What s the deal with the air conditioner not being cool enough? The air conditioner will cool but no

1.First check whether the air conditioner is working properly, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit. If one of them doesn't work, you'll have to get a master to fix it.

2.Then, check the air conditioner's filter. If the air conditioner starts normally, but the air conditioner can't run away, it is likely that the filter is too dusty.

It is best to spray with a filter cleaner designed specifically for doors. 3.Check for insufficient refrigerant, also known as freon.

If not enough, add freon. At the same time, check whether there is air leakage in the cold circulation system. If there is an air leak, it must be repaired.

4.If the air conditioner is working properly and there are no above problems, then check how well the air conditioner fan is working. If the fan air volume is very small, it may be that the fan motor is old and needs to be replaced with a new one.

5.If the air conditioner's ventilation duct is installed for a long time, it may be less effective at transferring heat from the room to the outside, resulting in a situation where the cooling is not obvious. It is best to find a good location to reinstall and minimize the ventilation ducts.

6.If the air conditioner is running normally, everything else is fine, but there is no air conditioner in the room, then there is only the air conditioner when it comes to the air conditioning outlet. Probably because the air conditioner horsepower is too small and the room space is too large.

At this time, it is best to change to an air conditioner with more horsepower.

What is the matter with the air conditioner not being cool enough, because the wind blowing out of the air conditioner is the kind of cold air, if the cold air and hot air are convection, the cold air will be directly pressed to the bottom, so when you install the air conditioner, you must arrange the air conditioner, that is, it is safe, install it in a lower place, do not install it in that high place, on the contrary, it affects its heat dissipation.

The reason why the air conditioner is not refrigerated is one: freon is not enough (also known as "refrigerant" is not enough) This is a normal situation, generally appears in the use of three to four years of old air conditioning, air conditioning is not completely refrigerated, but the refrigeration effect is not good enough, this is because the old air conditioner is using freon as a refrigerant, long-term use will volatilize, in addition, it is not excluded that improper installation caused by freon leakage and the problem of the machine itself.

The solution of air conditioning is not cooling: the problem of air conditioning not being refrigerated can be solved by adding refrigerant.

The second reason why the air conditioner does not refrigerate: the voltage of the power supply is not enough.

The power supply voltage is unstable, and it often fails to reach the normal voltage, especially during the peak of electricity consumption. Of course, this kind of problem is obviously not something that a skilled air conditioner maintenance master can solve, and it must be solved from the aspect of providing a stable voltage.

The solution of air conditioning is not cooling: maintain the normal power supply voltage or choose inverter air conditioning.

The third reason why the air conditioner does not refrigerate: the power of the air conditioner is not enough.

This is also one of the common reasons for not refrigerating, but there are many reasons for this kind of non-refrigeration, such as: small power air conditioning pipes in a large area of the room, and some although the air conditioning power and the room area seem to match, but because the room is relatively unsealed (such as doors and windows are wide open, etc.), or there is a heat source in the room (such as a lot of computers) of course, the glass room is also one of the heat sources, and so on.

1. The room is large and the air conditioner is too small, or the sealing and insulation conditions of the room are too poor;

2. The radiator of the outdoor unit of the air conditioner is too dirty or the fan speed is slow, or the fan speed of the indoor unit is too slow;

3. The air conditioning pipeline is damaged and leaked, resulting in the lack of fluorine in the pipeline, you can check the temperature of the thick pipe of the outdoor unit when the air conditioner is working, if the temperature is not very cold, it is mostly due to the lack of fluorine.

4. The pipeline is dirty or ice blocked.

5. Four-way valve leakage or air string.

5. Freon is not enough (also known as "refrigerant" is not enough).

This is a normal situation, generally appears in the use of three to four years of old air conditioners, air conditioning is not completely not refrigerated, but the effect of refrigeration is not good enough, this is because the old air conditioners are used as freon refrigerant, long-term use will volatilize, in addition to improper installation caused by freon leakage and the machine itself problems.

1. The air conditioning mode is set incorrectly: use the air conditioning remote control to adjust the air conditioning mode to refrigeration, and adjust the temperature to below room temperature (about 26 degrees Celsius is preferred);

2. Air conditioning refrigerant leakage: check whether the pipes, air conditioning pumps, condensers, evaporation boxes and other parts in the air conditioning system are damaged, contact the after-sales service for maintenance and re-add the refrigerant;

3. The heat sink of the condenser is too dirty: use a high-pressure water gun to clean the heat sink of the condenser, and use a high-pressure gun to dry it after cleaning;

4. Internal damage to the air conditioning pump: Check whether the air conditioning pump is damaged, contact the after-sales service or professional third-party maintenance organization to replace the air conditioning pump.

Fault: 1. Whether the air inlet hole is closed.

2. Whether the condenser coil and heat sink are clean.

3. Whether the refrigerant in the system is sufficient.

4. Whether the blower motor is working properly.

5. Whether the blower channel is blocked.

6. Whether the air inlet filter element is blocked.

7. Whether the evaporator is blocked.

Determine the cause of air conditioner failure according to the following ways:

1. If the high-pressure gauge shows normal pressure and the low-pressure gauge shows high pressure, it means that the evaporator, pressure regulator, hot gas bypass valve and intake throttle valve are faulty;

2. If the temperature of the exhaust air is high, and the pressure indication of the pressure gauge is normal, or high, and the low pressure increases slightly, the expansion valve filter screen is blocked;

3. If the high pressure gauge indicates that the pressure exceeds the normal pressure, and the low pressure gauge indicates that the pressure is lower than the normal pressure, and the receiver dryer and pipeline are frozen, the receiver dryer filter screen is blocked;

4. If the high pressure gauge indicates that the pressure exceeds the normal pressure, there may be too much moisture in the system. If air bubbles are found in the observation window, air is mixed into the system.

1.Recommended setting temperature for refrigeration: 26-28 degrees Celsius.

2.You can find after-sales service personnel to check and add air conditioning refrigerant (freon).

3.Pay attention to cleaning the filter, it is best to clean it once in about 15 days.

4.Do not place items at the air inlet and outlet of the air conditioner, otherwise it will affect the refrigeration effect of the air conditioner, and foreign objects should be removed.

5.The size of the room should be considered when choosing an air conditioner, and if the room is too large, you can also use a partition such as a curtain to reduce the size of the room. If there is a heat source in the room that affects the refrigeration of the air conditioner, the heat source in the room should be kept at a certain distance from the air conditioner.

6.If the air conditioner is installed unreasonably, you can find an installer to reinstall and arrange. If there is a quality problem with the newly bought air conditioner itself, you can contact the merchant for replacement or repair.

If the air conditioner is not cool enough, first of all, you need to see if your temperature is adjusted correctly, if it is adjusted well, it is still not enough to refrigerate, then the air conditioner may need to be fluoridated. It's also possible that the engine that refrigerated it was broken.

Some novices often envy the air conditioner in other people's cars so cool, and their own car turns on the air conditioner to the maximum, at most it just feels "not too hot", and every time the air conditioner is turned on in the sun, it takes a long time to cool down in the car. You're probably ignoring the role of the inner and outer loop buttons. If the vehicle activates the air circulation inside and outside the air conditioner, the cooling effect will be significantly reduced, but the advantage is that the air is relatively fresh.

On the contrary, if the internal circulation of the air conditioner is simply used, the cooling capacity will be greatly improved, but the disadvantage is that there is a lack of internal and external air exchange, and the air in the cabin is not fresh enough.

The air outlet temperature of the air conditioner outlet is about 13-15 degrees Celsius, if the air outlet temperature is much higher than this value, it means that the refrigeration effect is not good, see if there is a lack of refrigerant.

If the refrigeration temperature of the air conditioner is not enough, you can let professional technicians check whether the dose of refrigerant of the air conditioner is within the specified range.

The freshly changed freon, one hundred and six, is very good. If it's not cool, it may be that the fan is not good, so let them flush the front face sideways when washing the car.

I think I need to add freon.

1. Double-layer louver tuyere, double-layer louver tuyere is generally used as an air supply outlet, and can also be directly used with fan coil unit, which is widely used at the end of centralized air-conditioning system, and can also be combined with a bisecting multi-leaf regulating valve to adjust the air volume. 2. Single-layer louver tuyere, single-layer louver tuyere can be adjusted upwind and downwind direction, return air outlet can be used in combination with tuyere filter, segment angle can be adjusted, and there is AB between the blades

The air conditioner cools but is not cool enough for the following reasons:1. Insufficient refrigerant: If the freon used in the refrigeration system is insufficient, the refrigeration effect of air conditioning will deteriorate.

2. Insufficient power supply voltage: when the power supply voltage is reduced, the cooling effect will not be obvious during the peak period of electricity consumption.

3. The radiator has not been cleaned for a long time: the heat dissipation effect of the radiator that has not been cleaned for a long time will affect the efficiency of the entire air conditioner operation, and the refrigeration effect will decrease.

Reasons why the air conditioner is not cooling and what to do if the air conditioner is not cooling.

One of the reasons why the air conditioner does not refrigerate: The air conditioner has reached its service life, the normal service life has expired, and the air conditioner is aging.

Solution: Replace it with a new one!

The second reason why the air conditioner does not refrigerate: the refrigerant is not enough, that is, the freon is not enough, and the refrigerant is not enough.

Solution: Generally, freon will be included when you buy an air conditioner, 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.

The third reason why the air conditioner does not refrigerate: the copper pipe between the outdoor unit and the indoor unit is too long.

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

The fourth reason why the air conditioner is not refrigerated: the air conditioner is not cleaned and maintained for a long time, resulting in no refrigeration.

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

The fifth reason why the air conditioner does not refrigerate: the household voltage is not enough, the power supply voltage is abnormal, sometimes high and sometimes low.

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

The sixth reason why the air conditioner does not refrigerate: the power of the air conditioner is not enough to not refrigerate.

Solution: When purchasing an air conditioner, estimate the practical area, and if the funds are sufficient, you can increase the number of horses on the basis of the appropriate number of horses.

The seventh reason why the air conditioner does not refrigerate: the air conditioner does not refrigerate due to the high temperature of the outside environment.

Solution: Change the use environment of the outdoor unit and install it in a well-ventilated place as much as possible.

The poor refrigeration effect of air conditioning is a lack of fluorine, which is not entirely correct.

If the air conditioner is not cold enough, the refrigerant in it is generally gone, and the dust on the filter screen will affect the refrigeration.

Probably, there is a lack of fluoride. Find a professional and debug.

1. Keep the return air filter of the indoor unit clean and keep the ventilation around the indoor unit smooth. 2. Regularly clean the dust on the surface of the heat exchanger of the outdoor unit to keep the ventilation around the outdoor unit smooth. 3. According to the state of the air conditioning system, determine whether the refrigerant in the pipeline of the air conditioning system is sufficient, and add it appropriately.

4. Adjust the air guide strip of the air outlet of the indoor unit to the corner hail of the air outlet above the oblique front.

1. The fan blade of the fan is broken, and the air source cavity burner will be very loud. Or the air conditioner heat sink is dusty, which causes the heat dissipation of multiple heat pipes to be poor, which increases the power of the compressor and causes the vibration to increase!

2. The sound of the compressor is normal, and the vibration of the air conditioner is mostly due to the compressor problem, and the loose screws may cause the shell and the pressing machine to stick together, causing vibration and noise.

3. If the copper pipe of the air conditioner is compressed, resulting in the smooth flow of R21, it will also cause the compressor power to increase and cause violent vibration!

4. There is also a lack of freon. It will also increase the power of the compressor and increase the vibration!

insufficient freon (often referred to as "refrigerant insufficiency"); The air conditioner is not cleaned or maintained for a long time during use; The external environment temperature is too high, and the external unit is not cooled; The power supply line is damaged and the power supply voltage is insufficient; The copper tube between the outdoor unit and the indoor unit is too long. Details of the specific reasons for not refrigerating: 1. Insufficient Freon (commonly known as "insufficient refrigerant"):

It usually occurs in air conditioners that have been used for three or four years, and the effect of air circulation refrigeration is not very good, because the condition of the air conditioning system has decreased over time, because the old air conditioners use freon as a refrigerant for air conditioners, which will volatilize after long-term use. 2. The air conditioner is not cleaned and maintained for a long time: after a long time of idle and use, the filter screen, wind blades and wind wheel of the internal unit will absorb a lot of ground dust, resulting in a very low temperature of the indoor unit air outlet, but the wind is not far away, and the room circulation slows down, resulting in poor refrigeration effect.

3. The external ambient temperature is too high and the external unit is not cooled: if the temperature around the outdoor unit of the air conditioner is too high, it will cause the air conditioner to output heat in the radiator, and when the outdoor temperature generally exceeds 43 degrees, the air conditioner will not be able to send the hot air inside to the outside, resulting in the air conditioner not being refrigerated. 4. The power supply voltage is not enough

If the power supply line is damaged or closed, or during peak electricity consumption periods, the voltage will not reach the normal level, which will affect the effect of air conditioning and refrigeration. 5. The copper pipe between the outdoor unit and the indoor unit is too long: the ventilation pipe is too long, which will lead to low heat transfer efficiency and will also cause the air conditioner to not refrigerate.
