The air conditioner is not very good, what s going on?

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.

2. Too little refrigerant (freon) of air conditioning (freon) or leakage, resulting in insufficient working pressure of air conditioning, resulting in poor refrigeration effect of air conditioning.

3. The long-term use of the air conditioner causes the aging of the internal valve plate of the compressor, resulting in the decrease of the transmission power of the compressor, resulting in the poor refrigeration effect of the air conditioner.

4. The refrigeration of the air conditioner 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.

5. There are too many obstacles in the air inlet and outlet of the air conditioner, which affects the refrigeration effect of the air conditioner.

6. 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.

7. 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 refrigeration effect of air conditioning.

8. The air conditioner is installed unreasonably, the ventilation pipe is too long, and the heat transfer efficiency is low, resulting in no refrigeration.

Clean it The refrigeration effect of the air conditioner is not good, not necessarily because of the lack of refrigerant, I think your air conditioner may need to be cleaned. After the air conditioner is used for a period of time, a lot of dust and bacteria will accumulate inside, which will directly affect the cooling strength of the air conditioner. You might as well go to the supermarket to buy a bottle of air conditioner disinfectant, clean the filter and radiator of the air conditioner, I have used it at home, the effect is very good, the operation is very convenient, you can definitely do it yourself.

I've not had enough lately.

An air conditioner is an air conditioner. It refers to the equipment that uses artificial means to regulate and control the temperature, humidity, flow rate and other parameters of the ambient air in the building or structure.

How do I remove dust from my aircon filter?

To check the filter of the air conditioner, if the air conditioner starts normally, but does not emit cold air, it is likely that the filter is too dusty, spray it with that special filter cleaner.

The air conditioning refrigeration was not particularly good. There are many reasons for this. For example, the filter of the air conditioner is dirty, and the dust accumulates too much, and the cool air cannot pass through. Then there is the lack of fluoride in air conditioners.

1) There is no suitable air-conditioning model, the general selection principle of air-conditioning is: refrigeration 150 180w square meters, in addition, it is necessary to comprehensively consider factors such as space height, level orientation, and residential population. If the number of air conditioners you buy is too small, the cooling effect of the air conditioner will not be good;

2) Freon is not enough, freon will gradually volatilize with the continuous use of time, and the refrigeration effect of the air conditioner will also decrease, in this case, just add some freon again;

Nowadays, the weather is getting hotter and hotter, and most people have started to use air conditioners, especially when they go to bed at night, they can sleep comfortably with the air conditioner on. After the air conditioner is used for a long time, there will be some faults, such as not refrigerating, etc. So how can the air conditioning and refrigeration be bad?

1. It may be that the fluorine is not enough, and it needs to be added in time. When the air conditioner is running, it will continue to volatilize fluorine, and if it is not installed correctly, it will also cause fluorine leakage, and the air conditioner needs to use fluorine as a refrigerant. In this case, it is sufficient to ask a professional for fluoride supplementation.

2. It may also be that the voltage is too small. Usually the voltage when the air conditioner is turned on is about 220 volts, our phase voltage is generally 220 volts, and the line voltage is 380 volts, so that basically the equipment can start normally. If the phase voltage is only 180 volts or more, some devices will not start.

Therefore, if the power supply voltage is too low, the air conditioner cannot operate normally, which will affect the cooling effect. In this case, the power supply should be checked, and if the voltage is too low, a power stabilizer can be installed.

3. If the equipment is not cleaned for a long time, it will also lead to poor refrigeration. After the equipment is used for a long time, a lot of dust and bacteria will accumulate, which will affect the heat dissipation effect and increase the energy consumption, which will affect the cooling effect. In this case, it is necessary to clean the equipment and keep the outdoor unit clean.

What should be paid attention to when using an air conditioner.

After turning on the air conditioner, the room is usually closed, and the air cannot be replaced in time, so in order to ensure personal safety, it is necessary to check whether the valve of the gas pipe is closed. In addition, when the air conditioner is on, do not use toilet water, pesticides and other items indoors, these things are volatile, will affect human health, and may cause fire if inhaled into the air conditioner.

Summer is approaching and the weather is getting hotter. But if after turning on the air conditioner the cooling effect is not good, what is going on? Is there any good way to solve it?

1. Why is the refrigeration effect of air conditioning not good?

1. One of the simplest reasons is that the air conditioner is already lacking freon, and some people have purchased the air conditioner at home for a long time, such as using it.

In five or six years, some pipes may have been aged, or there are cracks, and the internal freon will leak, especially some old-fashioned air conditioners, which use freon as a refrigerant, which will volatilize for a long time, or leak caused by improper installation, which will also lead to poor refrigeration effect of air conditioning.

2. Some people's air conditioners have not been cleaned for a long time, if there is a lot of dust and dirt in the filter, it will affect the effect of heat dissipation, which will affect the refrigeration, and after opening, it will increase energy consumption, and the expected temperature will not be reached for a long time.

3. Another reason is that in summer, especially on dog days, the outdoor temperature is too high, and it is difficult to lower the temperature when you turn on the air conditioner at home, and then you will feel that the refrigeration effect of the air conditioner is not good, because it is difficult for the air conditioner to dissipate the indoor heat.

4. Another reason is the voltage problem, the power supply voltage of the normal air conditioner is 220 volts, but if it is lower than 220 volts, it is difficult to start between 160 volts, and the compressor can not achieve a good refrigeration effect at all.

Second, how to solve the problem of poor refrigeration effect.

1. If it is because the freon is not enough, it is relatively simple to solve, and the freon can be added directly, as long as it reaches the normal range, the refrigeration effect will be effective immediately.

2. When using the air conditioner, it is necessary to clean its filter frequently, and the air conditioner should be cleaned and maintained regularly, so that the heat dissipation effect of the outdoor unit will be better.

3. If it is because the weather is relatively hot, you can change the use environment of the outdoor unit, put the outdoor unit in a cool or well-ventilated place, and do a shade treatment.

I concluded: When we find that the air conditioner is not cooling well, we need to find out what is causing it, either it is the lack of freon, or the weather outside is relatively hot, or the reason why the air conditioner is not cleaned for a long time.

Summary. Freon is not enough, this is a normal situation, the air conditioner is not completely not refrigerated, but the refrigeration effect is not good enough, this is because the old air conditioner is using Freon as a refrigerant, and it will volatilize after a long time of use, in addition, it is not excluded that improper installation causes Freon leakage and the problem of the machine itself. 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. I've done it myself.

Below 160V there is almost no possibility of starting. As a rule of thumb, the compressor starting voltage is more reliable above 190V. 3. If the air conditioner is not cleaned and maintained for a long time, because the outdoor unit is installed outdoors, after a long time of use, it will cause a lot of dust and garbage and other dirt to be adsorbed on the radiator, which will affect the heat dissipation effect, and then affect the refrigeration effect, and also increase energy consumption and many other reasons, resulting in the refrigeration effect of the air conditioner is not as good as before.

I'm sorry I don't understand, but can you elaborate on that?

Freon is not enough, this is a normal situation, the air conditioner is not completely not refrigerated, but the refrigeration effect is not good enough, this is because the old air conditioner is using Freon as a refrigerant, and it will volatilize after a long time of use, in addition, it is not excluded that improper installation causes Freon leakage and the problem of the machine itself. 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. I've done it myself. Below 160V there is almost no possibility of starting.

As a rule of thumb, the compressor starting voltage is more reliable above 190V. 3. If the air conditioner is not cleaned and maintained for a long time, because the outdoor unit is installed outdoors, after a long time of use, it will cause a lot of dust and garbage and other dirt to be adsorbed on the radiator, which will affect the heat dissipation effect, and then affect the refrigeration effect, and also increase energy consumption and many other reasons, resulting in the refrigeration effect of the air conditioner is not as good as before.

First of all, check whether the compressor is working normally, if the compressor thermal protector trips, the compressor does not work, when the heat will not be refrigerated, sometimes good and sometimes bad, the temperature of the air conditioner will not be lowered, let's understand the reasons for the thermal protection of the compressor:

1. The heat sink is too dirty, resulting in poor heat dissipation and thermal protection, it is recommended to clean the heat sink in time to make it heat dissipate normally, and it can work normally.

2. The fan speed decreases, one reason is the decrease in capacitance capacity, the other is poor motor lubrication, the third reason is the short circuit of the motor coil, and the fourth is the broken or deformed fan blades.

If the refrigeration of the compressor is not good, first check whether the indoor unit has condensate discharged, whether the heat sink of the outdoor unit is hot, and then check whether the thick pipe in the connecting pipe joint of the outdoor unit is colder than the thin pipe and whether there is condensation. If the thick pipe is not cold, it is very likely to be caused by a lack of fluorine, and it is necessary to add an appropriate amount of freon, remember not to add excessive freon, so as not to increase the load of the compressor, which is very easy to damage the compressor for a long time.

Lack of fluorine in the system pipeline, too dirty in the machine to hinder ventilation, or too slow fan speed, four-way valve string air, etc., will affect the refrigeration effect.

It is recommended to contact after-sales service or ask a professional for maintenance.

This can be due to a lack of refrigerant and a long period of uncleaned.

The most important reason for the refrigeration of the air conditioner is freon, when the air conditioning motor is started, the freon delivery function will be turned on, and the freon is not enough, so that there may be no cold, generally speaking, like the normal situation after the air conditioner is used for three or four years, some people find that the air conditioner at home is not as good as before, which is also the reason.

Sometimes the long-term non-cleaning of the air conditioner may also lead to the refrigeration effect, the air conditioner also needs to be cleaned and maintained, the air conditioner outside we know that it is exposed to the outdoors for a long time, it is easy to absorb dust and sundries, if it is not cleaned for a long time, it will also affect the heat dissipation performance of the machine, resulting in the refrigeration effect of the air conditioner. Indoor units are related to human health, if they are not cleaned for a long time, it is easy to breed bacteria to pollute the air and make people sick. If the filter of the indoor unit is not cleaned for a long time, it will also be clogged by dust, resulting in the air conditioner not being cooled.
