Recently, I feel that the air conditioner is getting less and less cool, what should I do

Causes and solutions:

1. Lack of freon, check to see if there is a leak, you can drop some water at the pipe joint of the car, bubbles will generally appear in the leakage, find the leakage to repair it, and then go to the car repair shop or maintenance shop to add freon.

2. The filter screen is too dirty, you can try to find the bypass valve on the filter element base of the filter screen, when the pressure difference between the two sides of the valve reaches a certain value, it can be opened, generally the oil flows into the main oil pipeline through this pipeline, and other related parts are lubricated with special lubricants for automobiles, so that it is almost the same.

3. If the antifreeze is not enough, you can ask the people nearby to see if there is a 4S shop or car repair shop, you can only find a professional car repairer to see, too little antifreeze will lead to a high engine working temperature, which will affect the refrigeration effect of air conditioning.

4. If the doors and windows of the car are not closed properly, carefully check whether the doors and windows of your car are not closed properly, resulting in the leakage of air conditioning, and closing them is other problems.

5. The air conditioning core is too old, if the air conditioning core of your car has been used for a lot of time, it may be a problem with the air conditioning core, and you will install it to buy an air conditioning core and install it yourself, and you will not only find a car maintenance shop and car repair shop.

6. If the pressure of the refrigerant is too great, check the pressure value of the refrigerant with a pressure gauge and clean the condenser by the way.

7. If the refrigerant is not enough, you can use the pressure gauge to check the lower pressure value in the case of landing, and carefully see whether the refrigerator is normal, if not, the refrigerant is not enough, and the cold air is not cold or windy if the refrigerant is not enough. If the refrigerant is not enough, find a car repair shop to add it. Oh.

1. The voltage of the power supply is not enough.

Solution: Maintain a normal supply voltage.

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

Solution: Make the power space of the air conditioner and the cooling capacity required to match it.

3. The external ambient temperature is too high.

Solution: Change the environment in which the outdoor unit is used (move away from the high temperature environment or make the surrounding air of the outdoor unit more easily circulated).

4. The copper pipe between the outdoor unit and the indoor unit is too long.

Solution: Minimize the length of the copper tube between the outdoor unit and the indoor unit of the air conditioner.

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

Solution: Clean and maintain the air conditioner to make the clean outdoor unit more tolerant of heat dissipation.

6. Freon is not enough (commonly known as not enough refrigerant).

Solution: Supplementing freon can solve the problem of air conditioning not cooling.

Aging. In general, the service life of the air conditioner is eight years, ten years, fifteen years, why do you say this, because if the air conditioner is used well, usually pay attention to maintenance, and clean it regularly, then the service life of the air conditioner can reach ten years, fifteen years, and if the usual use is not correct, then it is relatively normal to be able to use it for eight to ten years. And if when we use the air conditioner, the air conditioner does not refrigerate, then it is also possible that the air conditioner is aging, the service life is too long, and the internal structure and parts of the air conditioner can no longer drive the air conditioner to refrigerate the function.

Fluoride deficiency. We all know that when the air conditioner is an electrical product in use, it must have freon, but usually, everyone may be sloppy about freon, or have no concept, because many customers have encountered the situation that the air conditioner is not refrigerated, and after inspection, it is found that the air conditioner is missing freon. Therefore, if you do not check and add freon, it is very likely that the amount of freon in the air conditioner is not enough, so when the air conditioner is used, the refrigeration of the air conditioner does not work.

In normal times, we need to check and add freon to the air conditioner frequently.

The power is not large enough.

The size of different air conditioners is related to the space and size of the room, that is to say, the number of different air conditioners and the size of the room area are different. If we need to use the space of the room is relatively large, and the number of horses we buy is not enough, the power is not enough, so that the power of the air conditioner is not large enough, the refrigeration effect of the air conditioner is not good enough, so this is the reason why we say that the air conditioner is not refrigerated, when we buy the air conditioner, we need to choose the appropriate power of the air conditioner according to the specific space size.

In modern home life, almost every household will install air conditioning in the room, and air conditioning, as an electrical appliance that can adjust the temperature and make people feel cool, is welcomed and loved by many people. But in the process of using the air conditioner, many people feel not too cold, so let's introduce what is going on.

First, the air conditioner is not too cool.

1. First of all, it may be because the air conditioner is not adjusted to the state of refrigeration. Generally speaking, air conditioners will have cooling and heating modes, in winter, we will adjust to heating, and now that summer is coming, we will forget to adjust the mode, so that no matter how low the temperature is, it will not feel cool.

2. Secondly, it may be because the temperature is not adjusted to the right level. Generally speaking, if you want to feel cool in the summer, it is best to adjust the temperature of the air conditioner to below 24, and remember to turn on the ventilation mode so that cool air will blow out of the air conditioner.

3. If the air outlet of the air conditioner is blocked by something, the cold air can't blow out, and we can't feel cool. The air conditioner is easy to suck in a lot of dust when it is in use, which clogs the air outlet, and we need to disassemble it and clean it.

Second, how to choose an air conditioner.

1. Between fixed-frequency air conditioner and inverter air conditioner, inverter air conditioner can adjust the temperature to make us feel comfortable, and it is energy-saving and environmentally friendly, so if you want better performance, you can choose inverter air conditioner. Fixed-frequency air conditioners** are cheaper, but their performance is not as good as that of inverter air conditioners.

2. Sometimes merchants will recommend some cheap air conditioners to us, but the quality is not very good, and various problems will occur when using them, so when we buy air conditioners, we should choose brands with relatively large fame as much as possible, because generally speaking, the greater the fame, the better the quality, which has been tested by the market.

Summary: The above is for you to introduce the content of the air conditioner is not too cool, I hope it can help you, if this problem also occurs in the air conditioner at home, you can refer to the above content to choose the appropriate method to operate.

In summer, because the weather is relatively hot, almost every household will turn on the air conditioner for cooling. But if the refrigeration effect is not good, the air conditioner is equivalent to nothing, what is the reason why the air conditioner is not cooling? How do we adjust?

1. What's the matter if the air conditioner is not cold.

1. The air conditioner is not refrigerated, probably because the refrigerant inside is insufficient, because many air conditioners have been used for a long time, and the refrigerant inside will leak, which will cause the outdoor unit to run normally, but the house is relatively hot, and the wind blowing out is also hot.

2. It may also be because the filter of the air conditioner is blocked, and many family members have not cleaned the air conditioner, especially the filter screen is most likely to be blocked, once a lot of dust accumulates, it will cause the cold air to blow out, and naturally there is no effect.

3. Another reason is that the compressor of the air conditioner has poor capacitance contact, or the compressor is damaged, which will lead to the failure to operate normally, which will affect the effect.

4. It is related to the fact that the air conditioner has a temperature sensing head, if the resistance value changes, it will affect the outdoor machine, and it will also affect the refrigeration effect of the air conditioner.

Second, what should I do if the air conditioner is not cooled?

1. Be sure to clean the air conditioner before using it every year, because there is a lot of dust. Not only should the filter be cleaned, but also the dust on the radiator should be cleaned up, which will lead to better heat dissipation and better cooling of the air conditioner.

2. If it is because of the lack of freon, we need to fill the fluoride in time, because it will volatilize for a long time, and we can ask the brand service staff to add freon, which needs to be charged according to a certain pressure.

3. If the compressor has poor contact or failure, it is necessary to ask professionals to check and repair the cardinal door, and if necessary, the compressor may need to be replaced.

4. For the temperature sensing head of the air conditioner, this small part is very sharp and important, which needs to be inspected and repaired, and replaced if necessary, so as to improve the problem of poor refrigeration effect.

Summary: If you find that the air conditioning effect at home is not particularly good, you need to pay attention to check the above problems, check the faults one by one, and always find the reason for the first thing, so as to improve the problem of air conditioning not cooling.

1. Check the compressor of the outdoor unit, as long as one of them is not running normally, then you have to ask a professional to repair it. 2. Regularly maintain and maintain the air conditioner. 3. Check whether the doors and windows in the room are closed.

4. Check whether the wire joints are welded and wrapped with waterproof insulating tape. 5. Check whether the sensor is good. Reasons for this:

1. Due to the long-term use of the air conditioner, the filter screen is blocked due to regular cleaning, and the sediment will accumulate more and more in the long run, which eventually leads to the ** air conditioner not being refrigerated. 2. Some users often make the temperature adjustment switch wrong because they lack the common sense about the first air conditioner. In addition, the doors and windows of the room are not closed, which will also lead to the ** air conditioner not being refrigerated, and the air conditioner is required to be closed when it is in normal operation.

3. The line between the internal and external machine is also one of the frequent points of failure, if there is such a fault, it is recommended to check whether the joint of the wire is wrapped with waterproof insulating tape after welding, this suggestion is to let professionals operate to avoid danger. 4. The air conditioner temperature sensor is short-circuited or short-circuited, the plug-in contact is poor or the socket is desoldered, etc., the circuit board has leakage or the component leakage, etc., which will cause the air conditioner to not refrigerate, and the pressure protection is small at this time. 6. Power supply or voltage problems are more common in summer, because the electricity consumption in the hot summer is relatively large, which seriously exceeds the electricity load, and will also lead to the first air conditioner not to refrigerate.

There are many reasons why the air conditioner is not cool, first of all, it may be that the mode of the air conditioner is not adjusted, so you can use the air conditioner remote control to directly adjust the air conditioning mode to the refrigeration mode, and you can lower the temperature to about 26, so that the overall effect will be better. It is also possible that there is a leak of refrigerant in the air conditioner, so you can check the pipes and condensers of the air conditioning system, etc., if you find a problem, you can contact the manufacturer to add a new refrigerator. It is also possible that the inside of the air conditioning pump is damaged, so you can find a professional person to come to the door for maintenance, and if there is a problem, you can replace it directly.

The air conditioner is not cool to add fluoride first need to empty the fluorine of the fluorine channel, usually you can open the fluorine bottle directly, and then you need to deflate, the time of deflation can be kept at about 5 seconds, and then the fluorine tube must be connected, and the connection port must be tightened, otherwise it will leak. After the connection is completed, it is necessary to exhaust the air, and when the exhaust is finished, you can start to add fluoride directly. After filling up, the general instrument will automatically remind you, and you can collect fluoride at this time.

It should be noted that the whole process needs to be carried out in a refrigeration state, otherwise it is useless to add it, and after it is full, the valve must be closed, and then the relevant equipment can be taken away directly.

First of all, we have to find the reason to be able to effectively solve it, it may be that the air conditioner has been used for a long time, so the refrigeration effect is relatively poor. Under normal circumstances, the air conditioner is used for about 15 years, so the cooling effect may not be particularly good, so you need to replace the air conditioner with a new one. There are also some problems with air conditioning compressors, if the compressor can not work normally, then of course the temperature may not be able to drop, if it is a problem with the compressor, then you must find professional personnel for maintenance.

In addition, the air conditioner may also have a lack of fluoride after being used for a long time, so you can let the maintenance personnel add fluoride to solve the situation that the air conditioner is not cool.

There are many reasons, 1. Insufficient refrigerant. 2. The voltage of the electric source is unstable, and it is necessary to ensure that there is a stable voltage during operation, when the voltage is unstable, it may affect the operation of the air conditioner, especially during the peak period of electricity consumption in summer. 3. The radiator is not cleaned, the principle of refrigeration is to transfer the indoor heat to the outside with a radiator, if the radiator is not cleaned regularly, there will be a large amount of dust on it, resulting in it can not dissipate heat normally.

Suggested treatment: 1. Ask Heji to check whether the external rotation is normal, after a few minutes of operation, touch the copper pipe in the external machine with your hands, if the temperature does not rise, it proves that the air conditioning refrigerant is insufficient, and then you need to find air conditioning professional maintenance personnel to increase the refrigerant. 2. The power supply voltage is not stable, usually not up to the normal voltage, especially when the peak of electricity consumption is more likely to appear this sign, we can purchase voltage stabilization equipment to deploy, if the local voltage is extremely abnormal bumps, advocate contact with the power bureau management.

3. Sweep away the debris of the vent, observe whether the outer frame is loose, and observe whether there are some foreign objects in the ventilated grille, and keep the vent circulating; When cleaning the outside of the indoor and outdoor heat exchanger, when the indoor heat exchanger is cleaned, the panel is taken off, it is scrubbed with a cloth, and then the heat exchanger of the internal machine is washed with a brush, which also achieves the purpose of removing cracking and dust. 4. To clean the dust on the filter screen, first disconnect the power supply, take out the filter screen, clean the filter screen with water, the water temperature should not be higher than 40 degrees, clean it with a thermoneutral detergent, and then wipe it dry with a dry cloth; Cleaning dirt and accumulation, which is prone to accumulation of dirt when draining, should be disinfected regularly to ensure smooth drainage and prevent bacteria from multiplying.
