What are the causes and solutions of bad air conditioning

How to solve the problem that the refrigeration effect of air conditioning is not good.

1. If you have a problem with the temperature setting of the air conditioner, you can set the temperature with the remote control, and it is recommended to set the temperature when cooling: 26-28 degrees Celsius.

2. If there is a lack of air conditioning refrigerant (freon), you can find after-sales service personnel to check and add it.

3. The compressor problem can only be maintained by professionals, or consider buying a new machine.

4. If the air conditioner filter is blocked, it is best to clean the filter screen once in about 15 days.

5. Do not place items at the air inlet and outlet of the air conditioner, otherwise it will affect the refrigeration effect of the air conditioner, and foreign objects should be removed.

6. The size of the room should be considered when choosing an air conditioner, and if the room is too large, you can also use a cloth curtain and other partitions to reduce the room area.

7. If there is a heat source in the room that affects the refrigeration of the air conditioner, the heat source in the room should be kept at a certain distance from the air conditioner.

8. If the air conditioner is installed unreasonably, you can find the installer to reinstall and arrange.

9. If there is a quality problem in the newly purchased air conditioner, you can contact the merchant for replacement or maintenance.

1. Freon is not enough

This is a normal situation, the air conditioner is not disturbed early and completely not refrigerated, but the refrigeration effect is not good enough, this is because the old air conditioner is using Freon as a refrigerant, which will volatilize after a long period of use, in addition, it is not excluded that the improper installation causes the leakage of Freon and the problem of the machine itself.

Solution: In this case, it is necessary to add freon to slow the freckage, that is, it can solve the problem of air conditioning not cooling.

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

There are many reasons for the poor refrigeration of this air conditioner, such as: small power air conditioning pipes and large area of the room, and some although the air conditioning power and the room area seem to match, but because the room is relatively unsealed (such as doors and windows are wide open, etc.), or there is a heat source in the room (such as many computers), of course, the glass room is also one of the heat sources, and so on.

Solution: When purchasing an air conditioner, estimate the practical area, and if the funds are sufficient, you can add the number of horses on the basis of the appropriate number of horses.

3. The power supply voltage is not enough

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. Below 160V there is almost no possibility of starting. As a rule of thumb, the compressor starting voltage is more reliable above 190V.

Solution: The situation caused by the air conditioning refrigeration is not good, need to check the power supply, if the grid voltage is too low, the user should install a power regulator, so that the voltage reaches 220V, so that the air conditioner can be used normally.

Not enough power

That is, we often say "buy small"! Forty or fifty square meters of space only bought a hang-up, and even if it is in good condition, the cooling effect is very limited.

Solution: The air conditioner should be selected according to the cooling capacity, the cooling capacity required for the confined space of the bedroom is 150 180W, and the cooling capacity required for open spaces such as the living room is 180 220W - generally according to 150W and 180W to choose, if there are special circumstances such as Xizhao, it needs to be increased as appropriate.

5. The air conditioner filter is too dirty

The air conditioner filter was originally designed to prevent indoor dust from entering the inside of the air conditioner and causing damage to the internal components. However, after a long time, the surface of the filter screen blocked at the air outlet is covered with dust, which affects the exchange of hot and cold air, which will inevitably slow down the refrigeration speed.

In addition to the filter screen of the indoor unit, the radiator of the outdoor unit is also a major problem - the outdoor unit needs to dissipate heat through the radiator, and if there is debris on the radiator (usually not dust, but garbage such as plastic bags), it will greatly affect the cooling capacity of the air conditioner.

Solution: Whether it is an indoor unit or an outdoor unit, it needs to be cleaned regularly. When cleaning the indoor unit, if it is too dirty, you need to use a professional cleaner (search for it on the Internet); If you clean it once or twice a year, you only need to take the filter off and rinse it.

There are six reasons why the air conditioner is not refrigerated properly in <>: the air conditioner cannot start normally due to low voltage; Poor plug contact, resulting in a large current in the machine code failure, overheating of the shrinkage machine, and unable to work normally; The heat dissipation of the external unit is not good, resulting in insufficient fan speed and poor heat dissipation; The starting capacitor of the compressor is faulty, resulting in the compressor being unable to start normally; There is not enough refrigerant; The inner filter is too dirty.

After the advent of summer, only if you move lightly will sweat the rhythm, it can be said that at this time you will feel the importance of air conditioning, generally speaking, at this time only the fan can not solve the problem, only the air conditioning can help you solve this problem, but at this time if there is a problem with the air conditioner what to do. The following will introduce to you the reasons for the poor refrigeration of air conditioning and teach you how to solve the problem of air conditioning not refrigerating.

One of the reasons for poor air conditioning refrigeration: Generally speaking, it is caused by insufficient freon (commonly known as "refrigerant" is not enough).

Generally speaking, when the ambient temperature is about 35 degrees Celsius, 1, low pressure and high pressure 3, stationary pressure.

This is normal, generally three to four years old air conditioner used. The air conditioner does not completely de-refrigerate, but the effect of refrigeration will also decrease. It is because the old air conditioners all use freon as a refrigerant, and it will volatilize after a long period of 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.

The second reason for poor air conditioning and refrigeration: insufficient power supply voltage.

The normal starting voltage of the air conditioner is 220V+-10%. However, 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. However, when it is above 180V, 70-80% can be started, but when it is above 160V, only a few can be started at this time.

The reason for the poor refrigeration of air conditioning is that the power of air conditioning is not enough.

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

The fourth reason for poor air conditioning refrigeration: the external ambient temperature is too high.

There is a common saying: generally speaking, when the outdoor unit is in an environment above 43°, it is difficult for most air conditioners to transfer the heat from the indoor to the outdoors at this time, which will also lead to the phenomenon of non-refrigeration.

The fifth reason for poor air conditioning refrigeration: the air conditioner is not cleaned and maintained for a long time.

If you want the air conditioner to work normally, but also to prolong the life as much as possible without affecting human health, obviously, it is impossible to ignore it as soon as you buy it and install it. If it is not cleaned for a long time, it will also affect the heat dissipation performance of the machine, resulting in the reduction of the refrigeration effect of the air conditioner. The indoor unit is related to the health of the human body, if it is not cleaned for a long time, it will also breed bacteria, pollute the air, and make people sick after long-term use.

The sixth reason for poor air conditioning refrigeration: the copper pipe connecting the indoor unit and the outdoor unit is too long.

The maximum allowable length of the connecting pipe of the air conditioner shall not exceed 8 meters for one horse, generally speaking, the maximum length of the image pipe shall not exceed 10 meters, and the maximum length of more than 2 horses shall not exceed 15 meters. The height difference between indoor and outdoor units shall not exceed 5 meters.

Xiaomi air conditioner will not be refrigerated for a few months after I bought it, what happened?

This is the quality problem of the air conditioner, please ask the after-sales service personnel to repair it.

There are six reasons why the air conditioner does not refrigerate.

1.The compressor refrigerant is insufficient. Add refrigerant.

4. If the thermostat is broken, replace the thermostat. 5. The temperature sensor is broken, replace the sensor. 6. If the compressor is broken, replace the compressor.

How to solve the problem that the refrigeration effect of air conditioning is not good.

An air conditioner is an air conditioner. It refers to the equipment that regulates and controls the temperature, wetness, flow and other parameters of the ambient air in the building or structure by manual means.

What are the reasons for the poor refrigeration effect of air conditioning How to solve the problem of poor air conditioning refrigeration The general reasons for the poor refrigeration effect of air conditioning are:1. Lack of fluoride or insufficient use of air conditioning.

Add fluoride to add. The fan speed inside and outside the air conditioner is not good. 2 .

The fan starter or fan can be replaced. There is too much dust inside and outside the air conditioner. Cleaning and maintenance are recommended.

Poor ventilation around indoor and outdoor units. It is best to clear the surrounding obstacles. Please call us for details.
