What to do if the heating effect of the air conditioner is poor, what to do if the heating effect of

Some friends report that their home air conditioners often have poor heating effects, why does this happen?

Please check whether the air conditioner settings are correct, such as whether the air volume and auxiliary heating are turned on. Generally, there are 6 reasons for the poor heating effect: 1. The room area is too large, which exceeds the applicable area of air conditioning heating, 2. Because the outdoor temperature is too low, it will also affect the heating effect of the air conditioner 3. The fixed-speed air conditioner does not turn on the auxiliary electric heating, 4. The air conditioner indoor unit filter has not removed dust for more than half a month 5. The lack of refrigerant leads to quite little heating, 6. The room insulation effect is poor, and Haier self-cleaning air conditioning saves you many troubles.

Generally speaking, the heating effect of air conditioners is not good, partly because the air filter has too much dust and the vents of the internal and external units are blocked by foreign objects. The function of the filter screen is to adsorb the dust in the air, if the accumulated 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 in the machine can not be brought out by the flowing air in time, resulting in insufficient heat production, this is not a fault, it belongs to the maintenance of the air conditioner, just take off the air filter regularly to clean, it can be restored to normal. Fluoride deficiency is one of them.

At present, most of my friends use heat pump type or heat pump plus auxiliary electric heating type air conditioner. 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. 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 York air conditioner is difficult to be satisfactory.

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 to this, line control failures are also common. For example, if the external unit is not working, it is most likely due to the failure of the capacitor, temperature probe or motherboard.

The fault mainly occurs on the four-way solenoid valve or its control circuit, and it may also be the AC contactor, thermostat and over-temperature fuse of the electric heater and its power supply circuit, all of which need to be detected by the master.

The reason may be that the outdoor ambient temperature is too low, which can be solved by improving the external environment used by the air conditioner. The reason may be that the air conditioner is lacking in fluoride, which can be solved by adding freon. The reason may be that the capacitor of the air conditioner motor is damaged, which can be solved by replacing the capacitor.

1. If the outdoor ambient temperature of the air conditioner is too low, it will lead to poor heating effect of the air conditioner. Therefore, it is necessary to change the temperature environment of the air conditioner. 2. If the air conditioner lacks fluorine, it will cause the heating effect of the air conditioner to be poor, and the lack of fluorine for a long time will cause the air conditioner compressor not to start, so it is necessary to add freon in time.

If the air conditioner has freon leakage or insufficiency, it is necessary to add fluoride in time. 3. Use a multimeter to check whether the capacitance of the outdoor air conditioner is burned. Once the outdoor capacitor is burned, it will cause the poor cooling and heating effect of the air conditioner, so it is necessary to replace the corresponding capacitor in time.

4. Regularly clean the filter screen of the empty talk bridge and tomb, which can improve the efficiency and service life of the air conditioner, and the summer is the peak period of air conditioning, so the filter screen of the air conditioner should be cleaned every two weeks, so as to avoid the failure of the air conditioner and ensure the smooth ventilation of the air conditioner.

Answer: The reasons for the poor heating effect of the air conditioner are different, and the solutions are also different, the specific situation is as follows:

1. The internal closure of the room is not strict, resulting in poor heating effect of air conditioning.

Solution: In the process of using the air conditioner, it is necessary to keep the room closed, so as to better ensure the heating effect of the air conditioner.

Second, the lack of regular cleaning of the air conditioner leads to the poor heating effect of the air conditioner.

If there is no grinding pin to regularly clean the dust inside the air conditioner, when the dust accumulates too much, it will cause the vents of the internal and external units to be blocked by dust, and the heating of the air conditioner will be insufficient, which will seriously affect the heating effect of the air conditioner.

Solution: Clean the air conditioner dust regularly once every three months, pay attention to cleaning the air conditioner vent to ensure the smoothness of the air conditioner vent; At the same time, it is also necessary to focus on cleaning the air conditioner's filter and other places that are prone to dust accumulation, so as to ensure the heating effect of the air conditioner.

3. The outdoor temperature is too low, resulting in poor heating effect of air conditioning.

When the outdoor temperature is too low, the outdoor unit of the air conditioner cannot carry out the defrosting work normally, and the heating effect of the air conditioner will also be affected.

Solution: Defrost the outdoor unit of the air conditioner to restore the defrosting effect of the outdoor unit of the air conditioner and enhance the thermal efficiency of the indoor mechanism. Wandering.

Fourth, the failure of the evaporator leads to the poor heating effect of the air conditioner.

The evaporator of the air conditioner is installed outdoors, so it is easy to freeze and fail, once this happens, then the air conditioner cannot be frosted, which leads to frosting of the air conditioner evaporator, and the heating effect of the air conditioner is not good.

Solution: Check whether the defrosting thermostat of the air conditioner is misaligned, the contacts are stained, or the contact is poor. Then find the fault and repair it, so that the problem of poor heating effect of the air conditioner is solved.

5. The dust will block the air conditioner filter, resulting in poor heating effect of the floating air conditioner.

Solution: The heating effect of the air conditioner caused by not cleaning in time is not good, and the filter screen of the air conditioner needs to be taken out for cleaning to keep the inside of the air conditioner indoor unit clean and tidy, so that the problem of poor heating effect of the air conditioner is solved.

Nowadays, many people will use air conditioners to heat in winter, but the effect of air conditioning heating will be worse than that of heating, so many people will feel that the heating effect of air conditioning is not very good. So, let's take a look at the reasons and solutions for the poor heating effect of air conditioners.

Reasons and solutions for poor heating effect of air conditioners

1. Improper operation: The temperature is set too low, generally the higher the setting temperature, the better the heating effect.

2. The voltage is too small: The electricity consumption in the same period of time is too large, resulting in too low voltage, which cannot meet the heating power of the air conditioner and affects the heating effect of the air conditioner. In this case, it is recommended to purchase a voltage regulator to keep the electrical voltage stable.

3. The location of the air conditioner is inappropriateWhen the room floor is too high and the air conditioner is installed relatively high, it is easy to have the problem of heating and cooling.

4. The air conditioner itselfThe original power of the air conditioner is very small, especially when the number of air conditioners does not match the area of the house, the heating effect is very poor.

5. The reason for the house: The heating area is on the large side, and the room is not tightly closed. Therefore, in the process of using the air conditioner, it is necessary to pay attention to maintaining the closure of the room and do not open the doors and windows casually.

6. Equipment dust or blockageAfter the air conditioner is used for a period of time, the filter screen and the condenser of the external unit are easy to accumulate dust, too much will block the air supply system of the air conditioner, affect the heating efficiency of the air conditioner, and even cause no heating. This situation requires timely cleaning of the equipment, including the filter screen or external condenser.

7. Air conditioner freon leakage or insufficiency:The air conditioner needs to use freon in the operation process, and if the freon is insufficient, the heating effect of the air conditioner will be very poor. Workaround:

Patching or re-adding freon leaks may require a professional to deal with them.

8. The ambient temperature is too lowWhen the ambient temperature is too low, it will be very difficult for the main unit of the air conditioner to heat up, especially when the temperature is lower than minus 5 degrees, and the heating effect of the air conditioner will be very poor if the electric auxiliary heating is not turned on. When it is lower than minus 10 degrees, even if the electric auxiliary heating air conditioner is turned on, the heating effect will still be unsatisfactory.

9. Aging of air conditioning: After the air conditioner has been used for a long time, the equipment will age to a certain extent, so the heating effect will gradually decline.

Causes and solutions for poor heating effect of air conditioners:

1.The outdoor temperature is low or the electricity environment is poor.

When the outdoor temperature is too low, the outdoor unit of the air conditioner cannot be frosted, and the air conditioner cannot heat. In addition, if the voltage is too low, it may directly affect the cooling and heating effect of the air conditioner.

2.The heating power of the air conditioner is too small.

The size of the room is different, the number of applicable air conditioners is also different, if the air in the house is not tightly sealed, the west is sun, etc., the corresponding number of air conditioners should be larger. If the room is relatively large and the number of horsepower to choose the air conditioner is relatively small, it is easy to cause this problem.

3.There is no electric auxiliary function, and the heating effect is not good.

After market research, the main reason for the poor heating effect of many air conditioners is that there is no electric auxiliary heating function, and the situation of old-fashioned air conditioners is very prominent.

4.The air conditioner filter is too 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, and the heat production is insufficient.

Five solutions to the poor heating effect of air conditioners:

1.The use of cloth curtains and spray-painted portrait partitions to reduce the area of the room;

2.Every half month, clean the filter of the indoor unit of the air conditioner;

3.When using an air conditioner, use a heater or heater at the same time;

4.When the fixed-speed air conditioner is heating, the auxiliary electric heating is turned on at the same time;

5.If the air conditioner is suspected of lacking fluoride, please check the fluoride added by the after-sales service personnel.

The poor heating effect of the air conditioner is due to the lack of fluoride in the air conditioner, and only fluoride needs to be added.

What you need to prepare for the digging tools: air conditioner, remote control.

1. Check whether the outdoor temperature is too low, generally the outdoor temperature is too low will cause some air conditioners to not work normally, and the frost covered by the air conditioner can be removed.

2. There is a situation because the air conditioner lacks freon, which mostly occurs in the air conditioner that has been used for a long time, and the problem can be solved by adding fluoride.

3. You can disassemble the air conditioner (leave a screw to prevent the shell of the air conditioner from falling), check whether the internal capacitor is burned, and check it with a multimeter.

4. You can disassemble the air conditioner (indoor nucleus) to check whether the filter screen is blocked by dust because it has not been cleaned for a long time, so that the hot air cannot be blown out.

5. If the air conditioner is within the sufficient warranty period or there is no problem with the inspection by yourself, it is better to ask a professional air conditioner maintenance personnel to repair it, which is relatively simple and safe.

Reason 1: The air conditioner heating starts slowly or the air conditioning does not heat out the air, which is likely to be the same**, because he is a disguised valve for cold and heat conversion, the compressor is protected, and after the compressor starts, the indoor evaporator (the part of the air conditioner outlet with many fins) reaches a certain temperature, and the air conditioner fan is started, so as to ensure that the air sent out is warm air. The normal start is completed in about 5 minutes, and the larger air conditioners rely on auxiliary electric heating.

So the heating time should be slower.

Reason 2: The indoor tube thermothermistor is broken, it should be a lack of refrigerant, otherwise there will be no insufficient pressure, check whether there are oil stains at each joint, if there is a leak in the place, you can use soapy water or washing spirit. If not, call the maintenance staff to check the low pressure return pressure and static pressure when the refrigeration is running, the gauge pressure should be during normal refrigeration, and if you can't refrigerate in winter, you can wrap the temperature sensor in a hot towel with hail.

Reason 3: It may be due to the fact that the lubricating oil in the four-way valve has become viscous for too long, so that it does not slide in place, you can use a wooden stick to lightly buckle the valve body during heating, and then refrigerate, reheat, knock, recool, reheat, knock, and repeat several times. The fan will only start when the temperature sensor detects that the indoor evaporator rises to a certain temperature, and the details of how many degrees are different from each manufacturer, you can check the anti-cold air function in this way:

Turn on the heat, wrap the temperature sensor with a hot towel when the wind is not blowing, and see if the wind is out for a while, if the wind is out, it means that it is good, and it will be replaced without going out of the wind.

1.Clean the air conditioner fan blades The air conditioner needs to be cleaned regularly, and if the fan blades are dirty, it will also affect the air conditioner's production concept and physical and thermal effect.

2.Check whether the refrigerant is insufficient Check whether the refrigerant of the air conditioner is insufficient, if the refrigerant is insufficient, add the refrigerant to use it regularly.

3.Check whether the air conditioner is faulty Check whether the air conditioner has some parts damaged, if there is any damage, after the replacement parts are repaired, the air conditioner can be used normally.
