What should I do if the air conditioner in the car seat does not have cold air?

1. The compressor lacks refrigerant, add refrigerant.

2. The compressor lacks oil, so you need to add some oil to the compressor.

3. If the refrigeration system line is faulty, check the line.

4. The thermostat interface is broken, replace the thermostat.

5. The installation position of the temperature sensor has changed, and the sensor is re-installed.

6. Compressor refrigerant leakage, check the leakage point and repair.

7. The refrigeration pipeline is blocked, clean the refrigeration pipeline.

Extended information: the first trick: don't blindly covet the low temperature of the air conditioner, the air conditioning temperature can be set appropriately, because the air conditioner in the refrigeration, the set temperature is increased by 2, you can save 20% of electricity, experts said that for people who sit quietly or are doing light labor, the indoor acceptable temperature is generally between 27 -28, so at this time, you can set the air conditioner to sleep gear, which can also save electricity.

The second trick: choose an air conditioner with moderate cooling power. An air conditioner with insufficient refrigeration power can not only not provide sufficient cooling effect, but also shorten the service life of the air conditioner and increase the possibility of air conditioner failure due to long-term uninterrupted operation.

So is it necessarily better to choose an air conditioner with more cooling power? Not really. According to reports, if the refrigeration power of the air conditioner is too large, the thermostat of the air conditioner will be switched on and off too frequently, which will lead to increased wear and tear on the air conditioning compressor; At the same time, it will also cause an increase in the power consumption of the air conditioner.

The third trick: close the doors and windows when the air conditioner is turned on. Do not open the door frequently in air-conditioned rooms to reduce the infiltration of hot air. At the same time, for air conditioners and window air conditioners with ventilation function, they can be ventilated without opening the damper when there is no peculiar smell in the room, which can save 5%-8% of energy.

What should I do if the air conditioner in the car is not cooled? It doesn't have to be a problem with the air conditioning system, sometimes the reason is simple.

If you are interested, don't miss it, hurry up and take a look!

The belt of the air conditioner compressor is too loose. If you turn on the air conditioner in the car and find that you can hear a "squeak" sound, then you should pay attention to the fact that the air conditioner does not cool down, which is probably caused by the compressor belt being too loose. In this case, we need to tighten the belt of the air conditioner compressor.

In addition, this belt is made of rubber, which has a certain service life, and needs to be replaced if it is too old to be used.

Insufficient refrigerant. The common refrigerant is codenamed R134A, and the consequence of insufficient refrigerant is to affect the refrigeration effect of the air conditioner, resulting in insufficient refrigeration. Generally speaking, the environment in which the refrigerant is located is relatively closed.

However, after the vehicle is used for a long time, the parts in the air conditioning system may be aged and worn, and the space where the refrigerant is located will leak, and the amount of refrigerant will be insufficient. So everyone should pay attention to check this as well.

The air conditioner filter is too dirty. We've also mentioned earlier that cabin air filters have an important impact on the air we breathe in and on our health. If the filter element is too dirty, it will not only cause many impurities in the air inhaled into the car, which is harmful to health, but also the dirty things will block the air conditioning filter, so that the cold air of the air conditioner will also be partially blocked, causing us to not feel the air conditioner cooling.

The condenser is too dirty. If the condenser is not cleaned, all kinds of impurities tightly wrap the condenser, and the condenser will not be able to dissipate heat normally. This is also one of the reasons why air conditioners are not cooling.

Seeing this, I believe everyone has an understanding of the reasons and solutions for the air conditioning not cooling in the car.

In the history of the development of the world's cars, the family of car consumption is the beginning of the economic car, and in most developed countries, the economic car is the mainstream of the family car market. In today's world, energy-saving, environmentally friendly and compact economic cars are favored by consumers, and the development of economic car industry is encouraged and supported by the best countries in various countries.

1. Too much refrigerant causes insufficient refrigeration.

Too much refrigerant is generally caused by overfilling the refrigerant during maintenance, because the proportion of refrigerant in the volume of the air conditioning system is required. If the proportion is too large, it will affect its heat dissipation, that is, the more heat dissipation, the greater the cooling capacity; Conversely, if the heat dissipation is less, the cooling capacity will be small.

Inspection method: Observed from the sight glass above the drying tank. If you can't see a single bubble in the sight glass when the car air conditioner is running, and there are no bubbles after the compressor stops, it must be too much refrigerant.

If there is too much pressurized cooling oil, cloudy air bubbles can be seen in the sight glasses when the air conditioning system is running normally. Of course, if there is too much refrigerant, you can slowly release some of it at the maintenance port on the low-pressure side of the air-conditioning system.

Second, too little refrigerant causes insufficient refrigerant.

Most of the causes of refrigerant deficiency are due to small leaks of refrigerant in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant injected into the evaporator from the expansion valve must also be reduced, when the refrigerant evaporates in the evaporator. As a result, the amount of heat absorbed will decrease, and so will the cooling capacity.

Maintenance method: Insufficient refrigerant can also be observed from the sight glass above the drying tank, when the air conditioner is running normally, if there are continuous slow bubbles in the sight glass, the refrigerant is insufficient. If there is a significant bubble flipping, it means that the refrigerant is seriously insufficient.

If the refrigerant is insufficient, the refrigerant should be added, but it should be noted that if it is added from the low-pressure side, it is forbidden to pour the refrigerant bottle, and if it is added from the high-pressure side, it is forbidden to start the engine.

3. There is air in the system that leads to insufficient refrigeration.

Once air enters the air conditioning system, the pressure of the refrigeration pipe will be too high, and the poor refrigerant circulation will also cause insufficient refrigeration. Such failures are mainly caused by poor sealing of the refrigeration system, or incomplete evacuation during maintenance.

Fourth, other reasons lead to insufficient refrigeration.

Failures such as insufficient refrigeration and poor refrigeration effect in the air conditioning and refrigeration system are generally due to more common problems in refrigeration sealing. Because the refrigerant used in cars today is highly permeable. Therefore, the sealing requirements for the system are correspondingly high, and the slight leakage in the refrigeration pipeline or working valve will cause insufficient refrigeration failure.

In the summer, air conditioning is one of the must-have hardware for cars. Summer is a period of high incidence of car air conditioning failures. If your car's air conditioner suddenly strikes under the scorching sun, you may want to enjoy the "free sauna". Therefore, car owners who neglect to take care of their cars should carry out certain maintenance of air conditioners.

Generally, in the case of poor air conditioning in the car air conditioner, we have to check whether the belt of the car air conditioner is loose, loosening will cause the car compressor to work abnormally, in addition, we must check whether the electronic fan of the air conditioner is working, if the work is not good, the electronic fan will dissipate heat, which also leads to the abnormal operation of the air conditioning system, and also check whether the refrigerant (refrigerant) refrigerant is enough, we can use a professional refrigerant filling machine to check the working condition of the high-pressure pipe or low-pressure pipe. We can use the feel to check the temperature of the general high-pressure pipe is a little hot, if the low-pressure pipe has a good air conditioner, there will be water droplets (attached) phenomenon, which means that the air-conditioning system is relatively normal, if there is no above phenomenon, it means that the air-conditioning system is abnormal, we must go to the professional maintenance station to repair and check whether the refrigerant is enough, whether the heat dissipation system is good, we can use the car refrigerant filling machine to detect the low-pressure pipe and high-pressure pipe of the car, first of all, we look at the high-pressure gauge, If the high pressure gauge is too high, it may be that the heat dissipation system of the air conditioner is not good, and then look at the low pressure gauge, if the low pressure gauge indication is insufficient, it may be that the refrigerant is not enough, at this time, the refrigerant must be added, if it is confirmed that the refrigerant is not enough, it is necessary to add the car special car refrigerant, I personally think that there are several key points, is that the owner must pay attention to the car after the car is exposed, when starting the car, do not turn the car air conditioner to the maximum gear, but to properly adjust the temperature of the air conditioner, it is best to open the door or window, When the air in the car cools slightly, close the windows, and when using the car air conditioner, you must also use the start program correctly, and normally start the engine first. Then turn on the air conditioning system when the car turns off before stopping. We have to turn off the air conditioning system and then turn off the engine, hoping that the riders can have a cooler summer!

The air conditioner on the car does not produce cold air, that is, there is no refrigeration, reasons and solutions:

1. The compressor lacks refrigerant, add refrigerant.

2. The compressor lacks oil, so you need to add some oil to the compressor.

3. If the refrigeration system line is faulty, check the line.

4. The thermostat graft is broken, and the thermostat is replaced.

5. The installation position of the temperature sensor has changed, and the sensor is re-installed.

6. Compressor refrigerant leakage, check the leakage point and repair.

7. The refrigeration pipeline is blocked, clean the refrigeration pipeline.

1. The following are the reasons and solutions for the air conditioner on the car that is good but does not produce cold air: 1. Lack of refrigerant: The compressor of the car lacks refrigerant and needs to add refrigerant.

2. Line change and shouting fault: The line failure of the refrigeration system of the car needs to be checked. 3. Refrigerant leakage

Compressor refrigerant leaks need to be checked for leaks and repaired. 4. Blockage of refrigeration pipelines: The refrigeration pipelines need to be cleaned if the nuclear retardation pipeline is blocked.

2. The following are the functions of automobile air conditioning: 1. Temperature regulation: This is the main function of automobile air conditioning.

In summer, the cold air generated by the refrigeration system cools the cabin; In winter, except for large commercial vehicles, which are heated by independent combustion heaters, other vehicles basically use automobile waste heat for heating. 2. Humidity regulation: Humidity has a great impact on the comfort of the occupants in the car.

The humidity in the cabin should generally be kept at 30 -70 Ordinary car air conditioners do not have the function of adjusting the humidity in the car, only through the use of ventilation devices or the integrated air conditioners used in high-end luxury cars. 3. Airflow regulation: The flow rate and direction of airflow have a great impact on people's comfort and retention.

If the direct blowing temperature is suitable, the flow rate should be limited to a certain range, and the flow rate can be appropriately changed according to the passenger's living environment, age, health status, cold and heat habits, etc. 4. Air purification: The quality of the air in the carriage is an important guarantee for comfort.

The reasons why the air conditioner in the car is not cooling are as follows:

1. Freon is not enough (commonly known as "refrigerant" is not enough).

When the ambient temperature is about 35 degrees Celsius, 1, low pressure and high pressure 3, static pressure.

This is a normal situation, usually in the case of an old air conditioner that has been used for three to four years. The air conditioner did not completely stop cooling, but the effect of cooling decreased. This is because old air conditioners use freon as a refrigerant, which will volatilize after long-term use.

Therefore, users only need to add a little to the regular air conditioning maintenance point. In addition, it is not excluded that improper installation can cause freon leakage and problems with the machine itself.

2. The power supply voltage is insufficient.

The normal starting voltage of the air conditioner is 220V+-10%. In China's power supply system with a phase voltage of 220V and a line voltage of 380V, almost all compressors above 200V can be started. At 180V or more, 70-80% can be started, and at 160V or more, only a few can be started.

I've done it myself. Below 160V there is almost no possibility of starting. As a rule of thumb, the compressor starting voltage is more reliable above 190V.

3. The power of the air conditioner is not enough.

The general selection principle is: 150-250W square meters for cooling and 250-350W square meters for heating, in addition to comprehensive consideration of factors such as space height, level orientation, sealing performance and residential population.

4. The external environment temperature is too high.

There is a common saying: when the outdoor unit is in an environment above 43°, most air conditioners are difficult to transfer the heat from the indoor to the outside, resulting in no refrigeration.

5. The air conditioner is not cleaned and maintained for a long time.

If you want the air conditioner to operate normally and not affect human health, but also to prolong the life as much as possible, obviously, it is impossible to leave it alone as soon as you buy it and install it. Because the outdoor unit is exposed to the outdoors, it is easy to absorb dust and debris, and if it is not cleaned for a long time, it will affect the heat dissipation performance of the machine, resulting in the reduction of the cooling effect of the air conditioner. The indoor unit is related to the health of the human body, and if it is not cleaned for a long time, it will breed bacteria, pollute the air, and make people sick.

It is very likely that there is no fluorine in the air conditioner, and it is possible that the air outlet of the air conditioner is blocked.

If the air conditioning in the car is not cool, there are just a few problems normally:;

1. The radiator (condenser) is blocked.

2. The air conditioner filter is too dirty.

3. The evaporation tank is too dirty.

4. Lack of freon.

5. The compressor does not work.

6. The thermostat is broken, resulting in high water temperature and no heat dissipation.

1 3 generally does not say that you can't feel a cool breeze at all, this can be checked by yourself in combination with the situation, if it is not cool at all, then it is likely to be caused by 4 6. First look at whether the water temperature is too high, whether there is a water temperature alarm or spine report, and whether the water temperature lamp exceeds the standard line. If it is, the thermostat is broken.

If it's not the water temperature, then the wild group land is only 4 or 5 songs, so go to the repair factory.
