In the cold winter, when we use air conditioning, there will be some minor problems, and many of these small problems do not know how to deal with them. One of them is the air conditioning icing, which is one of our most common situations. So we all know the reason ice conditioning do? Many people do not know why it! Today small just like we take a look Solution Cause and air conditioning icing icing it! Air conditioning icing reasons 1. Insufficient refrigerant. After a long period of use, the split type air conditioner may leak or leak refrigerant. When the refrigerant in the refrigeration system is reduced, the evaporation pressure is too low, causing the evaporator to freeze, and the location of the ice is generally in the front part of the evaporator. The elimination method is to first treat the leaking part, add the refrigerant, and the fault will be eliminated. 2. There are more refrigerants. Insufficient refrigerant will cause the air conditioner to freeze. Therefore, the air conditioner refrigerant will also cause the air conditioner to freeze. Some air conditioners re-inject the refrigerant due to displacement, leakage, etc., and the maintenance personnel improperly add more refrigerant. Excess refrigerant flows to the evaporator and partially evaporates and freezes. This type of ice is multi-junctioned around the rear part of the evaporator and around the compressor return pipe, and excess refrigerant is released, and the fault is eliminated. 3. The evaporator is too dirty. After the air conditioner is used for a period of time, the dust in the air or the microorganisms generated by the evaporator will accumulate on the evaporator, hindering the air circulation, causing the heat exchange to decrease, and the evaporator temperature to be too low to freeze. The icing position is in the rear part of the evaporator. After the ice is dissolved, flush the evaporator with water and brush with the soft brush along the fins. Be careful not to wet the electrical part. After cleaning, the fault is eliminated. 4. The thermostat fails. The temperature of the mechanical thermostat's temperature-sensing package changes with temperature, which drives the contact of the thermostat. Due to contact sticking, insufficient spring force, etc., the contacts are normally closed, and the air conditioner is continuously turned on, causing icing. Replace the thermostat and troubleshoot. 5. The temperature setting is too low. Some users set the air conditioner temperature too low, the air conditioner cooling rate can not keep up, the room temperature drops below the set temperature and start for a long time, or the downtime is very short, which will cause the evaporator to freeze. Some rooms have a very low temperature drop and can cause the evaporator temperature to freeze too low. This type of ice starts from the lower part of the evaporator. As long as the temperature is set higher, the fault can be eliminated. Air conditioning icing solution 1. Although there are many reasons for air conditioning icing, there are always solutions. Different icing conditions require different solutions. If the air conditioner is frozen due to the failure of the thermostat, then the thermostat of the air conditioner needs to be replaced. 2. If it is checked that the evaporator of the air conditioner is too dirty, then the air conditioner evaporator needs to be thoroughly cleaned. At the same time, it is necessary to pay attention to not being able to wet the electrical part; because the refrigerant is insufficient or excessive, the air conditioner freezes. It is necessary to exclude or add refrigerant. 3. If it is a malfunction of the compressor, it is better to replace the compressor of the air conditioner. 4. If there is a problem with the throttle valve, the filter of the internal machine can be cleaned to increase the operating temperature of the air conditioner, which can speed up the defrosting of the air conditioner. If we have such a situation in our own air conditioner, we can find the real reason for ourselves. The above is the reason why the air conditioner icing introduced by Xiaobian today and the solution for air conditioning icing are over here.
