What are the main reasons why cabinet air conditioners are not cooling?

There are many reasons why cabinet air conditioners are not refrigerated, including the following:

1.The main reason.

First of all, check whether the air conditioner is operating normally, including the indoor unit and the outdoor unit, 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. Then check the filter of the air conditioner, if the air conditioner starts normally, but it does not emit cold air, it is likely that the filter screen is too dusty, and it is best to spray it with that special filter cleaning agent. Then check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, add freon, and check whether there is a gas leak in the cold circulation system, if there is a leak, you have to make up the leak.

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

2.Reason for installation.

If the ventilation pipe of the air conditioner is installed for a long time, it may lead to a poor effect of transferring indoor heat to the outside, so that the refrigeration is not obvious, it is best to find a better location to reinstall it, and strive to minimize the ventilation pipe. If the air conditioner is running normally, and everything else is in good condition, but the room does not feel the cold air, and only the air conditioner can only be cold when it comes to the air conditioner air vent, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, at this time it is best to change to an air conditioner with more horsepower.

3.Other reasons.

Cleaning problem Sometimes the long-term non-cleaning of the air conditioner will also lead to the refrigeration effect of the air conditioner, the air conditioner also needs to be cleaned and maintained, the air conditioner is exposed to the outdoors for a long time, it is easy to absorb dust and sundries, and if it is not cleaned for a long time, it will affect the heat dissipation performance of the machine, resulting in the refrigeration effect of the air conditioner. Indoor units are related to human health, and if they are not cleaned for a long time, bacteria will breed, 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.

4.Voltage and frequency problems The reason why the air conditioner is not refrigerated may be that the frequency of the air conditioner is not enough, generally the air conditioning area of 1 horse is within 10 square meters, and the house of 10-18 square meters should choose the air conditioner with the largest frequency, and so on. Sometimes the outside temperature is too high, which will also lead to the cooling effect of the air conditioner.

Sometimes the instability of the voltage will also bring the effect of non-refrigeration to the air conditioner, the normal starting voltage of the air conditioner is 220V, and the phase voltage in China is 220V, and the line voltage is in the power supply system 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.

If the freon is not enough (commonly known as not enough refrigerant), find a professional to check whether there is a lack of fluoride and replenish it in time.

2.If the ambient temperature is too high and the air conditioner is not cooling, there is no good solution to this situation.

3.The air conditioner is not cleaned for a long time. The cleaning of the air conditioner is an indispensable part of the maintenance of the air conditioner.

4.The steel pipe between the outdoor unit and the indoor unit is too long, so it is recommended to shorten the steel pipe length.

5.If there is a problem with the motherboard, the circuit cannot be powered, and the motherboard needs to be replaced.

6.If the air conditioner you just bought is not refrigerated, then you should consider whether there is a quality problem with the air conditioner, and it is recommended to buy a first-line brand air conditioner, and the quality and after-sales can be insured.

7.The problem of the compressor, the use of the compressor is too long, the compressor is aging, the efficiency is not enough to decline before, like the sound of the air conditioner, the vibration is relatively large, you need to consider whether the compressor problem, such problems can only find professionals for maintenance, or consider buying a new machine.

Cabinet air conditioningIt is a kind of split air conditioner, which is commonly used in homes and small offices.

Cabinet air conditioner has the advantages of high power and strong wind, and the starting point is relatively high, usually suitable for a larger area of the room, whether to buy a hanging air conditioner or a cabinet air conditioner needs to be determined according to the actual needs of the user.

If the living room area is small, you can cope with it by buying a table-mounted air conditioner, of course, if the living room area is large, it is best to buy a cabinet air conditioner to ensure a good cooling and heating effect.

The characteristics of split air conditioning are that the compressor or refrigeration equipment and the air conditioning outlet in the room are separated, and the integrated air conditioner, as the name suggests, is that the compressor part and the air outlet are connected as a whole, the indoor unit is hung on the wall is the hanging air conditioner, and the indoor unit is the floor type is the cabinet air conditioner.

Aside from the large air conditioner, small household air conditioner, cabinet machine, wall mounted machine is actually the difference in appearance and power, the advantage of this kind of split machine is that the noise source is placed outdoors, through good sound insulation measures, the indoor noise can be very small, but because the indoor unit and the outdoor unit of the pipe need to be installed and then connected, can not ensure very good sealing performance, so it is necessary to replenish the refrigerant every few years. And because of the split design, the cost is relatively high, and the installation is more troublesome.

What exactly is the reason why the air conditioner is not cooling?

The cabinet air conditioner is not refrigerated, first check whether the power supply voltage of the air conditioner is normal, secondly, check whether the filter screen and tube temperature sensor in the cabinet are too dusty, and check whether the output voltage of the computer board is normal.

The indoor unit or outdoor unit is not running First of all, check whether the Chigo air conditioner is operating normally, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit.

Blockage of the air filter Due to the long-term use of the air conditioner, the lack of regular pine cleaning causes the blockage of the filter screen, and the sediment accumulates more and more over the long time, which eventually leads to the air conditioner not being refrigerated.

Insufficient refrigerant in the air conditioner The most likely thing is that the air conditioner has no refrigerant or insufficient refrigerant.

There is a problem with the power supply or voltage.

If the air conditioner is not cooled, there may be obstacles in front of the outdoor unit, which will affect the normal operation of the air conditioner. Clean up or install air conditioning in open areas where there are no obstructions. The doors and windows of the room were not closed, and the interior was not sealed.

Do not open and close doors and windows frequently, and keep the air-conditioned room closed. Strong sunlight shines in or on the air conditioner. It is advisable to put curtains in the room and close them when the sun is shining.

The uncooled air volume of the air conditioner is set at the "low wind speed" position, and the air conditioner runs at low speed. The air filter is clogged, resulting in slow cooling. Clean the filter in a timely manner.

The temperature set by the temperature adjustment switch is not suitable. Solution: Then check the filter of the air conditioner.

The air conditioner is not cooling. If the air conditioner starts normally but can't dispel the cold air, it's likely that the filter is too dusty. Spray it with that special filter cleaner to clean it.

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. If the aircon can work properly without the above problems, check how well the aircon fan is working. If the fan air volume is very small, it may be that the fan motor is old and needs to be replaced with a new one.

If the ventilation pipe of the air conditioner is installed for a long time, the effect of transferring the indoor heat to the outside may be poor, so the cooling is not obvious. Find a better location to reinstall and shorten the ventilation duct as much as possible.

The reasons and solutions for cabinet air conditioners not to refrigerate are as follows:

1. If the ventilation pipe of the air conditioner is installed for a long time, the effect of the indoor heat transfer to the outdoors will be relatively poor, so that the refrigeration is not very obvious, find a better position to reinstall, and strive to shorten the ventilation pipe.

2. If the air conditioner is running normally, and its type is all in good condition, but the room does not feel the cold air, only to the air conditioning vent to have cold air, it is likely that the horsepower of the air conditioner is too small, and the space in the room is too large, then change to a large horsepower air conditioner.

3. Cleaning problem, sometimes the long-term non-cleaning of the air conditioner will also lead to the refrigeration effect of the air conditioner, the air conditioner also needs to be cleaned and maintained, the air conditioner is exposed to the outdoors for a long time, it is easy to absorb dust and sundries, and if it is not cleaned for a long time, it will affect the heat dissipation performance of the machine, resulting in the refrigeration effect of the air conditioner.

4. Voltage and frequency problems, the reason why the air conditioner is not refrigerated may be that the air conditioning frequency is not enough, generally 1 horsepower air conditioning use area within 10 square meters, 10-18 square meters of the house to choose the largest air conditioner, and so on The larger the area, the larger the frequency of the air conditioner. Sometimes the outside temperature is too high, which will also lead to the cooling effect of the air conditioner.
