The air conditioner is adjusted to refrigerate, and it doesn t blow after a while, and it has no eff

There are several reasons for this problem:

This phenomenon will be caused by a faulty part of the air conditioner's pipe temperature sensing part;

The poor performance of the compressor will cause this phenomenon (that is, the compressor is broken);

This phenomenon can also be caused by the obstruction of the refrigeration lines, especially for "capillary" filters.

Also Is the radiator of the outdoor unit dirty? Is the outdoor unit installed in a place where there is a western sun?

Is the indoor unit and the outdoor unit too far away, and the connecting pipe is too long?

If there is one of the above situations, it is easy to cause the cooling effect to be okay in the morning, evening or when the temperature is not too high, and at noon or when the temperature is high, the cooling effect will decline and become bad.

Air conditioning cooling blowing hot air troubleshooting method:

1. First of all, check whether it is the refrigeration mode, if so, check down;

2. Confirm whether the air conditioner is a heating and cooling machine, if so, see if there is a problem with the four-way valve and engage in the refrigeration situation.

3. If the air conditioner is a single chiller, it is impossible to produce hot air, and the worst is to blow the wind at room temperature.

4. There is another situation that is more dangerous, that is, the heating pipe in the refrigeration and heating machine also works in the case of refrigeration, if this situation occurs, it should be eliminated as soon as possible, otherwise it is very dangerous.

1. The air conditioner can be refrigerated for a while and will not be refrigerated for a while, which is mostly because the indoor and outdoor units are too dirty, resulting in the overheating protection of the outdoor compressor, resulting in the air conditioner being unable to continue refrigeration, and the phenomenon that the refrigeration can be turned on and refrigerated for a while is formed.

2. The reason why the air conditioner can be cooled after a while may not be cooled may be caused by the slow speed of the outdoor fan. The indoor unit filter should be cleaned first, and then the outdoor unit finned aluminum foil heat sink should be cleaned, which can be directly rinsed up and down with a tap water pipe.

3. If the fan speed is too slow, it is mostly caused by poor motor lubrication, reduced starting capacity, or short circuit between turns of the coil. The fault phenomenon that the air conditioner can be cooled after a while is not cooled is caused by the failure of the air conditioner outdoor unit, and it is necessary to engage in outdoor high-altitude work, so it is recommended to find a local professional air conditioning maintenance department for on-site maintenance.

There are several situations to consider, the compressor will inevitably shut down when there is no refrigeration, and occasionally refrigeration indicates the presence of ammonia. 1. Whether the temperature sensing head of the indoor unit is moved, resulting in insensitive temperature feeling. And the refrigeration is not normal.

2. Whether the air conditioner is too dirty, resulting in the compressor protection not working. 3. Whether the computer board of the internal machine is damaged, resulting in control disorder. 4. The external capacitor is damaged.

E4 is the fault of the compressor exhaust sensing head.

Why doesn't the air conditioner refrigerate and only blows the air.

1. Ventilation problems, first of all, ensure that the indoor and outdoor units are cleaned and the ventilation is smooth, which is also the most basic condition to ensure the normal operation of the air conditioner, including the indoor filter screen and the outdoor fins are clean. It is recommended to wash it at least twice a year, depending on the usage.

2. The refrigerant leakage in the refrigeration system leads to poor refrigeration effect, thermal protection caused by the increase of exhaust temperature, etc、、。

3. The compressor, fan and its capacitor and other circuits are damaged, resulting in compressor protection or non-working.

4. The refrigeration system is blocked, resulting in poor refrigeration, compressor protection and other failures.

5. Improper installation or poor working environment, the temperature of the external unit is too high, and the external unit exceeds the normal working environment, etc

6. The power supply voltage is low or the power supply line is faulty.

There are several reasons why the air conditioner only emits air and does not refrigerate:

1. The controller does not set the refrigeration state or the set temperature is too high;

2. The power supply voltage of the air conditioner host is not enough to cause the host to fail to start;

3. If the refrigerant of the air-conditioning host is not connected to the bell during installation, resulting in light leakage, or the copper pipe pipeline is not connected well or the copper pipe is broken, of course, it is not excluded that the copper pipe of the host itself is broken, such as: the evaporator, the condenser or the pipeline connection of the unit itself;

Fourth, the compressor of the main engine of the air conditioner is burned out. For more information, please contact us.

1: If there is a problem with the power supply of the air conditioner, you only need to plug in the power supply of the air conditioner again to ensure that the air conditioner can be powered on normally.

2: At this time, the situation that the air conditioner is not cooled is not a situation that we can solve with a method, we need to start from the aspect of stabilizing the air conditioning voltage.

It may be a lack of fluoride, just find a maintenance person to add some more.

It's that simple to find someone to fix the air conditioner failure.

Why doesn't the air conditioner refrigerate and only blows the air.

1. It is not caused by air conditioning failure.

1.The air filter is clogged, causing cooling to be too slow. Clean the filter in time.

2.The temperature of the temperature adjustment switch is not appropriate.

3.There is an obstacle in front of the outdoor unit, which affects the normal operation of the air conditioner. Clean it out or install the air conditioner in an unobstructed open area.

4.The doors and windows of the room were not closed, and the interior was not closed. Do not open and close doors and windows frequently, and keep the air-conditioned room closed.

5.There is strong direct sunlight coming in, or shining on the air conditioner. It is advisable to install curtains in the room and close the curtains when the sun is shining.

6.The air volume is set at the "low wind" position, and the air conditioner runs at low speed. To achieve the cooling effect, try to increase the air volume as much as possible.

7.There are too many people in the house, resulting in too much heat and it is impossible to adjust the temperature quickly for a while. It's common sense not to have too many people in an air-conditioned room.

8.The indoor area is too large, and the cooling capacity of the air conditioner is too small to meet the actual use needs. This problem should be paid attention to when purchasing, and you must choose the right air conditioner according to the room area. For example, 1 hp air conditioner corresponds to 12 15 square meters.

9.Electric heating appliances and other heating elements are being used in the house, which causes the power of the air conditioner to be insufficient to cause the air conditioner to not cool or the cooling effect is reduced. Try not to use high-power appliances at the same time.

10.The voltage supplied is insufficient, and if the voltage is constantly unstable, it is recommended to install a voltage regulator.

Second, caused by air conditioning failure.

1.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.

Analysis of the causes of non-refrigeration and solutions:

1. Whether the air-conditioning compressor is working normally, whether the fan is started, check whether the air-conditioning compressor, the starting capacitor and the fan are damaged, and check and eliminate.

2. Whether the air conditioner radiator is dirty and blocked, resulting in the air conditioner not being able to dissipate heat in time, causing the air conditioner to suddenly not refrigerate the fault, and the air conditioner radiator should be cleaned regularly.

3. Detect whether the air-conditioning system is deficient in fluoride and add fluoride to the air-conditioner in time. Check the method, turn on the machine first, after the compressor of the air conditioner runs continuously for 30 minutes, touch the condensing louver fan behind the air conditioner with your hands, if the temperature is not cool or hot, and the compressor is still working, it is likely to be fluorine leakage and lack of fluorine.

4. Check whether the temperature sensor of the air conditioner is damaged, whether the remote control and receiver are out of order, which are all reasons for the sudden failure of the air conditioner, please check and rule it out.

If you don't have the ability to repair yourself, it's best to ask an after-sales or home appliance maintenance master to deal with it.

1. Air conditioning power supply problem.

There are many reasons why the air conditioner is not cooling, and we are checking why the air conditioner is not cooling. First of all, you need to check whether the power supply of the air conditioner is plugged in, whether the connection between the connector of the air conditioner and the power supply is not working, if the air conditioner is not connected to the power supply, of course, there will be no refrigeration.

Maintenance method: If there is a problem with the power supply of the air conditioner, you only need to plug the power supply of the air conditioner back in to ensure that the air conditioner can be energized normally.

2. The voltage of the air conditioner is unstable.

After we check the power supply of the air conditioner, we will see if the voltage of the air conditioner is unstable or insufficient. The voltage of the air conditioner is unstable and cannot reach the predetermined voltage of the air conditioner, just like people work without food, the air conditioner will work very hard, and the voltage will be unstable during the peak period of electricity consumption.

Maintenance method: At this time, the situation that the air conditioner is not refrigerated is not a situation that we can solve with a method, we need to start from the aspect of stabilizing the air conditioning voltage.

3. The refrigerant is not enough.

The reason why the air conditioner does not refrigerate is sometimes similar to the reason why the refrigerator does not refrigerate, all because the refrigerant is not enough, resulting in the air conditioner or refrigerator not cooling. Generally, the air conditioner has been used for a long time, the refrigeration effect of the air conditioner will become worse, and the refrigerant of the air conditioner will gradually volatilize with the change of time.

Maintenance method: The refrigerant of the air conditioner is not enough, as long as enough refrigerant is added for the air conditioner, the problem of the air conditioner not being refrigerated can be solved. However, if the refrigerant of the air conditioner is not enough because of the leakage of the refrigerant, we need to seal the cavity of the leaking part of the air conditioner by welding and repairing, and then add enough refrigerant to solve the problem.

There are several reasons why the air conditioner only emits air and does not refrigerate:

1. The controller does not set the refrigeration state or the set temperature is too high;

2. The power supply voltage of the air conditioner host is not enough to cause the host to fail to start;

3. If the refrigerant of the air-conditioning host is not connected to the bell during installation, resulting in light leakage, or the copper pipe pipeline is not connected well or the copper pipe is broken, of course, it is not excluded that the copper pipe of the host itself is broken, such as: the evaporator, the condenser or the pipeline connection of the unit itself;

Fourth, the compressor of the main engine of the air conditioner is burned out.

Solution: Call the unit you purchased to request repair or return. If it is a well-known brand, you can call the manufacturer.

The reasons why the air conditioner only blows the air and does not cool the air are:

1. Too much refrigerant is generally caused by excessive refrigerant filling during maintenance, because the proportion of refrigerant in the volume of the air conditioning system has certain requirements. If the proportion is too large, it will affect its heat dissipation, that is, the more heat dissipation, the greater the cooling capacity; Conversely, if the heat dissipation is less, the cooling capacity will be small. Similarly, if too much cooling oil is added during maintenance, the heat dissipation of the refrigeration system will also decrease.

2. The lack of refrigerant is due to the trace leakage of refrigerant in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant injected into the evaporator from the expansion valve must also be reduced, when the refrigerant evaporates in the evaporator. As a result, the amount of heat absorbed will decrease, and so will the cooling capacity.

3. There is a component in the refrigeration system is the drying tank (bottle), and one of its main tasks is to absorb the water in the refrigerant to prevent the refrigeration capacity from declining due to excessive water in the refrigerant. But when the desiccant in the drying tank is in a state of moisture absorption saturation, the water can no longer be filtered out, when the refrigerant passes through the throttle hole of the expansion valve, due to the decrease of pressure and temperature factors, the water in the coolant will produce freezing phenomenon in the small holes, and cause the refrigerant to flow unsmoothly, the resistance increases, or can not flow at all.

Air conditioners are also known as air conditioners.

Air conditioning is a device that processes the temperature, humidity, purity, and airflow speed of the air to meet the needs of people's production and life, and is referred to as "air conditioning".

Air conditioner is a room conditioner, which regulates temperature and humidity, and is a unit used to deal with changes in air temperature in a space area (usually closed). Its function is to adjust the parameters such as temperature, humidity, cleanliness and air flow rate of the air in the room (or enclosed space or area) to meet the requirements of human comfort or process.

First, it may be that the refrigerant leakage is insufficient (commonly known as "refrigerant" is not enough), and the refrigerant can be added.

Second, the power supply voltage is not enough, and the compressor cannot operate normally. It is recommended to install a voltage regulator.

3. The refrigeration power of air conditioning is small and the room area is too large; Room insulation is not effective. Take these factors into account when choosing an air conditioner.

Fourth, the external environment temperature is too high.

5. The air conditioner is not cleaned and maintained for a long time. Wash in a timely manner.

6. The copper pipe connecting the indoor unit and the outdoor unit is too long. Find a professional for commissioning.

1. If the air conditioner is turned on for a period of time, but it does not blow when it blows, and it will stop automatically, it may be because the air conditioner has reached the set temperature, which is a normal phenomenon and can be done without intervention. When the indoor temperature drops, the air conditioner will restart. If it hasn't started yet, we can turn up the temperature of the air conditioner a little higher.

2. It is also possible that we are using the air conditioner, and the baffle of the air conditioner is facing upwards under the heating mode, which is also normal. In addition, if the air conditioner needs to be defrosted in the heating mode, the internal unit will also have a tremor phenomenon of taking the hole core to pause at this time, and there will be no hot air coming out. However, when the defrosting is over, it will be restarted.

3. This phenomenon generally appears in the heating mode, of course, there is another reason that if a lot of electrical appliances are turned on in the home, the voltage is unstable, and it will also cause the air conditioner to stop when it blows. You need to stop other electrical appliances first, and don't use too many appliances at once.
