Midea air conditioner does not refrigerate and has a problem with voltage?

There are many reasons why the air conditioner is not refrigerated well, and the voltage problem is just one of the reasons. If the voltage is too low, the effective power of the compressor will not be reached, and the natural refrigeration efficiency will be reduced. It is recommended that you find a thermometer to check the outlet temperature of the air conditioner at different times, if it can reach below 16 degrees Celsius, it proves that the air conditioner is fine.

Whether the air conditioner is refrigerated or not depends on how many degrees you turn on, the temperature on the control panel is the shutdown temperature, and the air conditioner can be turned on normally at 22 degrees.

Check whether the outdoor unit is running, check whether the refrigerant pressure is normal, more than 4 kg.

Also, see if your room space matches the power of the air conditioner.

Voltage is the problem, you have to see if your wires are small, if the voltage is small, the wires are thin, the air conditioner can not start normally, if you turn off the household appliances at home, turn on an air conditioner, you see if it can work normally, you can't completely listen to the dealer, will not tell you the real reason for the hunger, your air conditioner may be a little lack of fluorine, you take a good look at it, and you have to see if the socket you plug in the air conditioner is really small, the air conditioner is not open when the power supply is less than 205V? , Xiao Zhu Q

If the voltage is low, the compressor will not work at all, because the press in the press is equipped with voltage protection, current protection, overload protection, overheat protection and many other protections.

If you drive it to 17 degrees Celsius, there is no cooling, is it a lack of fluorine, and whether the press is a string of gas?

You still have to find someone to see, the words of the air conditioner manufacturer are not credible. Yours doesn't seem to be a problem with voltage.

Relatedly, insufficient voltage may also cause the air conditioner to not be able to refrigerate.

1: Freon is not enough.

2: The voltage of the power supply is not enough.

3: The power of the air conditioner is not enough to not refrigerate.

4: The air conditioner is not refrigerated due to the high ambient temperature.

An air conditioner is an air conditioner, also known as an air conditioner. Refers to the process of adjusting and controlling parameters such as temperature, humidity, cleanliness, speed of ambient air in building structures by artificial means. Generally, it includes cold source heat source equipment, cold and hot medium transmission and distribution system, terminal device and other major parts and other auxiliary equipment.

It mainly includes pumps, fans and piping systems. The terminal device is responsible for using the cold and heat from the transmission and distribution to treat the air specifically to make the air parameters of the target environment meet the requirements.

The air conditioner compressor starts and the voltage is related, but other air conditioners can start the means that it is not a problem of voltage, that is, a little cold air means that the compressor can be started, it may be that the filter needs to be cleaned, or there is a lack of fluorine, if there is a lack of fluorine, it is not a point on the line, but also to check the leakage point and repair welding, so that the fluoride is added.

Low voltage will cause the compressor to not work, which is the reason for not refrigerating, or it may be a lack of air conditioning.

Find the power bureau to measure the voltage, and the voltage is fine, which means that it is a problem with the air conditioner.

Not cooling has a lot to do with voltage.

Maybe there's no more freon. The addition of a little fluoride may improve the situation.

The fixed-frequency and fixed-frequency air conditioner may be an external unit, the compressor capacitance is problematic, and the compressor starting capacitance capacity is low, which will support this situation. There is a phenomenon of open welding.

Car air conditioner does not refrigerate reason 1: lack of refrigerant Car air conditioner will generally add refrigerant once every 2 or 3 years, and some cars even have a very large head of the car owner in a year, and the refrigerant in the car has flew? Why do you want to add it frequently, doesn't the air conditioner have a sealing device, and according to the air conditioner, refrigeration is a physical reaction and does not need too much loss of refrigerant, why is it gone. Affair.

Midea air conditioners sometimes cool and sometimes don't, what's going on? I think Midea fans are sometimes cold here, sometimes not cold. Then it may be the reason why the motherboard is broken.

There are various reasons why an air conditioner does not refrigerate:

1. The air conditioning mode is set on ventilation.

2. The starting capacitor of the external compressor is broken.

3. The air-conditioning and refrigeration system lacks refrigerant (freon).

4. The tube temperature sensor of the evaporator of the internal machine is broken.

Turn the air conditioner for 30 minutes (the refrigerant is evenly distributed in the system), see whether the connecting pipe of the external unit is condensed or frosted, and whether the connecting pipe is cold with a hand mold.

It generally appears in Article 3. Even if the fluoride is not enough, professionals need to add fluoride.

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

1. Refrigerant leakage. (It is manifested that the internal and external units are working, and the compressor is also working, but it is ineffective).

2. The compressor capacitor is damaged or defective, resulting in the compressor not working. (The phenomenon is similar to the above, but the compressor does not rotate and overheats).

3. The resistance value of the temperature sensing head at room temperature changes, resulting in the air conditioner not working. (The phenomenon is the same as when the air conditioner stops at a set temperature).

4. Poor remote control or air conditioner receiver. (It is manifested as no response from the air conditioner when it is turned on, or it does not work from time to time).

5. Four-way valve (single chiller does not have this fault) or compressor high and low pressure string, air conditioning works but has no effect. (The phenomenon is the same as the first).

6. The control panel of the internal or external unit of the air conditioner is faulty, resulting in the air conditioner not being refrigerated. (Manifested as no reflection when turned on or the air conditioner is messy).

7. The zero live wire of the air conditioner power supply is reversed. (This failure occurs in a small number of air conditioners, usually at the time of installation).

8. The internal or external fan is damaged (the capacitor is more broken), and the external fan is damaged by the protection of high exhaust temperature or high voltage. If the internal fan is bad, the internal machine is frosty, the external unit has been working, and the internal machine has moisture into the device.

This is probably related to the location of your air conditioner, which is not cooled due to poor heat dissipation during the day.

Then you can clean the heat dissipation network of the outdoor unit, and also observe the condenser of the indoor unit, whether there is frost, if there is frost, it means that the refrigerant is not enough, and it should be added.

Analysis of the causes of non-refrigeration and solutions:

1. Whether the air-conditioning compressor is working normally, whether the fan is started, check whether the air-conditioning compressor, the starting capacitor and the fan are damaged, and check and eliminate.

2. Whether the air conditioner radiator is dirty and blocked, resulting in the air conditioner not being able to dissipate heat in time, causing the air conditioner to suddenly not refrigerate the fault, and the air conditioner radiator should be cleaned regularly.

3. Detect whether the air-conditioning system is deficient in fluoride and add fluoride to the air-conditioner in time. Check the method, turn on the machine first, after the compressor of the air conditioner runs continuously for 30 minutes, touch the condensing louver fan behind the air conditioner with your hands, if the temperature is not cool or hot, and the compressor is still working, it is likely to be fluorine leakage and lack of fluorine.

4. Check whether the temperature sensor of the air conditioner is damaged, whether the remote control and receiver are out of order, which are all reasons for the sudden failure of the air conditioner, please check and rule it out.

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

See if it's a problem with voltage or heat dissipation, and the new machine doesn't consider it bad.

There is a problem with the installation location or voltage.

1. Unstable voltage has an impact on air conditioning: It will cause the cold condenser fan and evaporator fan to fail to operate normally and the heat dissipation will be poor. If the clutch coil of the compressor is ignited due to insufficient voltage, there may be problems such as clutch slippage, overheating and burning due to insufficient torque.

2. Unstable compressor operationIf the air conditioner is turned on at low power and it can run the compressor, but the compressor operation is not stable at this time, because it needs a large voltage to support normal operation. It is advisable to turn off the air conditioner in time.

If it is forced to be turned on, the compressor may be damaged, resulting in the air conditioner being scrapped and unusable.

3. The refrigeration effect deterioratesWhen the voltage drops suddenly, the click power drops, resulting in poor cooling effect. If the air conditioner is abnormally in the refrigeration mode after long-term use, the operation of the refrigeration system in the air family mode will be damaged, and the refrigeration mode may not be used.

Therefore, once the voltage drops, it is necessary to turn off the air conditioner and repair it in time.

Compared with the fan, the refrigeration function of the air conditioner is not the fan, the fan makes people feel cool by blowing the air, but the air conditioner reduces the surrounding temperature through refrigeration, but many friends find that after the refrigeration is turned on, the refrigeration effect is not good, why is this? Today, let's take Midea air conditioning as an example, let's learn what is going on with the poor refrigeration effect of Midea's air conditioning.

Product model: Midea air conditioner KFR-26GW

1. Is the operation controller adjusted according to the requirements, and is the set temperature appropriate?

Please set the appropriate temperature, it is recommended to set the temperature when cooling: 26-28 degrees Celsius.

2. Is the dust filter dirty?

Please clean the filter in time and wash it once every 15 days.

3. Is there an obstacle in the air inlet and outlet?

Do not place items in the air inlet and outlet of the air conditioner, otherwise it will affect the cooling effect of the air conditioner, please remove foreign objects.

4. Is there other heat sources indoors, or is there a lot of people indoors?

The heat source will affect the effect of the air conditioner, please keep the heat source and the air conditioner at a certain distance.

5. Is the insulation effect of the room not good?

Due to the special wall structure of the room and the large heat loss, the effect is not good, but the air conditioner is actually running normally.

6. Does the air conditioner leak fluorine?

Fluoride leakage in the air conditioner will also cause poor refrigeration effect, so ask a professional to supplement freon at this time.

The above is today's sharing, sometimes the refrigeration effect is not good, it may not be the problem of the air conditioner itself, and everyone should also consider external factors.

Tips:

If you can't handle it yourself, get a professional to have it inspected and repaired to avoid more damage.

This article is based on the Midea air conditioner KFR-26GW brand.

The dehumidification of the air conditioner is used normally, but the refrigeration cannot be operated normally for the following reasons:

1.Refrigerant leakage: Refrigerant is an important element that compresses and expands the air-conditioning system to complete the cooling or heating effect. If the refrigerant leaks, it will affect the refrigeration effect, and it is necessary to find a professional technician to check.

2.Compressor failure: The compressor of the air conditioner is the heart of the air conditioning system, which generates the pressure and temperature to the circulation of the refrigerant to make the indoor temperature drop. When the compressor has a combustion barrier, the refrigeration effect will be reduced or the refrigeration will be stopped completely.

3.Circuit failure or controller failure: Air conditioning refrigeration also needs to rely on the circuit and the good virtual controller to adjust, if there is a circuit or controller failure, it will cause the air conditioner to fail to cool normally.

For the reasons mentioned above, it is necessary to find a professional maintenance personnel for inspection and repair.

(1) Fluorine leakage at the connecting pipe joint;

2) The wiring is incorrect;

3), fuse burning;

4) The compressor is faulty;

5) The external environment temperature is high, and the indoor personnel are more than the United States, and the air conditioner is working at full load.

6) The power supply voltage is too low, which causes the Midea air conditioner to be difficult to start, and then stops or the fuse blows after starting, so it is recommended that the user install a power regulator.

7) The air outlet of the air outlet is not large when the temperature does not drop in the strong cold room, which is because the air filter has too much dust, and the filter is cleaned.

8) Improper adjustment of the thermostat.
