What should I pay attention to when using a car air conditioner in summer?

Entering July, it is the hottest time of the year, let's talk about the use of in-car air conditioning needs to pay attention to today. Let's talk about it first, how to turn on the air conditioner, some people say that there is no air conditioner? Of course, the AC switch must be turned on when the air conditioner is turned on in the car, and only the fan is turned on to blow the air, which is not cooling, and some people say that my air conditioner is not cool!

As a result, the AC switch was not pressed.

Is there a suitable time to turn on the car air conditioner? Yes, in summer, regardless of whether your car is sunburned or not, after the vehicle starts for more than ten seconds, let the engine speed stabilize a little and you can turn on the air conditioner. At this time, the air volume is increased, and all the windows are lowered.

The wind can blow dirt and harmful gases out of the pipes. If the car is sunburned, the temperature inside the car will be higher than the outside, and when the windows are opened, the hot air in the car will go out of the windows to shorten the cooling time of the air conditioner.

Some people on the Internet say that a car door can cool down quickly, this behavior is particularly incredible, there have been experiments before, a strong man fanned the car door for a long time, a measurement of the temperature in the car dropped less than two degrees, with the way of cooling the air conditioner, 2 minutes to solve the problem, we buy a car is to let the car service us, why do you not believe in your car?

When to turn off the air conditioner in your car? Turn off the AC switch two or three minutes before you are about to reach your destination, but keep the air volume on and continue to blow the air. The purpose of this is to allow the air to dry the aircon evaporator box and prevent the growth of bacteria.

Regarding the use of internal and external circulation of automobile air conditioners, it should be noted that external circulation is used when the air outside the car is used to allow fresh air from the outside to enter the car; Poor air quality outside the car is circulated internally to prevent bad air from entering the car.

Regarding the odor of the air conditioner, this is generally caused by the dirty core of the air conditioner or the dirty evaporation box. The treatment method is that you can replace the air conditioner core first, and if the odor is still there, 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.

What if there is not enough refrigeration? First of all, check the air conditioner core to see if it is dirty, and dirty air conditioner core will also affect the air output. In addition, if the car is old, it is necessary to check whether the condenser is blocked, and the condenser will affect the heat dissipation, in which case the condenser needs to be cleaned.

If both of these are okay, it's time to check if the refrigerant is sufficient.

Finally, let's talk about what to pay attention to when blowing cold air in the car, according to the principle of cold air sinking, the air conditioning air should blow upwards or horizontally, that is to say, the air outlet is adjusted to the most appropriate direction of horizontal or slightly upward blowing, but do not blow directly at the driver. If it's blowing downwards, it may feel a little hot, and the wind will blow in vain.

No matter what, you can't warm yourself!

Be sure to check the air conditioner for summer cars.

1. After getting in the car, open the windows for ventilation first

After the car is exposed to the sun, do not drive in a hurry after getting into the car, open the four doors first, and ventilate to emit toxic gases.

2. After starting, turn on the fan first

After starting the vehicle, turn on the fan and do not turn on the air conditioner (do not press the A C button). Let the fan blow away the polluted air in the air conditioning system, and at the same time blow away the hot air in the air conditioning system.

3. Turn on the air conditioner after 5 minutes of natural wind

Start the fan to blow the natural wind for 5 minutes, then press the air conditioner button to turn on the air conditioner to refrigerate. At this point, the windows should be left open all the time.

4. After the air conditioner is cooled for 1 minute, close the window

Some car owners are accustomed to turning on the air conditioner before getting into the car, and when the temperature in the car cools down, they drive directly on the road. At this time, formaldehyde and other toxic substances in the car cannot be volatilized, and all are inhaled into the body, and in the long run, various diseases will break out.

Therefore, when the owner enters the car, he should first open the window for ventilation, and then turn on the air conditioner after the toxic substances are released. At the same time, riders can also put some activated carbon packets in the car, which also has a certain adsorption effect on toxic substances.

5. Turn off the air conditioner 5 minutes before parking

It is best for car owners to turn off the air conditioner and turn on the natural wind 5 minutes before arriving at the destination. This can make the temperature in the air conditioning duct rise before parking, let it return to normal temperature, and ensure that there will be no condensation in the air conditioning duct due to the temperature difference after parking, so as to ensure the dryness of the air conditioning duct and block the breeding of mold and fungus.

Be sure to check the air conditioner for summer cars.

In the summer, when sleeping with the air conditioner in the car, you must pay attention to these points to keep you away from danger.

When the car turns on the air conditioner in the summer, you must first ventilate the car before turning on the air conditioner. Of course, when you turn on the air conditioner, be sure to remove the moisture.

For example, if the vehicle is running and the air conditioner is on, do not open the window and turn on the air conditioner. Don't set the temperature too low.

Do not close the window for a long time and open the internal circulation, which will make your car contain less and less oxygen, which will make you sleepy, thus causing driving hazards. It is recommended to cycle the inner and outer circulation alternately, and it is recommended to open a little window for the long use of the inner cycle.

What should I pay attention to when turning on the air conditioner in the summer? Before getting on the car during the time of sun exposure, the window should be opened to let it breathe, so that the air conditioner will be turned on, and the cooling effect will be better.

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.

Hello, the correct way to use the air conditioner is to turn off the air conditioner before turning off the engine, use yes, the air conditioner should not be turned on to the maximum, you can.

In summer, the temperature difference between the inside and outside of the car is large, when entering the car, it is not advisable to turn on the air conditioner temperature too low, you can first use a large air volume natural wind to blow away the heat in the car, and then do not close all the windows, turn on the air conditioner, and turn on the wind speed after the body gradually adapts.

Turn off the heat, turn on the windshield, and turn on the AC

Summer is coming, how to use the air conditioner correctly?

The correct use of a car air conditioner is as follows.

1. Turn on the AC switch, adjust the air outlet selection knob, blow the air outlet up when the cold air is turned on, and blow the air outlet down when the warm air is turned on;

2. Adjust the wind speed switch, and put the wind speed switch in the low speed gear when the speed is low, so as to avoid insufficient power generation and insufficient air conditioning;

3. Adjust the internal and external circulation of air, open the window for ventilation when you first enter the car, and turn on the external circulation to remove the hot air, and replace it with internal circulation after the temperature in the compartment drops;

4. Adjust the knob for switching between cold and warm. Automobile air conditioning refers to the air conditioning device installed on the car, which can refrigerate, heat, ventilate and purify the air in the cabin, provide a comfortable riding environment for passengers, reduce the fatigue intensity of the driver, and improve driving safety.

When using the air conditioner for an hour, you must open the windows to ventilate the car for ten minutes, which can avoid the increase in carbon monoxide concentration in the car, which affects people's health and driving safety.

1. Open the window first and then turn on the air conditioner.

Therefore, we can usually find that the first action of many car owners when they get into the car is to turn on the air conditioner. In fact, this will bring hidden dangers to people's health. Experiments have confirmed that after the car is exposed to the sun, the interior of the car will emit carcinogenic gases such as benzene and formaldehyde.

At this time, if you turn on the air conditioner as soon as you enter the car, you may inhale these toxic gases.

The correct way is not to immediately enter the car after exposure to the sun, or after entering the car, instead of rushing to turn on the air conditioner, first lower all the windows or open the door, then turn on the fan to accelerate the air circulation, and then close the window and turn on the air conditioner after a few minutes. This not only allows the toxic substances to be released, but also cools down better.

Second, the correct way is to choose to blow diagonally upward, so as to use the law of hot air rising and cold air falling, so that the cold air can cool down the car from top to bottom.

3. Don't keep your temperature low for a long time.

In addition, in the process of driving, the owner should also pay attention not to blindly covet coolness, and adjust the temperature of the air conditioner in the car to a very low level. Otherwise, people are prone to endocrine disorders due to too much temperature difference between inside and outside the car, making them more likely to get sick. In addition, turning on the air conditioner temperature very low will also lead to an increase in the fuel consumption of the car and increase the cost of the car.

In fact, under normal circumstances, it is best to have a difference of about 6 between the temperature inside the car and the outside temperature.

Fourth, if the owner is driving for a long time, it is necessary to make full use of the internal and external circulation function of the air conditioner. Some new car owners may not know very well, in fact, the internal and external circulation function is to control the air quality in the car, as well as the role of auxiliary heat preservation. Therefore, the car owner knows how to choose according to the bad environment in which the vehicle is located, for example, the vehicle is in the downtown area of traffic jams, in order to avoid the car exhaust gas entering the car, the owner can use the air conditioning internal circulation function, so as to ensure that the air in the car is not polluted.

5. Turn off the air conditioner before turning off the heat.

The last point is that many people are used to getting out of the car without turning off the air conditioner and turning off the engine directly. As everyone knows, although this is very convenient, the damage to the air-conditioning compressor is very large, and it is easy to breed bacteria in the air-conditioning air duct over time. The correct way is to turn off the vehicle's air conditioning compressor, that is, the AC button, about 5 minutes before the vehicle arrives at the destination, let the blower continue to work, dry the water vapor in the air duct, and then turn off the blower after arriving at the destination.

This can effectively reduce the working pressure of the air conditioning compressor and prolong the life.

The car is exposed to the scorching sun for a long time, and the small and closed compartment will lead to poor air flow in the car, and after a long time of continuous "baking" by the scorching sun, the temperature in the cabin is much higher than the outdoor temperature.

If you open the car door at this time, there will be a wave of heat in an instant... When many people encounter this situation, they will immediately start the car, turn on the air conditioner, and adjust the wind speed to the maximum to achieve the fastest cooling effect. In fact, this not only does not quickly reduce the temperature in the car, but also wears down the engine to a certain extent.

Generally speaking, after the car is started, the tachometer needle tends to climb to a higher rev all at once, and then drop to a relatively stable rev after a few seconds. If the air conditioning compressor is turned on just after starting, it will increase the load on the engine, which can damage the engine for a long time.

Therefore, the correct approach should be to open the four windows first, so that the air can be convection, so that the temperature in the cabin is equal to the outside temperature as soon as possible. When the engine speed is stable, close the windows and turn on the air conditioner, which will not damage the engine and quickly reduce the temperature in the car.
