What is the reason why the car air conditioner is not too cool

There are several reasons why a car air conditioner is not too cool.

1. The compressor of the air conditioner is damaged, the compressor is an important part of the operation of the air conditioner, if the compressor cannot work normally, then the air conditioner cannot be refrigerated, and the owner needs to repair or replace the compressor in time.

2. The owner turns on the external circulation mode, because in the external circulation mode, the air inside and outside the car will circulate, and the high temperature in the car is normal, and the owner needs to switch to the internal circulation mode of the air conditioner, so that the cold air will not circulate to the outside of the car.

3. The refrigerant of the air conditioner is insufficient, resulting in the poor refrigeration effect of the air conditioner, and the owner needs to replenish the refrigerant in time.

4. The condenser, air filter and filter are blocked, resulting in abnormal work of the air conditioner, the owner needs to clean the condenser, air filter and filter in time, and after replacing the damaged parts, the air conditioner of the vehicle will return to normal.

Due to the poor air quality, it is easy to cause problems such as blockage of air conditioning parts, so it is necessary to maintain the car air conditioner daily, such as: compressor, air conditioning and refrigeration pipeline; evaporation tank and external circulation ventilation pipeline; cab, evaporation box and internal circulation ventilation pipeline, etc.

1. First of all, check whether the compressor is still working, if it is not working, then check whether it has been broken, if it is broken, you must replace it with a new compressor, the price of a compressor is about 500-1000 yuan. 2. Secondly, check the refrigeration pipe, detect whether it has leaked or damaged, and if it is broken, you need to replace the ventilation pipe again.

Too much refrigerant, resulting in a decrease in refrigeration efficiency. The refrigerant and refrigeration oil contain too many impurities, and a slight blockage occurs, resulting in insufficient refrigeration capacity. Too little refrigerant, insufficient refrigerant leads to insufficient refrigeration capacity.

If the condenser is too dirty, the compressor drive belt will also be relaxed, and the air conditioner will not be cold.

There are certain requirements for the proportion of refrigerant in the volume of the air conditioning system, if the proportion is too much, it will affect its heat dissipation, because the heat dissipation capacity is large, and the cooling capacity is small.

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

There are many reasons why an air conditioner does not refrigerate, the most common ones are:

1. If the air conditioner has no wind or the air volume is small, it is necessary to check whether the air conditioner filter is dirty, whether the blower can operate normally, and whether the air conditioner copy motor can be converted normally;

2. The freon of the air-conditioning system is missing, and it is necessary to check whether the system is leaking, and after the maintenance is confirmed, add freon to the standard range;

3. The condenser of the water tank is dirty, and the engine cooling system is faulty, resulting in high water temperature, such as the cooling fan not working, etc., resulting in poor heat dissipation of the water tank and the condenser;

4. The data of the air conditioning pressure sensor, evaporation box sensor and other sensors are wrong, resulting in the inability to adjust the air conditioning system correctly;

5. The adjustment solenoid valve of the air-conditioning compressor is damaged, the clutch of the air-conditioning compressor is damaged, and the internal of the air-conditioning compressor is damaged;

6. Caused by the failure of the air conditioning system line or control unit. When the car air conditioner is not refrigerated, you can choose a relatively professional maintenance organization for inspection and maintenance. For example, the 4S shop or brand repair shop of the model brand shall choose the maintenance organization according to its own actual situation.

Questions. Is the air conditioner not cool due to high water temperature?

Uh-huh. Questions.

What's wrong with the high water temperature.

The reasons for the high water temperature in the car are: 1. The thermostat is damaged, and the coolant is only circulated for a small time, and the heat is not dissipated through the water tank; 2. The cooling fan does not rotate, the temperature control switch is not turned on or the water temperature sensor fails; 3. The water pump is faulty, and the impeller slips or gets stuck, resulting in the belt breaking; 4. Insufficient cooling medium, insufficient coolant or water tank leakage; 5. The ignition timing is incorrect and the oil pressure is high, and there is a difference between the reading of the water temperature gauge pointer and the actual temperature; 6. The water tank is blocked, the external dirt is blocked, and the internal water channel is blocked to affect the circulation of coolant; 7. The cylinder is corroded, resulting in frequent water shortage in the water tank.

There are several reasons, the most common is that the system pressure is insufficient, the refrigerant is leaking, the refrigerant should be replenished, and the cause should be identified. Second, the pressure is too high, the main reasons are too much refrigeration, moisture or air in the system, too much refrigeration oil, and expansion valve failure. Third, the fan speed is too low.

In my experience, these are the common ones. I just graduated from Hubei Jiaotong Vocational and Technical College, majoring in automobile inspection and maintenance. The level is limited, please forgive me!

Causes and solutions for car air conditioners not to be very cool:

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 is broken, replace the thermostat.

5. The temperature sensor is broken, replace the sensor.

6. The compressor is broken, replace the compressor.

It should be that the refrigerant is leaking less, and in addition, look at whether the condenser (for heat dissipation) is very dirty and causes heat dissipation to be ineffective. If it's dirty, wash it too.

There are many reasons, it is estimated that the refrigerant is leaking, and the refrigerant is added.

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

When driving in summer, the most distressing thing for everyone is that they are afraid of heat and the air conditioner is not cool.

The solution to the car air conditioner is not cool.

Buy a car, use a car, maintain a car, repair a car, and listen to Chen Gong talk about cars.

I called the air conditioner repairer, and said that the air conditioner at home was gone, and it cost forty or fifty yuan.

How do I know if my compressor is oil-free?

Insufficient or too little refrigerant.

It can be observed from the sight glass above the drying tank that when the air conditioner is running normally, if there are continuous and slow air bubbles in the sight glass, the surface refrigerant is insufficient. If there is a significant bubble flipping, it means that the refrigerant is seriously insufficient. If the refrigerant is insufficient or too little, the solution is to add refrigerant, but be careful 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.

The maintenance cost is about 200 yuan.

The air conditioner's power supply is reversed.

Main performance: Generally, it will only appear when the car air conditioner is installed.

Workaround: Reconnect the neutral wire.

The fan or capacitor of the internal or external unit is damaged.

Main performance: If the external fan is broken, the main manifestation is that the exhaust temperature is too high or the high pressure is too high; If the internal fan is broken, it will be frosted in the internal unit.

Solution: Replace the damaged internal (external) fan or capacitor.

Refrigerant leakage or poor refrigerant quality.

Main performance: The internal and external units of the car work, and the compressor also works, but the car air conditioner has no refrigeration effect.

Solution: Check whether it is caused by leakage or quality problems of refrigerant in automobile air conditioning, and add or replace refrigerant in time.

Damaged or defective compressor capacitors.

Main performance: The internal and external units of the car are working, the compressor will not rotate, and it will cause overheating.

Solution: Check whether the compressor capacitor is in poor contact or damaged, and replace it in time if damaged.

Lack of refrigerant.

The loss of refrigerant is mainly leakage, if your car is not cool when the air conditioner is not cold, and it starts to be not cool after a period of time after adding refrigerant, then you have to pay attention.

If the condenser leaks, the condenser needs to be replaced, and the leakage is generally checked by adding fluorescent agent to the fluorine oil and checking it with special glasses to find out where the leakage is. There is also a relatively simple method suitable for when the leakage is more serious, you can see the condenser surface through the middle grid There is oil and dampness, and in this case, the condenser is generally leaking.

Precautions for refrigerant filling in automobile air conditioners.

In the process of filling the refrigerant from the high-pressure end, it is strictly forbidden to start the engine, but the user accidentally starts the engine and turns on the car air conditioner, and the high pressure is returned to the refrigerant tank, and the refrigerant tank cannot withstand such a large high pressure, resulting in the rupture of the refrigerant tank.

In the process of filling refrigerant from the low pressure end, it is necessary to start the engine and adjust the car air conditioner to the maximum, at this time, the high pressure valve must be closed, but the user negligently does not close the high pressure valve, or does not close the high pressure valve, or mistakenly wants to fill the refrigerant from the high pressure end, which will lead to the high pressure backflow into the refrigerant tank, and the refrigerant tank can not withstand such a large high pressure, resulting in the rupture of the refrigerant tank.

When driving in summer, the most distressing thing for everyone is that they are afraid of heat and the air conditioner is not cool.

The solution to the car air conditioner is not cool.

1. Check whether there is a lack of fluorine, 2, more than five years of motor vehicle compressor aging, 3, air conditioning compressor belt aging, 4, compressor failure, 5, more than three years without replacing the air conditioning filter, the filter element is blocked.

1.Insufficient or too little refrigerant is often caused by a refrigerant leak.

2.Too much refrigerant will also cause the air conditioner not to refrigerate, because the proportion of refrigerant in the volume of the air conditioning system is required, if too much, it will affect its heat dissipation.

3.The drive belt is loose, and the compressor will slip when working, resulting in a decrease in transmission efficiency.

4.There is water infiltration in the refrigeration system, resulting in insufficient or no refrigeration.

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

First check if the settings are correct.

1. Turn on Select Low Temperature, turn on the AC air conditioning button, select the air outlet speed, and open the air outlet.

2. When checking the air conditioner filter, the filter element is blocked, the air outlet is insufficient, and the air conditioning is insufficient.

3. The air conditioning system is not working well, it is not refrigerated, you need to enter the maintenance shop, and ask a professional technician for diagnosis.

The car air conditioner is not cool, it may be that there is something wrong with these places. Understand the car story of the car sister and the stupid black fat brother!

Summary. Hello. Friend.

Reasons why the car air conditioner is not too cool: lack of fluorine, dirty air conditioning filter, dirty evaporation box, dirty condenser, and problems with the air conditioning system, all of which will cause the car air conditioner to be not cold enough.

Hope it helps.

What is the reason why the car air conditioner is not too cool

Hello. The reasons why the car air conditioner is not too cool: lack of fluorine, dirty air conditioning filter, dirty evaporation box, dirty condenser, and problems with the air conditioning system, all of which will cause the car air conditioner to be not cold enough. Hope it helps.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.

1.Too much refrigerant leads to insufficient refrigeration:

If it is true that there is too much refrigerant, it can be slowly discharged from the maintenance port on the low pressure side of the air conditioning system.

2.Insufficient refrigerant:

From the viewing window above the drying tank, it is also observed that the refrigerant is insufficient. If it is insufficient, the refrigerant is added, but it is important to note that if it is added from the low pressure side, the refrigerant bottle is not allowed to fall. If it is added from the high-pressure side, it is forbidden for the engine to know and accompany the start.

3.The refrigerant has frozen, and too many impurities in the oil are causing insufficient refrigeration

If there is too much dirt in the refrigerant and refrigeration oil of the entire air conditioning system, it will inevitably clog the filter, resulting in a decrease in cooling capacity and an increase in resistance, resulting in a relative reduction in refrigerant leading to the expansion valve. Resulting in insufficient refrigeration.

4.Check the looseness of the compressor belt:

When the engine stops running, it is best to use your hand to toggle the belt in the middle of the drive belt so that it rotates 90 degrees. If the angle of rotation is too large, it means that the transmission belt is loose and should be tightened. If it is turned over by hand, it means that the transmission belt is too tight and should be slightly tightened.

5.The cooling capacity of the condenser decreases:

Due to the different working environment of the car, the surface of the condenser installed in front of the car engine will be covered with oil, sludge or debris, so that its heat dissipation capacity will be reduced.

1. Insufficient refrigeration caused by too much refrigerant

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.

2. Too little refrigerant leads to insufficiency

The lack of refrigerant is also observed from the upper field of view of the drying tank, if it is insufficient, due to the addition of refrigerant, but it should be noted that if it is added from the low pressure side, it is forbidden to pour the refrigerant bottle. If it is added from the high-pressure side, it is forbidden to start the engine and sell it.

3. The refrigerant has been frozen, and the impurities of the engine oil are too many to cause insufficient refrigeration

If there is too much dirt in the refrigerant and refrigeration oil in the whole air conditioning system, the filter will inevitably be blocked, resulting in a decrease in the refrigeration passing capacity, an increase in resistance, and a relative reduction in the refrigerant leading to the expansion valve. Therefore, the refrigeration is insufficient.

4. Inspection of loose compressor drive belt:

When the engine is stopped, in the middle of the drive belt with the hand to dial the belt, can turn 90 degrees for the bucket Senjia, if the rotation angle is too much, it means that the drive belt is loose and should be tightened, if it is flipped by hand and does not move, it means that the drive belt is too tight, should be slightly tightened.

5. The heat dissipation capacity of the condenser decreases

Due to the different working environment of the car, the surface of the condenser installed in front of the car engine will be covered with oil, mud or debris, so that its heat dissipation capacity will be reduced.
