Why doesn t the air conditioner refrigerate heat up?

The reasons for this are:

1. During refrigeration, the external condensate is reduced or frosted, and the temperature of the air outlet of the internal machine cannot be lowered, which is a symptom of insufficient refrigerant.

2. The air-conditioning compressor burns out and is caused by the continuous use of the air-conditioner for too long, wear or quality problems of the machine itself.

3. The air conditioner has not been maintained for a long time. If the air conditioner is not cleaned and maintained for a long time, the long-term ignorance of the air conditioner maintenance will make the room air unhygienic, the air outlet will be blocked, and the cold air will not be able to be played; It is also susceptible to air conditioning disease, increased power consumption, shortening the service life of air conditioners, etc.

4. Other parts are damaged, which will also cause the air conditioner to not be refrigerated, and the vulnerable parts include capacitors, temperature sensing heads, circuit boards, etc., which need to be tested by professional technicians.

Maintenance of air conditioner:

1. Wipe the casing with a wet rag, the most noteworthy thing here is the cleaning of the ventilation air outlet, here is generally more dust, do not use too much force when wiping, due to the different materials of the panel, too much force, easy to crush the panel.

2. Cleaning of the filter screen, after opening the air conditioning case, what catches your eye is the filter screen, and the dust of the filter screen is also a lot, according to the different models, the filter screen of some air conditioners cannot be cleaned with clean water, just wipe off the dust and expose it to the sun.

3. The radiator behind the filter screen will generally ignore this part when cleaning the air conditioner, this part is in a humid state for a long time, which is easy to be contaminated with dust and is more likely to lead to the reproduction of bacteria.

The reason why the air conditioner only cools and does not heat:

1. It is related to the outdoor temperature.

Since the air conditioner needs to absorb outdoor heat when heating, once the outdoor temperature is very low, the amount of heat that the air conditioner can absorb from the outside during heating will be reduced, resulting in the air conditioner not heating. Generally speaking, if the outdoor ambient temperature is zero degrees and below, the heating effect of the air conditioner is basically not obvious, and at this time, you will feel that the air conditioning heating has no effect at all. In addition, the outdoor unit of the air conditioner is also prone to frost in the environment below zero degrees Celsius, which causes the speed of hot air to appear when the air conditioner is turned on, which further affects the heating effect of the air conditioner.

Therefore, once the outdoor temperature is lower than 0 degrees Celsius, the air conditioner basically has no heating effect, and it is not recommended that you rely on the air conditioner to heat at this time, and you can consider the stove.

2. The filter screen is too dirty.

If it is not due to the outdoor temperature, it may be that the air conditioner filter is too dirty and the air conditioner does not heat, because it has been several months from the summer air conditioner cooling to the winter air conditioner heating, and the air conditioner filter is likely to accumulate too much dust at this time. The dust on the filter screen will block the pipes of the internal and external units of the air conditioner, hindering the circulation of air, making the heat in the indoor unit unable to come out, and naturally it will not heat the room. If the heating of the air conditioner is not started because the filter is too dirty, you need to clean the air conditioner filter in time.

The cleaning methods of the air conditioner filter are: 1. First of all, you need to remove the filter. Open the front cover of the air conditioner first, and then you will see the buckles on both sides of the filter, at this time, you need to hold the filter with one hand, and lift the buckles on both sides with the other hand, you can easily remove it, but be careful not to make too much force, otherwise it may cause damage to the filter.

2. After removing the filter, it can be cleaned. Just scrub the dust stains off the filter with clean water, and if there are other stubborn dirts, it is recommended to clean them with a neutral detergent. After cleaning, the filter should be placed in a cool place to dry.

3. After the filter is dried, reinstall it according to the original dismantling method, and then cover the front cover of the air conditioner, and all the work will be completed.

Seeing that it is about to be summer, it was winter and only needed refrigeration, if the refrigeration does not work, it will not work, anyway, it will not be used, but refrigeration in summer can be necessary, so what happens when the air conditioner is not refrigerated but can be heated? How do we fix this? Come and find out more!

Air conditioner Air conditioner does not cool but can heat the first reason:

Check whether the air conditioner is connected wrong when wiring, which will lead to the situation that the air conditioner can only heat up and cannot be cooled normally, then you must ask a professional maintenance master to check and repair, do not operate it easily, if not, check whether the mode of the air conditioner has not been changed, use the remote control to change the mode to try, and adjust to the correct refrigeration mode.

The air conditioner does not cool but can heat the second reason:

If the air conditioner is used frequently and is not checked regularly, it is very likely that the internal parts of the air conditioner are faulty, check whether the solenoid valve of the air conditioner is normal, if the solenoid valve of the air conditioner is damaged, such as the problem caused by the mechanical failure of the four-way valve switch of the air conditioner, it is recommended to ask a professional master to replace it again.

The air conditioner does not cool but can heat the third reason:

Check whether the refrigerant of the air conditioner is sufficient, or the refrigerant caused by leakage is insufficient, so that the air conditioner is not refrigerated, such a situation generally appears in the air conditioner that has been used for several years, because the air conditioner needs sufficient support for refrigeration, so find a professional master to check what the refrigerant is caused by the shortage, if it is a leak, add an appropriate amount of refrigerant after maintenance.

The above are the reasons why the air conditioner does not cool but can make heat, I hope it will help you.

Not necessarily, if it is related to the four-way valve, then it is possible. It does not affect, but if there is a problem with the four-way valve or the four-way valve relay, it will not be able to heat up.

The lack of refrigeration of the air conditioner will affect the heating effect, because refrigeration and heating are opposite processes, and if there is a lack of freon, it will affect the effect of cooling or heating.

The air conditioner is not cooling, then it means that there is only heat. Then you can modulate the reason why the heat is not cooling, and you can go to the repair personnel to help you see how to repair it, because it should also be used when it is hot, it can be heated in winter, and it can be refrigerated in summer and can be used normally.

According to the problems of the air conditioner itself, it can be judged whether it can be heated.

For example, if the four-way valve is broken, it can only be heated;

Or it is a lack of fluorine, and the cooling and heating are not very good.

Of course, the compressor does not start, and it is easy to heat without refrigeration.

Of course, most of the air conditioners themselves have auxiliary heating, so there is still a little temperature in the heating state.

Can an air conditioner heat if it doesn't cool? I think that if the air conditioner is not cooled, it should be able to cool and heat, because the nature of cooling and heating is different.

Absolutely, I'm not kidding! You turn the inside and outside machines over and try it.

If the air conditioner has air conditioning or hot air, note that fluoride is present but not enough, it can eliminate compressor or electrical failure. In this case, the temperature of the exhaust pipe of the air conditioner compressor can be used at the temperature point if the ambient temperature is exceeded. One of the most likely causes is the lack of fluoride in the system.

The approximate reason why the air conditioner does not heat up.

1. There is a problem with the capillary or check valve of the air conditioner. If the air conditioner does not heat due to this reason, the capillary tube or check valve should be replaced to solve the problem of the air conditioner not heating.

2. Lack of fluorine (refrigerant) in the air conditioner. Ask a professional to add fluoride (refrigerant) to solve the problem of air conditioning not heating.

3. Air leakage from the four-way valve of the air conditioner. Replacing the four-way valve can solve the problem of air conditioning not heating.

4. There is dust on the filter screen, so that the heat production in the machine cannot be brought out by the flowing air in time, resulting in insufficient heating production. 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.

What to do if the air conditioner does not heat due to this reason: cleaning the filter screen can solve the problem of the air conditioner not heating.

5. The outdoor temperature is too low. The outdoor temperature is too low and the air conditioner will not work normally, generally the outdoor is below zero, and the outdoor of the inverter air conditioner is about minus 15 degrees Celsius can no longer heat normally, so it may be that the outdoor brother is too low, the air conditioner can not defrost, and the air conditioner cannot heat.

What to do if the air conditioner does not heat due to this reason: use a tool to clean the frost on the air conditioner to solve the problem of the air conditioner not heating.

If you don't know too much, please find a professional to fix it.

1. Improper use or maintenance of air conditioners cause air conditioners not to heat: According to experts, about eighty percent of air conditioning heating failures are not machine problems, but improper use or improper maintenance of the machine by air conditioning users. When using air conditioning for heating in winter, pay attention to the airtightness of the room, if the outdoor unit has frost and icing, do not use hot water to defrost and ice, you should stop using the air conditioner, contact the maintenance personnel for inspection and maintenance.

2. If the air conditioner does not heat up due to too much dust: if the air conditioner does not remove dust for a long time, it is easy to make the air filter screen accumulate too much dust, and the air vent inside and outside the air conditioner is blocked by foreign objects. The air conditioner should be maintained frequently and the air filter should be cleaned regularly so that the air outlet can supply air normally.

3. The lack of fluorine in the air conditioner causes the air conditioner not to heat: now most air conditioning users use heat pump type or heat pump plus auxiliary electric heating type air conditioner, the working principle of these two air conditioners is to absorb heat from the outdoor air when the freon evaporates, when the outdoor temperature is low, the temperature difference with the evaporation temperature of freon is small, the heat exchange effect becomes worse, and the hot air is less. Therefore, if it is an old model, the service life is longer, the wear of the compressor is larger, and when the outdoor temperature is below 0, the heating effect of the air conditioner is difficult to be satisfied.

In addition, if the nut at the copper pipe horn is not tightened during the installation of your own air conditioner, or the machine has been moved, it can be considered as a lack of fluorine; In addition, it is also common to have a line modification circuit control fault, for example, if the external unit is not working, it is most likely due to capacitor, temperature probe or motherboard failure. If the air conditioner is fluoride, contact the air conditioner after-sales personnel as soon as possible to solve the problem.

4. The external environment of some air conditioners is also a factor that causes air conditioners not to heat: the temperature in Dalian is relatively low in winter, if the outdoor temperature is too low, the heating effect will be significantly worse, and the actual heat production is not enough. The practical heating area of the air conditioner is smaller than the actual area of the room, which will lead to factors such as insufficient heating of the air conditioner.

Cooling control technology, by automatically sensing the outside temperature, adjust their working status at any time, to prevent users from feeling too low and causing unnecessary energy waste.

Ten minutes before the start of operation, the air deflector is supplied downward to cool the activity area of the person and cool the human body first. When the cooling sensation reaches a certain level, the air is sent upwards to cool the whole room. According to the temperature change of the air supply outlet, the upper and lower wind direction is adjusted, which not only avoids overcooling, but also prevents the air conditioning disease caused by blowing cold air for a long time, and protects human health.

Principle of somatosensory control:

The somatosensory control is mainly realized by the temperature sensing software of the remote control, and the remote control sends the temperature signal around the collected remote control to the indoor unit receiver at a fixed time, and the indoor unit adjusts the press frequency according to the feedback information of the remote control to indicate the changes in the surrounding environment.

When the air conditioner is running, because the hot air rises and the cold air falls, if you only use the sensor of the internal machine, the temperature measurement will be inaccurate, if you add a temperature measurement sensor on the remote control, and then add a human-computer dialogue function, so that when you put the remote control next to you, the remote control will send a signal to the internal machine every three minutes to more accurately control the temperature of the air conditioner.

Reasons why the air conditioner is not heating:

1. Generally speaking, the heating effect of the air conditioner is not good, partly due to too much dust accumulation in the air filter and the blockage of the air vent of the internal and external units by foreign objects.

2. Fluoride deficiency. At present, most of the air conditioners are heat pump type or heat pump type with auxiliary electric heating. The working principle of these two air conditioners is that when the freon evaporates, it absorbs heat from the outside air, and when the outdoor temperature is low, the temperature difference with the evaporation temperature of the freon is smaller, and the heat exchange effect becomes worse, and the hot air is less.

3. The fault mainly occurs in the spring quiet elimination of the four-way bend solenoid valve or its control circuit, and it may also be the AC contactor, thermostat and over-temperature fuse known for the electric heater and its power supply circuit.

Summary. Extended information 1: When using the air conditioner daily, clean the filter regularly as needed to maintain the cleanliness of the air outlet. 2. Using an air conditioner in an area with unstable voltage will reduce the service life of the air conditioner, so if this situation occurs in your home, it is recommended that you choose the right voltage regulator to install at home.

3. Keep the air conditioner away from the heat source as much as possible, so as not to affect the performance of the air conditioner, which may cause the deformation of the air conditioner and the louder sound in serious cases. 4. If you don't use it for a long time, open the air shield of the air conditioner, dry the moisture inside the body, unplug the air conditioner, take out the battery in the remote control, and it is best to take a cover to cover the air conditioner.

Air conditioners don't heat cooling can be why.

In addition, in winter, the ambient temperature is lower than minus 5 degrees, and the air conditioner Qingying can not effectively heat, and secondly, the refrigerant of the air conditioner is insufficient, resulting in a decrease in heat exchange efficiency, and the phenomenon of insufficient heat will be produced The air conditioner will not heat.

Extended information 1: When using the air conditioner daily, clean the filter regularly as needed to keep the cleanliness of the air outlet too mid. 2. The use of air conditioners in areas with unstable voltage will reduce the life of air conditioners, so if this situation occurs in your home, it is recommended that you choose the right voltage regulator to install at home. 3. Keep the air conditioner away from the heat source as much as possible, so as not to affect the performance of the air conditioner, which may cause the deformation of the air celery tone and the louder sound in serious cases.

4. If you don't use it for a long time, open the air shield of the air conditioner, dry the moisture inside the body, unplug the air conditioner, take out the battery in the remote control, and it is best to take a cover to cover the air conditioner.
