The hanging air conditioner is turned on for refrigeration, and the hot air is turned off and releas

1. Check whether there is refrigerant in the air conditionerIf not, the refrigerant will be added, and the phenomenon of hot air will occur when the refrigerant leaks or is not consumed.

2. Go to the air outlet of the outdoor unit to feel whether there is hot airIf not, it is likely that the thermal protection makes the compressor not working, resulting in the air conditioner being set to refrigerate but not cooling.

3. Look at the setting mode on the remote controlIf the mode is correct, it means that the four-way valve is broken or the computer board is broken, it is recommended to contact the after-sales service.

In fact, as long as you find the air conditioning and refrigeration mode, it becomes very easy to solve the cause of the hot air, but we usually know the solution and cannot solve it by ourselves, if this is the case, contact the after-sales manufacturer of the air conditioner as soon as possible to help quickly improve the air conditioning situation.

The number of times the use of household appliances is relatively frequent, so it should be maintained during use, and the air conditioner is no exception, only by maintaining the air conditioner and using it in daily specifications, can we ensure that the air conditioner can better serve us, and the service life is longer.

Hot air is emitted in the cooling mode of the air conditioner.

"Blowing hot air" is actually the "heat" that people feel, but in fact, it is the same wind as the indoor temperature. This problem is caused by the abnormal condition of the air conditioning system, which causes the compressor to stop running, and only the indoor and outdoor fan motors of the air conditioner are working, and the role of the air conditioner is basically that of an ordinary fan.

There are many reasons that cause the air conditioner compressor to stop running, such as refrigerant leakage, outdoor fan motor capacitance aging, compressor capacitance aging, outdoor fan motor failure, compressor failure, indoor fan motor or capacitor failure, air conditioner main control electrical component failure, outdoor machine heat exchanger is too dirty, ventilation around the outdoor unit is not smooth, etc., these possible reasons will cause the air conditioner compressor to fail to operate normally.

The air conditioner is the cause of the hot gas and the solution: 1. The size of the house space and the power of the air conditioner are not well matched, so choose the matching air conditioning installation. 2. The service life of the machine is too long, and the air conditioner needs to be replaced when the life is up.

3. The filter screen is too dirty and needs to be cleaned. 4. The heating effect of air conditioning itself is worse than that of refrigeration.

There is a mold removal function, just turn off that function, turn it off according to the manual, it's very simple.

Mine too, I'm looking for a reason too.

Cause analysis When the air conditioner is turned off, in order to ensure the air circulation in the cab, the air conditioning system will automatically switch to the external circulation mode. It is normal to feel that hot air will still come out of the air outlet after absorbing the heat from the engine radiator and exhaust system when the vehicle is moving, and then enter the cab from the air conditioning distribution box, so you will feel that hot air will still come out of the air outlet after the air conditioning is turned off. ②

There is a small warm air tank in the middle of the instrument panel, which has only one partition with the air distribution pipe in the air conditioning distribution box, so there will also be heat dissipation, which will also make the air in the air conditioning distribution box hot. (2)

ConclusionWhen the air conditioner is turned off, there will still be hot air coming out of the air conditioner outlet, which is a normal phenomenon. (3)

It is recommended to adjust the temperature knob to the lowest position before turning off the air conditioner, and select the internal circulation mode to effectively eliminate this phenomenon.

After turning off the air conditioner, there is still hot air coming out of the air vent, because the machine has been running for a while, and he has to dissipate heat.

This is now a protective function of the air conditioner, which is dry and mildew-proof during refrigeration, and prevents the radiator from suddenly shutting down and overheating during heating.

In summer, after the air conditioner is turned off, the hot air comes out after the air conditioner is turned off, it may be that the purchased air conditioner product has the function of "drying and cleaning", and the machine continues to run after the shutdown; If the air conditioner has the function of drying and cleaning, if it is turned off in refrigeration, dehumidification, and automatic (refrigeration) mode, it will generally run with a breeze for 7 minutes, heating for 1 minute, and natural wind infiltration for 2 minutes after the air conditioner is turned off to keep it running, dry and dehumidify, and prevent the air conditioner from working in a humid environment for a long time, resulting in mildew, odor and other problems; If you need to turn off the dry rock shouting group cleaning function, you can select the "air supply" mode before shutting down, and then press the "power off" button, or you can select "hot drying" to turn off the "hot drying" button on the remote control of the air conditioner. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again! <>

Problems with the electronic control system, confusion in hot and cold modes.

The temperature sensor fails, and the protection against overcooling and overheating is ineffective.

There is a problem with electric heating.

The quality of the product itself.

Air conditioner open refrigeration hot air solution:

1) There are many reasons that cause the air conditioning compressor to stop running, such as refrigerant leakage, outdoor fan capacitor aging, compressor capacitance aging, outdoor fan motor failure, compressor failure, indoor fan motor or capacitor failure, air conditioning main control electrical component failure, outdoor unit heat exchanger is too dirty, ventilation around the outdoor unit is not smooth, etc., these possible reasons will lead to the air conditioning compressor can not operate normally. When this phenomenon occurs, you can observe the operation status of the air conditioner for a long time, such as whether it is intermittent or continuous, etc., and then report to the maintenance company for repair, and send maintenance personnel to come to the site for maintenance.

2) There is a problem with the capillary or check valve of the air conditioner, and replacing the capillary or check valve can solve the problem that the air conditioner does not heat.

3) Replace the operation in order to deal with it effectively and properly, and the specific implementation details can be referred to by relevant personnel.

For details, please call us or make an appointment for maintenance.

...It's so complicated, I didn't figure it out. Does it mean that hot air comes out when the air conditioner is cooling? Trouble the landlord to say it simply.
