Kelon air conditioning and refrigeration

There are many reasons for not refrigerating, and the most common reason is that the compressor protection device trips out and does not refrigerate.

Compressor overload protection will trip, which means that the high-pressure pressure of the system is too high, and the overheating current is too large. It could also be a problem with the circuitry.

Causes and elimination of high pressure and overheating of the refrigerant system

1. Too much refrigerant. Reduce the refrigeration dose appropriately.

2. Poor heat dissipation. Check the condenser pipe for dirt and dirt and clean the condenser.

3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned.

5. Fluoride deficiency is also possible. When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

The electrical problem is:

1. Control circuit board failure.

2. The temperature sensor is overloaded and the information is wrong.

3. The power supply wiring is loose and the contact is poor.

4. The starting capacitor or compressor starting coil is burned out.

There are many possible causes, and it is necessary for professionals to conduct detailed analysis and judgment in order to know exactly the reason for not refrigerating.

Don't buy Kelon's air conditioner, we are engaged in activities here, I got one, the result is now a high temperature day, the air conditioner inside is regarded as an electric fan cooling effect is not generally poor. We have no after-sales service in a small county, so don't buy Kelon's.

I feel the same way, don't use it anymore I can return it and hurry up Damn, I regret it Now in the middle of the night, I listen to the noise of the air conditioner I have adjusted it to 24 degrees I don't have to cover the quilt to sleep I'm so strong.

The square 35 machine can barely be used, which is not too small.

2. It may be that the indoor sealing is not good, and hot air comes in.

3. The biggest possibility is that there is a problem with the refrigeration effect of the air conditioner, or the air conditioner is not well installed, and the internal refrigerant has leaked.

4. You can let Kelon's after-sales service test whether the refrigerant is leaking, if the system pressure is less than 4MPa, then it is caused by the lack of refrigerant.

Hello, the heating of air conditioning depends on the temperature difference between the air inlet and the air outlet, and the national standard is a temperature difference of 16 degrees! air inlet (do not turn on the air conditioner temperature); The air outlet (the thermometer is placed on the air conditioner swing blade), the larger the temperature contrast temperature difference detected, the better the effect. There is also a human body temperature of 37 degrees, when the outdoor temperature is below zero, it is recommended to choose a stroke or low wind speed!

It's better to feel like this.
