The air conditioner is not cool enough, the air conditioner will cool but not cool enough

You can clean the filter and radiator of the air conditioner, and you don't need to ask a maintenance person to come to your door. When you go to the supermarket, buy a bottle of air conditioner disinfectant, and spray it on the radiator yourself, which is convenient, cheap, and effective. Jia'an's brand is really good, the taste is not pungent, my family uses this.

First. It is possible that the system has added too much f. The external machine will be hot when it works for a long time.

Second. You've used all the good ones before, so why add f. Aren't you looking for trouble?

Third, what is there to wash the external machine. It's evaporation. The heat dissipation block is well ventilated, and how to wash it. If it's dirty, just rinse it with water.

Third. That's it, he's broken your air conditioning system and it's leaking.

Hello! I'm a home appliance after-sales person. I will answer your question as follows!

First, when adding refrigerant, I don't know whether the installation and maintenance workers have done a good job of air leakage test. Second, whether the filter screen of the air conditioner is cleaned. You can call back the repairman to come back and check the repair.

Hope it helps!

It may be caused by the inside of the air conditioner being too dirty, and it is recommended that you clean the air conditioner thoroughly. However, it is better not to ask the master to wash it, because it is very expensive. Oh, you can go to the supermarket to buy an air conditioner disinfectant, follow the instructions on the bottle, it's very simple, the place where you need to do it is probably no more than 10 minutes, after cleaning, the refrigeration effect should be good.

It's too hot outside, and the outdoor unit has poor heat dissipation.

The air conditioner cools but is not cool enough for the following reasons:1. Insufficient refrigerant: If the freon used in the refrigeration system is insufficient, the refrigeration effect of air conditioning will deteriorate.

2. Insufficient power supply voltage: when the power supply voltage is reduced, the cooling effect will not be obvious during the peak period of electricity consumption.

3. The radiator has not been cleaned for a long time: the heat dissipation effect of the radiator that has not been cleaned for a long time will affect the efficiency of the entire air conditioner operation, and the refrigeration effect will decrease.

Reasons why the air conditioner is not cooling and what to do if the air conditioner is not cooling.

One of the reasons why the air conditioner does not refrigerate: The air conditioner has reached its service life, the normal service life has expired, and the air conditioner is aging.

Solution: Replace it with a new one!

The second reason why the air conditioner does not refrigerate: the refrigerant is not enough, that is, the freon is not enough, and the refrigerant is not enough.

Solution: Generally, freon will be included when you buy an air conditioner, at this time, you can add it yourself, if not, it is best to find a maintenance master to help you. It is also important to note here that you should not overuse freon, which will be counterproductive.

The third reason why the air conditioner does not refrigerate: the copper pipe between the outdoor unit and the indoor unit is too long.

Solution: Try to shorten the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner.

The fourth reason why the air conditioner is not refrigerated: the air conditioner is not cleaned and maintained for a long time, resulting in no refrigeration.

Solution: Clean and maintain the air conditioner to make the clean outdoor unit more tolerant of late heat dissipation.

The fifth reason why the air conditioner does not refrigerate: the household voltage is not enough, the power supply voltage is abnormal, sometimes high and sometimes low.

Solution: Ensure that the voltage at home is stable, especially during the peak period of electricity consumption, buy a higher resistor and voltmeter to monitor the voltage situation at all times.

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

Solution: When purchasing an air conditioner, estimate the practical area, and if the funds are sufficient, you can increase the number of horses on the basis of the appropriate number of horses.

The seventh reason why the air conditioner does not refrigerate: the air conditioner does not refrigerate due to the high temperature of the outside environment.

Solution: Change the use environment of the outdoor unit and install it in a well-ventilated place as much as possible.

The poor refrigeration effect of air conditioning is a lack of fluorine, which is not entirely correct.

If the air conditioner is not cold enough, the refrigerant in it is generally gone, and the dust on the filter screen will affect the refrigeration.

Probably, there is a lack of fluoride. Find a professional and debug.

1. Keep the return air filter of the indoor unit clean and keep the ventilation around the indoor unit smooth. 2. Regularly clean the dust on the surface of the heat exchanger of the outdoor unit to keep the ventilation around the outdoor unit smooth. 3. According to the state of the air conditioning system, determine whether the refrigerant in the pipeline of the air conditioning system is sufficient, and add it appropriately.

4. Adjust the air guide strip of the air outlet of the indoor unit to the corner hail of the air outlet above the oblique front.

1. The fan blade of the fan is broken, and the air source cavity burner will be very loud. Or the air conditioner heat sink is dusty, which causes the heat dissipation of multiple heat pipes to be poor, which increases the power of the compressor and causes the vibration to increase!

2. The sound of the compressor is normal, and the vibration of the air conditioner is mostly due to the compressor problem, and the loose screws may cause the shell and the pressing machine to stick together, causing vibration and noise.

3. If the copper pipe of the air conditioner is compressed, resulting in the smooth flow of R21, it will also cause the compressor power to increase and cause violent vibration!

4. There is also a lack of freon. It will also increase the power of the compressor and increase the vibration!

insufficient freon (often referred to as "refrigerant insufficiency"); The air conditioner is not cleaned or maintained for a long time during use; The external environment temperature is too high, and the external unit is not cooled; The power supply line is damaged and the power supply voltage is insufficient; The copper tube between the outdoor unit and the indoor unit is too long. Details of the specific reasons for not refrigerating: 1. Insufficient Freon (commonly known as "insufficient refrigerant"):

It usually occurs in air conditioners that have been used for three or four years, and the effect of air circulation refrigeration is not very good, because the condition of the air conditioning system has decreased over time, because the old air conditioners use freon as a refrigerant for air conditioners, which will volatilize after long-term use. 2. The air conditioner is not cleaned and maintained for a long time: after a long time of idle and use, the filter screen, wind blades and wind wheel of the internal unit will absorb a lot of ground dust, resulting in a very low temperature of the indoor unit air outlet, but the wind is not far away, and the room circulation slows down, resulting in poor refrigeration effect.

3. The external ambient temperature is too high and the external unit is not cooled: if the temperature around the outdoor unit of the air conditioner is too high, it will cause the air conditioner to output heat in the radiator, and when the outdoor temperature generally exceeds 43 degrees, the air conditioner will not be able to send the hot air inside to the outside, resulting in the air conditioner not being refrigerated. 4. The power supply voltage is not enough

If the power supply line is damaged or closed, or during peak electricity consumption periods, the voltage will not reach the normal level, which will affect the effect of air conditioning and refrigeration. 5. The copper pipe between the outdoor unit and the indoor unit is too long: the ventilation pipe is too long, which will lead to low heat transfer efficiency and will also cause the air conditioner to not refrigerate.

<> household air conditioner is not cool enough, it may be that the refrigerant is insufficient, and freon needs to be added; It may be that the voltage is not enough, so the peak of use is staggered. It may be that the filter screen is too dirty, so it needs to be cleaned or replaced. It may also be a problem with the outdoor unit scattered heat generator, and you only need to replace the outdoor unit of the air conditioner to a place with good ventilation effect and disturb the hail balance, or it may be a compressor problem, and the air conditioner can only be replaced.

Hello Kiss is happy to answer this question for you. Reason 1, freon is not enough (commonly known as "refrigerant" is not enough) when the ambient temperature is about 35 degrees Celsius, the air conditioner has low pressure, high pressure or more, and the static pressure is the situation, which generally appears in the 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 caused by freon leakage and problems with the source tape of the machine itself.

Reason 2: The power supply voltage is not enough, and the normal starting voltage of the air conditioner is 220V+-10%. In China's power supply system with a phase voltage of 220V and a line voltage of 380V, almost all compressors above 200V can be started. At 180V or more, 70-80% can be started, and at 160V or more, only a few can be started.

Below 160V there is almost no possibility of starting. As a rule of thumb, the compressor starting voltage is more reliable above 190V. Reason 3: The general selection principle of insufficient air conditioning power is:

150-250W square meters for cooling and 250-350W square meters for heating, in addition to taking into account factors such as space height, level orientation, sealing performance and residential population.

1.First of all, check whether the air conditioner is working properly, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit. If one of them doesn't work, you'll have to get a master to fix it.

2.Then, check the air conditioner's filter. If the air conditioner starts normally, but the air conditioner can't run away, it is likely that the filter is too dusty.

It is best to spray with a filter cleaner designed specifically for doors. 3.Check for insufficient refrigerant, also known as freon.

If not enough, add freon. At the same time, check whether there is air leakage in the cold circulation system. If there is an air leak, it must be repaired.

4.If the air conditioner is working properly and there are no above problems, then check how well the air conditioner fan is working. If the fan volume is very small, it may be that the wind carrying fan motor is old and needs to be replaced with a new one.

5.If the air conditioner's ventilation duct is installed for a long time, it may be less effective at transferring heat from the room to the outside, resulting in a situation where the cooling is not obvious. It is best to find a good location to reinstall and minimize the ventilation ducts.

6.If the air conditioner is running normally, everything else is fine, but there is no air conditioner in the room, then there is only the air conditioner when it comes to the air conditioning outlet. Probably because the air conditioner horsepower is too small and the room space is too large.

At this time, it is best to change to an air conditioner with a lot of horsepower.

1. Because the temperature is not adjusted to the appropriate degree. Because the more blind the temperature, the lower it is, the better its cooling effect, so if the temperature is not low enough, then the air conditioner is not cold enough. At this time, we only need to use the remote control to lower the temperature by a few degrees.

2. It may be because the refrigerant in the air conditioner is not enough or there is a leak. If the air conditioner wants to refrigerate, its refrigerant must be sufficient, rock dust otherwise the refrigeration effect will be worse, if this is the reason, we can add refrigerant to it.

3. The outlet of the cold air is blocked. When the filter screen is stained with dust, and the outlet of the cold air of the air conditioner is blocked, the cold air cannot be blown out, and the refrigeration effect will naturally deteriorate, and we will feel cold enough. At this time, you can ask someone to help disassemble the air conditioner and then clean the filter.

1. The filter screen is dirty.

The filter screen is to prevent indoor dust from entering the inside of the air conditioner and causing damage to the internal parts. The filter screen blocked at the air outlet for a long time is covered with dust, which affects the exchange of hot and cold air, which will inevitably make the refrigeration (heat) effect poor. Open the dimples on both sides of the air conditioner, take out the filter, the air conditioner external unit will also cause poor cooling effect if the heat dissipation is not good, you can check it yourself.

If there is a foreign object blocking the air outlet, it can be removed.

2. Insufficient power.

That is, the principle of a small horse-drawn cart, the room is large and the air conditioning is small, such as the living room is nearly 40 square meters, and a hang-up machine is on the wall. No matter how good the quality of the air conditioner is, the refrigeration effect will not work. 3. The voltage is too high or too low.

Normally, the voltage of a home circuit fluctuates around 220V, but in reality it varies a lot. The voltage of some communities can reach 250V, and some in rural areas are lower than 200V. Because of the unstable voltage, the refrigeration effect of the air conditioner is not good, you can buy a stabilized power supply or buy an undervoltage protector in the electrical box.

4. Environmental factors.

For example, if the outside temperature is about 40 degrees, and the air conditioner is facing the sun, the effect is definitely not very good. It is recommended to place the air conditioner in a well-ventilated location to facilitate the heat dissipation of the air conditioner.

If the air outlet of the air conditioner becomes smaller and the air conditioning is insufficient, if this phenomenon occurs, you can follow the following methodsDetect air conditioner failures

1. Whether the air inlet hole is closed.

2. Whether the condenser coil and heat sink are clean.

3. Whether the refrigerant in the system is sufficient.

4. Whether the blower motor is working properly.

5. Whether the blower channel is blocked.

6. Whether the air inlet filter element is blocked.

7. Whether the evaporator is blocked.

1.Fluorine deficiency Freon is the refrigerant of air conditioning, generally speaking, Freon is recycled and will not be reduced, but for the kind of old air conditioner that has been used for several years, the interior will age, Freon will volatilize, and the refrigeration effect will become worse, which is a normal phenomenon. 2.

The voltage is not enough The power supply voltage is unstable, and it often fails to reach the rated voltage of the air conditioner, especially during the peak of electricity consumption. If this is often the case, a voltage regulator can be installed. 3.

The temperature of the outdoor unit is too high The outdoor unit is installed in a relatively closed space or the temperature around the outdoor unit is too high, so it is extremely easy to cause the heat emitted by the radiator to flow away due to the lack of air circulation in the small space where the outdoor unit is located, so that the air conditioner is not cooled.

Hope it helps.

It is indeed not cold enough to turn on the air conditioner after exposure to the sun, and parking in a cool and ventilated place can avoid this situation; Turning on the internal circulation mode, blowing on all upper levels, and the minimum cooling temperature are also very important!
