What is the reason why the air conditioner does not get hot air

The reasons why the air conditioner does not produce hot air are as follows: 1. The problem of the air conditioner: the filter screen of the air inlet is not clean enough, and the solution is to remove the filter screen of the air inlet of the air conditioner and clean it.

2. External compressor problem: where there is a lack of freon or fluorine leakage, the solution is to repair the fluorine leakage of the compressor of the air conditioner. 3. Problems with air conditioners:

There is dirt on the aluminum sheet, which makes the heating effect worse, and the solution is to wipe off the dirt on the aluminum sheet of the air conditioner. 4. The problem of the internal unit of the air conditioner: the evaporation place is blocked, and the solution is to unblock the evaporation blockage of the internal unit.

The air conditioner is not hot Reason:

1. There is a problem with the capillary or check valve.

This is also the main reason why the air conditioner does not heat, whether it is air conditioning heating, refrigeration, all are the use of capillary network to quickly dissipate heat, dissipate cooling, if the capillary network is damaged or there is a problem, even if it can be heated and cooled, the whole house is very slow to heat up, because there are no two things to prevent the reverse flow of air, these two things are damaged, and there may even be reverse cooling and heating effects, to solve this problem, you can directly find a professional to repair and replace.

2. The indoor temperature is too low.

In this case, it can only appear in the cold northeast, the indoor temperature may reach about minus 30 degrees, if the floor heating is damaged, the whole family can only rely on the air conditioner for heating, at this time the air conditioner has been frostbitten, the main role of the air conditioner is to inhale cold air into the four-way valve little by little heating, but if the air conditioner has frost inside, that is to say, the parts inside the air conditioner can not work normally at all, and the moisture of the frost directly causes the air conditioner to be short-circuited and damaged after the power is turned on. So in this case, be sure to give priority to using tools to clean all kinds of frost on the air conditioner.

3. There is too much dust on the filter screen.

There are scientific studies to prove that the filter screen of the air conditioner is the dirtiest place, and the problem of headache and nausea may occur when the air conditioner is blown for a long time, generally because the air conditioner is used for too long, and the filter is immersed in a large number of dirty things, which are carrying a large number of bacteria and viruses. If the air volume at the air outlet decreases, the whole house will not be warmed up for an hour.

4. The air conditioner lacks freon.

Generally, everyone's impression is still that Freon is a refrigeration material, but the lack of Freon will also directly affect the heating effect, which has to mention the working principle of air conditioning, which is generally the use of electric heating, so the working principle is generally the use of Freon evaporation, why sit on a pot of hot water after lifting the lid of the hand will be particularly hot, because the water vapor meets the solid, condensed into water droplets, in this case it is exothermic, the working principle of Freon in the air conditioner is that the solid becomes gas, and this process is also exothermic. That's why it is said that the snow does not turn cold.

Hello, the reasons why the air conditioner does not produce hot air: 1. The filter screen of the air inlet of the air conditioner is not clean enough;

2. The external compressor lacks freon or has fluorine leakage;

3. There is dirt on the aluminum sheet of the air conditioner, which is the deterioration of the heating effect;

4. The evaporation place of the internal machine is blocked.

The solution to the poor heating effect of the air conditioner is as follows:

1. Remove the filter screen of the air inlet of the air conditioner and clean it;

2. Repair the fluorine leakage of the compressor of the air conditioner;

3. Wipe off the dirt on the aluminum sheet of the air conditioner;

4. Unblock the evaporation blockage of the internal machine.

Air conditioner hot air no wind reasons:

1. When the air conditioner is turned on for heating, the air conditioner generally has a preheating period, and it is generally necessary to wait for the outdoor compressor, motor, fan, etc. to run for a period of time, and the indoor unit will start to blow air, and the blowing is hot air, which is the "anti-cold air" function of the air conditioner, the purpose is to prevent the indoor unit of the air conditioner from blowing cold air and making people feel uncomfortable.

2. When turning on the air conditioner for heating, if the outdoor temperature is very low, then the air conditioner generally needs to be defrosted first, and the defrosting time generally takes about ten minutes, and the indoor unit has generally not started to run at this time, so there will be no wind, after the defrosting is completed, the indoor unit will start to run, and then it will start to supply air.

Tips: The phenomenon of air conditioning heating and no wind is generally temporary and normal, but if the air conditioner has no wind for a long time, it may be caused by the leakage of refrigerant, the failure of the air conditioning motor and fan, and then you should ask professionals to help you with testing and maintenance.

Proper use of air conditioning:

1. When you first enter the room, do not turn on the air conditioner immediately, and generally take a break for a while before turning on the air conditioner after entering the room. Because when you first enter the room, your body is still sweating, and your pores are loose, so if you turn on the air conditioner immediately, it is easy to feel uncomfortable. Before going to bed, it's best to put the air conditioner into sleep mode, and it's best not to leave it on all night.

2. In the process of using the air conditioner, a basin of water should be placed around the air conditioner, or a humidifier should be placed indoors, the purpose of which is to prevent the indoor air from becoming dry, causing the human body and eyes to become dry and uncomfortable.

In addition, doors and windows should be opened regularly for ventilation to avoid indoor air pollution all the time, under normal circumstances, after every 1 hour of air conditioning, it should be ventilated for about 10 minutes.

First of all, see if your air conditioner model has a heating function, and some models do not have heating.

If there is a heating function, but it cannot be heated, it may be caused by the following reasons:

1. There is a problem with the capillary or check valve of the air conditioner Solution: Replace the capillary or check valve to solve the problem of the air conditioner not heating. Know.

2. The outdoor temperature is too low. Solution: Use a tool to clean the frost on the air conditioner to solve the problem that the air conditioner does not heat.

3. Air leakage from the four-way valve of the air conditioner. Solution: Replace the four-way valve to solve the problem of air conditioning not heating. Inside.

4. There is dust on the filter screen, so that the heat production in the container cannot be brought out by the flowing air in time, resulting in insufficient heat production. Solution: Clean the filter screen to solve the problem that the air conditioner does not heat.

5. Lack of fluoride in the air conditioner. Solution: Add fluoride.

The air conditioner does not produce hot air, it may be that the air conditioner is defrosting, the air conditioner is easy to frost during the heating process, the electricity meter at home is flying, and the temperature in the room cannot be raised. Especially in wind, snow, wet and cold weather, the worse the heating effect.

There is an energy window air conditioner that is not afraid of wind, snow, wet and cold, which is dual-purpose, saving electricity and worry, and is a substitute for teacher air conditioning in the heating area. Since 2019, the ** "electricity instead of coal" project in Zibo City, Shandong Province has been widely used.

Not afraid of wind and snow interference, prevent and control debris blocking the heat exchanger, less frost in winter, fast frosting, and greatly improved comprehensive energy efficiency. At the same time, it is equipped with DC inverter ultra-low temperature compressor, which does not require electric auxiliary heating and heating, saves 50 75% of electricity, operates efficiently at -20°, and outputs "strong heat", also known as "strong heat energy window air conditioner".

Generally, there is a lack of fluoride, so it is good to find someone to add some fluoride.

1. Lack of fluorine, when the outdoor unit is piped, the connecting pipe between the outdoor unit and the indoor unit is relatively long. If the outdoor unit lacks fluorine, the heating effect of the air conditioner will be too poor, and the air conditioner will take a long time to gradually produce hot air. This requires timely fluoride.

2. The filter is too dirty. The air conditioner has been used for a long time and has not been cleaned since I bought it. If the filter is not cleaned, the filter is too dirty, and the hot air of the air conditioner is not easy to blow out.

At this point, it is necessary to clean the filter. 3. The wind deflector is faulty, and in order to reduce the direct blowing of the air conditioner to people, the wind deflector was bought. The wind deflector is not properly installed, resulting in a blockage of the air conditioner's air outlet.

The air outlet of the air conditioner will be small. Although the air conditioner can blow normally, it can't blow you. This solution is also relatively simple.

Adjust the wind deflector or remove the wind deflector directly. 4. Outdoor and damaged. If the air conditioner is turned on and does not heat up or blow, it may also be the cause of the outdoor unit.

You can reboot it and listen carefully to see if the outdoor unit is working properly. If there is no running sound, it is very likely that the outdoor unit is broken.

1. When the outdoor temperature is lower than 0 degrees Celsius, the outdoor unit of the air conditioner will immediately frost, and when the user turns on the air conditioner for heating, it takes about 8-12 minutes to "defrost", and some users mistakenly think that the heating effect of the air conditioner is not ideal.

2. Due to improper use and maintenance by users, etc.

3. The reason why the air conditioner cannot work normally is because the power consumption increases greatly, which may cause the regional power supply voltage to be unstable or too low.

4. There may be a lack of fluorine, at this time we need to ask after-sales service personnel to check the fluoride. Most users use heat pump type or heat pump plus auxiliary electric heating type air conditioner.

5. The applicable area of air conditioning heating is smaller than the area of the room using air conditioning, resulting in the room temperature not rising ideally, that is, the customized heat is not enough. At this time, we need to use cloth curtains and spray-painted portrait partitions to reduce the room area; -5 degrees below it is recommended not to turn on the air conditioner, use auxiliary electric heating, use wall-hung boiler or heater; When using air conditioners, we try to avoid using air conditioners during peak hours.

6. The reason why it affects the heating effect of the air conditioner is because the outdoor temperature is below -5. The lower the outdoor temperature, the worse the heating effect of the air conditioner, and the actual heating is not enough.

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

The car air conditioning heating system is not hot can be divided into two reasons, one is caused by the engine cooling system, and the other is caused by the poor work of the heating control mechanism.

The method of judging is very simple, look at the temperature of the two inlet pipes of the small water tank of the warm air, if the two pipes are hot enough, it means that the air volume control mechanism is a problem, on the contrary, if the two water pipes are cold, or one is hot and one is cold, it means that it is a problem with the cooling system.

Problems that can arise with the cooling system:

1. The thermostat is always open or the thermostat is turned on too early, so that the cooling system is prematurely circulated, and the external air temperature is very low, especially when the car is running, the cold air quickly cools the antifreeze, the engine water temperature does not rise, and the warm air will not be hot.

2. The impeller of the water pump is damaged or lost, so that the flow through the small water tank of the warm air is not enough, and the heat cannot come up.

3. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and unheated heat. If there is always gas in the cooling system, it is likely that the cylinder head gasket is damaged and the gas is flowing into the cooling system; If the inlet pipe of the warm air small water tank is very hot and the water outlet pipe is cold, this situation should be that the warm air small water tank is blocked, and the warm air small water tank should be replaced.

Problems with the air volume control mechanism:

1. The warm air of the car is to use the blower to blow the heat of the small warm air tank into the cab, if the air volume is not enough or the hot and cold air is not well distributed, the heat of the small warm air tank can not be dissipated, and the temperature of the warm air can not come up. At this time, it is necessary to check whether the filter is dirty and blocked, clean it, and replace it in time if necessary.

2. Check the operation of each gear of the blower, and each gear must reach sufficient speed. If the knob is adjusted to the position of the warm air, the air volume is large enough, the wind direction is normal, and the cool breeze blows out, you should check whether the control flap cable of the hot and cold air box falls off, whether the warm air impeller is damaged, whether the flap falls off, etc., and the warm air will heat up after troubleshooting.

Fault and elimination of air volume control mechanism.

1) If the fuse of the heater circuit or its control circuit is blown or the switch is in poor contact, replace the fuse or switch.

2) Short circuit or open circuit of the motor winding of the heater, repair or replace the fan motor.

3) The heater speed control resistor is broken, the fan relay is faulty, the fan circuit wire connection is faulty, etc., which should be repaired or replaced.

4) Heater flap failure.

Faulty pipeline leakage.

1) If the pipeline is aging and faulty, replace the hose.

2) If the joint is not firm and the seal is not tight, the joint should be repaired and fastened.

3) The hot water switch cannot be closed and faulty, repair the hot water switch.

1. Air conditioning anti-cold air system.

The air conditioner will not blow the air immediately within 10 minutes before it is turned on, because the air conditioner has the function of preventing cold wind, and the wind blowing in when the air conditioner is just turned on will be cold, which will affect the user's heating experience, so the air conditioner coil unit has a temperature sensor, and the air outlet will be opened only when the wind blowing in from the outside unit reaches the temperature.

2. The air conditioner is defrosting.

If the air conditioner is still working normally just now, suddenly there is no hot air, it is very likely that the air conditioner is defrosting, the external unit will not work when the air conditioner is defrosting, the internal unit will not blow the air, only the compressor will work to reverse the heat circulation to defrost, at this time there will be a few minutes to stop the phenomenon of blowing, and the defrosting will start to heat.

3. The air conditioner reaches the set temperature.

The air conditioner does not blow the air, the most likely is that the temperature inside the room has reached the temperature, it may be that the temperature set by the user is not high or the air conditioning performance is good, the room will stop blowing soon when it reaches the set temperature, and it is unrealistic for the air conditioner to keep blowing hot air, which is a waste of electricity, so the air conditioner will stop after working to the set temperature, these are the characteristics of fixed-frequency air conditioning.

4. Air conditioning thermal protection.

If the air conditioner automatically shuts down and does not blow hot air, it may also be that the air conditioner has overheating protection, the more common reason is that the air conditioner filter is blocked and the heat cannot be blown out normally, then the coil temperature is too high, it will be automatically protected, clean the air conditioner filter and then turn it on again.

5. Failure of the external unit of the air conditioner.

The premise of the air conditioner blowing hot air is that the outdoor unit is working, we can open the window to listen to whether the outdoor air conditioner is working, if there is a sound indicating that the outdoor unit is normal, if there is no work, the external unit can not be heated if it fails, please check the failure of the outdoor unit **.
