conditioner compressor is not lubricated enough, which may cause leaks in the pipeline. It is recommended to let the air conditioner run once a month.

<> "Misunderstandings in the use of air conditioners in cars.

1. Turn on the stove and stop the car to sleep with the air conditioner in hand.

The heat of summer makes people feel drowsy, especially in the afternoon, when the feeling of sleepiness is even stronger. In order to alleviate this fatigue, some drivers simply park their cars in the on-street parking lot, then turn on the air conditioner, close the windows tightly, and sleep happily. But this is very dangerous, because at this time the engine is in an idle and idling state, gasoline combustion is not completely produced high concentration of carbon monoxide, the human body will inhale it will cause poisoning, so you must not drive the air conditioner to stop and sleep.

2. Smoking in an air-conditioned vehicle.

Many car owners are very addicted to smoking, even if they have an air conditioner in the car, they have to smoke while driving. However, smoking in an air-conditioned car is very harmful to human health, and the doors and windows are closed when the car is air-conditioned, and the smoke generated by smoking cannot be discharged at all. For the passengers in the car, they must be exposed to secondhand smoke with you.

3. Turn on the air volume of the air conditioner to the minimum.

In order to save fuel, most car owners will turn on the air volume to the minimum when turning on the air conditioner. In fact, the air volume of the car air conditioner does not affect the fuel consumption of the car, so there is no need for everyone to do this. Moreover, the air volume of the car air conditioner is too small, and it is difficult to blow out the dirt in the air conditioner, which will affect people's health.

4. Turn the temperature of the air conditioner to the lowest.

In the summer, when the car is exposed to the sun, the interior of the car is as hot as a stove. In order to cool down the interior of the car quickly, many car owners will adjust the temperature of the air conditioner to the lowest. However, the low temperature of the air conditioning in the car not only can not play a role in rapid cooling, but the long-term low temperature environment will cause dizziness and headache and other uncomfortable symptoms, and the temperature of the air conditioning in the car is generally adjusted to about 26 degrees in summer.

5. Turn off the heat and then turn off the air conditioner.

In order to blow the air conditioner for a while, some car owners often turn off the air conditioner and then turn it off. However, the damage to the car engine is very large, because it will cause the car engine to start with the load of the air conditioner when it starts the next time. Therefore, everyone should turn off the air conditioner and then turn off the engine after parking the car every time, or turn off the air conditioner when you are about to reach the destination, so that the remaining cool air in the car can also cool the car for a while.

6. Always use the internal circulation.

Many car owners like to keep the internal circulation on when they turn on the air conditioner. However, this is not right, the car air conditioner can not be used for a long time, otherwise it will cause the air in the car to get worse and worse, which will cause certain harm to the human body. The correct way to use it is to first open the internal circulation for a while, and then open the external circulation for a while to let fresh air into the cabin.
