What is the reason why the fixed frequency air conditioner does not refrigerate, and what is the rea

1.First of all, check whether the air conditioner is operating normally, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit, as long as one of them is not running normally, then you have to ask the master to repair it.

2.Then check the filter of the air conditioner, if the air conditioner starts normally, but it does not emit cold air, it is likely that the filter screen is too dusty, and it is best to spray it with that special filter cleaning agent.

3.Then check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, add freon, and check whether there is a gas leak in the cold circulation system, if there is a leak, you have to make up the leak.

If there is no above problem, the air conditioner can also operate normally, then check the operation of the air conditioner fan, if the air volume of the fan is very small, then it may be that the fan motor is old, and the fan motor should be replaced with a new one.

4.If the ventilation pipe of the air conditioner is installed for a long time, it may lead to a poor effect of transferring indoor heat to the outside, so that the refrigeration is not obvious, it is best to find a better location to reinstall it, and strive to minimize the ventilation pipe.

If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, and only the air conditioner can only be cold when it comes to the air conditioner air vent, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, at this time it is best to change to an air conditioner with more horsepower.

Air conditioning is an indispensable part of modern life, air conditioning provides people with coolness, but at the same time, air conditioning is always on is also easy to cause diseases, such as "air conditioning disease", etc., need to be used with caution.

The reasons why the aircon compressor is not working are as follows:

1. The pressure of the air conditioning system is normal.

During the operation of the air conditioner, if the system pressure is abnormal, it will affect the work of the compressor. When judging whether the pressure of the air conditioning system is normal, you can use the air conditioner filling machine to check the system pressure. At this time, if the up-and-down pressure of the air conditioning system is found to be normal compared to the normal value, it can be ruled out that the air conditioning compressor is not starting because of the lack of refrigerant.

2.Insufficient refrigerant.

If the air conditioner does not have enough refrigerant, and the air conditioner runs in this state for a long time, the compressor of the air conditioner will fail. Generally speaking, the lack of air conditioning refrigerant may be caused by improper installation, and the leakage of the system is the root cause of the lack of air conditioning refrigerant. To solve this problem, it is necessary to first check out the leakage point of the air conditioner and carry out Shenye repair, and then replenish the air conditioner with refrigerant.

3.The air of the air conditioner was not purified at the time of installation.

When installing air conditioners, it is generally easy to have the air not cleaned up when moving air conditioners. When the air conditioner is not cleaned, there will be ice blockage, and the load on the compressor will increase. When the compressor is overloaded during operation, its temperature will continue to rise.

However, the refrigeration oil of the compressor is prone to deterioration in this situation and ultimately fails to serve the role of lubrication and cooling. At this time, the temperature of the air conditioning compressor will increase further, resulting in a decrease in the insulation performance in the coil, which will eventually lead to compressor damage.

4.The power connection is incorrect.

When using the air conditioner, if its power supply is not properly connected, or the plug and socket are not in good contact, and the power cord is aging, these reasons will cause the compressor to fail to start properly. Generally, the starting voltage of a fixed-frequency air conditioner is 187V, and the voltage fluctuation range should be 198-242V, while the starting voltage of an inverter air conditioner is 156V, and the voltage fluctuation range is 176-264V.

If the compressor starts but does not work, the following types of cases apply:

1. The outdoor host is dirty and the heat dissipation effect is not good, so the host can be cleaned.

2. The main engine is not dirty, it may be that the refrigeration system is blocked; Replace the capillary tube and filter.

If the compressor doesn't start, there are two possibilities:

1. The compressor is stuck, knock it a few times with a hammer, if it still can't start, only replace the compressor.

2. The compressor coil burns out, and the only way to replace the compressor is to replace it.

1.If the heat sink of the outdoor unit is too dirty, clean the heat sink.

2.When the fan speed drops, use the tap water pipe to rinse the heat sink of the outdoor unit and try it, so the fan speed drops because of the decrease in capacitance capacity or the short circuit of the motor coil.

3.If the indoor unit filter is too dirty, it will be better to clean and refrigerate it in time.

4.There are too many freons, find a professional maintenance personnel to check the pressure measurement, and then vacuum, fluoride after fluoride collection.

5.The vacuum of the refrigeration system is incomplete, the refrigerant contains water or the refrigerant is replaced by the wrong number, the refrigerant replacement should be the high grade instead of the low grade, the heat dissipation around the compression excitation machine is not good, such as just in the corner of the wall, the compressor of the air conditioner has no shade under the sun, or the indoor placement is too much or the space is too large to cause overload operation.

Hope it helps, hope, thank you!

Why don't fixed-frequency air conditioners produce your hello dear! Because science is progressing in the development era, fixed-frequency air conditioners have been basically eliminated, and people now commonly buy and use inverter air conditioners. An inverter air conditioner is an inverter built into the air conditioner.

It can grasp the start of the compressor according to the temperature situation. This significantly reduces the frequency of compressor starting. While improving the service life of Bupei air conditioner, it also greatly reduces power consumption.

The cracked disadvantage of Huai Huai has become the first choice for inverter air conditioning. Hope it helps. If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress.

Finally, I wish you good health and a good mood!

1.Frost formation due to low outdoor temperatures.

In winter, the outdoor temperature will be low, if it is too low, the air conditioner will not be able to enter the working state normally, for example, the outdoor temperature has been below minus 15 degrees, then the inverter air conditioner will stop heating, because it can no longer normalize the frost.

Solution: Find a suitable tool to clean the frost on the air conditioner.

2.The filter is too dusty.

If you don't clean the filter for a long time, it will cause too much dust to accumulate on the filter, and the air volume of the air outlet will become smaller, which will make you feel the heat, so that you think that you can't make the heat, and there is no cold air blowing out when using the air conditioner for cooling in summer.

Solution: First carefully remove the filter of the air conditioner, clean it carefully, dry it and then put it back on. If you still don't heat it, you can also ask a master to do a deep cleaning to see if it still can't heat it, deep cleaning can help reduce bacteria.

3.Lack of freon.

The cooling and heating of air conditioners mainly rely on freon, and sometimes after being used for too long, freon will run out, and it will not be able to heat (cold) at this time.

Solution: Ask a professional to add freon to the air conditioner.

4.The check valve or four-way volt valve is faulty.

If your air conditioner is a heat pump type, then the failure to produce heat may be due to the problem of the check valve or four-way valve, because these two valves will directly affect the heating (cold) effect of the air conditioner.

Solution: Let a professional come to repair or replace the check valve or four-way valve.

Hello, I am happy to answer your questions, and have found the answer for you, there may be the following reasons why Gree fixed-frequency air conditioner does not refrigerate:1There is no cleaning filter:

After the air conditioner is used for a long time, the air conditioner filter will accumulate dust and dirt, causing the air to not flow well. This will affect the cooling effect of the air conditioner, so the filter needs to be cleaned frequently. 2.

Condenser and evaporator blockage: After the air conditioner is used for a long time, the condenser and evaporator will accumulate dust-based dust and dirt, resulting in a decrease in the cooling effect. They need to be inspected and cleaned regularly.

3.Freon leakage: Freon is a refrigerant in air conditioners, and if it leaks, it will lead to a decrease in the refrigeration effect.

It is necessary to ask professional technicians to check and deal with it. 4.The outdoor ambient temperature is too high

When the air conditioner is used in a high-temperature environment, the cooling effect will decrease. If the ambient temperature outside is too high, the air conditioner may not be able to cool down effectively. If your Sleepy Gregori fixed-frequency air conditioner is not cooling, it is recommended that you first clean the filter and check the condenser and evaporator for blockage.

If these methods do not solve the problem, you can ask professional technicians to inspect and repair.

What are the reasons why Gree fixed-frequency air conditioner is not refrigerated, and the possible reasons include:1The filter screen and pipe of the outdoor unit of the air positive car are blocked, resulting in poor air circulation and affecting the refrigeration effect.

Air conditioning is one of the indispensable electrical appliances in our lives, and the role of air conditioning is especially important in summer when the temperature is high. However, many users have reported that the cooling effect of the fixed-frequency air conditioner they use is not ideal, why is this?

First of all, we need to understand how fixed-frequency air conditioners work. Fixed-frequency air conditioner is to circulate indoor hot air through the outdoor unit to cool and send it back to the room again, and to achieve the effect of cooling or heating by adjusting the indoor temperature. The reasons for poor refrigeration may be as follows:

1.The temperature is too high.

The cooling effect of an air conditioner is related to the indoor temperature. If the indoor temperature is too high, the air conditioner needs to consume more energy to lower the temperature, and the effect will be worse. Therefore, when we use air conditioners, we should try to keep the indoor temperature within the appropriate range and not turn the temperature too low.

2.Poor air circulation.

If the indoor air circulation is not smooth, the cooling effect of the air conditioner will also be affected. Therefore, when we use the air conditioner, we should keep the indoor ventilation well, and do not let furniture and other items block the passage of air circulation.

3.Improper maintenance of air conditioning.

After the air conditioner is used for a period of time, it will produce some dust and dirt, which will affect the cooling effect of the air conditioner if it is not cleaned in time. Therefore, when we use the air conditioner, we should regularly clean the air conditioner filter and outdoor unit to ensure the normal operation of the air conditioner.

4.The air conditioning was not of good quality.

Some users report that the air conditioner they use has been poor in terms of cooling effect, which may be related to the quality of the air conditioner before the date. Some low-priced air conditioners may not be of good quality, and the cooling effect is not as good as that of high-end air conditioners. Therefore, when buying an air conditioner, you should choose a product with a guaranteed brand and quality.

To sum up, there may be many reasons for the poor refrigeration effect of fixed-frequency air conditioners, and we need to start from the aspects of indoor stool clearance, air circulation, and air conditioning maintenance to ensure the normal operation of air conditioners. At the same time, when buying an air conditioner, we should choose products with guaranteed brand and quality so as not to bring unnecessary troubles to our lives.

The cooling effect of the air conditioner is directly related to the set air conditioning temperature, and if the indoor temperature is too low, the cooling effect will be worse. Too little or leakage of air conditioning refrigerant (frelinin lead) leads to insufficient working pressure of air conditioner, resulting in poor refrigeration effect of air conditioning. 1. The long-term use of the air conditioner leads to the aging of the internal valve plate of the compressor, which leads to the decrease of the power excitation rate of the compressor transmission, resulting in the poor refrigeration effect of the air conditioner; 2. The refrigeration of the air conditioner is normal, but the air conditioning filter has not been cleaned for more than half a month, and the dust clogs the filter, resulting in a decrease in the circulating air volume, that is, the cold air volume blown out is not enough, and the refrigeration effect is poor; 3. There are obstacles in the air inlet and outlet of the air conditioner, which affects the refrigeration effect of the air conditioner; 4. The room is too large, the air conditioner used is too small, and the applicable area of the air conditioner is smaller than that of the room using the air conditioner, which will also cause poor refrigeration effect; 5. There are too many people in the room, or there are other heat sources, and the heat source will have a certain impact on the cooling effect of the air conditioner; 6. The installation of air conditioning is unreasonable, the ventilation duct is too long, and the heat transfer efficiency is low, resulting in no refrigeration; 7. The insulation effect of the room is not good.

Some rooms may have a large heat loss due to the special wall structure, and the refrigeration effect of the air conditioner is not good, but the actual air conditioner is running normally; 8. The outdoor temperature is too high. Generally speaking, if the outdoor temperature exceeds 43 degrees, it is difficult for most air conditioners to transfer indoor heat to the outside, and the indoor cooling effect is naturally limited; 9. There are quality problems in the air conditioner itself. If it is a new purchase, it may be that there is a quality problem with the air conditioner itself, resulting in poor refrigeration effect.
