Does the car turn on the air conditioner according to the size of the air conditioner, and how much

Generally speaking, as long as the air conditioning compressor starts to work, the size of the wind has nothing to do with fuel consumption, which can be ignored, the power of the engine directly used by the compressor is large, and the wind dispersion of the fan is the same as the condenser, which increases the load of the generator but is very small. The general car temperature setting is the bottom 18 degrees (some cars do not have a temperature function), but to 18 will be very cold, the car's air conditioning will not be able to drop to that temperature, the basic air conditioning system is still working, the window will be resisted to increase fuel consumption, is very little, open the sunroof is better.

1. If the air volume increases, the fuel consumption will definitely increase.

Simple identification method: turn on the air conditioner in the first and second gears respectively, record the start and stop time of the electronic fan of the air conditioner, and it can be found that when the air volume is large, the running time of the electronic fan is longer; Similarly, high air volume will quickly reduce the temperature in the car, according to the principle of energy replacement, the cooling capacity is large, the work will be more, every more than 1 degree decreased, will make more than 1 degree equivalent of work, fuel consumption will also increase; However, the actual increase in fuel consumption does not increase much (compared to turning on the air conditioner and not turning on the air conditioner).

2. Which is more waste oil between turning on the air conditioner at high speed or opening the window, no one has deliberately measured it.

At low speed or idle, the engine needs to increase the speed to make the air conditioner run normally, and the relative fuel consumption is high; At high speed, the engine has high speed and high power output, which drives the air conditioner and has much lower fuel consumption. The noise of high-speed window opening is high, and the temperature is not low in hot weather, so it is more cost-effective to turn on the air conditioner. If you have a skylight, you can open the skylight, if you don't, often open the external circulation, replace the air, and keep your mind clear.

The size of the air conditioner in the car will definitely affect the fuel consumption. Driving in summer consumes more fuel, because in summer we will turn on the air conditioner, and after turning on the air conditioner, the fuel consumption per 100 kilometers will be about two liters higher than when the air conditioning is not turned on. The reason why the fuel consumption of the vehicle will increase significantly after the air conditioning is turned on, the main reason is that the compressor is working, because the power of the compressor is relatively large, so the load of the engine is relatively large, and the natural fuel consumption will go up.

If you talk about a small displacement car, you will even feel a significant drop in power.

The lower the temperature of the air conditioner, the greater the fuel consumption.

The correlation between air conditioning temperature and fuel consumption is more obvious. If it is a variable displacement compressor, when the temperature is lowered, the compressor must maintain a high displacement state for a long time, and the fuel consumption will be large; When the temperature is turned up, the compressor can reduce the displacement, the load on the engine will also be reduced, and the fuel consumption will be reduced.

If it is a constant displacement compressor, when it first starts working, regardless of the temperature of the air conditioner, the fixed displacement compressor is working at full load.

1. The wind speed of the air conditioner has nothing to do with fuel consumption, because the exhaust fan of the air conditioner uses the electricity of the generator, not anything else! The power consumed by the generator is basically a certain amount, and whether you use it or not consumes this bit of power, that is, no matter what, the electricity of the generator is enough, not enough for you to use or not to use! It doesn't matter if you use more or less!

2. The temperature of the air conditioning outlet is related to the fuel consumption, which is related to the working intensity of the air conditioning compressor, and the working intensity of the compressor directly consumes the power of the engine! However, the overall impact is not large, and the increase in fuel consumption caused by traffic jams or frequent starts and stops is negligible!

There is no correlation between the air conditioning gear and fuel consumption, the bigger the gear, but the greater the speed of your car fan, which has nothing to do with fuel consumption; The lower the refrigeration temperature of the car air conditioner, the more fuel is consumed, so it is recommended to adjust the car air conditioner to about 26 degrees on the best, and the car without temperature display should try not to hit the refrigeration to the minimum.

The bigger the air conditioner is, the more fuel will be consumed, because the operation of the air conditioner requires the compressor to work for refrigeration, so if you want to save fuel, turn on the air conditioner less!

Yes, the higher the gear, the higher the fuel consumption.

Yes, if you want to save fuel, turn on the air conditioner less!

The car air conditioner is turned on and the fuel consumption is the same.

The air volume of the car air conditioner has nothing to do with the fuel consumption, the car air conditioner mainly relies on the Luqi compressor to work, the compressor compresses the gaseous freon into a gaseous freon with high temperature and high pressure, and then sends it to the condenser to dissipate the heat and becomes a liquid freon at room temperature and high pressure.

The air volume will only affect the running speed of the motor, consume more battery power, and adjust the wind speed will not affect the control of the compressor, so only adjusting the wind speed without adjusting the temperature of the air conditioner will not affect the fuel consumption, and the fuel consumption generated is negligible.

No matter what compressor, as long as the temperature is low, the fuel consumption will inevitably be large. The air volume will be large, but it is not too big, and the temperature has the greatest impact on fuel consumption. Therefore, you don't need to adjust the temperature too low to turn on the air conditioner, take the feeling of not being hot as the standard, adjust it at any time, and don't adjust it and never move again.

Precautions when using a car air conditioner:

1. Although the car air conditioner will consume a certain amount of electricity, it will also cause the air conditioner to age if it is not used for a long time, so the air conditioner should be started frequently.

2. When adjusting the air speed of the air conditioner, it must be avoided to control it at the lowest level for a long time.

3. Neither can the air conditioner not be used, nor can the air conditioner be turned on all the time, and it can be turned off appropriately for a while when the suitable temperature is reached.

4. Before the car is opened, the car should be ventilated, especially if you want to respect the code for refrigeration, you should open the external circulation to exhaust the hot gas.

5. When the vehicle is ready to turn off, if the air conditioner is turned on, be sure to turn off the air conditioner before turning off the engine.

Is the fuel consumption of car air conditioner the same for different gears? The fuel consumption of the first gear and the fourth gear or other gears of the automobile air conditioner is basically not much different and can be ignored. Because the air volume level of the air conditioner refers to the air volume of the blower, that is, the speed of the blower is different.

Because of the difference in the speed of the blower, the difference in engine load is very small, so the fuel consumption can be basically ignored. Nowadays, many household vehicles use automatic air conditioning, and the compressor is a variable frequency compressor. When the air conditioning system is working, the amount of fuel consumption is related to the load on the engine, but the load on the engine when the air conditioning is turned on depends on the desired temperature of the air conditioner adjusted by the driver.

For example, when the indoor temperature adjusted by the driver is 18 degrees Celsius, when the air conditioning system is working, it will adjust the cooling power of the air conditioning system and the air volume of the blower according to the value of the temperature sensor in the car, so that the car can quickly reach the desired temperature.

When the air conditioner automatic mode is selected, the working state of the air conditioning system will be automatically adjusted when the desired temperature is reached in the room. If you are not using the automatic mode, you will continue to be in the same power cooling mode.

When the driver's desired temperature is different, the air conditioning mode is different, and the engine load caused by the air attack and shouting system is not the same, the engine fuel consumption will be significantly different.

Millions of car purchase subsidies.

In fact, the fuel consumption of the car air conditioner refers to the cooling and heating of the car air conditioner, which will not affect the fuel consumption of the car and has nothing to do with the gear of the air conditioner. Automobile air conditioning refrigeration requires the work of air conditioning pumps. The power of the air conditioning pump comes from the engine, so the work of the air conditioning pump will lose part of the power of the engine, so the air conditioning and cooling of the car will affect the fuel consumption of the vehicle.

It's a fact. Car air conditioning heating uses the heat of the engine and depends on the flow of coolant, such as the warm air box in the evaporation tank, which is blown into the cabin by a blower from the air conditioning line. If the air conditioning pump is not operated, there is no loss of power in the engine and no impact on the fuel consumption of the vehicle.

Is the fuel consumption the same when the car air conditioner is in the highest and lowest gears? However, when the temperature is adjusted, the fuel consumption will vary accordingly. The lower the temperature, the worse the fuel consumption.

Therefore, for the sake of your wallet, from an environmental point of view, the air conditioning temperature should not be adjusted too low when traveling.

In addition, it is advisable to buy an air conditioner with variable displacement when buying a car. The power of the constant frequency air conditioner has remained the same, but in most cases, it can still make people feel comfortable after turning on it for a period of time, but the air conditioning in the car will still maintain high consumption, even if the temperature in the car is too low, the natural air temperature in the car automatic air conditioning is invested, and the purpose of reducing fuel consumption cannot be achieved. Not all cars need gasoline!

The key depends on the compressor used in the car. If your car is a variable displacement compressor, you don't need to save fuel to regulate the temperature and wind speed, because for a car with a fixed displacement air conditioning pump, as long as the air conditioning is turned on, the fuel consumption is almost the rated value, which has nothing to do with temperature and air volume. Conversely, for variable compressors, fuel consumption is temperature-dependent.

If you don't know what type of compressor your car is, it's usually written in a manual and marked on the compressor.

How does a car air conditioner affect fuel consumption? There are two main systems of automotive air conditioners: air outlets and refrigeration systems.

The main factor affecting the fuel consumption of automobiles is refrigeration, and the air volume has little to do with fuel consumption. The air volume only affects the speed at which the motor runs, consuming more battery power and having negligible fuel consumption. In summer, the temperature in the car is very high.

Turning on the air conditioner as soon as you get into the car not only does not cool well, but also increases the engine pressure during initial operation. After opening the door, it is best to open all the windows of the car and wait for the temperature in the car to drop significantly before turning on the air conditioning. When you arrive at your destination, you think of turning off the engine and then turning off the air conditioner, which is also very harmful to the engine.

You should make it a habit to turn off all the air conditioning, stereos, and lights in your car before turning off the engine.

The fuel consumption in the neutral gear is the lowest, because the air conditioner will drive the engine to run after it is turned on, but the gear is kept in the base branch after the neutral gear, the running speed is relatively slow, and the oil content consumed is also relatively low.

Try to choose the position of the third gear when you are in the most fuel-efficient position, because there will be no lag at this time, and the search speed is relatively fast, and the effect will be better.

The effect is the same, the fuel consumption of the high and low gears is basically the same, and it is also related to the speed.

In fact, a generator and an electric motor are the same. The housing is a stator coil and the shaft is a rotor coil. If you want it to generate electricity, first energize the rotor coil to create a magnetic field, then the rotor rotates to create a rotating magnetic field, and then the rotating magnetic field cuts the stator coil on the housing to generate an electric current.

Therefore, power generation can be controlled by adjusting the current of the rotor coil. The current to the stator coil is called the excitation current. The larger the excitation current, the stronger the magnetic field, the greater the power generation, and the greater the rotational resistance of the generator.

So, theoretically, when you adjust the airflow to a higher gear, you increase the amount of power generated by the generator, which will inevitably lead to an increase in engine drag and fuel consumption.

The air speed regulates the air volume of the air outlet. **There is a centrifugal fan under the console that provides air volume to the air outlet. The faster the wind speed, the faster the fan spins.

Of course, the more power is consumed. Is it using electricity? It can't be a battery, because during the operation of the car, there are too many electrical appliances that are suffocating with electricity, and one battery simply cannot meet it.

As a result, fans use electricity from generators, while car generators can regulate the amount of electricity generated. If you use more Zizaga, it will generate more electricity, and if you use less, it will produce less electricity. Therefore, the higher the wind speed gear, the more power the generator can generate.

We all know that the fuel consumption when the air conditioner is turned on is because the engine has to drag the air conditioner compressor, but you know, the compressor is not always running. The liquid high-pressure refrigerant delivered by the compressor evaporates in the evaporation chamber and absorbs a large amount of heat, creating a low temperature in the evaporation chamber. As the fan-driven air passes through the evaporation tank, the air is cooled and then delivered to the cab.

But the evaporation tank has a bad temper, that is, it is afraid of low temperatures. When the temperature of the evaporator is too low, it is prone to frost. Once frost has formed, the evaporator will be completely clogged and the air conditioner will be windless.

Therefore, the air conditioning system will specifically monitor the temperature of the evaporation tank. If it is close to frost temperatures, the compressor will be turned off. When the air volume is small, the evaporation tank is more likely to approach the frost temperature, and the compressor has a longer downtime.

When the air volume is large, the refrigeration capacity consumption of the evaporation tank is large, and it is difficult to reach the frost temperature. At this point, the compressor may run all the time and the fuel consumption must be higher.

The fuel consumption of neutral gear is the lowest, because after the neutral gear is opened, the running speed of the car will be very slow, and the fuel consumption is very low after the empty slag.

Both the top and bottom gears are very fuel-efficient, because the cars in both gears are driving at a constant speed, and the consumption is not very large.

The middle gear consumes the lowest fuel, and the highest gear and the lowest point are more fuel-guzzling.

It must have a very strong impact on fuel consumption, and the different gears of the air conditioner will also lead to different situations in fuel consumption. If the air conditioner is turned on relatively large, the fuel consumption of the car must be more.
