Introduction to the causes and solutions of Chigo air conditioner not cooling

1. The voltage of the power supply is not enough.

Solution: Maintain a normal supply voltage.

2. The power of the air conditioner is not enough.

Solution: Make the power space of the air conditioner and the cooling capacity required to match it.

3. The external ambient temperature is too high.

Solution: Change the environment in which the outdoor unit is used (move away from the high temperature environment or make the surrounding air of the outdoor unit more easily circulated).

4. The copper pipe between the outdoor unit and the indoor unit is too long.

Solution: Minimize the length of the copper tube between the outdoor unit and the indoor unit of the air conditioner.

5. The air conditioner is not cleaned and maintained for a long time.

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

6. Freon is not enough (commonly known as not enough refrigerant).

Solution: Supplementing freon can solve the problem of air conditioning not cooling.

For details, please call us or make an appointment for maintenance.

Freon is not enough (commonly known as "refrigerant" is not enough).

When the ambient temperature is about 35 degrees Celsius, 1, low pressure and high pressure 3, static pressure. This is a normal situation, usually in the case of an 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 can cause freon leakage and problems with the machine itself.

Do not wash and maintain for a long time.

If you want the air conditioner to operate normally and not affect human health, but also to prolong the life as much as possible, obviously, it is impossible to leave it alone as soon as you buy it and install it. Because the outdoor unit is exposed to the outdoors, it is easy to absorb dust and debris, and if it is not cleaned for a long time, it will affect the heat dissipation performance of the machine, resulting in the reduction of the cooling effect of the air conditioner. The indoor unit is related to the health of the human body, and if it is not cleaned for a long time, it will breed bacteria, pollute the air, and make people sick.

The supply voltage is not enough.

The normal starting voltage of the air conditioner is 220 volts plus or minus 10%. In China's power supply system with a phase voltage of 220 volts and a line voltage of 380 volts, almost all compressors above 200 volts can be started. At 180 volts or more, 70-80 can be started, and above 160 volts, only a few can be activated.

I've done it myself. Below 160 volts it is almost impossible to start. As a rule of thumb, the compressor starting voltage is more reliable above 190 volts.

The air conditioning was not powerful enough.

The selection principle of general air conditioning is: 150-250 watts square meters for cooling, 250-350 watts for heating, in addition to comprehensive consideration of space height, level orientation, sealing performance and residential population and other factors. Any one of these factors will have a certain impact on its cooling effect.

The ambient temperature is too high.

There is a common saying: when the outdoor unit is in an environment above 43°, most air conditioners are difficult to transfer the heat from the indoor to the outside, resulting in no refrigeration.

The copper tube connecting the indoor unit and the outdoor unit is too long.

The allowable length of the connecting pipe of the air conditioner shall not exceed 8 meters for one horse, 10 meters for horses, and 15 meters for more than 2 horses. The height difference between indoor and outdoor units shall not exceed 5 meters.

Reasons and solutions for Chigo air conditioning not refrigerating:

1. There is not enough freon (also known as "refrigerant" is not enough).

This is a normal situation, generally appears in the use of three to four years of old air conditioners, air conditioning is not completely not refrigerated, but the effect of refrigeration is not good enough, this is because the old air conditioners are used as freon refrigerant, long-term use will volatilize, in addition to improper installation caused by freon leakage and the machine itself problems.

Solution, adding refrigerant can solve the problem of air conditioning not cooling.

2. The voltage of the power supply is not enough.

The power supply voltage is unstable, and it often fails to reach the normal voltage, especially during the peak of electricity consumption. Of course, this kind of problem is obviously not something that a skilled air conditioner maintenance master can solve, and we must start from the aspect of providing a stable voltage to solve the problem.

The solution is to maintain the normal supply voltage.

3. The power of the air conditioner is not enough.

This is also one of the common reasons for not refrigerating, but there are many reasons for this kind of non-refrigeration, such as small power air conditioning pipes and large area of the room, and some although the air conditioning power and the room area seem to match, but because the room is relatively unsealed (such as doors and windows are wide open, etc.) or there is a heat source in the room (such as a lot of computers), of course, the glass room is also one of the heat sources, etc.

The solution is to match the refrigeration capacity required by the power space of the air conditioner; change the conditions of the environment in which it will be used; increase the tightness of the jujube in the use environment; Reduce the heating source in the environment where the air conditioner is used to solve the problem of non-cooling.

4. The external environment temperature is too high.

This kind of non-refrigeration situation is common in our outdoor unit 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 refrigerated; There is also a common saying that when the outdoor temperature exceeds 43 degrees, it is difficult for most air conditioners to transfer indoor heat to the outside through the radiator of the outdoor unit, which will also cause the air conditioner to not refrigerate.

The solution is to change the environment in which the outdoor unit is used (move away from the high temperature environment or make the surrounding air of the outdoor unit more easily circulated).

5. 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, the radiator will absorb a lot of dust, garbage and other dirt, so that the heat dissipation effect of the radiator is poor and the air conditioner is not refrigerated; In addition, ignoring the maintenance of the air conditioner for a long time will make the room air unhygienic, more susceptible to air conditioning diseases, increase power consumption, and shorten the service life of the air conditioner.

The solution is to clean and maintain the air conditioner to make it easier to dissipate heat from a clean outdoor unit.

Summary. Hello. It's time to add refrigeration.

Not enough freon (also known as "refrigerant" is not enough) - refrigerant can solve the problem of air conditioning not cooling. Insufficient supply voltage – Maintain a normal supply voltage. The power of the air conditioner is not enough - the power of the air conditioner and the cooling capacity required by the space should be matched; change the conditions of the environment in which it will be used; Increase the airtightness of the use environment; Reduce the heating source in the environment where the air conditioner is used to solve the problem of non-cooling.

Ambient temperature is too high – change the environment in which the outdoor unit will be used (move away from the hot environment or make it easier for the air around the outdoor unit to circulate).

The reasons and solutions for Chigo air conditioners that do not refrigerate or heat.

Hello. If you want to add snow and plant freon, it is not enough (also known as "snow seed" is not enough) - adding snow and silver can solve the problem of air conditioning not cooling. Insufficient supply voltage – Maintain a normal supply voltage.

The power of the air conditioner is not enough - the power of the air conditioner and the cooling capacity required by the space should be matched; change the conditions of the environment in which it will be used; Increase the airtightness of the use environment; Reduce the use of air conditioning in the environment, such as heating, hail and the first source, etc., to solve the problem of non-cooling. Ambient ambient temperature is too high—Change the source environment in which the outdoor unit is used (move away from the hot environment or make it easier for the air around the outdoor unit to circulate).

There is no shortage of refrigerants! You turn on the air conditioner and switch modes with the remote control. Switch to refrigeration. After three minutes, if you are still sleepy and you don't hear the sound of the dust of the external machine, it is a malfunction of the computer motherboard of the external machine.

The compressor is working fine.

If the compressor is normal, it is due to the following reasons: 1. Lack of refrigerant; 2. The air conditioner flap is damaged; 3. The condenser is too dirty; 4. The slag-saving vertical flow valve or expansion valve is damaged; 5. The belt is aging too loose and the beam hall is too loose; 6. There is water in the pipeline, etc.

You try the remote control again, adjust the mode, if it still doesn't work, this situation can only be sent to the home appliance repair shop.
