Why does the air conditioner sometimes not cool down, but the natural wind blows?

1. There are many reasons why the air conditioner cannot be refrigerated when it is windy

1. Whether the set temperature is lower than the actual temperature of the room; Because when the set temperature is reached, the compressor will automatically shut down.

2. Whether the compressor is running normally; This is because it is impossible to refrigerate the compressor if it is not running.

3. The compressor cannot be refrigerated after running: the pressure of the refrigerant (fluorine) drops (fluorine leakage).

4. Whether the function setting of the remote control is wrong (whether it is in the refrigeration function).

2. Solution:

1. Generally, when the air conditioner is purchased, it will come with freon, at this time, you can add it yourself, if not, it is best to find a maintenance master to help you. It is also important to note here that you should not overuse freon, which will be counterproductive.

2. Try to shorten the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner.

3. Clean and maintain the air conditioner to make the clean outdoor unit more tolerant of late heat dissipation.

4. Ensure that the voltage at home is stable, especially during the peak period of electricity consumption, buy a higher resistance and voltmeter to monitor the voltage at all times.

5. Change the use environment of the outdoor unit, and try to install it in a well-ventilated place.

Even if the refrigerant is added, you need to check whether your compressor is working, if the fuse of the compressor is broken, it will cause the compressor to not work, there is no cold air, the first part to check the compressor worker is not working, if it does not work, check the insurance or line, and there is a problem with the compressor itself, I hope it can help you, thank you.

Summary. 3.The copper pipe of the air conditioner is too long, which leads to too much loss of the cold air in the air conditioner condenser tube, resulting in the poor refrigeration capacity of the air conditioner, and the only way to replace the copper pipe is to replace it with a new one.

Hello, it's an honor for me to answer your questions, it will take a little time to sort out the answers, please be patient

Hello, glad to answer for you. The air conditioner does not refrigerate, there is only natural wind, and the causes and solutions are as follows<>

1.As long as the air conditioner is used for a long time, the air conditioner lacks fluorine, resulting in a decrease in the refrigeration capacity of the air conditioner or no refrigeration.

2.If the air conditioner's filter is dirty and the refrigeration capacity at home is not good, you might as well remove the air conditioner filter and clean it, or replace it with a new air conditioner filter.

3.The copper pipe of the air conditioner is too long, which leads to too much loss of the air conditioner air conditioner in the air conditioning condenser tube, resulting in the deterioration of the refrigeration capacity of the air conditioner, and the only way to replace the copper pipe is to replace the new one.

4.Some families buy **air conditioners, and there is a problem with the ventilation pipe of the air conditioner, which leads to ventilation problems, which affects the refrigeration capacity of the air conditioner.

Air conditioner, also known as air conditioner, refers to the equipment that uses manual means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in the building or structure. Generally, it includes cold source and heat source equipment, cold and hot medium transportation and distribution system, terminal device and other major parts and other auxiliary equipment.

Freon is not enough (commonly known as "refrigerant" is not enough).

When the ambient temperature is about 35 degrees Celsius, 1, low pressure and high pressure 3, static pressure. This is a normal situation, usually in the case of an old air conditioner that has been used for three to four years. The air conditioner did not completely stop cooling, but the effect of cooling decreased.

This is because old air conditioners use freon as a refrigerant, which will volatilize after long-term use. Therefore, users only need to add a little to the regular air conditioning maintenance point. In addition, it is not excluded that improper installation can cause freon leakage and problems with the machine itself.

Do not wash and maintain for a long time.

If you want the air conditioner to operate normally and not affect human health, but also to prolong the life as much as possible, obviously, it is impossible to leave it alone as soon as you buy it and install it. Because the outdoor unit is exposed to the outdoors, it is easy to absorb dust and debris, and if it is not cleaned for a long time, it will affect the heat dissipation performance of the machine, resulting in the reduction of the cooling effect of the air conditioner. The indoor unit is related to the health of the human body, and if it is not cleaned for a long time, it will breed bacteria, pollute the air, and make people sick.

The supply voltage is not enough.

The normal starting voltage of the air conditioner is 220 volts plus or minus 10%. In China's power supply system with a phase voltage of 220 volts and a line voltage of 380 volts, almost all compressors above 200 volts can be started. At 180 volts or more, 70-80 can be started, and above 160 volts, only a few can be activated.

I've done it myself. Below 160 volts it is almost impossible to start. As a rule of thumb, the compressor starting voltage is more reliable above 190 volts.

The air conditioning was not powerful enough.

The selection principle of general air conditioning is: 150-250 watts square meters for cooling, 250-350 watts for heating, in addition to comprehensive consideration of space height, level orientation, sealing performance and residential population and other factors. Any one of these factors will have a certain impact on its cooling effect.

The ambient temperature is too high.

There is a common saying: when the outdoor unit is in an environment above 43°, most air conditioners are difficult to transfer the heat from the indoor to the outside, resulting in no refrigeration.

The copper tube connecting the indoor unit and the outdoor unit is too long.

The allowable length of the connecting pipe of the air conditioner shall not exceed 8 meters for one horse, 10 meters for horses, and 15 meters for more than 2 horses. The height difference between indoor and outdoor units shall not exceed 5 meters.

First check whether the remote control mode is selected correctly, if the refrigeration mode is selected, it is not refrigerated, then it needs to be repaired.

The pressure is normal and there is no leakage, check the operating pressure without refrigeration, since the pressure should be pumped at least 30 minutes before adding refrigeration, and the water in the system should be pumped as much as possible, in addition to the purity of the refrigerant, this step is the most critical, otherwise it is easy to produce ice blockage, especially in the case of high speed and low water temperature, this step has not been described by you, presumably you have not paid attention to this importance, or you have seen it.

It may be that the control motherboard is broken, or it may be that the refrigerant is lost, so replace the refrigerant!

The first is to confirm whether the remote control mode is in the cooling state, and the second is to check the set temperature, if the set temperature is higher than the room temperature, the compressor will not be cooled.

It may be because the air conditioner is set to be automatic, so he blows the natural wind and turns on the refrigeration, and if he does not refrigerate, it means that there may be a lack of refrigerant, and the maintenance personnel of the air conditioner should be called to repair it.

It could be that there is a problem with the air conditioner, or it may be that you have set it up to blow natural wind, and if you can't solve it yourself, you can ask the staff for help.

In this case, it depends on the mode set by the remote control and the temperature set to be higher than the indoor temperature.

Most of them are caused by low voltage and unstable voltage.

Summary. Hello, I am happy to answer for you, a large part of the reason why the air conditioner does not refrigerate may be the lack of fluoride, and you need to add liquid freon. However, it is not excluded that it is because the temperature of the opening itself is relatively low, and the stains are relatively large, so it is not enough to make the whole house cool.

Why does the air conditioner sometimes not cool down, but the natural wind blows?

Hello, very high this pure interest to answer for you, a large part of the reason why the air conditioner is not refrigerated may be the lack of fluoride, you need to add liquid fluoride pants Lu Leon. However, it is not excluded that it is because the temperature of the forest itself is relatively low, and the stains are relatively large, so it is not enough to make the whole house cool.

Other fragmentary reasons, such as the window is not closed, the door is open or the fight is that the temperature is relatively high, and the sun is more, it is possible to make silver big, but these factors are relatively low.

It is also a cool breeze when the outer J machine blows out.

It's always been a natural wind.

Whether the refrigeration can be turned on, if the device can be turned on and the refrigeration is also displayed, that is, the temperature has not dropped, then it is necessary to add liquid freon.

When the air conditioner is turned on, it blows out natural wind, and the outside unit is also natural wind.

Then let people add freon, under normal circumstances, it costs 50 100 pieces of liquid to add once.

Oh oh thank you.

1.The refrigerant in the refrigeration line of the air conditioner leaks and reduces the cooling capacity. If it is a refrigerant leak, then it is time to have a professional repair and fluoride (refrigerant).

2.Check the outdoor unit, under normal circumstances, if there is too much dust on the radiator of the outdoor unit, it will also cause the air conditioner to work normally, but the temperature of the air outlet of the indoor unit is high, which reduces the cooling capacity of the air conditioner.

3.The power supply voltage is low, the outdoor compressor of the air conditioner is not started, and the machine is not working in the refrigeration state, so the wind blowing is not cool.

4.The room is large and the air conditioner is small, and there is no air conditioner with normal cooling capacity in proportion (such as a room of 30 square meters, you go to install a small machine, that is, 32 hang-up), so the cooling capacity of the refrigeration cannot meet the requirements, so the temperature cannot be lowered.

5.The indoor unit mesh is too dirty and not cleaned, resulting in too high pressure in the refrigeration system, so the air conditioner will automatically take protective measures.

There are many reasons why the air conditioner does not refrigerate, the external unit does not start, improper operation and performance problems will cause the air conditioner not to refrigerate.
