Do you need to turn on AC when the car heater is on? What does AC do?

With the continuous improvement of people's living standards, the requirements for cars have also increased a lot, and if there is no air conditioning in the car when driving out, the experience is also uncomfortable. However, there are many car owners who do not know much about the car air conditioner, such as whether to turn on the AC button when the car heaters the heater? After reading the car owner:

Posture up. If you don't understand, learn it.

AC key is the English air conditioning, that is, air conditioning adjustment, generally used in the summer for more time, its main role is to open the compressor refrigeration, if you do not need refrigeration, there is no need to press the AC key. In winter, the main reason for turning on the air conditioner is to need hot air, which will increase the temperature in the car. At this time, there is no need to use a compressor, only the heat generated by the engine operation needs to be brought into the air conditioning system, and then into the car, so that the temperature in the car can be raised.

Therefore, you don't need to press the AC button to turn on the heater, and many car owners are confused.

Many car owners are worried that turning on the air conditioner will increase the fuel consumption of the vehicle, so many times they would rather freeze their hands and feet in the car than turn on the air conditioner in the car. When you need to know here, turning on the heater in winter is to bring the heat of the engine into the air conditioning system, and this process will not increase the fuel consumption of the car, so you can use it with confidence. It is precisely because the heat of the heater is generated by the operation of the engine, so at the beginning of the car start, that is, when the engine temperature has not risen, do not turn on the heater, even if it is on, there will be no hot air out, and it will have to be driven for ten minutes.

Many car owners said: After reading the rising posture.

However, it is still necessary to remind everyone that the time to turn on the heater in winter should not be too long, and the window should be opened appropriately for ventilation, because the heat generated by the engine operation is blown into the car through the hot air, which contains some harmful gases, which will cause some harm to health. Moreover, if the heater is turned on for a long time, it is easy to produce fog on the window glass, resulting in a blurred driving vision, so you can turn on the "one-key defogging" function on the car to remove the fog on the window.

No. AC is the button that controls the cold air of the air conditioner, which is used for cooling in summer.

No, the AC is to turn on the air conditioning compressor, only when it is cooling, the heating is blown by the engine, so there is no need to turn on the AC.

No, the AC is the compressor switch of the air conditioner, and it can be turned on again when the cold air is used in summer.

When the car turns on the heater, should I turn on the AC button? After listening to the insider's analysis, I finally understood.

The AC is not needed to turn on the AC when the car air conditioner turns on the heater, the AC starts the air conditioning compressor, and the AC is not needed to turn on the heater, if the heater is turned on and the AC is turned on, the fuel consumption of the vehicle will rise.

Although it does not cost fuel to turn on the heater, do not turn on the heater immediately when the engine has just started, because the temperature of the water tank is too low at this time, which will increase the load on the engine, and will also delay the time when the water temperature rises, not only will not produce the heater, but also will lead to an increase in fuel consumption.

Generally speaking, when using car air conditioning for refrigeration in summer, if you need to use car air conditioning to cool down, you need to turn on the AC key on the panel in order to start the compressor of the car air conditioner, so that the car air conditioner can be cooled down.

In winter, when the car air conditioner is used for heating, the heat emitted by the air conditioner is not provided by the air conditioning compressor, but only uses the heat energy of the engine, so as to meet the purpose of winter heating.

In winter, if you use car air conditioning for heating, the owner must be able to do the work of heating the car, and do not turn on the air conditioning and heating system in the process of heating the car, let alone turn on the AC button, when the car completes the hot car work, the temperature of the water tank has risen, and then turn on the air conditioning and heating system.

The AC key of the car is the switch that controls the compressor, and the heater mainly uses the heat circulation inside the car to maintain the temperature in the car, in this process the compressor does not work, only need to adjust the air volume, and turning on the AC key may cause a waste of fuel consumption. Attached: Precautions for the use of warm air in winter:

1. Don't use the heater immediately when the cold car starts: when the cold car starts, the temperature in the water tank is relatively low, if you turn on the heater, not only can not increase the temperature in the car, but also "".

How car heaters work:

1.When the coolant temperature is high, it flows through the heat exchanger in the heating system, and the blower exchanges the air with the engine coolant, and finally the heated air is sent into the car through the air outlets. To put it simply, the heat of the engine coolant does not need to be used in vain, and the car heater is heated by the heat transfer of the engine coolant, so there is no additional fuel consumption!

How to turn on the heater if the car does not turn on the air conditioner:

Do not turn on the air conditioner in a hurry after the car starts, wait until the engine water temperature gauge pointer reaches the middle position, and then turn on the heater.

A C is the abbreviation of air condition, it is the switch of the air conditioner and refrigeration, and there is no need to turn on a c when turning on the heater.

The temperature of the warm air can be controlled at about 18 25. First, this is the most comfortable temperature for the human body, and second, if the temperature is high, the engine may need to do extra work to generate heat, which increases fuel consumption.

If you feel that the air in the car is a little turbid and the oxygen content is decreasing, you can adjust it to the external circulation.

Prolonged use of air conditioners increases the burden on the condenser and causes wear and tear on the refrigeration system. Therefore, you can turn off the air conditioner at the right time, let it "take a break and rest", and turn it on again after a while.

This not only reduces fuel consumption, but also avoids odors from the air conditioner. If the engine is turned off without turning off the air conditioner, it will cause mold to multiply in the air conditioner, and when it starts again, the vehicle will ignite with the pressure of the air conditioner starting, which will cause damage to the engine due to the high load.

There is no need to turn on AC, because car heating is achieved by generating warm air from the car's own engine.

Car heater opening method Sun Li:

Step 1: After the car starts, after about 8-15 minutes of rough sleepiness, the stool will be searched, the water temperature will rise to normal temperature, and the heater can be turned on at this time. (i.e. when the water temperature rises to the middle).

Step 2: Adjust the circulation mode of the air conditioner to the in-car circulation.

Step 3: Adjust to the warm air mode, do not turn on the air conditioner (do not turn on the AC switch), because the warm air is to use the car's own heat cycle to save energy.

Step 5: Adjust the air conditioning gear to fit the gear, adjust the wind direction of the air outlet, and use the air conditioning wind to transport heat to the entire cabin.

Do not turn on AC when the car is warmed up, the AC button is to start the compressor, and the compressor is to pressurize the refrigerant (fluorine). If you want to turn on the heater, of course, you don't need to move. Just adjust the air volume button to blow warm air.

At this time, the warm air uses the heat circulation in the car to transfer the heat emitted from the water tank to the cabin without increasing any fuel consumption! It is the key to AC refrigeration, and it is also the most air conditioning.

It is the key to AC refrigeration, and it is also the key to air conditioning, which requires manpower and waste oil the most. The air-conditioning hot air does not need to be "cooled" at all, and the car can be emptied by the heat generated by the engine. I've seen a lot of people turn the temperature up and press the "AC" key.

This is the typical opposite. Waste oil didn't say, and it wasn't hot.

Do not blow the heater directly on your face. Blowing directly on the face for a long time will cause driver fatigue, affect driving safety, and make the ** drier.

Pay attention to air circulation when opening windows slightly. Although the internal and external circulation can be adjusted, it is recommended to open the small gap in the window to circulate the empty air when the heating is used for a long time to ensure the oxygen content of the air inside the car and keep the driver clear.

Do you turn on the AC switch when the car heaters it?

In winter, you don't need to turn on the AC switch to turn on the heater. The air conditioner key is empty to switch the compressor. In summer, turn on the AC key empty, that is, turn on the air conditioner.

The heater only uses the heat cycle in the car and does not need to start the air compressor at all. Therefore, to turn on the heater, you only need to adjust the empty button, and there is no need to turn on the AC switch.

Warm air** heat generated when the engine is working: When the engine's cooling system dissipates heat from the engine, the heat emitted is sent into the car through the fan to form warm air; When the heater is not in use, the fan stops running, the hot air vent closes, and the heat is completely dissipated into the atmosphere. Therefore, car heaters are waste** and do not consume engine oil.

Precautions for car use air adjustment:

1.Turn off the air conditioner when starting and accelerating quickly. Because the on-air switch (non-independent no-switch) consumes a portion of the engine power, it is best to turn off the AC switch when the vehicle starts and accelerates rapidly, and then turn on the AC switch after the vehicle is moving.

This does not result in a lack of engine power during acceleration and starting, and saves fuel.

2.Controls the direction of the air outlet. Based on the principle that the cold air air sinks and the hot air air rises, when the owner controls the air outlet with air conditioning, the air outlet goes up when the air conditioner is turned on, and the air outlet goes down when the heating device is turned on.

3.Do not open the empty immediately after sun exposure. After exposure to sunlight, the temperature inside the car is usually high.

When the car owner encounters this situation, do not immediately activate the empty switch. It is best to open the window for ventilation first, and then turn on the empty switch after the hot air is exhausted. Do you want to turn on the AC switch for the heater in the car @2019

The heater does not need to be turned on a c, but for some automatic air switches, even if a c is turned on, a c will not work when the set temperature in the car is lower than the outside temperature!

The air conditioner of the car is actually the abbreviation of the English cracked tung of the air conditioner, which means air conditioning compressor. Since the energy of the air conditioning compressor comes from the drive of the engine belt (electric vehicles are driven by an electric motor), the power of the compressor is usually 2-3kw, so some power is lost. Usually, when the car's electronic control unit detects [ k0, it also increases fuel consumption.

Generally, the smaller the engine displacement, the more obvious the increase in fuel consumption. For small displacement engines, if the air is continuously turned on, the fuel consumption may increase by about 1L, while for the above large displacement engines, the effect of the air on fuel consumption is not obvious.

The car's warm air heat comes from the engine's waste heat, which is designed for both premium and low-end cars. Normally, when the warm air is turned on, only the heat from the engine tank needs to be blown into the cab through the fan, while the A C controls the empty compressor and takes the source liter, so there is usually no need to turn on the A C.

For manual air conditioners, since there is no automatic temperature control system, once the AC button is pressed, the electromagnetic clutch of the air conditioning compressor is powered, and the compressor will run regardless of whether hot or cold air is required. Ageing.

For automatic air conditioners, the empty A C button, although it will turn on the power of the electromagnetic clutch, is only a control switch. Whether the empty compressor is running or not will be automatically controlled according to the temperature you set. For example, the outside temperature of the car is 10, and the temperature you set is 15.

Because the temperature inside the car is higher than the outside, the electromagnetic clutch of the AC does not actually open. It will only actually operate if the set temperature is lower than the outside temperature.

You don't need to turn on the AC when the car is on the heater.

The A C button is the compressor start button of the car air conditioner, and the refrigeration needs to be turned on. The heating of the car air conditioner only uses the heat generated by the heat cycle inside the car engine for heating, and there is no need to start the air conditioning compressor at all, so there is no need to turn on the AC switch.

Because the air conditioner blows at a temperature that comes in directly from the engine afterglow, turning on the air conditioner key means turning on the compressor.

At this time, the air blown out by the air conditioner is about the same temperature as you set, and the incoming air will have a mixture of hot and cold air. In this way, the temperature of the air conditioner can be adjusted to about the same as the set temperature. So in order to save fuel consumption, you can manually turn off the AC button to stop the compressor, which can reduce the fuel consumption of the car to a certain extent.

As for temperature regulation, it can be achieved by adjusting the power of the blower.

When we need to blow warm air, the damper opens and the airflow is directed to the warm air box after passing through the evaporation box, and then heated by the high warm bellows and sent to the cockpit. We have warm winds. It can be seen that if the air conditioner switch is turned on when the heater is turned on, the air conditioner evaporation tank will produce a low temperature.

At this point, the ambient air is cooled first and then heated up by a warm air box.

What does the AC switch mean by the judgment of this car?

The AC switch of the car refers to the refrigeration switch of the car air conditioner, when the key is pressed, the compressor of the air conditioner will work quickly, and the wind blown by the blower will be cold air.

For example, in the summer, if you need to lower the temperature in the car, press the button and turn the temperature selector switch to the blue part, and then a cold air blows out. If you are equipped with an automatic air conditioner, simply press the button and then press the auto button.
