The biggest worry in summer is the lack of air conditioning. For modern people, a summer without air conditioning is almost equal to the death of this person. Indeed, summer can not be separated from air conditioning, the quality of air conditioning determines the happiness of summer.

The reason why air conditioners do not cool is not necessarily due to lack of fluorine. The reason for the non-cooling of air conditioning is not necessarily the lack of fluorine.

Will the air conditioner break down? Air conditioners that are useless for half a year are easy to go wrong, mainly for slow cooling or no cooling, especially for some air conditioners that have been in use for a long time. Once this happens, people's first reaction is to ask the maintenance master to add fluorine! However, the author would like to tell you that the lack of air conditioning refrigeration is not necessarily caused by the lack of fluorine. We should know that the refrigerant in the air conditioner is not consumable. If there is no installation problem at the initial stage, the air conditioner will not leak fluorine and can operate normally for at least 10 years! The idea that air conditioners need fluorine every year is a pure rumor!

Outdoor unit maintenance of air conditioner

Every summer, once the air conditioner does not cool down, many friends go to a third-party maintenance master to "add fluorine", so they are cheated for 300 to 500 yuan. It is still not cold after adding fluorine, and the maintenance master tells them that the air conditioner is aging, the motherboard is damaged and so on. And the parts need to be replaced, and then more maintenance fees will be charged. In fact, very often, if the air conditioner is not cooled, there is no need to add fluorine at all. You can do it yourself at home!

Clean the strainer and heat sink of the indoor unit

Air-conditioned room is not clean for a long time, it is easy to accumulate dust, breed bacteria, produce peculiar smell, threaten health, and lead to the decline of refrigeration performance. This is because too much dust is attached to the fins of the heat exchanger, which seriously affects the heat transfer efficiency. The performance is that the air conditioner is not cool.

Household air conditioners should be cleaned frequently.

The solution is also very simple, is to clean the air conditioner. Many friends may want to find a master again, which is totally unnecessary and can be easily done at home. In short, it is divided into three steps. First of all, lift the shell, remove the filter, put it under the faucet, wash it with a brush and dry it. Then spray the special air conditioning cleaner evenly on the fin of the heat exchanger and rest for 15 minutes. Finally, put back the filter, cover the shell, and start the machine for a period of time. Well, isn't it easy? The air conditioner after cleaning not only has high cooling efficiency, but also has no peculiar smell, the output air is clean, take care of breathing health!

Voltage instability of municipal power supply

The voltage adaptability of frequency conversion air conditioner is good.

The normal starting voltage of general air conditioners is 220V10%, and the domestic voltage standard is 220v. Almost all compressors over 200 volts can be started. However, due to some special reasons, the power supply voltage is unstable, so that the normal voltage can not be achieved, such as in the peak period of power consumption. Compared with constant speed air conditioner, frequency conversion air conditioner has stronger adaptability to voltage. This problem cannot be solved by maintenance, but the best solution is to maintain a normal supply voltage.

Do not match the correct area and quantity

The quantity and scope of application of air conditioners are compared with those of air conditioners.

This kind of situation generally appears on the new air conditioner, many friends bought a small number of air conditioners in order to be cheap, but the bedroom area is large, and the cooling capacity of the air conditioner does not match the applicable area, similar to a pony-drawn rickshaw, although the air conditioner is on. But I can't feel cool in the house. In this case, the problem of no cooling can be solved by increasing the tightness of the space environment and reducing the heat source in the space environment. However, I still suggest that the number of air conditioners should match the applicable area.

The placement of external machines is unreasonable and the air is not ventilated

Unreasonable placement of external machines leads to lack of cooling, and

The connection between the internal and external units of the air conditioner is too long, which may lead to non-cooling.

This point is easily overlooked by consumers, that is, the length of the copper tube that connects the internal and external units of the air conditioner. Generally speaking, the maximum allowable length of the air conditioning connection pipe is as follows: the maximum length of one horse cannot exceed 8 meters, the maximum length of 1.5-2 horses can not exceed 10 meters, the maximum length of more than 2 horses can not exceed 15 meters, and the height difference between indoor and outdoor units can not exceed 5 meters. Excessive connection of copper tubes will cause a certain amount of cooling consumption, thus affecting the refrigeration efficiency of the air conditioner, resulting in the air conditioner not cooling.

Every summer is the peak period of air-conditioning use, and it is also a period of frequent air-conditioning failures. Many "black-hearted" maintenance institutions deceive consumers and defraud maintenance costs with the help of people who do not know much about air conditioners, such as the so-called "fluorination" of air conditioners if they are not cold. In fact, if you know more about air conditioning, you can easily solve some problems by yourself, especially the common uncooling phenomenon of air conditioning, which can be cleaned and solved by yourself!
