Do you know how to turn on the car air conditioner to save fuel?

First of all, remember the rule of 60 80, that is, when the speed exceeds 80 kilometers per hour, the window will increase the resistance, and the fuel consumption at this time is much greater than the fuel consumption of the air conditioner, so when the speed is less than 60 kilometers per hour, it is possible to directly open the window to ventilate, but when the speed exceeds 80 kilometers per hour, it is relatively less fuel-efficient to choose to turn on the air conditioner at this time.

Secondly, the temperature of the air conditioner is not as low as possible, if the air conditioner is directly set to an ultra-low temperature, the air conditioning pump will not stop when it is running, which will increase the load of the car, and the purpose of fuel saving is naturally not achieved, under normal circumstances, the temperature in the car is lower than the outside of the car 5 is a comfortable and fuel-saving temperature.

Then, I want to tell you that there is also a skill in turning on and off the air conditioner, and after getting on the car, you should first open all the windows to let the cabin temperature drop naturally, and then turn on the air conditioner, so that the pressure on the engine when it starts to run will be reduced a lot. I hope you can use these tips to turn on the air conditioner, save fuel and comfort without delay.

How to turn on the car air conditioner is the most fuel-efficient? Many people are accustomed to turning on the air conditioner as soon as they enter the car, but the temperature inside the car is higher than the temperature outside the car, so this is not effective. The correct approach is that when you first enter the car, you should first open the window for ventilation, exhaust the hot gas, and then turn on the air conditioner after the temperature in the cabin drops, which will not add too much burden to the engine, which saves fuel and protects the engine.

The car air conditioner is the most fuel-efficient with internal circulation and small air volume, and the car air conditioner should be ventilated before opening and the unnecessary air outlet should be closed, which is a small skill that people should master.

Cars need gasoline to provide energy, whether it is driving forward, or turning on the air conditioner to listen to the ** need to consume fuel, so fuel saving is a matter of great concern, many people want to know how to turn on the car air conditioner is the most fuel-efficient. It is more fuel-efficient in the state of open internal circulation, and the smaller amount of light can also save fuel, and it can also make the interior environment more comfortable.

1. Ventilate before driving

In the hot summer, people's cars are mostly parked in the garage or outdoors, the temperature in the car is particularly high, when driving directly open the door into the car to turn on the air conditioner to the maximum, then it will cost fuel, so before driving, it is best to open the doors and windows first, let the air circulation in the car, let the temperature in the car drop down some, and then start the car, turn on the air conditioner will save fuel, and will let the temperature in the car drop to the range that people expect as soon as possible.

2. Reduce the air volume

The car air conditioner is more fuel-efficient after reducing the air volume, but it is also necessary to ensure that the car is cool, so you have to find a suitable degree, which can not only make the environment in the car comfortable, but also save fuel, you must repeatedly adjust it to test what kind of air volume is the most suitable. People reduce the air outlet of the air conditioner, and after reducing the air volume, it will also reduce the energy consumption of the evaporation box, which will also play a certain role in fuel saving.

3. Open the internal circulation

In the normal driving process of the car, open the internal circulation to save fuel, because when the internal circulation is opened, the air conditioning system will always use the air in the car to circulate the refrigerant liquid, the lower the temperature in the car, the lower the power of refrigeration, if the external circulation is opened, it will let the car inhale the high temperature gas outside the car, which will affect the normal operation of the air conditioning system, and will also increase their refrigeration power, which will increase their fuel consumption.

Fourth, close unnecessary air outlets

When the car turns on the air conditioner, the more air outlets are opened, the greater the energy needs to be consumed, so when the air conditioner is turned on in the process of driving, the unnecessary air outlets can be closed, especially when a person drives or only the front seat is occupied, the rear air outlets should be closed, so that the energy consumption of the car can play a good role in fuel saving.

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.

Turn the air conditioner into the style of internal circulation, which will make the car air conditioner the most fuel-efficient; It is best to turn off all the air outlets that the car does not need, and only open the air outlets that the car needs, and adjust them into internal circulation.

Be sure to ventilate first, then reduce the indoor temperature, adjust the air volume, and don't turn on the air conditioner with a large air volume at the beginning. This is more fuel-efficient. It is better to turn on the inner loop.

After just getting into the car, you first need to open the external circulation to exhaust the hot air, and then open the internal circulation, and then open the internal circulation to roll up the window, do not open the window, usually pay more attention to check whether there is any foreign object in the air conditioning outlet, and adjust the wind speed and wind direction reasonably.

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.
