What happens to the air conditioner heating after the car is ignited

1.The vehicle has just started, the engine temperature has not yet risen, and it is OK after the car is warmed.

2.Lack of coolant, insufficient coolant will also cause the car air conditioner not to heat, just add coolant.

3.The water pump is damaged, resulting in the failure of the coolant circulation system, and it will also cause the car air conditioner to not heat, so the water pump can be replaced.

4.The warm air water tank is blocked, and the hot water inside the engine cannot be circulated in the water tank, causing the air conditioner to not heat up, and the warm air is cleaned.

5.If the radiator fan fails, the radiator fan will continue to dissipate heat, which will make it difficult for the coolant inside the water tank to heat up, and the air conditioner will not heat.

1. After the car is turned off, you don't turn off the air conditioner, and you still set it in the hot windshield. Of course, the air conditioner heats up after the car is ignited.

2. If the air conditioner is turned off, it means that the control system that controls the hot air damper is broken or the control system that controls the hot air damper is faulty.

If you have just started it, turn on the air conditioner and if you get hot air, it is obvious that the air conditioner is not working or the ice is running out. Further tests are done. Just think about it.

Just started the car, the water temperature is not up, how can it be hot. The second is that if your car has been started for a long time, you have to turn on the air conditioner and emit hot air, then you may hit the hot swirl ring. The air conditioner does not work.

I'll teach you a trick to see if the compressor is away from the piece and has not returned. Second, you touch the low pressure of the evaporator with your hand, and if it is very ice, the hand indicates that it is working.

You didn't choose the right hot and cold mode, put it on top of the hot air, and the heating began.

It's normal, you set it on the heating gear, although the fan is not turned on, but it is set to external circulation, and it will be the same.

The way to drive an air conditioner in winter is:

1. After the car starts, after 3-5 minutes of normal operation, the heater can be turned on;

2. First adjust the circulation mode of the warm air to the circulation in the car;

3. Then rotate the blowing mode to warm air mode, red means warm air, blue means cold wind;

4. Turn on the air conditioner to increase the temperature of the heater, that is, press the A C switch;

Generally, the air conditioning switch of a car is a rotary button, which can adjust the size of cooling and heating.

1. The air conditioning switch of the general car is a rotary button, which is divided into two ends, one end is the blue for refrigeration, and the other end is a red light for heating.

2. If you need to turn on the air conditioner in summer, then you need to rotate the air conditioner switch to the blue end, and you need to turn on the AC switch to let the compressor work for cooling.

3. If you need heating in winter, you need to turn the button of the air conditioner switch to the red end, and you don't need to turn on the AC switch. When the air conditioner is not in use, turn it off.

4. Whether it is to turn on the refrigeration or heating, you need to adjust the gear of the air conditioner according to your own situation, and feel that the positioning of the heat conditioning and cooling is higher, if it is cold, then you need to adjust the heating gear more.

Precautions for turning on the heating of the car air conditioner:

The AC switch does not need to be turned on when the car air conditioner is heated, because the heating on the car does not need the compressor to work for heating, and the hot air dissipated by the engine is directly used as heating, so there is no need to punch in the AC switch when the heating is turned on in winter.

However, when using the heating in winter, you can't close the windows for a long time, because the engine will produce a lot of harmful gases, such as carbon monoxide and other gases, which may poison people or even die, so you need to remember to change the air in the car when you turn on the heating in winter.

How to turn on the hot air of the car air conditioner: start the car, and after the car engine runs for a period of time, the water temperature rises to normal temperature; Find the in-car cycle button and press this button to adjust the cycle mode of the air conditioner to in-car circulation; Rotate the temperature control knob to the red area and adjust the wind speed switch.

In the process of using the heater, it is not advisable to turn on the heater as soon as you get on the car, because the water temperature of the engine is very low in the cold start state of the car, and turning on the heater in this state will not only not heat up quickly, but will slow down the heating speed, and also increase the burden on the engine.

The correct way is to preheat the car first, wait for the temperature pointer to reach the middle position before using the heater, and at the same time set the air circulation to external circulation, wait for a period of time, and then open the inner circulation of the car He Zhengpei, which can quickly increase the temperature in the car. When using the warm air, you should pay attention to the wind direction of the warm air, and do not blow it on the head for a long time, otherwise Zen Wei will cause driver fatigue.

Precautions for the use of car air conditioners are:

The temperature should not be too low; control the direction of the air outlet; Do not use for long periods of time; Appropriate opening of large air volume; Turn off the air conditioner when driving at low speeds.

Automobile air conditioning is to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in a suitable state, provide a comfortable riding environment for the occupants, and reduce fatigue during the journey; Ventilation devices that create good working conditions for drivers and play an important role in ensuring safe driving.

Because the air conditioner can be cooled by the rotation of the compressor, and the rotation of the compressor needs to be driven by the engine, there will be cold air only when the engine rotates when ignition.

When the temperature reaches the set temperature, the compressor electromagnetic clutch is released and the compressor stops working. When the temperature rises, the electromagnetic clutch engages and the compressor starts working. Constant displacement compressors are also controlled by the pressure of the air conditioning system, and when the pressure in the pipeline is too high, the compressor stops working.

The natural wind sent by the air conditioner is blown by the blower when the car is not ignited, because the air conditioning compressor is driven by the power of the engine, and the compressor will naturally not work when the car is turned off.

The natural wind blown by the blower is driven by the battery, and the final blower consumes too much electricity in the battery, which may cause the battery to lose power for a long time, which is only for traditional fuel vehicles.

This can be enabled by following the steps below.

1. After the car starts, preheat the training engine, open the window for a while, and then turn on the air conditioner.

2. Adjust the air conditioning cycle mode to the in-car cycle. The internal circulation can make the car heat up quickly, and then it can prevent the polluted air from entering the car on smog days.

3. Turn the air conditioner to warm mode. Some cars show the red demolition area, and some cars show the sun.

4. Be careful not to turn on the AC switch of the air conditioner, the AC switch button is used for cooling, do not turn on the heater, otherwise it will only increase your fuel consumption.

5. Adjust the appropriate air conditioning gear and adjust the blowing position, specifically look at the switch icon, blowing feet, blowing front glass, blowing pneumothorax, etc.; Air conditioning source, inside the car, outside the car.

Summary. Hello dear for your question. Pro, the reason why the car air conditioner heats normally but does not refrigerate:

1. Lack of refrigerant; 2. The condenser is too dirty; 3. There is water in the refrigeration system; 4. The compressor drive belt is aging or relaxed; 5. Damage to the air-conditioning compressor or expansion valve; 6. The air conditioner flap is damaged.

After the car is ignited, the air conditioner heats up, and the refrigeration does not work.

Hello dear for your question. Pro, the reasons why the car air conditioner heats normally but does not refrigerate: 1. Lack of refrigerant; 2. The cold side condenser is too dirty; 3. There is water in the refrigeration system; 4. The compressor drive belt is aging or lacks relaxation; 5. Damage to the air-conditioning compressor or expansion valve; Fu Qitong 6, the air conditioner flap is damaged.

Pro, the main reasons are as follows: 1. The motor of the air conditioning flap is damaged, and the general car air conditioning flap is under the dashboard, which belongs to the general switch of the air conditioning tuyere. If the air conditioner flap motor is damaged, it will cause the air conditioner to heat but not cool. In view of this situation, it is necessary to go to the 4S shop for repair in time.

2. The lack of refrigerant in the air conditioner will also cause the phenomenon of not controlling hunger and starting cold when the air collapses and the lack of refrigerant is adjusted. Under normal circumstances, the air conditioner needs to be added once in time every 2 to 3 years, but the time of adding the refrigerant will be different depending on the model of the car. In this case, only the refrigerant needs to be added in time.

3. The air outlet of the air conditioner is blocked by foreign objects, which will also affect the refrigeration of the automobile air conditioner. Car owners should regularly check the air outlet of the air conditioner to see if there are foreign objects blocked, once there are foreign objects blocked, only need to clean these foreign objects.

Summary. Car air conditioner, turn on first when heating, or turn on after heating: dear, hello, car air conditioning heating is best to start the car once before turning on the heating function.

The car air conditioner should be turned on first when heating, and then turned on after it is hot.

Is the front windshield defogging and heating used separately?

Car air conditioner, turn on first when heating, or turn on after heating: dear, hello, car air conditioning heating is best to start the car once before turning on the heating function.

Dear, the front windshield defogging and heating are not separated, they are all unified, if you open the warm air front windshield is also blowing heating.

The correct way to open the car air conditioner heating is: 1. The heater can be turned on after 8 to 15 minutes after the car is started; 2. First use the external circulation to discharge the cold air in the car, and then adjust it to the internal circulation after 2 to 3 minutes; 3. Adjust to the warm and cautious mode of respecting the wind; 4. Adjust the air conditioning gear to the appropriate gear and adjust the wind direction of the air outlet; 5. The direction of warm wind blowing is forward and under the feet. Automobile air conditioner, also known as automobile air conditioning device, is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in a more chaotic state.

The functions of automobile air conditioning are: 1. Provide a comfortable riding environment for passengers and reduce fatigue during the journey; 2. Create good working conditions for drivers.

The car has just been hit, and turning on the front windshield defogging does not affect anything.

Dear, this has no effect, it is all normal operation, you can rest assured.

Dear, the weather is easy to fog, it is recommended that you take a towel to check before turning on the defogging, which will remove faster.

Turn on the front windshield to remove fogging, and after a few minutes the temperature goes up, turn it off again. And then turn on the warm air.

Yes, it will also cause the temperature difference between the inside and outside the interior and exterior if it is always open, and it will also play a fogging inside and outside the glass.

Turning it off in the middle of the process will also play a fuel-saving state, and it will not affect the car.
