What is the reason why Gree air conditioner is not cold enough?

Gree air conditioner. Reasons for not refrigerating: First, it may be that the power of the air conditioner is not enough.

There are many reasons for this, such as: using low-power air conditioners to cool large areas of the room; Although the power of the air conditioner matches the area of the room, in the process of using the air conditioner, the air conditioner will also be insufficient because of the lack of sealing of the room itself and the number of heat sources. Second, the refrigeration effect of the air conditioner will decline after a long period of use, and the refrigerant.

It also volatilizes during long-term use, and if the refrigerant leaks, it will also lead to insufficient refrigerant in the air conditioner. 3. If the air conditioner is not cleaned for a long time, thick dust will accumulate on the radiator of the outdoor unit and indoor unit of the air conditioner, resulting in the poor heat dissipation effect of the radiator of the air conditioner, thus causing the air conditioner not to refrigerate. If the air conditioner is not cleaned and maintained for a long time, it will also make people prone to air conditioning disease.

Fourth, the reason why Gree air conditioner does not refrigerate may also be because the outside temperature is too high. Because the outdoor unit of the air conditioner is placed in a relatively closed area or the temperature around the outdoor unit is very high, the air around the outdoor unit of the air conditioner will not circulate, and the hot air emitted by the air conditioner cannot be discharged, which will cause the air conditioner to not refrigerate. 5. The air conditioner has not been able to reach the normal voltage in the process of operation, or the power supply of the power supply is not enough, and the voltage is unstable, and the air conditioner cannot be refrigerated well.

Extended Data Workaround:

Change the use environment of the air conditioner, increase the airtightness of the room, and reduce the heat source in the room. If the refrigerant in the air conditioner is not enough, enough refrigerant needs to be added.

Refrigerant is a tool used to provide air conditioning and cooling. If the refrigerant leakage of the air conditioner is repaired by welding in time, the refrigerant of the air conditioner should be replenished. Regularly maintain and clean the outdoor unit and indoor unit of the air conditioner to remove the dust of the radiator and improve the heat dissipation effect of the radiator.

Increase the air circulation of the outdoor unit of the air conditioner, and install the outdoor unit of the air conditioner in an open space, so that the heat emitted by the air conditioner can be discharged in time. Stagger the peak hours of electricity consumption to avoid insufficient power supply that causes the air conditioner to fail to cool. Buy a voltage regulator.

Ensure the stability of the air conditioner voltage.

There are several main reasons for this.

1. The temperature regulation of the air conditioner is too high. For example, 28

2. The service life of the air conditioner is long, and the refrigeration dose decreases.

3. If it is not cleaned for a long time, it affects the heat dissipation.

4. The mains voltage is unstable or low, and the air conditioner is in a protective state, not in a refrigeration state.

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. In addition, the old air conditioners all use freon as a refrigerant, which will volatilize after long-term use.

If it's not cold enough, you still need to check whether you need to add fluoride, and there may be many reasons for this.

Last night, I had a dream. When I woke up, I felt nostalgic for a long time, wondering what this was portending. It's so vivid and unforgettable. In my dream, I walked through the darkness and stepped into a forest, and saw that the fields were verdant, and the small pines and cypresses were growing in a row, tree to tree.

1. Insufficient freon causes the air conditioner to not refrigerate. 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 does not completely fail to refrigerate, it is the effect of refrigeration that decreases.

2. The air conditioner is not cleaned and maintained for a long time. 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 refrigeration effect of the air conditioner.

3. The air conditioner is not refrigerated due to insufficient power。When choosing an air conditioner, be sure to consider factors such as space height, level orientation, sealing performance, and occupant population. If the space is too large and the power of the air conditioner is too low, the cooling effect will not be obvious.

Precautions for turning on the air conditioner.

In the daily operation of the air conditioner, it is necessary to pay attention to the protection of the heat sink of the condenser and evaporator. The heat sink of the condenser and the evaporator is made of millimeter aluminum sheet sleeved into the copper tube and then expanded into the tube, which cannot withstand the collision, if the heat sink is damaged, it will affect the heat dissipation effect of the air conditioner and reduce the refrigeration efficiency.

Close 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.

Causes and treatment methods of air conditioner not cooling and poor refrigeration:

1.Insufficient refrigerant. When the refrigerant circulating in the refrigeration system is insufficient, the pressure values on both the high and low pressure sides will be lower than normal, and the bubble flow can be seen from the observation window. At this time, after checking that the air conditioner does not refrigerate the system without leakage, an appropriate amount of refrigerant should be added.

2.Too much refrigerant. If the refrigeration dose charged exceeds the normal capacity of the refrigeration system, the liquid refrigerant in the condenser will inevitably increase, thereby reducing the heat dissipation area and reducing the cooling efficiency.

The main manifestations are: the pressure value of the high and low pressure side of the system is higher than normal, touch the high-pressure pipe with your hand, feel hot and disconnect the air conditioning switch for about 45s, and still see the refrigerant flowing in a foamy state from the observation window. In this case, the appropriate amount of refrigerant needs to be discharged from the low-pressure side to bring it to the normal discharge pressure and temperature.

3.The refrigeration system is dirty. Due to the long-term operation of the compressor, impurities from mechanical wear can cause the reservoir dryer or expansion valve to clog slightly, resulting in insufficient cooling output.

The low pressure value of the system is too low, the pipes before and after the reservoir dryer have obvious temperature difference or frost at the expansion valve, and the reservoir dryer needs to be replaced or the refrigeration system needs to be cleaned.

4.Electronic control circuit failure: the electronic control computer board is also relatively easy to damage, as well as the work parts, compressor internal and external fan damage. When encountering such air conditioning non-refrigeration faults, most of them are repaired with minor faults; Major failure replacement.

It depends on how long you have bought the air conditioner, if you have used it for several years, you should pay attention to cleaning the filter and maintaining it when you start using the air conditioner every year. If it is not refrigerated, then you have to find Gree after-sales service, find someone to repair, if you just bought a new air conditioner, you can directly find Gree's after-sales service, let someone come to see the reason, it is really not good, you can take advantage of the warranty period to let them replace one.

1. The air conditioner is working normally, but the fault solution to the refrigeration effect cannot be achieved when the refrigeration order is issued is as follows: When the air conditioner cannot achieve the refrigeration effect, the main thing should be to check whether the temperature sensor circuit of the air conditioner is faulty. 

Clean the air conditioner filter, and if it is not impossible, find the merchant to talk about the situation, or exchange the goods.

It may be a problem with the refrigerant, but this is best to ask the seller. However, this should be a product issue, and the real Gree sales store will take over.

Check the following conditions: The mode setting is wrong, the temperature and wind speed are not set reasonably, please select the mode again, set the appropriate temperature and wind speed The filter screen is dirty, the air inlet and outlet of the indoor unit are blocked, and the angle of the air deflector is too small, please clean the filter, remove the obstruction of the air outlet, and adjust the angle of the air deflector The doors and windows, exhaust fans, etc. are not closed, resulting in poor room insulation effect, please close the doors and windows, exhaust fans, etc. The room area is large, the air conditioner is small, it is recommended to increase the wind speed When heating, the air conditioner electric auxiliary heating function is not turned on, and the air conditioner electric auxiliary heating function is turned on.

Gree's new air-conditioned room area of 9 square meters does not come down to the refrigeration temperature, and the refrigeration effect of Gree air-conditioning cannot be so bad.

1. If the voltage is okay, you can pay attention to whether the outdoor unit will automatically stop running and whether the compressor has been running when the machine is turned on (the remote control is set to refrigerate, the temperature is 16 degrees, and the air volume is maximum). If there is such a phenomenon, it can be reflected to the Gree after-sales service department, which directly affects the refrigeration effect, but it cannot be seen in the short-term trial operation or inspection room.

2. Installation problem: During installation, there is a serious flattening or flattening phenomenon at the bend of the connecting pipe of the indoor and outdoor machine. The installation position of the indoor unit is unreasonable (the indoor unit is too high. Installed in the dead corner of the room. The system is not completely emptied at the time of installation, and there is air in the system.

If the refrigeration difference occurs in the new machine, it is recommended to find the manufacturer directly to solve it, and if it doesn't work, you can strongly request to return the machine. There is the manufacturer's customer service ** on the warranty card, just contact directly. If you don't solve the problem, you can also complain to the consumer association, and there will be a place to speak.

Gree's after-sales service will not be too bad, negotiate the ...... first

It is repaired based on the experience and analysis of the maintenance worker.

Reasons affecting the refrigeration effect: 1. The filter screen of the indoor unit of the air conditioner is dirty, remove the filter screen and rinse it at the water pipe, 2. The condenser of the outdoor unit of the air conditioner is dirty, that is, the heat sink is dirty, and the water pipe can be pulled to the heat dissipator of the external unit to rinse when the power is off.

3. The doors and windows were not closed properly, and the air conditioners ran away.

Fourth, it may also be that the ambient temperature is particularly high, and the cooling speed of the machine is slower when the machine is just opened, and the above schemes have been dealt with, but there is still no improvement, that is, the air conditioning refrigerant is insufficient, and it is necessary to ask a professional master to add refrigerant.

For more information, please contact us.

Many people do not meet the expectations of the refrigeration effect of air conditioning at home, so they take it for granted that it is a lack of fluorine, and then spend money to hire a master to add fluoride, but the problem is not solved at all. The lack of refrigeration of the air conditioner is not necessarily due to a lack of fluorine, but may be just the following four small problems.

1. New air conditioners for three or five years do not need to be fluoridated.

Generally speaking, the air conditioner has not been moved, and it has not been repaired, and it is no problem to use it for three or five years without fluoride, and some air conditioners do not need to add fluoride for ten years, because the fluorine is sealed in the compressor pipeline of the air conditioner, as long as the compressor is not opened, the leakage is very slow.

2. If the air conditioner is not cleaned for a long time, it will affect the refrigeration.

If the air conditioner is dirty and the compressor is blocked, the refrigeration of the air conditioner will be affected, which is not conducive to health and affects the use of the air conditioner.

3. Poor indoor sealing will also affect refrigeration.

Generally speaking, when we use air conditioners, Qi Li still has to seal the doors and windows, and some people are worried that if they are not ventilated for a long time, the indoor air will become dirty. In fact, as long as you open the doors and windows halfway to let in a little air, don't open the doors and windows to blow the air conditioner.

Fourth, the air conditioner does not match the size of the room.

Some people see the logo 1P air conditioner is suitable for 11 square rooms, but the floor height of other people's homes is meters, and the floor height of your house is meters, so the refrigeration effect of Lu Zaimin is definitely not as good as other people's homes. If the floor height is high, you can buy a larger one appropriately, and the refrigeration effect is better.

<> air and light is not enough to refrigerate, but the noise can be caused by the air conditioner being used for a long time and starting slowly, a little etc. If the lack of fluoride in the air conditioner is caused by the lack of liquid, it is recommended to test the leak before adding fluoride. If the indoor temperature is relatively high, the refrigeration speed of the air conditioner is relatively slow, if there is no cool breeze, it may be caused by the air conditioner filter is too dirty, and the user can clean the air conditioner filter first.

There can be several reasons why an air conditioner doesn't have enough cooling. Here are some of the most common reasons:

1.The air conditioning unit is too small: If the cooling capacity of the air conditioner is too small, it may not be able to provide enough cooling air to the room. In general, it is advisable to choose the right air conditioning unit based on the desired cooling needs and the size of the room.

2.Aircon filters need to be cleaned or replaced: If your aircon's filter is clogged with dust and dirt, it can block the flow of air, resulting in poor refrigeration. Cleaning or replacing your aircon filter regularly can improve the efficiency of your aircon.

3.Clogged pipes: If there is a blockage or air leak in the air conditioner ducts, the air conditioner will not be able to circulate the refrigerant properly and cause poor cooling results. It is advisable to inspect and clean the air conditioning ducts regularly.

4.Compressor failure: The compressor in an air conditioner is one of the key components that produce cold air. If the compressor fails or does not run well, it will result in poor refrigeration. It is necessary to find a professional technician to carry out repairs.

5.High outdoor temperature: If the outside temperature is too high, the air conditioner will not be able to cool down effectively. In this case, it is advisable to use a sun shield or other shade to reduce the outside temperature, or to choose an air conditioner with higher cooling efficiency.

6.Improper on-hook position: Improper installation of the air conditioner may affect the circulation and efficiency of the air. The hang-up should be installed in a well-ventilated location, preferably not obscured by other items.

7.Refrigerant leakage: For example, the refrigerant mill leakage in the air conditioner will lead to a reduction in the cooling effect. It is necessary to investigate the cause of the leak and add new refrigerant.

All in all, there can be a variety of reasons why air conditioners don't cool enough. Depending on the situation, corresponding measures need to be taken to improve the cooling efficiency of the air conditioner and reduce energy consumption. If the cause cannot be determined or the air conditioner needs to be repaired, it is recommended to consult a professional technician or contact the manufacturer's customer service support.
