The air conditioning was not cold. What to do? What to do if the air conditioner is not cold

According to your description, your air conditioner should be a split machine, which is a common phenomenon of split machine, in general, there is a leakage point of refrigerant leakage in the refrigeration circuit of the air conditioner, as you said the situation is that the maintenance personnel just add the refrigerant can be kept with 2 5 months, he did not help you find the leak point, can only temporarily solve the problem, to completely solve the problem only by finding the leak point and dealing with the refrigerant. If your air conditioner has been used for more than 3 years, maintenance is more troublesome, even if you find the leakage point and deal with it well, it is not excluded that it will leak again elsewhere next year, it is recommended to replace the air conditioner with a new one, do not move frequently (especially the split machine) as long as the machine is moved, the refrigerant will leak, thereby reducing the refrigeration effect! Hope it helps!!

Whether it is an imported brand or a domestic brand of air conditioner, the principle of its refrigeration system is exactly the same, first of all, the freon you talked about has a greasy problem, this should be you thinking too much, the refrigerant announced in the news has a problem for the current use of general pian"r22"This is a kind of refrigerant, and now scientific research has shown that this refrigerant has a greater destructive effect on the atmospheric ozone layer, and now the country is vigorously promoting it to be used"r134"That is, the fluorine-free air conditioner that we usually hear about, it is used in it"134"But the cost of this refrigerant is relatively much higher than 22, and some manufacturers still insist on using 22 in order to seek benefits, so this is the situation where the news is exposed, but the two refrigerants are basically the same for us ordinary people, and the current feeling is basically the same, only environmental problems.

Then you said that you added three times, this is the master of fluoride is extremely irresponsible, thinking that it will be a matter of adding it, fluorine in the case of normal use, it will not be used up for ten or twenty years, unless there is a leak, this master is in the case of not finding the leakage, once and twice to add fluoride to you, this time if you still choose to repair, just ask the master to find the leakage, otherwise, it is also for nothing!

To add that if you want to ask the master to leak the point, the cost will definitely be twice as high as the simple fluoride filling cost! Good luck.

There's a good chance your air conditioner is going to be cleaned! If you haven't washed it for a long time, the radiator and filter are dirty, and a lot of dirty things are adsorbed, the refrigeration effect will become very poor, so it consumes electricity and is particularly unhealthy I have also encountered this situation at home, in fact, there is no problem with the air conditioner. It is recommended that you go to the supermarket to buy a bottle of home air conditioner cleaning agent, and wash the heat sink by yourself The operation is very convenient, and the bottle is written.

It can not only make the cooling effect of the air conditioner better, but also healthier And if you often turn it on in summer, remember to clean it regularly, so that the air conditioner will have a bigger air outlet and stronger refrigeration!

There are many reasons why the air conditioner is not refrigerated, there are power circuit failures, there are also circulation pipeline failures, it is very complicated, or ask the maintenance master to overhaul it.

The relocation of the air conditioner will affect the refrigeration effect, because, some masters are not very dedicated, will miss the Freon, my suggestion is to find an air conditioning master to see, (preferably Hitachi air conditioning master) not to buy a one!

The Midea air conditioner I bought was in the same situation as yours, and the warranty period was fluoridated, and after the warranty period, it was said that it was bad luck to return to the factory, and it was fooled.

It is recommended to buy it again. Keep your eyes open, the air conditioning brand is still a good point to buy Gree, it depends on your luck!

It may be that the service life of the air conditioner has reached the limit, and it can be solved by replacing the air conditioner with a new one; It may also be that the refrigerant is not enough, and the refrigeration finger beater can be added through professional maintenance personnel; It may also be that the air conditioner is not installed in place, which can shorten the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner; It may also be that the air conditioner has not been cleaned and maintained for a long time, which can be solved by cleaning the air conditioner; It may also be that the air conditioner's inner filter's filter collects too much dust, which can be solved by cleaning the inner filter. 1. If the air conditioner is used for 15 or 20 years, it means that it has reached the service life, and the air conditioner will age, and the refrigeration effect of the air conditioner will be completely unsatisfactory at this time, and a new air conditioner needs to be replaced to solve the problem. 2. The reason why the air conditioner is refrigerated is because there is freon after the air conditioner is started, the freon delivery function will play its role, and the air conditioner will have a shortage of freon after 3 or 4 years of use, and it is necessary to find a professional maintenance master to add freon.

3. Some air conditioners are unreasonably installed due to the needs of installation or Anchu, resulting in too long ventilation pipes, so that the low heat transfer efficiency will also cause the air conditioner not to refrigerate, and the air conditioner will reduce the heat transfer efficiency due to improper installation, so it needs to be reinstalled at this time to reduce the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner. 4. The air conditioner must be cleaned and maintained for a long time in order to maintain its refrigeration effect.

The air conditioner is not cold out of the solution:

1. Temperature setting. The refrigeration effect of air conditioning is directly related to the temperature of the air conditioner, if the temperature is set high when the air conditioner is turned on on on a hot day, the air conditioning refrigeration effect is not good.

Solution: It is recommended to set the temperature when cooling: 26-28 degrees Celsius.

2. The air conditioning refrigeration is normal, but the air conditioning filter has not removed the dust for more than half a month, and the dust blocks the filter, resulting in a decrease in the circulating air volume, that is, the amount of cold air blown out is not enough, and the refrigeration effect is poor.

Solution: Clean the filter, it is better to clean it once in about 15 days.

3. There are too many obstacles in the air inlet and outlet of the air conditioner, which affects the refrigeration effect of the air conditioner. The room is too large, the air conditioner used is too small, and the applicable area of the air conditioner refrigeration capacity is smaller than the area of the room where the air conditioner is used, which will also cause poor refrigeration effect. There are too many people in the room, or there are other heat sources, which will have a certain impact on the cooling effect of the air conditioner.

The air conditioner is not installed reasonably, the ventilation pipe is too long, and the heat transfer efficiency is low, resulting in no refrigeration. The insulation effect of the room is not good, and some rooms have a special wall structure and large heat loss, so they will also feel that the refrigeration effect of the air conditioner is not good, but the actual air conditioner is running normally.

Solution: 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 the foreign objects should be removed.

4. 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 outdoors, and the indoor cooling effect is naturally limited. The quality of the air conditioner itself, if it is a newly bought air conditioner, it may be that the air conditioner itself has a quality problem, resulting in a poor refrigeration effect.

Solution: 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 partition such as a curtain to reduce the area of the room. 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.

If the air conditioner is installed unreasonably, you can find an installer to reinstall and arrange. If there is a quality problem with the newly bought air conditioner itself, you can contact the merchant for replacement or repair.

5. Insufficient freon: too little or leakage of air conditioning refrigerant (freon) causes insufficient working pressure of air conditioning, resulting in poor refrigeration effect of air conditioning.

Solution: You need to contact the after-sales service of the air conditioner or professional personnel as soon as possible to add freon;

6. The power supply voltage is not enough for air conditioning: When the air conditioner is working in refrigeration, there are requirements for voltage. However, in the summer, the use of air conditioners, fans, mobile air conditioners, tower fans, etc. will be greatly increased, and the voltage may not be high, which is why there will be more power outages in high temperature days.

As long as the voltage is slightly insufficient, the refrigeration work of the air conditioner will be affected, that is, we find that the air conditioner is not cold.

Solution: You can try to reduce the use of household appliances, for example, if you turn on the air conditioner, don't turn on the tower fan, in the early morning, in the middle of the night when the temperature is not so high, turn on the fan for cooling.

The solution to the air conditioner is not cold: clean the indoor and outdoor units and filters, check whether the power cord is loose or damaged, check the air conditioner thermostat, check the indoor and outdoor fans, maintain regularly, find professionals to check and repair, etc.

1. Clean the outdoor machine and filter of indoor sleepy socks

Cleaning the indoor and outdoor units and filters of the air conditioner is the key to keeping the air conditioner working properly. Dust and dirt deposited in indoor and outdoor units and filters can affect air circulation and cooling effectiveness. Cleaning is recommended to be done regularly.

2. Check whether the power cord is loose or damaged

Eliminate the situation where the power input is unstable due to loose power cords, and check whether the power cord is damaged and the outlet is safe.

3. Check the air conditioner thermostat

If the aircon thermostat is faulty or improperly set, it will also cause the aircon to not be cold. Check that the air conditioner thermostat is set correctly and replace the parts that need to be replaced.

4. Check the indoor and outdoor fans

When the air conditioner is not cold, you should check whether the indoor and outdoor fans are working properly. If the fan fails or works poorly, it will affect air circulation.

5. Regular maintenance

Regular maintenance of an air conditioner can extend its lifespan. For example, the right amount of refrigerant is supplied to ensure that the refrigerant pressure is stable and the desired cooling effect can be achieved.

6. Find professionals for inspection and maintenance

If none of the above measures can solve the problem, it is recommended to find a professional maintenance personnel for inspection and maintenance. This can not only better solve the problem of the air conditioner not being cold, but also avoid causing other greater damage.

1. Check the filter screen, and then check the filter screen of the household air conditioner, if the home dismantles the imitation air conditioner starts normally, but it can't emit cold air, it is likely that the filter screen is too dusty, spray it with that special filter cleaning agent.

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

3. Check whether it is in normal operation, check whether the household air conditioner is operating normally, including the indoor and outdoor units, 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.

Air Conditioning Maintenance:

1. Remove the debris from the vent to ensure normal ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation grille for foreign objects. At the same time, keep the vents unobstructed.

2. Clean the surface of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, you should carefully remove the panel, scrub it with a soft rag, and use a small brush to gently scrub the heat exchanger of the internal machine, so as to achieve the purpose of removing dust and harmful accumulation of multiplying germs.

However, it should be noted that since the heat sink is a thin aluminum material, it is easy to deform after being stressed, so it should be carefully brushed.

Most car owners mistakenly think that the air conditioner will consume more fuel when it is turned on to the maximum gear, so they will try to choose to drive the air volume as little as possible. In fact, Qingnian is not, in the process of use, the air conditioner often sucks in a reputation for sleepy dust, thus forming dirt, for a long time, mildew will occur, if a small amount of wind is mainly used for a long time, it is difficult to blow out the dirt in the air conditioner, but it will affect the health.
