Does any refrigerator need a filter dryer?

The first one will cause liquid refrigerant to enter the compressor.

You should know that the installation position of the filter drier is after the evaporator. Evaporation will vaporize the liquid refrigerant, but there may be incomplete evaporation. At this time, not only a gas-liquid separator, but also a filter drier is needed. To dry the refrigerant.

Second, it will cause too much residue in the refrigerant.

The refrigerant runs normally in the refrigerator. To be honest, some residues, such as metal waste, some waste of lubricating oil, or various other residues, will inevitably lead to residues in the refrigerant if there is no filter device. The refrigerant enters the circulation system together, causing damage to various components (especially the compressor), and the cooling efficiency of the refrigerant itself decreases, which ultimately leads to a decrease in the overall cooling effect of the refrigerator.

Third, the filter drier can avoid excessive moisture in the refrigerant.

If the refrigerant contains moisture, it will cause liquid shock in the compressor after entering the compressor. Therefore, a filter drier should be installed to avoid excessive moisture in the refrigerant.

The above three points are the reasons why the filter drier must be used in the refrigerator. In any refrigerator system, a filter drier is required. In addition, it is very important that the filter drier in the refrigerator system needs to be maintained regularly.
