What is the problem and solution of air conditioning refrigeration without heating

Reasons and solutions for air conditioners not heating:

1.If the outdoor temperature is too low, the air conditioner will not work properly, and under normal circumstances, the outdoor temperature below minus 15 degrees will cause the air conditioner to not heat, because the defrosting function of the air conditioner cannot operate normally in a low temperature environment.

It is recommended to manually clean the frost of the air conditioner, but do not use hot water to melt the frost and ice, which will cause secondary damage to the machine.

2.The pressure gauge in the air conditioner is to test the pressure of the air conditioning heating system to determine whether the air conditioning pipeline is leaking, if the pressure is higher than the normal value, it means that the freon leakage causes the air conditioner not to heat.

It is recommended to ask a maintenance person to add fluoride.

3.If the filter is not cleaned in time, the dust will block the air outlet, and the hot air will not come out, and the heating effect will be worse.

When using the air conditioner frequently, it is recommended to clean the filter once every half a month, rinse with hot water or water, and do not use detergent to clean.

4.The air conditioner does not heat due to a leaking one-way valve or a faulty capillary. The check valve is used to switch the flow direction of the refrigerant in the air conditioner, and the check valve obtains heat from the outside world by increasing the resistance of the throttling element and the capillary to achieve the heating effect.

It is recommended to replace the check valve or capillary.

5.The power of the air conditioner is not strong enough, resulting in poor cooling effect. For the space with a large room area and a high ceiling, the power of the air conditioner will be relatively high, and the low power will affect the heating effect.

Air conditioning refrigeration does not heat, this is a professional problem, so you must go to the air conditioning after-sales service office for special repairs, so that they can find out the reason, and then solve it, do not repair it yourself.

It is better not to solve the problems of the township by yourself, we do not understand the structure of the air conditioner, nor do we understand the working principle of the air conditioner, and it will be easy to break the air conditioner. Professional maintenance personnel to solve the problem.

There are four main reasons why the air conditioner does not heat: the first is that the filter screen is dusty, and the solution is to clean the filter regularly; The second is that the capillary or check valve of the air conditioner is broken, and the solution is to replace the capillary or check valve with a new one; The third is that the outdoor temperature is too low, and the solution is to clean up the frost on the air conditioner; The fourth is the lack of fluoride in the air conditioner, and the solution is to add fluoride.

I just finished asking the question.

Answer: The filter will inevitably be stained with a lot of dust after being used for a long time, which can easily lead to the heat in the air conditioner being unable to be discharged in time, resulting in the air conditioner not heating. To do this, you need to clean the vents of dust and foreign objects in a timely manner, if they are not cleaned in time, the air output will be reduced and the heat will not be generated. Cleaning the filter regularly will help unclog the vents so that the air conditioner can heat properly.

The questions are cleared.

Answer: If there is a question about the capillary or check valve of the air conditioner, it is similar to the capillaries of the human body, and is mainly made of a capillary with an outer diameter of 5 mm and a water supply circuit with an outer diameter of 20 mm. The check valve is mainly due to the prevention of reverse flow of oil flow and reverse flow of air. If there is a problem with these two, the air conditioner will not be able to heat up.

Replace the capillary or check valve so that the air conditioner can heat up properly.

The low outdoor temperature will also affect the normal use of the air conditioner. Normally, if the outside temperature is too low, the indoor air conditioner will not be able to heat up, because the air conditioner will not be able to defrost in this case. Use a special appliance to clean the frost from the air conditioner, so that the heat can be used normally.

The questions are all cleaned up.

0 degrees outdoors. Answer: If the doors and windows are not closed when the air conditioner is heating, or if the cold air enters the room due to frequent entry and exit of the room, it will also affect the heating effect of the air conditioner. In addition, when the air conditioner is in use, the air outlet should not be blocked by obstacles, otherwise the heating effect will also be affected. If it is caused by the above reasons, pay attention to closing the doors and windows when using, and do not block the air outlet.

When the outside temperature drops below freezing, frost will form on the outdoor unit of the air conditioner. At this time, when the user turns on the air conditioner for heating, it takes about 8-12 minutes to "defrost", the room temperature may decrease, and the outdoor temperature is below -5 degrees, which will affect the heating effect of the air conditioner. The lower the outdoor temperature, the worse the heating effect of the air conditioner, which is caused by the external ambient temperature and cannot be effectively solved.

If all are cleaned up. It's caused by the outside temperature.

If none of the above is true, you have to call the after-sales service for maintenance.

Is it possible that your air conditioner can only be cooled. There is no heating function.

1. The outdoor temperature is too low. The outdoor temperature is too low to cause the air conditioner to not work normally, generally outdoors below zero, the inverter air conditioner can not heat normally, so it may be that the outdoor is too low, the air conditioner can not defrost, resulting in the air conditioner can not heat. The solution of air conditioning refrigeration without heating:

Use a tool to clean the frost from the outside of the air conditioner.

2. Air leakage from the four-way valve of the air conditioner. Through-valve: A hydraulic valve term that is a control valve with four ports.

The four-way valve is an indispensable part in the refrigeration equipment, its working principle is that when the solenoid valve coil is in the power-off state, the pilot slide valve moves left under the drive of the compression spring on the right side, and the high-pressure gas enters the capillary tube and enters the piston cavity at the right end, on the other hand, the gas of the piston cavity at the left end is discharged, due to the pressure difference at both ends of the piston, the piston and the main spool valve move to the left, so that the exhaust pipe is connected with the outdoor unit pipe, and the other two pipes are connected to form a refrigeration cycle. The solution to the refrigeration of the air conditioner without heating: replace the four-way valve.

3. The filter screen is dusty. The air filter of the air conditioner has accumulated too much dust, and the vents of the internal and external units are blocked by foreign objects. The function of the filter is to adsorb the dust in the air, if the dust is too much and not cleaned in time, the air circulation will be blocked, resulting in the reduction of the air outlet volume, resulting in the heat production in the machine can not be brought out by the flowing air in time, resulting in insufficient heat production.

The solution to the air conditioner's refrigeration without heating: clean the filter.

4. The reason why the air conditioner does not heat the refrigeration: the lack of fluorine in the air conditioner. The lack of fluorine in the air conditioner not only cannot refrigerate, but also causes the heating effect.

At present, most air conditioners are heat pump type or heat pump plus auxiliary electric heating type air conditioners, both of which work on the principle of using freon to absorb heat from the outside air when evaporating, if the lack of fluorine will cause the inability to absorb heat, it will not work normally. The solution to air conditioning refrigeration without heating: fluoride.

1. If the outdoor temperature is too low, the air conditioner will not work normally, if the outdoor temperature is too low, the air conditioner cannot defrost, and the air conditioner cannot heat. In this case, you should need to use a tool to clean the frost from the air conditioner.

Second, one situation is that the voltage is insufficient, and the insufficient voltage will also affect the heating effect of the air conditioner. At this time, you can buy a power regulator, which can solve the reason for the insufficient voltage of the air conditioner.

3. There is also a possibility that the air conditioner air filter has too much dust and the vent is blocked by foreign objects, and the filter screen accumulates too much dust and does not clean it in time will block the air circulation.

1. If the air conditioner does not heat up because of the low outdoor temperature, use a defrost tool to manually clean the frost accumulated in the air conditioner.

2. If the air conditioner does not heat because of the failure of the four-way valve, then replace it with a new one-way valve.

3. If the air conditioner does not heat because of the dust accumulation of the filter, it should be carefully cleaned before the arrival of winter and summer every year, cleaned once every half a month in the state of frequent use, use hot water when cleaning, and do not use cleaning supplies such as dish soap, laundry detergent, banana water, etc., otherwise it will affect the filtration effect of the filter.

4. If the air conditioner does not heat due to lack of fluoride, then it is necessary to ask professional maintenance personnel to add fluoride to the door.

5. If the air conditioner does not heat because of the check valve problem, then replace the check valve or capillary.

If the air conditioner can be cooled normally, but the heating can not be normal, it should be caused by the four-way valve of the outdoor unit not being converted normally.

Let's go to the repair department to fix this, this is not something we can do personally, we have to go to a professional master to repair it, maybe because it heats up, well, the system is broken.

The reason why the air conditioner does not heat normally may be the problem of the air conditioning setting of the car itself, or the lack of antifreeze.

The reason and solution for the normal refrigeration of air conditioner and non-heating If you buy an inverter air conditioner, he comes from LeTV more slowly, and if it is a fixed-speed air conditioner, he cools and heats faster.

Hello, air conditioning refrigeration is normal, but it is not heating, this must be a problem with the air conditioning heating system, you need to find after-sales personnel to come to the door to solve the problem, thank you.

First of all, your air conditioner can only heat if it is cold and warm, and there is also a lack of refrigerant in the air conditioner to achieve the heating effect.

If your air conditioner is smart and normal, the reason why it is not heating may be that the Angel inside is broken, so you have to clean it up on a return trip.

If the air conditioner is cooling normally, the usual reason for not heating is due to a clogged filter, you can check it.

The reason why the refrigeration is normal and does not heat may be that the hot thought is broken, and you should just change it.

The air conditioner refrigeration is normal and does not heat, it should be that the heating system is broken, and you can find after-sales maintenance.

If you don't talk about hot and cold for a long time, it may be a problem with the air conditioner, which can be used to make a return.

If you can't fix this problem yourself, you still have to find someone.

Gree air conditioner, poor heating effect.

The air conditioner refrigerates normally, and the reason for not heating may be that there is a problem with the heater wiring.

The reason why the air conditioner is not hot may be that the line inside is blocked or the line is broken.

The reason why the air conditioner does not heat normally, this problem should be his one. If there is a problem with the plumbing setup, you should go to a professional to fix it for you.

This situation may be due to the lack of fluoride in the air conditioner.

It's best to find a master who repairs air conditioners to take a look.

Add some fluoride and you should be fine.

I've been in this situation.

The reasons and solutions for air conditioners that only cool and do not heat are as follows:

1.The air conditioner filter is too dusty and the vents are clogged. Clean your aircon filter regularly.

2.Environmental factors. When the outside ambient temperature is lower than minus 5 degrees, the air conditioner can effectively heat up the air conditioner.

3.If the refrigerant is insufficient, check for leaks and add refrigerant if there is no leakage.

4.The four-way valve is leaking, and the four-way valve is replaced with a new one.

5.If the defrost controller fails, repair the defrost controller or replace it with a new one.

6.If the auxiliary electric heating function fails, check the control circuit and auxiliary heating equipment, and repair it accordingly.

As an important appliance that regulates the temperature of the home, air conditioners play an important role in our lives. If the temperature control function of the air conditioner fails, it will only cool down and not heat, which will have a certain impact on our lives. So what is the reason why the air conditioner only cools and does not heat?

What are the workarounds?

1.There is too much dust in the air filter, and the air outlet of the inner and outer unit is blocked by foreign objects, resulting in a decrease in the air outlet volume and insufficient heating capacity. It is recommended to clean the filter once every half a month, and it can return to normal after cleaning.

2.Environmental factors refer to the ambient temperature. The ambient temperature is lower than minus 5 degrees, and the air conditioner does not heat or the heating effect is poor. At this time, only regret can be heated up by other methods.

3.Insufficient refrigerant, it may be a leak in the refrigeration system, or it may simply be a lack of refrigerant. Leak testing is required, and refrigerant is added after confirming that there are no leaks.

4.When the four-way valve blows air, some of the refrigerant that should be involved in heat exchange flows back directly from the compressor outlet pipe to the return pipe at the four-way valve, resulting in less refrigerant participating in heat exchange, reducing heat exchange efficiency, and resulting in insufficient heating capacity. It is advisable to contact a professional for replacement.

5.If the defrost controller fails and the air conditioner cannot enter the defrost operation mode, the heat exchange efficiency of the air conditioner will be affected, resulting in a lack of heat. The defrost controller needs to be repaired or replaced with a new one.

6.The auxiliary electric heating function fails. When the ambient temperature is relatively low, the air conditioner will automatically turn on the auxiliary electric heating function. If this function fails, the heating effect will deteriorate. It is recommended to contact a professional maintenance personnel for repairs.
