My air conditioner did not refrigerate well, and the people from the maintenance department did not

There are several reasons why the refrigeration effect of the system is not good;

First; If the air volume of the air outlet is small, it means that the exhaust motor is faulty. It is necessary to check the motor control and wiring for processing.

Second; If the air output is large and the cold air is not cold enough, it means that the refrigeration system lacks fluorine, resulting in a decrease in refrigeration of the system, and fluoride needs to be added.

Third: the air outlet filter and heat exchanger of the indoor unit are dirty, the cooling capacity and indoor air heat exchange are not smooth, and the filter and heat exchanger are cleaned.

The refrigeration effect of air conditioning is not good, it is not that it is not refrigerated, this kind of problem is more difficult to repair, so the people in the maintenance department are too lazy to repair.

Just find a master and add some freon.

What are the reasons why an air conditioner does not refrigerate?

One of the reasons why the air conditioner does not refrigerate: there is not enough freon (commonly known as "refrigerant" is not enough).

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 did not completely stop cooling, but the effect of cooling decreased. This is because old air conditioners use freon as a refrigerant, which will volatilize after long-term 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 why the air conditioner does not refrigerate: the power supply voltage is not enough.

The third reason why the air conditioner does not refrigerate: the power of the air conditioner is not enough.

The fourth reason why the air conditioner does not refrigerate: the external ambient temperature is too high.

There is a common saying: when the outdoor unit is in an environment above 43°, most air conditioners are difficult to transfer the heat from the indoor to the outside, resulting in no refrigeration.

The fifth reason why the air conditioner is not refrigerated: the air conditioner is not cleaned and maintained for a long time.

If you want the air conditioner to operate normally and not affect human health, but also to prolong the life as much as possible, obviously, it is impossible to leave it alone as soon as you buy it and install it. 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. The indoor unit is related to the health of the human body, and if it is not cleaned for a long time, it will breed bacteria, pollute the air, and make people sick.

Reason 6 for the air conditioner not to refrigerate: The copper pipe connecting the indoor unit and the outdoor unit is too long.

After the product is sold, you can contact the merchant or contact the manufacturer directly.

After the operator ** goods, the provision of after-sales service is joint and several responsibility, if the operator does not provide after-sales service, consumers can make complaints to protect their rights and interests. This can be solved in the following ways:

1) Negotiate a settlement with the operator;

2) Requesting mediation by consumer associations or other lawfully established mediation organizations;

3) Lodge a complaint with the relevant administrative department;

4) Submit to an arbitration institution for arbitration in accordance with the arbitration agreement reached with the operator;

5) Filing a lawsuit with the court.

1. Gree air conditioner has a small air outlet, no refrigeration or poor refrigeration effect?

Gree air conditioning maintenance technicians said that there are mainly these reasons for this phenomenon: a. The external ambient temperature is high, and there are more indoor personnel working at full load of Gree air conditioners. b. The power supply voltage is too low, which causes the Gree air conditioner to be difficult to start, and then stops or the fuse blows after starting, so it is recommended that the user install a power regulator.

c. The air outlet of the air outlet is not large if the temperature cannot be lowered in the strong cold block room, which is because the air filter has too much dust, and the filter is cleaned. d. Improper adjustment of the thermostat. e. The installation position of Gree air conditioner is not good, which will lead to uneven indoor temperature or poor refrigeration effect.

2. What should I do if Gree users complain that the power consumption of the air conditioner they purchased is inconsistent with the manual?

The after-sales service staff of Gree air conditioner replied that the power consumption is the power used to start and stop for 24 hours at a constant temperature. In the hot summer, because the air conditioner is in working condition for a long time, its power consumption is naturally larger.

3. Is it normal for users to report that Gree air conditioners will make sound after shutdown?

A: Normal. This is the sound that is made when the high and low pressures are balanced.

4. If you choose the Gree air conditioner model and the corresponding installation location:

When choosing a Gree air conditioner, users should fully consider the size of the room area, the structure of the doors and windows of the room, the orientation, the top floor, the wall and the sealing conditions and other heat dissipation conditions; Whether the outdoor unit is installed to avoid sunlight, dust, and exhaust air. In general: ordinary room:

150-170 (W sq.m.), Living room small office: 160-200 (W sq.m.), Restaurant: 220-350 (W sq.m.), Entertainment:

200-300 (W sq.m.), Top Floor: 220-280 (W sq.m.).

5. Is the shutdown of the inverter Gree air conditioner normal?

When the user uses the Gree air conditioner, the environmental insulation is very good, and the temperature of the room is very close to the set temperature, at this time, the inverter Gree air conditioner will be shut down. Because even if the inverter Gree air conditioner runs at the lowest frequency, it will produce a certain amount of cooling, but at this time there is no energy loss in the room, according to the law of conservation of energy, the Gree air conditioner will be shut down at this time.

6. The user consults the Gree air conditioner to set 17 degrees, but when the Gree air conditioner drops to 25 degrees, it will not drop again, whether the Gree air conditioner refrigeration is abnormal.

You should look for after-sales service from an air conditioner manufacturer, who is responsible for repairs. The seller is only responsible for selling, they have no maintenance technology.

You buy an air conditioner, it is impossible to repair the air conditioner, you can only find the manufacturer's after-sales service, of course, the seller is also to find, if he doesn't care, you can go to the consumer association to complain.

There will be a 400 beginning of the ** or after-sales service ** on the large brand packaging box, so that the after-sales door-to-door processing, it is really not possible to repair the master of the home appliance maintenance department near the community, generally the problem of the external machine does not start the high-pressure package, and the lack of freon is not refrigerated

Air conditioner has an after-sales service in the manual, what should the business say, simply put, it is responsible for selling, if this responsibility is not solved, it is a reputation problem, do not ask for people, just look for after-sales.

If it is within the "warranty period", you can call "after-sales service"!The merchant will not repair! Maintenance belongs to after-sales service!

There is a special maintenance station for maintenance.

The reasons why the air conditioner only blows air and does not refrigerate and the maintenance methods are as follows: too much refrigerant causes insufficient refrigeration: too much refrigerant is generally caused by excessive refrigerant filling during maintenance, because the proportion of refrigerant in the volume of the air conditioning system is required to have a certain requirement.

If the proportion is too large, it will affect its heat dissipation, that is, the more heat dissipation, the greater the cooling capacity; Conversely, if the heat dissipation is less, the cooling capacity will be small. Similarly, if too much cooling oil is added during maintenance, the heat dissipation of the refrigeration system will also decrease. Maintenance method:

Observed from the sight glass above the drying tank. If the air conditioner does not see a single bubble from the sight glass when it is running, and there are no bubbles after the compressor is stopped, it must be too much refrigerant. If there is too much pressurized cooling oil, cloudy air bubbles can be seen in the sight glasses when the air conditioning system is running normally.

Of course, 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. Causes of refrigerant deficiency due to too little refrigerant: Most of the causes of refrigerant deficiency are due to small leaks of refrigerant in the system.

If there is not enough refrigerant in the air conditioning system, the amount of refrigerant injected into the evaporator from the expansion valve must also be reduced, when the refrigerant evaporates in the evaporator. As a result, the amount of heat absorbed will decrease, and so will the cooling capacity. Inspection Method:

Insufficient refrigerant can also be observed from the sight glasses above the drying tank, if there are continuous, slow air bubbles in the sight glasses when the air conditioner is running normally, the refrigerant is insufficient. If there is a significant bubble flipping, it means that the refrigerant is seriously insufficient. If the refrigerant is insufficient, the refrigerant should be added, but it should be noted 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.

Causes of insufficient refrigerant due to too little refrigerant: The reason for insufficient refrigerant is mostly due to the small leakage of refrigerant in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant injected into the evaporator from the expansion valve must also be reduced, when the refrigerant evaporates in the evaporator.

As a result, the amount of heat absorbed will decrease, and so will the cooling capacity. Inspection method: Insufficient refrigerant can also be observed from the sight glass above the drying tank, when the air conditioner is running normally, if the vision liquid is noisy like continuous slow bubbles in the mirror, the refrigerant is insufficient.

If there is a significant bubble flipping, it means that the refrigerant is seriously insufficient. If the refrigerant is insufficient, the refrigerant should be added, but it should be noted 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 refrigeration effect of the air conditioner is not good to repair, if the refrigerant supply to Yuqing should be insufficient or leaking, leak detection, leak filling, and appropriate fluoride can be added; If the air in the air-conditioning system is not cleaned, resulting in ice blockage of the pipes, drain them first and then replace the pipes; If the air conditioner's power supply is not in good contact, or if the power supply line is aging, replace the power cord. Of course, it is also possible that the air conditioner compressor function lock-out protection device has been activated.

This answer is applicable to most brands of air conditioner models such as Gree, Meishafu, and Haier. The town is merged before.

My air conditioner is not cooling, and multiple repairs have been fruitless.

Dear, hello very happy to answer your questions, my air conditioner is not refrigerated, many repairs to no avail, A: 1Check if the power is on, and if there is electricity; 2.

Check whether the air conditioner is in the working condition of refrigeration; 3.The dirty blockage of the indoor unit (evaporator, fan blades, filter screen, etc.) can be solved after cleaning; 4.Check if the compressor is working.

Generally, the reasons for the compressor not to work are: the external closing temperature is too high or the heat dissipation is not good, and the compressor is overheated for protection. The evaporator of the external unit is too dirty, resulting in the compressor not working, please ask a professional to clean it; 5.If there is a lack of refrigerant, ask a professional to come to check; 6.

Faulty electrical components.

If the filter is too dirty, it should be cleaned up in time, if there is a problem with the compressor, it needs to be replaced with a new air conditioner, and when the air conditioner is lacking freon, it will also lead to a poor effect, which needs to be replenished in time.

Wash the filter

Now the air conditioner is equipped with a filter, it will filter the dust and harmful substances in the air, after a long time, the filter screen will be contaminated with a lot of dust and dirt, then it will affect the release of cold air in the air conditioner, will affect the refrigeration effect of the air conditioner, because the refrigeration effect of the air conditioner caused by this situation is not good, it is very easy to deal with, there is no need to find a maintenance worker at all, remove the filter after disassembling the air conditioner, clean it and then install it back to make the refrigeration effect of the air conditioner better.

Add freon

Freon is known as refrigerant or refrigerant, it is the key to refrigeration of air conditioning, if the refrigerant in the air conditioner is insufficient, it will lead to its refrigeration effect deteriorates, and it is necessary to add Freon in time, but the air conditioner is not lacking in refrigerant and does not know, you need to ask professional after-sales personnel to come to the door to test, if you find that the refrigerant freon is insufficient, you should add it in time, but the frequency conversion air conditioner and the fixed frequency air conditioner need to add different freon, which we should pay more attention to.

Compressor issues

The refrigeration effect of the air conditioner becomes worse, and it may be a problem with the compressor, because the function of the compressor will degrade during the use of the air conditioner for a long time, and many components will age, which is the refrigeration effect of the compressor will also be affected, which will make the refrigeration effect of the air conditioner worse, but the air conditioner will be used for a few years and then replace the compressor is a bit worth the loss, the best thing to do is to replace the new air conditioner.

Change the settings

Many people's air conditioning refrigeration effect is poor, not because of the problem with the air conditioning itself, but because people's settings have problems, so this is to change the correct settings, is an effective way to make the air conditioning refrigeration effect better, if the installation is an inverter air conditioner, it is best to choose it in the automatic mode in the refrigeration state, which can effectively adjust the room temperature, will make this effect better, if the poetry teacher can not come down, you can adjust the air conditioning to the enhanced mode, so that the air conditioning refrigeration effect can also be better.

Generally, it is the car film and the refrigerant two problems. Try the air conditioning pipe, I feel much better than the original. This is the temperature measured in the summer.

You can switch the cooling mode and heating mode of the air conditioner, and restart the power supply of the air conditioner to see if it can be solved, if it still cannot be solved, you should go to a professional maintenance department for maintenance.
