The air outlet of the car air conditioner is adjusted to blow the air upward, but there is no wind a

If the external circulation air volume is relatively small, and the internal circulation air volume is normal, it should be that the air conditioning filter is blocked. This situation requires a new cabin air filter element to solve the problem.

If the air volume is small regardless of internal and external circulation, it may involve problems such as internal air duct reproduction. This situation is not as prone to arise as the previous one. It is advisable to check the cabin air conditioner filter first. Replace the air conditioner filter, the air conditioner filter is too dirty, blocking the air conditioner air into the car.

How car air conditioners work:

The automotive air conditioning and refrigeration system consists of a compressor, a condenser, a liquid storage dryer, an expansion valve, an evaporator and a blower. Copper pipes (or aluminum pipes) and high-pressure rubber pipes are connected into a closed system between the components.

When the refrigeration system works, the refrigerant circulates in different states in this closed system, and each cycle has four basic processes:

1. Compression process: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses it into high-temperature and high-pressure gas and discharges it out of the compressor.

2. Heat dissipation process: high-temperature and high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid and consumes a large amount of heat.

3. Throttling process: After the high-temperature and high-pressure refrigerant liquid passes through the expansion device, the volume increases, the pressure and temperature drop sharply, and is discharged from the expansion device in the form of mist (small droplets).

4. Endothermic process: the vaporizer liquid enters the evaporator, so the boiling point of the refrigerant is much lower than the internal temperature of the evaporator, so the refrigerant liquid evaporates into a gas. During the evaporation process, a large amount of heat is absorbed from the surrounding area, and then the vapor of the low-temperature, low-pressure refrigerant enters the compressor.

This process is repeated to reduce the temperature of the air around the evaporator. Hope!

The air outlet of the car air conditioner is adjusted to blow the air upward, but there is no wind at the air outlet, and see if the pipe inside is falling off or blocked.

Hello, first check the air outlet switch, whether it is turned on, look.

Hello, all the wind is up, you can't feel it, if my answer is helpful to you, please set it to.

Because the device components connecting the air duct mechanism are detached.

A modern air conditioning system consists of a refrigeration system, a heating system, a ventilation and air purification device, and a control system.

1. Ventilation system: its function is to ensure indoor ventilation when the car is driving, that is, to continuously rush fresh air into the car room to drive away dust, carbon dioxide and harmful gases from the engine. During the cold winter months, fresh air should also be heated to ensure that the indoor temperature is suitable.

2. Heating system: its function is to heat the air in the car room or the fresh air entering the car room from the outside to achieve the purpose of heating and dehumidification.

However, it is possible that the air outlet of the air conditioner has been accidentally turned off, because the air outlet of the air conditioner in many cars can be controlled separately. The temperature of the car is best adjusted to a most suitable state, open the air conditioner can not only provide a good driving environment for the driver, but also reduce the fatigue of driving, if the air conditioner fails to repair as soon as possible, it is best to go to the repair shop.

How to use the air conditioner in the car in life?

In our daily life, turning off the air conditioner five to ten minutes before the engine goes out is of great help to the life of the air conditioner. Don't turn on the air conditioner too early when you just get in the car, if you park it in a place exposed to the sun, the cooling effect of turning on the air conditioner directly is not very good, so you should first adjust the car to the external circulation, and when the heat comes down, you can turn on the air conditioner, which will be much cooler and the cooling effect will be better.

Because the device component connecting the air duct mechanism is off.

All car air conditioning outlets have a wind direction transfer switch, which is connected to the air duct transfer mechanism. Check whether the switch has been turned to the position of the middle air outlet, or the device component connecting the air duct organ has come off, which is to disassemble the fan under the dashboard for repair, it is recommended to go to the repair shop for maintenance.

The maximum possibility is that the valve of the air outlet is closed, and the air outlet rules of the air conditioning duct are from far to near, and the air conditioner first fills the air duct with the pressure of the pressure head, and then squeezes each other through the flowing air and sprays out from the air outlet.

It's normal, do you blow hot air in winter and turn on a c?? If the air conditioner is not turned on, of course, the hot air will blow hot air, and in the case of external circulation, even if the fan is not turned on, the air conditioning outlet will be divided when there is a certain speed, unless you turn off the air outlet.

The following reasons are as follows:

1. The pipeline in the air outlet of the vehicle is blocked.

2. Air conditioning control residual leakage panel.

The adjustment of the position of the air outlet fails.

3. Air conditioning system.

Didn't work properly.

4. The control panel of the air conditioner is damaged.

5. The air conditioner filter is too dirty.

6. Air conditioning compressor.

Lack of refrigerant. 7. The vehicle did not start.

When there is no air outlet for the air conditioning outlet.

A 2009 BMW 325i sedan with a mileage of about 120,000 kilometers, model E90, N52 L engine. The owner told us that when the car was using air sound, there was no air coming out of all the air outlets.

Fault diagnosis: According to the fault phenomenon described by the owner, the maintenance personnel first turn on the air adjustment switch and adjust the fan speed control switch on the air conditioning control panel. It was found that except for the air adjustment outlet, other functions and operations can be displayed normally.

Connect to the Fault Diagnosis System (IS ID) for vehicle testing and null adjustment system to not store faults**. The car is equipped with automatic thermostatic air conditioning (IH ka), and the required air flow is generated by a fan, which is mounted behind the air circulation damper of the fresh air air bucket with heating and cooling adjustment (fan intake layout). The output of the fan is mounted directly on the housing of the fan motor.

There are two main circuits of air adjustable fan control: one is that the air adjustable control unit effectively transmits the PWM signal (PWM signal) to the output stage of the fan through the junction box electronic device (JBE), and the fan output stage controls the operation of the fan motor and adjusts the relevant wind speed according to the PWM signal; The other is eight damper motors connected in series, which controls the refrigeration and heating air regulation through the LIN line. Each damper motor has a measuring resistance of about 1, through which the lower damper motor is connected to the front damper motor.

According to the fault phenomenon and combined with the control principle of the E90 CAR air conditioning system, the possible fault points are: the air conditioning control unit, the fan output stage, the signal line between the air conditioning control unit and the fan output stage, the fan motor, the control line from the fan output stage to the fan motor, the power supply and grounding wire of the fan output stage, the LIN line of the damper motor, etc.

Finally, the junction box electronics (JBE) are not measured, but in general, the JBE is not damaged in terms of failure probability. In order to verify this judgment, the two terminals connected to the X1 4271 terminal 18 and the connector X14272 terminal 23 on the JBE were singled out, and the two terminals were directly shorted with jumpers. The air outlet is normal, and the wind speed can be adjusted.

Therefore, it can be judged that the fault location is the damage to the junction box electronic package (JBE).

Epilogue. The above is the relevant introduction to the empty air outlet, and the basic reasons for the failure of the empty air outlet are described above. After the owner reads it, it can be repaired if necessary!

There is a problem with the built-in system of the air conditioner; The second is that the air outlet of the air conditioner is blocked; The second is that the car does not have the corresponding fuel. In the author's opinion, there are three main situations.

First, there is a problem with the built-in system of the air conditioner

For many air conditioning built-in systems, many times it is necessary to replace or maintain them accordingly, because the air conditioner can only ensure the normal use of the air conditioner after obtaining the corresponding maintenance treatment, and can play a maximum effect of the air conditioner, so many times for the air conditioning system, it is necessary to maintain it accordingly, through reasonable maintenance and regular maintenance, in order to achieve a best use effect and purpose.

Second, the air outlet of the air conditioner is blocked a lot

In many cases, for some car air conditioners, because the owners are not accustomed to the usual car owners, or the sudden change in the weather, the car owners will be blocked by the corresponding air outlets, so in many cases for the owners of the car, more often it is necessary to check whether the air outlet of the air conditioner is blocked, because the air outlet of the car is blocked will cause the corresponding failure, and some hot and cold air services of the air conditioner cannot be enjoyed.

3. The car does not have the corresponding fuel

In many cases, after the car no longer has the corresponding fuel, it will appear after starting the car, and suddenly or once it starts, the car air conditioner cannot be used, so in many cases, the owner of the car needs to deal with it accordingly, refuel it in time, and check it accordingly, only in this way can the car be prevented from being unable to use the air conditioner because of some fuel problems.

Precautions: For many car owners, it is necessary to carry out regular maintenance of the car when needed, and to replace the corresponding parts, only in this way can the car get the corresponding power to better drive safely, and to achieve a better use state.

It is very likely that the air conditioner is blocked, resulting in the air inside can not come out, you can drive the car to the 4S shop to check it, let the professional technicians check the fault.

If the air conditioner outlet on the car does not ventilate, it may be that the switch of the middle air outlet is not open, or the filter screen is seriously blocked, or the fan fuse is broken or the relay is broken.

There is a problem with the air conditioning system, and in this case, you can pull the car to the repair shop and let a professional master help you fix it.

The following reasons are that the air outlet of the car air conditioner does not ventilate:1. The pipeline in the air outlet of the vehicle is blocked.

2. The position adjustment of the air outlet of the air conditioning control panel fails.

3. The air conditioning system is not working properly.

4. The control panel of the air conditioner is damaged.

5. The air conditioner filter is too dirty.

6. The air-conditioning compressor lacks refrigerant.

7. The vehicle did not start.

The air outlet of the car air conditioner may not be able to vent because of the failure of the blower, the blockage of the air conditioner filter, and the failure of the control system.

1. The blower is faulty

The blower is the core component of the air conditioner, if it is damaged, the car air conditioner will not be able to get air. The failure of the blower may be due to overheating damage to the internal coil or damage to the capacitor, and we can listen to the sound of the blower by turning on the air speed and volume of the car air conditioner to the maximum to determine whether it is faulty. Once there is a fault, it is necessary to go to a 4S shop or repair shop to repair it, and it is not possible for ordinary people to do it themselves.

2. The air conditioner filter is blocked

Clogged air conditioner filters are one of the above-mentioned causes of air duct blockage, and it is also the most common one. The air outside the car will be filtered by the air conditioning filter before entering the car, which will absorb a lot of debris in the air, so it is easy to clog. You can remove the air conditioner filter to see if it is clean, and if it is too dirty, you can replace it yourself.

3. Control system failure

If it weren't for the above two reasons, there was a problem with the control system of the car air conditioner. Dampers, control switches, and car air conditioning computers may all be the cause of failure, which is difficult to judge and difficult to repair by yourself. If you encounter it, you should go to the 4S shop to repair it.

Automotive air conditioner component use

The automotive air regulator is generally composed of a compressor, an electric clutch, a condenser, an evaporator, an expansion valve, a liquid dryer, a pipeline, a condensing fan, a vacuum solenoid valve, an idle device and a control system. Automobile air conditioning refers to the device that adjusts the indoor air quality of the empty car, which is used to adjust the temperature, humidity, air velocity, air cleanliness, etc. So as to create a fresh and comfortable indoor environment for passengers.
