What should I do if the mobile air conditioner is not cooling, what should I do if the mobile air co

Mobile air conditioning. What to do if you don't refrigerate:

1.Check whether the air conditioner is running normally, including indoor units and outdoor units, as long as one of them is not running normally, it will cause the air conditioner to not refrigerate;

2.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 screen is too dusty;

3.Check the refrigerant.

is not insufficient, that is, the so-called freon.

If it is insufficient, add freon and check the cold circulation system at the same time.

Is there an air leak, if there is an air leak, you have to make up the leak.

4.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.

5.It may be that the power of the air conditioner is not enough, which is also a common problem that the air conditioner does not refrigerate.

6.If the air conditioner is not cleaned for a long time, thick dust will accumulate on the radiator of the outdoor unit and indoor unit of the air conditioner, resulting in the poor heat dissipation effect of the radiator of the air conditioner, thus causing the air conditioner to not refrigerate.

7.When the air conditioner is not refrigerated, check whether the power plug of the air conditioner is not plugged in properly, the power plug of the air conditioner is not plugged in well or the power plug is loose, which will cause the air conditioner to not operate, of course, it cannot be refrigerated.

8.The air conditioner has not been able to reach the normal voltage during operation, or the power supply voltage is not enough, and the voltage is unstable, and the air conditioner cannot be refrigerated well.

If there are no above problems and the air conditioner is working normally, then check 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 needs to be replaced with a new one.

Mobile air conditioning, it is different from the general air conditioning, very convenient, you can move to the place you need anytime and anywhere, so it is greatly convenient for our life, when cooking the heat can be placed in the kitchen, when sleeping the heat can be placed in the living room, when working, you can move to the study.

In-room air conditioning fan.

Check if the ice is enough.

The cooling of the air conditioner fan depends on evaporation, and the effect is very weak, and it cannot be compared with the air conditioner.

Wall-mounted air conditioner. Look at the wind, if the wind is still enough to rule out the fan problem, if not enough - > repair.

Check the external machine, if it rotates normally, the wind is not small, and there is no problem. Otherwise - > repairs.

Check the voltage, if it is below 200 volts, the refrigeration will weaken, below 140, no refrigeration only blowing.

Check the filter to see if it's blocked. If there is a lot of dust, clean the filter.

If it's not the above, find someone to add fluoride, that is, the refrigerant is not enough. Add 100-300 once.

Yes, the heat dissipation of the mobile air conditioner depends on water to dissipate heat, and there is a leather bucket to keep water constantly, otherwise the compressor will stop when it starts, and it will not be refrigerated. The jitter you are talking about is the action of the compressor because it is unable to dissipate heat, causing the pressure of the high pressure to continue to rise until it is protected. Adding water will solve the problem.

Mobile air conditioner encounters high temperature and does not refrigerate, it may be that the temperature is too high, resulting in the machine can not run normally, so the compressor can not be refrigerated normally, my own experience, it is recommended that you use half a bottle of mineral water to add to the drain, so that the machine can run normally after a few minutes, believe it or not.

It may be that the output power of the air conditioner is insufficient, which is also a common problem that the air conditioner does not refrigerate. There are many reasons for this, such as: using air conditioners with low output power to carry out large-scale house cooling; Although the output power of the air conditioner is matched with the total area of the house, in the whole process of applying the air conditioner, due to the lack of airtightness of the house itself and the lack of pyrogens, the air conditioner will not be enough to refrigerate.

Solution: Change the natural environment of air conditioning, improve the tightness of the house, and reduce the pyrogen in the house.

1. 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 to check the compressor of the outdoor unit, as long as one of them is not running normally, then you have to ask a professional to repair it.

2. The air filter is blocked.

Due to the long-term use of the air conditioner, there is no regular cleaning to cause the filter to be blocked, and the sediment accumulates more and more for a long time, which eventually leads to the air conditioner not being refrigerated.

3. Insufficient refrigerant for air conditioning.

The most likely thing is that the air conditioner has no refrigerant or the refrigerant is insufficient, at this time we can ask a professional to come and add refrigerant.

4. There is a problem with the power supply or voltage.

Power supply or voltage problems are more common in summer, because in the hot summer electricity consumption is relatively large, seriously exceeding the electricity load, it will lead to air conditioning is not refrigerated, there is no better way to encounter this situation, at most is to negotiate with the local property to increase the rated power of electricity, and then there is to buy a better voltage regulator.

If the refrigerant is insufficient, we need to ask professional personnel to add refrigerant, and it is best not to add it at home alone, so as to prevent the secondary damage of the mobile air conditioner from being unable to grasp the dosage.

2. There is a defrosting controller inside the mobile air conditioner, if the defrosting controller fails, it is very likely that the air conditioner will be in a defrosting operation state, and at this time, there will be a phenomenon of excessive heating and frosting of the evaporator, which will affect the effect of air conditioning refrigeration.

3. It is also possible that there is a leakage of the check valve, which needs to find a professional to check, if there is a leakage of the check valve, then it will cause the refrigeration system to become high and low pressure, and the pressure difference will drop, so that the indoor temperature will rise, and the mobile air conditioner will naturally not be refrigerated, and we need to solve this problem in time.

4. The valve string will also cause the mobile air conditioner to not refrigerate.

First of all, you have to observe whether the external machine starts up.

Clean the filter.

Observe if the voltage is too small.

Check whether the ice type of the air conditioner is missing or gone.

There are many reasons why the air conditioner does not refrigerate, such as Frion or circuit boards, or compressed air, and so on.

The air conditioner is not cooling, you first have to check if there is any refrigerant? There are also refrigerants that are not said.

Hello, I am honored to answer this question for you, there are generally the following reasons for this situation, 1: the power of the air conditioner is not enough is one of the common reasons for the air conditioner not to refrigerate, and there are many reasons for the lack of refrigeration of the household air conditioner, if you use a small power air conditioner in a large area of the room, the power of the air conditioner can not match the room area, and it may be because the room is not in a closed state, or there is a heat source in the room, which is also the reason why people often ignore. You can increase the number of air conditioners in the room, or increase the airtightness of the room.

2: Freon insufficiency. After three or four years of use, the air conditioner is easy to cause the air conditioner to not be cold due to the lack of freon, which is also a very normal phenomenon, which is generally manifested as the refrigeration effect of the air conditioner is not the same as before, and the refrigeration is not completely stopped.

The solution to this situation is very simple, you just need to add freon. 3: The power supply voltage is insufficient, it is very easy to cause the air conditioner not to refrigerate due to insufficient power supply voltage during the peak time period, and many people always think that the air conditioner is faulty, and take out the inspection and do not find any problems, when the voltage is normal, the air conditioning refrigeration function returns to normal.

When the voltage is unstable, we can only find a solution from the voltage aspect.

1. Insufficient refrigerant: insufficient refrigerant indicates that the freon reserves in the air conditioner are insufficient, so it will lead to poor refrigeration effect or failure of refrigeration mode. In view of this situation, if it is judged that it is caused by fluorine leakage, you can contact the after-sales maintenance personnel to add enough freon to the air conditioner.

2. Check valve leakage: When the check valve of the air conditioner leaks, the high and low pressure difference of the refrigeration system will begin to drop, and the temperature of the outdoor heat exchanger will begin to rise, resulting in problems in the refrigeration operation system. In this case, it is recommended to turn off the air conditioner in time and contact the after-sales maintenance personnel for maintenance.

3. Four-way valve string gas: The mobile heat pump type air conditioner runs the cooling and heating state of the air conditioner through the four-way valve. If the refrigerant involved in heat exchange is returned directly from the outlet pipe of the compressor to the return pipe at the four-way valve, the refrigerant will be reduced, and the refrigeration effect will be reduced.

4. Excessive dust accumulation in the air conditioner: If there is no habit of cleaning the air conditioner regularly, the filter screen and condenser of the air conditioner are very easy to accumulate dust, and too much dust will lead to the performance of the air conditioner to decline, and at the same time, it will also make the refrigeration effect worse. Regular cleaning of the air conditioner's filter and condenser can reduce the failure of the air conditioner due to heat dissipation and prolong the service life of the air conditioner.

The mobile air conditioner is not refrigerated, and you must charge the air conditioner with fluoride after you move the air conditioner, if you do not charge the air conditioner, the air conditioner will definitely not be refrigerated.

If the mobile air conditioner does not refrigerate, there are many reasons for this, and it is also possible that the refrigerant inside is leaking.

Replace it with a new one and solve the problem completely.

There are many reasons: 1. For example, it is a mobile air conditioner.

The power is not enough, which is also a common problem of air conditioners not cooling. 2. If the air conditioner is not cleaned for a long time, the radiator of the outdoor unit and the indoor unit of the air conditioner will accumulate dust, and the heat dissipation effect of the slippage in the air conditioner will become worse, and the air conditioner will become the first to sell without refrigeration. Solution:

1. The power of the air conditioner may not be enough, but this is a common problem that the air conditioner does not refrigerate, and there are many reasons for this situation, for example, the refrigeration of a large area of the room with a small electric air conditioner; The power of the air conditioner corresponds to the area of the room, but during the period when the air conditioner is in use, the airtightness of the room itself is insufficient, and if there are many heat sources, the air conditioner will not allow for refrigeration. 2. If the air conditioner is not cleaned for a long time, the radiator of the outdoor unit and the indoor unit of the air conditioner will accumulate dust, the heat dissipation effect of the air conditioner radiator will become worse, and the air conditioner will become unrefrigerated.

3. When the air conditioner is not refrigerated, please check whether the power plug of the air conditioner is plugged in, if the power plug of the air conditioner is not inserted or the power plug is unplugged, the air conditioner will not work, of course it cannot be refrigerated. 4. The air conditioner cannot reach the normal voltage during operation, or the power supply voltage is insufficient, and the voltage is unstable, and the air conditioner cannot be refrigerated well.

Insufficient refrigerant can be simply self-tested to identify whether the branch is leaking fluorine, if the refrigerant is insufficient, we need to contact the maintenance master to add freon.

2. The failure of the defrosting controller makes the air conditioner unable to transfer to the defrosting operation state in time, and the evaporator frost phenomenon will occur during heat pump heating, which will affect the heat exchange efficiency of air conditioning heating, resulting in insufficient heat production and even shutdown. It should be important to observe whether the defrosting temperature sensing device is misaligned, the contact is sticky or the contact is poor, the fan impeller is slippery or the air duct is blocked, and the solenoid valve or starting relay fails.

3. Check valve (also known as check valve) leakage The high and low pressure difference between the high and low pressure of the refrigeration system decreases, the temperature of the outdoor heat exchanger rises, and the heat obtained from the outside world decreases, resulting in insufficient heat production. When the pressure of the system is detected, it will be found that the pressure on the low pressure side rises, and the pressure difference between the high and low pressure decreases.

4. Four-way valve string gas Heat pump type air conditioner switches the cooling and heating state through the four-way valve. Some of the refrigerants that should be involved in heat exchange are directly returned to the return air pipe from the compressor outlet pipe at the four-way valve, resulting in a decrease in the refrigerant involved in heat exchange, and a decrease in heat exchange efficiency, resulting in insufficient heat production.

1.Check whether the air conditioner is running normally, including indoor units and outdoor units, as long as one of them is not running normally, it will cause the air conditioner to not clear the refrigeration;

2.Check the filter of the air conditioner, if the air conditioner starts normally, but it does not emit the air conditioner, it is likely that the filter is too dusty;

3.Check whether the refrigerant is insufficient, that is, the so-called freon, if it is insufficient, add freon, and check whether there is air leakage in the cold cong rolling circulation system, and if there is a gas leakage, you have to fill the leak.

There are many reasons why the air conditioner is not refrigerated, and it is best to find a professional maintenance master to check whether there is a fault in the power supply line, and whether the refrigerant is missing, whether the compressor can work normally, whether the cooling fan is working normally, etc., will affect the refrigeration of the air conditioner.

If the mobile air conditioner does not refrigerate, then it should be the reason why your air conditioner does not have enough refrigerant. So you just need to add refrigerant to refrigerate.

If the mobile air conditioner is not refrigerated, there must be a failure, so find after-sales maintenance at this time.

Mobile air conditioners do not refrigerate for the following reasons:

The first is that the pattern of the number of empty silver is wrong. Maybe you chose the fan mode, which is not a key that will cool the front.

The second scenario is that the mobile air conditioner has no refrigerant, or the chiller has leaked.
