The sound of running water in the refrigerator is not a lack of fluorine. It is likely to be a normal phenomenon. This is the sound of the refrigerant flowing in the refrigerator refrigeration system. At this time, the refrigerant will convert between liquid and gaseous state. When it is liquid, it will gradually absorb heat and become gaseous state, resulting in the sound of water flow.
After the refrigerator has been used for a period of time, this and that phenomenon is likely to occur. The more common thing is to hear the sound of running water in the refrigerator. At this time, many people will doubt whether the refrigerator is broken or not due to lack of fluorine.
In fact, the sound of running water in the refrigerator is not a lack of fluorine. It is likely to be a normal phenomenon. It is the sound of the refrigerant flowing in the refrigerator refrigeration system. At this time, the sound heard is not very obvious or the refrigerator can be used normally, so don't worry.
The sound of running water indicates that the refrigerant is running in the pipeline, resulting in an echo. At this time, the refrigerant will convert between liquid and gaseous state. When it is liquid, it will gradually absorb heat in the evaporator, resulting in refrigeration effect. In this way, it will become gaseous state, resulting in the sound of water flow.
