How should the air conditioner of the car be turned on to minimize fuel consumption?

First of all, the temperature of the air conditioner should not be set too low, generally set to 25 degrees Celsius, too low temperature, not only easy to cause colds, but also easy to increase the load of the air conditioning compressor, it needs greater fuel consumption to drive, so the lower the temperature, the higher the fuel consumption. Second, just enter the car, do not turn on the air conditioner immediately, first open the window for ventilation, dissipate the hot gas, and then start the vehicle, wait for the engine to run for about 3 minutes, fully lubricate, and then turn on the air conditioner, which not only has low fuel consumption, but also has good health to protect the engine.

Third, when driving at high speeds, when the speed reaches 70 kilometers per hour, close the windows tightly and turn on the air conditioning. If the windows are wide open, fuel consumption is higher because of the huge wind resistance to be overcome. Fourth, don't stop without turning off the air conditioner.

Because when the engine is started again, the air conditioner starts at the same time, the engine load is large and the fuel consumption is high. It is best to turn off the air conditioner about 5 minutes before parking because it can keep the car cool for a while and save fuel.

Of course, the most suitable way is to open the windows first, use convection to let the heat inside naturally dissipate, and then turn on the air conditioner after a few minutes. Finally, of course, close the windows and open the inner circulation. In the same way, if you want to end the trip, it is best to turn off the air conditioner in advance, open the window, and let the natural breeze in, which can also keep it refreshing, because there is also a time process for the air conditioner to dissipate, and you can reach the end point during this time period, which is both fuel-efficient and cool.

As an added bonus, the windows let in the natural breeze and remove odors from the car. Second: how to explain that the wind can't blow blindly?

Our air conditioning outlet is used to adjust the wind direction, when cooling, it is best to adjust the wind direction to blow up, because the cold air is going down in the end, and the hot air is going up, so that the cold air meets the hot air in advance, which can play a refrigeration effect as soon as possible.

The air conditioner should be turned on to the middle position as possible, so that fuel consumption will be minimized and you can save money.

The first thing is not to turn on the air conditioner immediately after getting into the car, you should let the heat in the car go out first, and then do not open the windows when turning on the air conditioner when driving at high speeds.

Try not to turn on the lowest temperature of the air conditioner, just choose a medium position.

Try not to turn on the air conditioner at a temperature that is too low, and the wind speed is not too fast, which is better for fuel consumption.

The temperature of the air conditioner is set at around 25, and do not turn on the air conditioner as soon as you enter the car.

It's the best feeling when I drive it to about 25 degrees.

Don't set the air conditioner too low, and adjust the temperature of it appropriately within a range.

Naturally, it is necessary to turn down the air conditioner to the minimum when it is cool in the car.

When the car is very hot and cold, generally we have to adjust the temperature to the lowest high, but the air volume should not be adjusted to the maximum, generally the middle of the block on the line. When the temperature reaches a comfortable level, the manual air conditioner needs to be adjusted again to maintain a constant temperature in the car. Therefore, the birth of automatic air conditioning is to save the step of rapid temperature adjustment and re-constant temperature. ​

When turning on the air conditioner during the change of seasons, pay attention to dredge the vents.

The air conditioner is useless for a season, and the vents are often blocked by dust, so when you turn on the air conditioner, you should see if the vents are accompanied by foreign objects, etc., you can turn on the ventilation mode first and let the air conditioner blow the dirty things inside.

Timing the air conditioner.

In the hot summer, do not turn on the air conditioner when you just open the car door, especially if the vehicle is exposed to the sun, you should open the window for ventilation first, and then close the window and turn on the air conditioner after the temperature in the car is the same as the outside. In this way, the cooling time of the air conditioner can be shortened and fuel consumption can be saved.

Choose the air conditioning gear according to the number of people in the car.

When the number of people in the car is relatively small, such as less than 2 people, generally speaking, a gear air conditioner is fine, just don't sweat, don't adjust the temperature is too low, there is no need to open the high gear, otherwise it can only increase a lot of fuel consumption. When there are more people, you can increase the gear appropriately.

Adjust the wind direction of the air conditioner.

That's right, adjusting the air conditioner's wind direction can also save fuel. Generally, blowing straight forward has the best cooling effect, which is also the most fuel-efficient. However, if there are babies or pregnant women in the car, you can't blow it directly, which will hurt your body, so you should spread it to both sides or blow downward.

This blows slightly more fuel, but is better than blowing the front windshield. Ashini plum.

When the vehicle turns on the air conditioning, the power of the small displacement car will be significantly affected, the large displacement car can not feel it, the small displacement car should pay attention, do not step on the accelerator in order to pursue high power, which will increase fuel consumption, and the speed can not be improved. Refuel slowly according to the road conditions, and then deepen the throttle when the speed is up.

Turn off the air conditioner in advance when parking.

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 engine speed can be slightly stabilized and the air conditioner can be turned on. 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 circulated, the fresh air from the outside world continues to enter the compartment continuously, so that the air in the compartment remains 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 field height 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.

The correct way is to open the window first, and then increase the air outlet volume of the air conditioner, adjust it to the external circulation, drive out the hot air in the car, and then change it to the internal circulation, for the small displacement of the car, as long as the refrigeration and air conditioning are turned on, the AC stage will affect the power; It is necessary to maintain it regularly, clean the dust and impurities on it, and repair and maintain the air conditioning pipeline regularly.

When entering the car, you should first open the window for ventilation, exhaust the hot air, and then turn on the air conditioner, determine the appropriate air conditioning gear according to the temperature in the car, check the air outlet of the air conditioner, and pay attention to preventing the vehicle from being driven by the air conditioner.

When the air conditioner is turned on for 5 hours, after playing the car, wait for the engine speed to be stable and then turn on the air conditioner, try to blow the air outlet upwards when the air conditioner is turned on, so that it will soon become cool in the car, the car is better to open the air conditioner above 70 kilometers, and open the window to blow the natural wind below 70 miles.

When entering the car, you should first open the window for ventilation, exhaust the hot air, and then turn on the air conditioner, choose the appropriate air conditioning gear according to the temperature in the car, check the air outlet of the air conditioner, and pay attention to avoid starting the vehicle with the air conditioner on.

When driving, it should be driven according to the road surface, if it is an ordinary road, you should choose to turn on the air conditioning, do not open it for a long time, and it is not possible to open the external circulation on the highway, and you can choose to open the internal circulation when the temperature is relatively low.

1.The calendar was unprecedentedly ventilated. When a car is exposed to sunlight, the temperature inside the car is high.

At this time, it doesn't have much impact to open the empty directly. The best way is to roll down the doors and windows on the side of the cab before getting into the car, and then open and close the door ten times in the passenger position to accelerate the air circulation inside and outside the car and reduce the temperature in the car. 2.

The rational use of the inner circulation air should replace the internal circulation. Turn on the external circulation every 30 minutes, clean the air in the car for five minutes, and then switch back to the internal circulation. Advocate the wind speed and upward direction, block the hot air outside the car, and form a closed empty room in the car, so that the air air can be quickly convected to achieve the effect of rapid cooling.

3.Check the cooling effect of the air conditioner. Refrigerants are the core of air conditioning cooling.

When the air conditioning system is turned on in summer, the first thing to see is whether the proportion of refrigerant made by the air conditioner is appropriate. Too much or too little will affect the refrigeration effect, and it can also be moderately throtted and oil-free. 4.

Turning off the null switch before parking not only protects the engine, but also saves fuel. 5.Don't let the wind blow in the direction of the wind.

The correct way is to choose to blow obliquely upward, and use the law of hot air rising and cold air falling to cool the air from the top to the bottom. At the same time, be careful not to place any decorations in front of the empty air outlet, which will affect the heat dissipation effect of the air conditioner. 6.

Some car owners drive at high speed and choose not to open the window to ventilate and cool the air, which is the wrong approach. In fact, 80% of the fuel consumption of the car is to resist the air resistance, and the ventilation resistance of the window is greater, so it is not fuel saving but fuel consumption. 7.

Air Adjustment Cleaning In the summer, before using the shut-off air switch, be sure to clean the shut-off air switch, because first of all, if the shut-off air switch is not used for a long time, a large number of bacteria will accumulate, which is harmful to the human respiratory tract. Secondly, the efficiency of the clean shut-off air switch will be improved, which will naturally reduce fuel consumption. Millions of car purchase subsidies.
