Is it better for a car to turn off the air conditioner or turn off the engine first?

Car-related air conditioning is better for the car, if it is to turn off the engine first and then turn off the air conditioner, it is meaningless, because only after the air conditioner is turned on, at this time, you go to turn off the air conditioner is your own subjective to turn off the air conditioner, after the fire is turned off, the car as a whole is turned off, the air conditioner is automatically turned off, that is forced to turn off, so if you take the initiative to force off, you still take the initiative to force the damage to the car is small.

I think turning off the air conditioner before parking will protect the air conditioning system. Because the air conditioner is still running, it suddenly goes out, which has a little bit of an impact. If you forget to turn off the air conditioner after turning off the engine, it will carry the pressure of the air conditioner when it starts the next day, and such a high load will hurt the engine and battery, and will also increase fuel consumption.

It is better to turn off the air conditioner first, because it is easier to get repaired, and if the engine is turned off first, it is easy to cause the air conditioner to break, which is very bad to get used to.

Turning off the air conditioner is better for the car, because turning off the air conditioner will save some fuel and will not make the performance of the car too bad.

It is better for the car to turn off the air conditioner first, if the engine is turned off first, the air conditioner will be forced to turn off automatically, which will have a bad impact on the car.

I think the car should turn off the air conditioner first, and then turn off the engine, which is better for the car, because if the engine is turned off directly, the air conditioner will be used for a much shorter time.

I think the car should turn off the air conditioner and then turn off the engine, which is better for the car, and when the vehicle is about to turn off, the AC switch of the air conditioner should be turned off ten minutes in advance.

Turn off the air conditioner first when the engine is turned off, and the air conditioner will automatically turn off after the engine is turned off, and the air conditioner will not be turned off first.

The air conditioner needs to be turned off before the car is turned off;

The reason is that the air conditioner relies on the car's battery to operate, if you don't turn off the air conditioner for a long time and turn off, the next time you start the car, it will not only damage the life of the battery, but also affect the efficiency of the engine, or it will have an impact on the air in the car and car navigation.

In short, whether it is daily life or driving, you must develop good habits, which brings great convenience to yourself!

Remembering to turn off the air conditioner after the engine is turned off is detrimental to the engine. This is because the next time the vehicle starts, the engine will start with the load of the air conditioner, and such a high load will damage the engine. Therefore, the air conditioner should be turned off and then turned off after each stop, and the air conditioner should also be turned on after two or three minutes of starting the vehicle and the engine has been lubricated.

It is recommended to manually turn off the refrigeration (with the AC logo on the button) but keep the air conditioner blower running for a period of time (i.e. do not turn off the air supply) a few minutes before each flameout. This will help the air conditioner evaporation box to evaporate the surface moisture as soon as possible when it rises to the ambient temperature, preventing its moist surface from becoming a breeding ground for bacteria, thereby preventing the odor in the car brought by the air conditioner evaporation tank. Here's why:

When the automobile air conditioner is actually working, the temperature of the evaporation box can be as low as nearly 0 degrees, far lower than the ambient temperature, and the water vapor in the air will condense on the surface of the evaporation box to form water droplets. These water droplets provide an environmental basis for the growth of fungi, when the air conditioner is working, due to the low temperature of the evaporation tank, the fungal breeding is not obvious, once the compressor stops running, the refrigerant stops circulating, the temperature of the evaporation box rises, and its surface becomes warm and humid, becoming the best hotbed for fungal growth.

Consciously turn off the compressor in advance before the flameout to keep the blower working, the air flows through the surface of the evaporation box under the drive of the blower, which will take away a lot of moisture, dry the surface of the evaporation box, change the humid environment on the surface of the evaporation box, and greatly slow down the appearance of the evaporation box odor.

Finally, the opening and closing of the air conditioning system is controlled by the air conditioning clutch, and turning off the engine without turning off the air conditioning compressor has no effect. However, the air conditioning blower is controlled by an ignition switch, and the current will increase the moment the vehicle starts. If the vehicle is already relatively old and the circuit system is defective, you need to pay attention to it.

Such a complex manual operation will damage the engine, I personally think it is impossible, I drove two new lanes to scrap, never turn off the air conditioner and then turn off, never found that there was a problem with the engine, I asked, such a theoretical design gods have not considered it for decades? Will the air conditioner be designed to be extended before restarting again after the engine is turned off? ......My current Buick LaCrosse ordinary version (06 model) has been driven for thirteen years, driven more than 300,000 kilometers, and very little maintenance, everything is beautiful, fuel consumption has hardly changed, the power is OK, and I don't feel hurt anything, I have changed two shock absorbers, I have changed the battery four times, I have replaced an ABS sensor once, I have changed the lifting glass, the engine and the gearbox air conditioning generator have not been replaced, not to mention that the air conditioner has not been damaged!

This is a personal opinion......

The air conditioner needs to be turned off before the car is turned off, because the air conditioner relies on the car's battery to operate, if it is not related for a long time, the air conditioner will turn off, and the life of the battery will be damaged when the car is started next time. It will also affect the efficiency of the engine.

When the car is parked, it is best to turn the air conditioner on before turning it off. If you turn off the engine and then turn off the air conditioner, it will increase the burden on the engine.

1. Turning off the engine first and then turning off the air conditioner will cause serious injury to the car.

If the driver chooses to turn off the engine first and then turn off the air conditioner, then the next time the car starts, the engine will start again with the load of the air conditioner, which will hurt the car very much. Although it is okay once or twice, starting the engine under high load for a long time will shorten the life of the engine and increase the wear rate of the engine. Therefore, car owners should try to remember to turn off the air conditioner before turning it off.

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

The best way to do the air conditioner in the car is to turn off the air conditioner a few minutes before arriving at the destination, so that the temperature inside the car will slowly drop to the same as the outside of the car, and then turn on the natural air, which will make the temperature in the air conditioning duct rise and slowly eliminate the temperature difference between the air conditioner and the outside world. Natural winds also keep the air-conditioning system relatively dry, making it cleaner and more hygienic. In addition, you can turn on the air conditioner at the same time as starting the engine next time, but it is not recommended to turn on the refrigeration system of the air conditioner immediately, it is best to wait for 3 or 5 minutes before turning on the refrigeration system of the air conditioner, so that the wear and tear on the engine will be less.

Of course, if the weather is not particularly hot, it is recommended to open the window for ventilation for a few minutes before turning on the air conditioning and refrigeration system.

3. How to use air conditioning.

The air conditioning in the car not only has a cooling system but also a heating system, which can provide a better driving environment for the owner in winter and summer. However, there are many tricks in the use of air conditioners, such as turning on the air conditioning system in summer, you should first connect the internal circulation, and then open the external circulation after a while to play a role in ventilation. In addition, in the case of long-term air conditioning, it is more fuel-efficient if it is not a small air volume, and it is best to turn it on to the maximum air volume every once in a while, so that the air conditioner can blow out the dust inside, thereby improving the service life.

The car should be turned off by turning off the air conditioner and then turning off the engine; This is because if the engine is turned off first, it will cause damage to the planning machine, and the next time the vehicle is activated, the planning time will be activated with the load of the air conditioner, which will endanger the planning machine.

The car should turn off the air conditioner first and then turn off the engine; Because if the ignition is turned off first, it will cause damage to the engine, and the next time the vehicle starts, the engine will start with the load of the air conditioner, which will damage the engine.

Turn off the air conditioner before turning it off, because if you turn off the engine first, it will cause damage to the control system of the air conditioner, and it is easy for a large amount of dust to accumulate in the air conditioner.

The correct thing to do is to turn off the air conditioner and then turn it off, as this will keep the car in better condition.

The car should turn off the null switch a few minutes before stopping, otherwise it will be harmful to the engine because the next time the car starts, the engine will start with the load of the null switch.

Turning off the engine first and then turning off the air is harmful to the engine, because the next time the vehicle starts, the engine will start with an empty load, and such a high load can easily damage the engine.

Solution: Turn off the air cooling air a few minutes before the next use, use the natural wind to eliminate the temperature difference between the inside and outside of the air conditioning air duct, make the temperature in the air conditioning air duct rise, eliminate the temperature difference with the outside world, keep the air conditioning system relatively dry, and avoid the spread of mold. Also, you should turn on the empty after the vehicle has been started for two or three minutes and the engine has lubricated.

In the hot summer, many car owners are accustomed to turning on the empty circulation as soon as they get in the car, thinking that this will make the temperature in the car drop faster. This is not right, because the temperature inside the car is higher than the outside, so it is ineffective. In the internal circulation mode, the air inside the car cannot be exchanged with the air circulation outside.

Over time, the air in the car will become turbid, and the oxygen content will gradually decrease, which is harmful to the health of drivers and passengers.

Solution: When the empty opening Bina Pai off is just opened, it is recommended that the owner first open the inner circulation for a while, and then switch to the outer circulation to start ventilation.

If the car air is not cleaned for a long time, all kinds of dust and dirt will accumulate on the dust filter, and through the air duct, a large number of bacteria, mold, and mites will breed on the empty evaporation box. The air conditioning system of a car is full of harmful bacteria such as germs, mold, etc. These harmful bacteria pollute the air of the whole vehicle with empty air, which may cause symptoms such as headache, fever, dermatitis and other allergic reactions, which seriously endanger human health.

Solution: It is recommended to clean the air 2-3 times a year. Motorists can make their own cleaning plans according to their own usage to ensure that the indoor air is fresh and healthy.

Generally, the air filter element is cleaned every 5,000 kilometers or 3 months, and the air filter element is replaced every 20,000 kilometers or 12 months. In addition, the condensate should be cleaned regularly.

Many car owners mistakenly think that it will consume more fuel when turning to the maximum gear, so they will try to reduce the air volume. In reality, this is not the case. If the air volume is mainly small for a long time, it will not only reduce fuel consumption, but also make it difficult to blow out the dirt in the air conditioning, which can easily lead to mildew and harm people's respiratory system.

Solution: Every once in a while, you need to turn the idling to the maximum gear, which can effectively prevent dust accumulation in about 10 minutes.

Millions of car purchase subsidies.

Therefore, the normal operation of the car is to turn off the air conditioner first, and at the same time let the air supply system work for 1-2 minutes, and then turn off the engine is the most scientific operation. So let's talk about the impact of not turning off the air conditioner before the vehicle is turned off?

If the air conditioner is not turned off before the ignition is turned off for a long time, it will have an impact on our air conditioning system and engine.

The impact of not turning off the air conditioner before turning off the air conditioner on the car air conditioning system: If the air conditioner is turned off, the air conditioner evaporator and ventilation duct will form condensate on the surface due to the temperature difference, which will easily lead to mold in the air conditioning filter and air supply pipe, resulting in peculiar smell. Therefore, it is recommended to turn off the air conditioner before the engine is turned off, and keep the air supply system working for 1-2 minutes to keep the surface of the evaporator and the ventilation duct dry.

Just like our home air conditioner, if we turn off the air conditioner, the fan will continue to work for a while.

The effect on the engine after the engine is restarted without turning off the air conditioner before turning off the engine:

If the air conditioner is not turned off before one or two times the engine is turned off, it will not have much impact on the engine, because the current vehicle design will not start the compressor if the air conditioning switch is turned on or not at the moment of engine starting, and it will not increase the load on the engine. However, if the air conditioner is not turned off before turning off the engine for a long time, it will be harmful to the engine. If this is done for a long time, the engine will be overpowered by excessive current at the moment of start-up, which will easily burn out the starting motor of the air conditioner compressor.

In addition, starting with the air conditioner, the fuel consumption will increase when idling for a long time, and the carbon deposition of the engine will also increase. Finally, it will affect engine performance.

Therefore, we should develop the habit of turning off the air conditioner before turning off the engine and then turning it off, which is good for the air conditioning system and engine of our vehicle.

Let's talk about my personal usage habits first.

Generally, I will first turn on the circuit, let the driving computer self-test and then start the vehicle, the vehicle preheats up and idles smoothly ** and then turn on the air conditioner, then turn on the fan, turn off the air conditioner and then turn off the fan before turning off the engine, as for why I do this, I personally think that the engine that has just started is still in a cold state, and it takes some load to drive the air conditioner, just like a person who just woke up and grabbed the dumbbells to practice biceps, I think few people feel comfortable, then if the start is connected to the air conditioner, some people will feel that the engine is damaged, I think the car The engine is not so weak, and so far I have not heard of anyone who started it like this and caused the engine to fail. Final summary: it depends on personal habits.

Try to turn off the air conditioner first, of course, the better cars don't need to turn off automatically.

Only do I have such a bad habit, the air conditioner has not been turned off (low-end cars), it is turned on when it is started, and it is turned on when the engine is turned off.
