How to use the car air conditioner correctly in the hot summer

In the hot summer, the natural use rate of on-board air conditioning is extremely high. However, some car owners will worry that the air quality in the car is too poor or that turning on the air conditioner will cost special fuel, so I will answer your questions today.

In summer, the smaller the air conditioner in the car, the more fuel-efficient it is?

Most car owners think that it will be more fuel-efficient to turn on the air conditioner to the maximum gear, so just turn on the light wind! In fact, air conditioners tend to suck in a certain amount of dust during use, which is easy to mildew after a long time, and it is easy to accumulate dust when blown by a small wind for a long time, so it is okay to open a bigger one, but it is good for health! There are many drivers who are reluctant to turn on the air conditioner in order to save fuel, in fact, the compressor of the general car air conditioner is a fixed displacement, so no matter whether you turn up the temperature or reduce the air volume, the engine is the same rotation, so the air conditioner is the same fuel consumption.

However, there are variable displacement compressors in mid-to-high-end cars, which can indeed save fuel, but it seems that people who can afford this kind of car do not care about the fuel money generated by air conditioning!

How can I cool down the temperature in my car in the shortest possible time in summer?

If the temperature in the car is higher than the outdoor temperature, it is recommended that the drivers roll down the window on one side before getting into the car, and use the door on the other side to blow a few times to drop about ten degrees, and then open the external circulation, blow the fan blades of the air conditioner upward, and then open the inner circulation when the temperature drops, so that the temperature decreases the fastest!

Replace the air conditioner filter regularly to keep your car air conditioner in the best condition!

In the summer, you can sometimes find that the wind blowing from the air conditioner of the vehicle has an unpleasant smell. Therefore, at this time, the air conditioner filter should be replaced, and the filter element should be replaced once every six months. In addition, there are 1,000 to 2,000 molds per square centimeter on the evaporation tank of the car air conditioner that has not been cleaned for three years, which has to be maintained in the store!

In addition, some sloppy drivers will forget to turn off the air conditioner when they stop the engine, so that the air conditioning system of the car will mildew after a long time, because the water vapor in the evaporator cannot be excluded, so it is best to turn off the air conditioner a few minutes before stopping and turning off the engine.

Before using the car air conditioner in summer, you must do a detailed inspection or cleaning of the air conditioning filter, evaporation tank, and condenser, which can not only ensure the normal use of the air conditioner, but also prevent potential safety hazards to the health of the driver.

Pipe cleaning, open the window before turning on the air conditioner, temperature modulation 25 is the best, and the opening time should not be too long, etc.

When the air conditioner is used frequently in summer, a lot of dirt, dust, and bacteria will grow in the air conditioning duct, which will affect human health, and the air conditioning duct must be cleaned regularly.

If the car is parked for a long time in the hot sun, do not use the air conditioner immediately after the vehicle is started. All windows should be opened first, the external circulation should be started, the hot air should be exhausted, and the windows should be closed after the temperature in the cabin has dropped.

The most suitable air conditioning temperature for the human body should be between 24 and 27, the minimum should not be lower than 22, and the temperature difference between the inside and outside of the car should not be greater than 5. If the air conditioner is turned on too much and the temperature in the car is too low, it is easy to cause arthritis, frozen shoulder, cold, diarrhea, fever, lack of energy, etc. It is generally recommended that the temperature of the air conditioner in the car be controlled at about 25.

Using an air conditioner for a long time can cause excessive condenser pressure, which can cause wear and tear on the refrigeration system. So, if the temperature inside the car is already comfortable for you, turn off the air conditioner for a while and let it rest for a while.

The principle of air outlet of automobile air conditioner: turn on the air outlet upwards when the air conditioner is turned on, and turn the air outlet down when the heating is turned on.

1.Don't rush to turn on the air conditioner as soon as you get in the car.

This is mainly for cars that have been parked for one night or for a long time, because if they are left for too long, the air in the closed car will become turbid, and if it is a new car, there may be harmful gases. It is best to open the windows first, then open the external circulation, blow all the air in the car, and then close the windows and turn on the air conditioner.

The same is true for cars after sun exposure. The air temperature in the car is very high after exposure to the sun, and if you turn the air conditioner to the maximum as soon as you get in the car, the temperature will drop very slowly. If you blow the stuffy air away before turning on the air conditioner, the temperature in the car can quickly cool down.

2.The air conditioner should be used for internal and external circulation.

If we use the internal circulation for a long time, then the air will only circulate in the car, and it doesn't matter if we drive for a short distance, but if we use the internal circulation for a long time, it will make the people in the car feel stuffy and uncomfortable. This is what suffocates the air that does not circulate. At this time, as long as you open the external circulation and let the outside air in, you will feel a lot.

Nowadays, many car automatic air conditioners will automatically switch between internal and external circulation, such as 20 minutes of circulation and then 2 minutes of external circulation, so as to prevent passengers from stuffing. However, if your car is driving in a congested city, if you turn on the external circulation, the gas transferred may not be as good as the inside of the car. Therefore, it is recommended that you go to the section where the air is relatively fresh and then open the external circulation.

3.It's best to turn off a c in advance

A c is the switch of the air conditioner compressor, and the air conditioner will only be cooled when the air conditioner is turned on, otherwise the air conditioner will only supply air. When the A C button is turned on, the refrigeration equipment of the car will be running, and the moisture generated by these devices while they are running. Coupled with the sultry environment of the engine compartment, it is very suitable for the growth of mold, bacteria.

Over time, the air conditioner will produce peculiar smells, sour odors, etc. So every time you are almost at your destination, turn off a c, and then add a little air volume to let the air dry the pipes a little, so that mold is not easy to grow.

4.Use hot air to defog the windshield.

In autumn and winter, the glass will often fog up, and at this time we can use the defogging function of the car. With the defogging function, the front windshield air outlet will open, and if the air conditioner is blowing cold air, it can be dehumidified and defogged through the cold air. But sometimes the weather is already cold, and the cold wind really freezes to death.

At this time, you can use hot air to defog. However, the defogging speed of the hot air is relatively slow, and it will take a while for the hot air to have the effect of defogging. Therefore, it is recommended to park on the side of the road for a period of time before hitting the road, and at the same time, you can open some windows to accelerate the air circulation in the car, and the temperature difference between the inside and outside of the car is small, and there will be no fog naturally.

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, before entering the car in summer, first drop the four door glass to let the hot air flow out quickly, and then turn on the air conditioner, close the glass, I am very happy with your problem, I hope it can help you, I wish you a happy car!

Summer is coming, how to use the car air conditioner correctly? I don't know how to suffer!

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.

Correct use methods and skills of car air conditioners in summer:

1 Prevent the ingress of unclean air If the car is driving on a dusty road, the air inlet should be placed in the inner circulation position to prevent dust from entering the car.

2. When it is hot, the windows should be opened first to allow the hot air in the car to be discharged naturally; The air conditioning system is most efficient when the windows are closed. However, if the car is parked in the sun for a long time and it is very hot in the car, after turning on the air conditioner, a glass window should be opened and then closed after the hot air in the car is discharged.

3 When the engine is under heavy load, the air conditioner should be temporarily turned off When the engine works for a long time under heavy load in the hot season, it should have a good cooling effect, and in order to prevent the engine from overheating, it should be temporarily closed and closed. Otherwise, once the engine overheats, it will not only affect the driving of the car, but also affect the use of air conditioning.

4 Reasonable selection of air conditioning wind speed gear In the normal operation of the car, in order to prevent excessive frosting of the evaporator and affect the operation of the air conditioning system, the air supply speed and temperature control of the air conditioner should not be kept to the lowest for a long time. However, when the speed is lower than 25kmh, the wind speed switch should be set to the low speed gear to avoid insufficient power generation and insufficient air conditioning.

5 Master the starting procedure of the engine For the automobile air conditioning system without automatic speed control device, the engine should be started first and then the air conditioner should be turned on when used to avoid difficulty in starting.

6 When the air conditioning effect is poor, the air conditioner should be turned off and checked in time When the cooling effect of the air conditioner is poor, it indicates that the system is working poorly, and turning off the air conditioner in time can prevent the expansion and deterioration of the fault, which is very important to protect the air conditioner and prolong the service life of the air conditioner. If the air conditioner fails, it should generally be repaired by professionals. In the season when the air conditioner is not in use, the air conditioner should be left working for a few minutes every 2 to 3 weeks to keep the system in good working order.

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?

When driving on the road, the easiest season to use air conditioning is summer, summer is dry and stuffy, even people stay indoors feel very uncomfortable, feel extremely hot, not to mention the car, the car stays outside after an afternoon of sun exposure, the temperature in the car can reach up to 60
