The reasons why the air conditioner does not refrigerate are as follows:

1. Refrigerant leakage. (It is manifested that the internal and external units are working, and the compressor is also working, but it is ineffective).

2. The compressor capacitor is damaged or defective, resulting in the compressor not working. (The phenomenon is similar to the above, but the compressor does not rotate and overheats).

3. The resistance value of the temperature sensing head at room temperature changes, resulting in the air conditioner not working. (The phenomenon is the same as when the air conditioner stops at a set temperature).

4. Poor remote control or air conditioner receiver. (It is manifested as no response from the air conditioner when it is turned on, or it does not work from time to time).

5. Four-way valve (single chiller does not have this fault) or compressor high and low pressure string, air conditioning works but has no effect. (The phenomenon is the same as the first).

6. The control panel of the internal or external unit of the air conditioner is faulty, resulting in the air conditioner not being refrigerated. (Manifested as no reflection when turned on or the air conditioner is messy).

Reasons and solutions for air conditioners not cooling:

1. Freon is not enough.

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

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

Solution: Maintain a normal supply voltage. The most taboo voltage of the air conditioner is unstable, and the instant opening of the fuse will lead to failure, especially during the peak of electricity consumption.

The manifestation of this problem is: when the voltage is normal, the air conditioning and refrigeration are also normal, and when the voltage is unstable, it will affect the air conditioner when it is not refrigerated, and we must start from the aspect of providing stable voltage to solve the problem.

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 in a 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 and so on.

The solution in this case: make the power of the air conditioner and the cooling capacity required by the space want to match; 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.

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 cooled.

This requires changing the environment in which the outdoor unit is used (moving away from the high temperature environment or making the air around the outdoor unit more easily circulated), and paying attention to choosing the correct and reasonable location when installing the air conditioner.

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 air in the room unhygienic, more susceptible to air conditioning disease, increase power consumption, and shorten the service life of the air conditioner.

Therefore, it is necessary to clean and maintain the air conditioner frequently.

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

Solution: Minimize the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner. If the design is not reasonable, the ventilation pipe of the air conditioner is installed for a long time, which will lead to the poor effect of transmitting indoor heat to the outdoors, so that the refrigeration is not obvious, it is best to find a better location to reinstall, and strive to shorten the ventilation pipe to avoid noise while maintaining the best cooling effect.

In addition to the early design and installation of air conditioners, regular inspection and maintenance in the later stage is particularly important, regular inspection and maintenance can not only ensure the efficient and stable operation of household air conditioners, but also extend their service life.

What are the problems of air conditioning not refrigerating, and how to solve them?

Reason 1: The power of the air conditioner is not good.

Generally speaking, the power of the air conditioner is selected according to the size of the room, and it should be 250-350w per square meter when cooling. If a low-power air conditioner is placed in a larger room, the cooling effect is worse. In addition, if the windows of the room are open or if the room has a heat source, the air conditioner will be affected.

Solution: Try to choose an air conditioner that matches the size of the room. When turning on the air conditioner, close the doors and windows and turn off the heat source.

Reason 2: Insufficient freon.

Freon is also a type of snow. Usually, old air conditioners have been used for a long time. This is because old air conditioners use freon as a refrigerant.

This is normal and not a good air conditioner. It could be that the freon itself evaporated at some point, or it could be due to improper operation of the unit, which could cause the freon to evaporate. It could also be an issue with the air conditioner itself.

Solution: Fill with freon.

Reason 3: Insufficient voltage.

This is especially simple during peak power consumption periods, when the supply voltage is too unstable to reach normal levels. This is something that can't be handled, just to fix the voltage problem.

Workaround: Start with the voltage and stick to the normal voltage.

Reason 4: The outside temperature is too high.

Normally, when the outside temperature reaches more than 43 degrees Celsius, it is difficult for the air conditioner radiator to heat indoors. Another reason is that when the outdoor unit is in a relatively enclosed and unventilated space, the air conditioner radiator cannot dissipate heat. Would keep the air conditioner not cool.

Solution: Move the outdoor unit to an air ventilation area.

Reason 5: Don't pay attention to air conditioner cleaning.

Since the air conditioner cannot be cleaned regularly, there is too much dust in the surrounding air to form an air conditioner, and it increases the power consumption. There are also outdoor units that are installed outdoors for a long time without cleaning, and the surface of the radiator is stained with a lot of dust and dirt, so that the radiator cannot dissipate heat normally, forming an air conditioner. Didn't cool down.

First, confirm that the compressor is started. If you don't start, you need to measure the current to see if it is stalled, system protection, etc., as well as the power supply voltage, whether the voltage is insufficient, and the starting capacitor.

The press is started but not refrigerated to check the method, the above methods should be detected in order and excluded one by one:

1. The compressor strings, there is no high and low pressure at this time, or the high pressure is very low, you can use the pressure gauge to measure, you can also try it by touching the feeling, the exhaust pipe, that is, the thinner pipe of the compressor, the temperature should be about 70-110 degrees; The inhalation tube, that is, the thicker tube, has a temperature of about 15 degrees, and it should feel cooler when touched in summer;

2. Eliminate string gas, if the pressure gauge shows that the high pressure is low, it may also be that the system has less refrigerant, it is best to check the system first, supplement the refrigerant, and add some refrigeration oil when the refrigerant is less;

3. The heat exchange of the condenser is not good, you can feel the air outlet of the condenser, generally at forty or fifty degrees, and you can clearly feel the hot air; Detect whether the condenser is dirty and blocked, and whether the condenser fan is started.

4. Whether the indoor unit is blocked, only blowing air and not refrigeration. If the refrigerant evaporates unevenly in the indoor unit, the temperature of the suction side must be very low, the compressor is easy to return liquid, and it is easy to start the liquid compressor, and you can also touch the compressor block, which is generally at 20-30 degrees, a little lower than the normal temperature.

There is also a possibility that the temperature sensor of the indoor unit is out of order, because the fixed frequency machine will stop after the temperature is reached, and if the sensor is broken, the compressor will not start;

Turn on the machine to see if the compressor of the outdoor unit is started, if there is a problem of starting without refrigeration, the compressor has electricity, the capacitor problem of starting cannot be started or the compressor is broken, and the outdoor unit has no power and the main board of the internal unit is not powered

The air conditioner is not refrigerated, mainly to see if there is fluorine leakage. That's what my family is.

If it is not refrigerated, it should be freon.

Mine is to change the starting capacitor next to the compressor, 20 yuan. Poverty is only self-helping, okay!

The air conditioner is not cooling, it is windy, and it is not refrigerated if it is fluoridated.

Air conditioning does not refrigerate. The cooling fan blades do not rotate during refrigeration.

1. Clean the filter.

If the air conditioner has been used for a long time, there will be a lot of dust and bacteria in the dust cover and air outlet filter, and if it is not cleaned up in time, it will produce a lot of mold and dust, which will affect the refrigeration effect of the air conditioner. The same power consumption will also be greater. You can remove the filter inside the air conditioner for cleaning and sterilization, and then dry it and put it back on, but avoid drying it in the strong sun to avoid damaging the filter.

Generally, there will be a lot of ash layer on the air conditioner that has not been used for a long time, you can simply wipe off the ash layer on the surface with a cloth, and then treat it with air conditioning detergent, and wipe it back and forth on the aluminum heat transfer sheet of the heat sink and the surface of the coil, which can not only decontaminate and sterilize more thoroughly, but also prolong the service life of the air conditioner. Aircon cleaner is cheap.

It may also be caused by the lack of power of the air conditioner;

The air conditioner does not refrigerate, and the area may be too large, resulting in the air conditioner not being able to refrigerate;

If the air conditioner is not cooling, it is also possible that the temperature outside is too high.

Question: The air conditioner was bought last year, the room area is not large, the outside temperature is currently about 30 degrees, I adjusted it to 17 degrees, yesterday afternoon was good, I just saw the word E3, the temperature of the room has risen.

Answer: Hello, the general air conditioner shows the fault of E3** indicates the low voltage protection of the air conditioning system, and there are several reasons for this situation: 1. The air conditioner refrigerant is insufficient; 2. The air conditioner is dirty, the expansion valve is blocked, the filter is half-blocked, and the solenoid valve is faulty; 3. The refrigeration pipeline is bent and the refrigerant circulation is not smooth.

You check it out first.

1. The freon in the air conditioner is not enough, which generally occurs in the air conditioner that has been used for more than one year. The freon function in the air conditioner is refrigeration, and if the air conditioner is used for a long time, the air conditioner will lack fluorine, and the external manifestations are not refrigeration, water leakage, shutdown, etc.

2. The air conditioner receiver is bad or the battery in the air conditioner remote control is dead, but you don't find it, then you turn it on, but it strikes, or sometimes it is refrigerated and sometimes it is not refrigerated.

3. When the voltage at home is unstable, it will directly affect the work of the air conditioner.

4. There is a dust filter in the air conditioner, which is to prevent the entry of dust and protect the air conditioner. Some customers have used the air conditioner for a long time, but they don't know how to clean it and maintain it, resulting in excessive dust accumulation, affecting the heat dissipation of the air conditioner, and it is difficult to refrigerate.

5. It's obviously turned on, but it doesn't move, or you let it wind left and right, but it goes up and down. This phenomenon is generally caused by the failure of the control panel of the internal and external units of the air conditioner.

1. Check whether it is the lack of freon, and if so, add a little freon to the air conditioner immediately. However, supplementing Freon requires professional staff, so remind everyone not to do it yourself.

2. Check whether the voltage at home is stable and whether the remote control of the air conditioner has electricity, and replace the battery with a new one if there is no power. If the voltage is not stable, we have to buy a voltage regulator to stabilize the voltage.

3. Regularly clean the indoor and outdoor units of the air conditioner. It is recommended that you buy a bottle of detergent specially designed to clean the filter, which can quickly dissolve the dust on it, rinse it and dry it.

Possible reasons why the air conditioner suddenly does not cool:

1. The air conditioner is broken.

2. The air conditioner caused by power failure is not refrigerated.

3. The air conditioner automatically identifies and stops running by the thermostat.

The air conditioner is equipped with a "thermostat" that controls the indoor temperature according to the set temperature when the air conditioner is turned on. Set 27 degrees Celsius, the air conditioner has been running for a long time, and when the indoor temperature reaches 27 degrees Celsius, the air conditioner will start to rest (stop); After stopping for a while, when the indoor temperature slowly rises to 27 degrees Celsius, this "thermostat" will command the air conditioner to start working. This is how the air conditioner keeps running, stopping, running, and shutting down again to maintain the required indoor temperature.
