Why does the air conditioning heating mode come out of the cold air?

This is not a problem with the setting or the air conditioner is faulty, first of all, if the air conditioner is cold and warm, turn on the heating mode or automatic mode, the automatic mode does not need to be adjusted, the ambient temperature is lower than 18 degrees will automatically be designed for heating, and the general heating mode can not adjust the temperature. When the ambient temperature is 2 degrees lower than the set temperature, the heating should be started, and if it is not heated, listen to the sound of the compressor of the outdoor unit running, if so, it should be refrigerant.

If it is insufficient, it is necessary to add refrigerant. If there is no sound of running, check the starting capacitors of the compressor, the compressor and the four-way valve.

Whether there is a problem. In addition, check the filter screen of the indoor unit of the air conditioner, if the filter screen is blocked by hot air.

I can't blow it out.

The heating mode of the air conditioner is normally hot air. When the temperature of the space has not risen to the point that the human body has a warm feeling, the hot air from the air conditioner may feel cool when it blows through the cold environment and blows to the human body. If the air conditioner heating mode near the air outlet is also cold air and cannot heat the space, it may be that the air conditioner is broken.

FYI.

If it is cold all the time, it means that the air conditioner is broken, and if there is cold air at the beginning and hot air at the back, this is normal.

It would be nice to turn up the temperature a little higher, the wind that started to come out was not particularly warm.

I can't repair it, so I can only find a maintenance person to take a look, and it is estimated that the tube temperature sensor is broken.

Taking a certain force air conditioner as an example, there are roughly three reasons why the air coming out of the air conditioner is cold air when the heating mode is turned on.

1. It may be caused by the control board of the internal unit stopping the power supply to the outdoor unit, because the motherboard relay of the indoor unit cannot withstand the maximum current due to the excessive running current of the outdoor unit.

2. It may also be caused by the overheating protection of the compressor of the outdoor unit of the air conditioner, and the heat dissipation effect of the outdoor unit is not good or the compressor is aging, resulting in the compressor turning off the temperature protection switch.

3. There may also be a four-way valve.

If the coil is caused by power failure, the coil needs to be replaced in time to prevent accidents.

In addition, the popular air conditioner generally turns on the heating mode, which requires 10 to 20 minutes of preheating preparation time, if the preparation time is exceeded, it may be that the air conditioner is faulty, and it is necessary to contact professionals in time for testing and maintenance.

Pay attention to the following points in the use of air conditioning heating mode.

1. The temperature setting should be appropriate, too high temperature will cause physical discomfort.

2. Keep the air circulating regularly, and you can open the window for ventilation in about two hours.

3. When the heating mode is turned on, a basin of water needs to be placed in the room, or a humidifier should be installed.

Make sure there is a certain amount of humidity in the room.

This answer applies to most brands of air conditioner models.

Winter is coming, the temperature of the air conditioner can not be too high, generally the first ten minutes are not too hot, or there is no wind directly, it is recommended to turn on the electric auxiliary heat, the temperature is set to 22-25 not too high, it is useless.

Why is the air conditioner heating and blowing cold air?

Taking Haier, Gree, and Midea air conditioners as examples, the reasons for the cold air generated by the air conditioner are:

1. When just heating, the internal machine is not windy, and the hot air will be blown after a certain temperature needs to be preheated, which is about the cold air of the air conditioner.

2. Carefully check whether the remote control or button of the air conditioner is pressed to make heating, and press the wrong button to adjust it.

3. If the temperature is not high or the air is still cold after 15 minutes of using the air conditioner, it may be that the refrigerant inside the air conditioner is leaking, and you need to find a professional to fluoride the air conditioner.

4. Generally, the air conditioner will carry out a defrosting process during the heating process, and the internal and external machines of the air conditioner will automatically stop working during the defrosting process, and the heating function will be automatically turned on again after the defrosting is over.

1. First of all, you need to confirm that you are using the remote control to press the heating mode 2. The outdoor electronic control does receive the heating signal to energize the four-way valve 3. The valve body of the four-way valve itself has turned to the valve body 4. The above are all correctly executed, that is, the outdoor unit has no refrigerant, the outdoor unit provides insufficient heat, and the indoor unit blows the air, and the heat is gone, so the wind that comes out is cold I hope mine can help you.

Why does the air conditioner blow cold air:

1. It may be because the hot air that has just been turned on is not stable, causing it to blow cold air, which is a normal phenomenon, and it will start to blow warm air after 10 minutes.

2. Or due to long-term use, the refrigerant inside the air conditioner is partially leaked, resulting in insufficient refrigerant in the air conditioner, and the wind blowing out at this time is sometimes not hot, sometimes cold air, and it is necessary to add freon to the air conditioner.

3. After the air conditioner has been used for a long time, too much dust in the filter will affect the air volume of the air conditioner, so the heating of the air conditioner is not good, and the wind blowing out does not have too much temperature, so the dust on the filter should be cleaned.

Temperature secret method: pay attention to the temperature of the air conditioner operation carefully to avoid overheating or overcooling. If the heating is lower than 2, it can save about 10% of electricity.

When the air conditioner is running, try to open doors and windows as little as possible. Frequent opening and closing of doors and windows will reduce the cooling and heating effect of the air conditioner and waste electricity. The windows of the room where the air conditioner is used should be covered with curtains.

In winter, the daylight of the white angel enters the room, and at night it is covered with curtains to prevent heat loss. Especially in summer, the direct exposure to sunlight can make the air conditioner charge about 5%. In addition, because well-insulated houses are the most energy-efficient.

Therefore, it is advisable to use insulation materials when constructing, adding to or renovating a home.

1. In view of this situation, it may be because the control circuit of the main board of the indoor unit of the air conditioner is faulty. 2. It is also possible that there is an error in the conversion of the four-way valve on the outdoor unit of the air conditioner. 3. If the system of air conditioning and refrigeration mode and heating mode is faulty or chaotic, there will also be hot air in air conditioning and refrigeration mode.

Suggested solutions: 1. If this problem occurs, it is recommended to turn off the air conditioner, then unplug the power supply of the air conditioner, let it stand for a few minutes and then plug it back into the power supply and then turn on the air conditioner. 2. If there is an error in the conversion of the four-way valve on the outdoor unit, it is not recommended to solve it by yourself, and you need to contact professional maintenance personnel in time for on-site repair or replacement.

3. If this situation occurs in the intelligent air conditioner, it is necessary for professionals to find the specific cause after testing, so as to repair or replace the original in a targeted manner.

Explain that the performance of the air conditioning control circuit is abnormal, and you should contact the after-sales service or ask a professional for maintenance.

When the air conditioner is cooling, there will be no hot air that seeps into the socks. First of all, confirm whether the air conditioner is turned on in the cooling mode, some users may be careless in the heating mode, so first confirm whether the air conditioning mode is turned on incorrectly. If there is no mistake, it is that the cooling effect of the air conditioner has deteriorated, and the wind blowing in by the air conditioner is not cold, but it is not hot, but it is just because it is not cold, so it feels like hot air.

The reason for the hot air coming out of the refrigeration mode.

1. Check whether there is still refrigerant in the air conditioner, if the refrigerant is insufficient, add refrigerant, and there will be hot air in the case of refrigerant leakage or consumption.

2. If there is no hot air at the air outlet of the outdoor unit, it is likely that the thermal protection makes the compressor not work, resulting in the air conditioner being set in refrigeration, but not refrigeration.

3. Look at the setting mode on the remote control, if the mode is indeed the refrigeration mode, it should be a broken four-way valve or a broken computer board, it is recommended to contact the after-sales service.

What to do if the air conditioner has a poor cooling effect.

1. It may be that the air conditioner lacks fluoride, at this time, check the pressure of the air conditioner refrigerant to see if there is a lack of fluorine, if it is lacking, you need to find a maintenance master to add fluoride.

2. If it is because the aging of the air conditioner is more serious, the internal refrigeration system has problems, and the general air conditioner will be seriously aged after 10 years, and the use time is too long, rather than frequent maintenance, it is better to buy a new air conditioner.

3. If the power of the air conditioner is too small, and the room at home is relatively large, the amount of refrigeration can not meet the needs of the room, which will lead to poor refrigeration effect, it is recommended to replace a more powerful air conditioner.
