In the hot summer, how to turn on the car air conditioner to be fuel efficient and cool?

The hot summer has appeared in front of us, the scorching sun is like a fire, and it is almost a handful of cumin powder to go out. After experiencing a wave of heat outside, the car owners who go out every day are eager to return to the car and turn on the air conditioner to enjoy the coolness. However, after enjoying the coolness, I slowly came to my senses, my God, how did the pointer on the fuel gauge drop so quickly, I couldn't help but feel distressed.

Many car owners are thinking about how to turn on the air conditioner in the car in summer to be cool and fuel-efficient? Listen to me.

1. Open the door for ventilation before getting into the car.

The weather is getting hotter and hotter, and many car owners turn on the air conditioner as soon as they get in the car, but with the continuous increase in oil prices, many car owners must be hesitant between reducing fuel consumption and cooling and comfort for a long time. In fact, there is a correct way to cool down, which can not only allow car owners to enjoy coolness, but also save fuel costs. After the summer vehicle is placed outdoors for a period of time, the temperature in the car will be very high, and the car will be extremely stuffy, at this time directly turn on the air conditioner, the effect is not very good, the correct way is to open the four doors before getting on the car, so that the air forms convection inside the car body, convection can quickly take away the heat in the car, so that the temperature in the car will soon drop, and then we turn on the air conditioner, we will find that the refrigeration effect of the air conditioner is far better than the refrigeration effect of not opening the door for ventilation before.

2. Close the windows when the air conditioner is in use.

Some car owners are accustomed to turning on the air conditioner in the vehicle, leaving some gaps on the window, thinking that the air conditioning refrigeration effect is faster, in fact, this is wrong, because the window is not closed, it is bound to bring the external hot air into the car, thereby affecting the refrigeration effect of the air conditioner, and eventually will lead to a significant increase in the fuel consumption of the vehicle.

3. Regularly maintain the air conditioner.

The quality of the refrigeration effect of the air conditioning in the car, in addition to the temperature in the car, is largely related to the quality of the air conditioning itself.

It is also necessary to remind everyone here that when the car is in an idle state for a long time, try not to turn on the air conditioner to cool off, because in the state of idling, gasoline will produce carbon monoxide due to insufficient combustion, and in this closed environment in the car, the accumulated carbon monoxide will cause poisoning to the people in the car after reaching the concentration, and the consequences are very serious. If you have to turn on the air conditioner, leave a gap in the window to allow fresh air to circulate.

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 there are any foreign objects in the vents, etc., you can turn on the ventilation mode first, and let the air conditioner blow the dirt 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.

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.

When the air conditioner is turned on and ready to stop, try to turn off the air conditioner 5-10 minutes in advance, don't underestimate these few minutes, you can save a lot of fuel. In this way, the temperature in the car will not be too high, and secondly, you can get off the car and adapt to the temperature as soon as possible.

Try to park in the shade as much as possible.

When parking in summer, try to find a shady place under the shade of trees, under the wall, etc., so that the vehicle is not exposed to the sun and will not be very hot. Or it's not bad to cover the car with a sunshade. In this way, if you start the air conditioner when driving, the cooling will be very fast, and it will save a lot of fuel compared to the steamer car.

Summer is here, and it must be the hardest time of the year for all car owners and friends. When driving in hot weather, air conditioning is the best companion. It really can't be possible without it.

So, how can air conditioners save fuel in summer? In summer, especially in outdoor surface parking lots, when we open the car door, we usually feel a heat wave coming towards us. That's because in this relatively closed environment in the car, there is no air circulation, which leads to heat accumulation.

If you immediately enter the car and turn on the air conditioner, it will not only waste fuel, but also the cooling effect will not be good. In fact, you can lower the three windows first, leaving one closed, so that the air will collect in the rear seat to form a high-pressure area after entering the car, forcing the hot air in the car to exhaust from the rear side window. Of course, you can also open the door and push and pull hard a few times (like a fan), or quickly pull the hot air out of the car.

After the temperature in the car cools down, start the engine and turn on the air conditioner, which is both fuel-efficient and good! Open the cycle first, and then change the inner cycle. In summer, when the car is parked outside, some harmful gases are produced inside the car.

In this case, you can first adjust the air conditioner to the external circulation, then close the window and open the internal circulation refrigeration. When we turn on the internal circulation, the air conditioning fan directly sucks the air in the car through the evaporation box to cool down, and then sends it out from the air outlet. As the temperature inside the car drops, the temperature of the air drawn in by the fan will slowly decrease.

Under certain circumstances, the temperature of the cooling air sent by the air outlet of the refrigeration system will be lower, resulting in positive feedback, and the temperature in the car will quickly decrease to the set value. At this time, the air conditioning compressor works intermittently (or the power is reduced), the load becomes smaller, and some fuel consumption is saved. It is more appropriate to open 25 degrees during internal circulation.

I believe that many car owners tend to set the temperature of the air conditioner in the car to the lowest temperature in order to speed up the cooling effect, which is actually wrong. Because fuel consumption is greatly increased, the air conditioning compressor and blower equipment will always be running, and the low temperature in the car will also have a detrimental effect on health. Under normal circumstances, when the air conditioner is turned on, it can be set to about 22 degrees Celsius.

After the temperature drops, it is more reasonable to turn on the internal circulation and set the air conditioner at around 25 degrees Celsius. Theoretically, the principle of air convection is that hot air goes up and cold air goes down. Therefore, the air conditioning outlet should be blown upwards so that the temperature in the car will decrease faster as the cold air drops.

When the temperature inside the car reaches the set point, it can also reduce some fuel consumption. The above are some tips for turning on an air conditioner in summer to save fuel. I hope it will be helpful to riders.

It is best to choose to blow upwards, so that it will feel very practical, and the car will also be fully circulated, and you can also get a good range of cooling maximum efficiency. Withered envy.

Before turning on the air conditioner, be sure to open all the windows to let the air circulate, and then turn on the air conditioner to open the inner barrier to circulate, so that you can achieve the purpose of returning to the forest to cool down, and then adjust the lights to the air outlet and adjust to the upper position.

When turning on the air conditioner, turn on the power to the maximum, then open the window to exhaust the hot air, and finally close the window, which is efficient and cool.

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.

First of all, we must grasp the timing of turning on the air conditioner, first open all the windows, and then turn on the air outlet volume of the air conditioner, adjust it to the external circulation to drive out the hot air in the car, and then change it to internal circulation after getting into the car, so that the temperature in the car will drop rapidly. Secondly, it is necessary to check whether there is any debris at the air outlet of the air conditioner, and finally to use the air conditioner reasonably.

1. To grasp the timing of turning on the air conditioner, when you first enter the car, you should first open the window for ventilation, and turn on the external circulation to exhaust the hot air. Wait for the temperature in the compartment to drop, and then switch to the inner circulation. This does not add any burden to the engine at idle, saving fuel and protecting the engine.

Before you reach your destination, turn off the air conditioner early, then turn on the outdoor circulation, using the wind and the residual temperature of the air conditioner to keep the cabin cool.

2. Wind direction adjustment, the adjustment of wind direction and temperature of the air conditioner will also affect fuel consumption. When turning on the air conditioner, the wind direction should be upward, because the air conditioner is sinking downward, which can be neutralized with the rising heat, and the cooling speed is also the fastest.

3. Always check the air outlet of the air conditioner, and ensure that the air outlet of the air conditioner is smooth and free of debris, so as to prevent it from being blocked by foreign objects and affecting the wind out of the stove, which will make people adjust the air conditioning gear in advance and increase fuel consumption.

4. Urban driving can be switched on and off alternately, the low-speed start and stop of urban driving is the most fuel-intensive, the engine heat dissipation is not good, and a lot of power support is required when starting and starting the air conditioner, so the fuel consumption is especially large. At this time, one can consider turning off the air conditioner window; Second, you can also use the method of switching the air conditioner on and off alternately to escape the heat.

Without considering whether it is harmful to the body, the air conditioner is turned on in the whole cycle, so that the temperature of the cab drops quickly, and it can be turned off for a while when it is cold. Then it is to drive at night or on a cloudy day to avoid sunlight, and the time for using the air conditioner will be reduced, which will naturally save fuel and lose dates. You can also do someone else's car and let him dismantle the air conditioner, which is the most fuel-efficient.

Usually the vehicle air conditioning system should pay attention to maintenance, and pay attention to the key points, the vehicle air conditioning filter must be replaced before the summer, the filtration effect will be better, the air conditioning radiator can be cleaned by the way every time the car is washed, to keep the air conditioning radiator heat dissipation effect normal, is one of the key contents of the air conditioning refrigeration effect, the switch of the vehicle air conditioning compressor coupler, even in the cold winter, should be in the state of not turning off the engine after parking, turn on the air conditioning a c switch and run for a few minutes, is to carry the necessary or necessary maintenance measures, It is better to operate more than twice throughout the winter, so as to avoid the trouble of repairing the air conditioning system in summer, and save worry and money as well as fuel money.
