We sometimes find that the refrigerator water filter generates heat. Is this ice phenomenon normal?


The answer is abnormal. This phenomenon may be caused by insufficient heat dissipation of the condenser (such as high outside temperature, insufficient condenser replacement area, excessively broken capillary tubes, removing the left and right condensers, adding too much refrigerant, etc.), which can be super-filtered in the refrigerator. The device is very hot and does not dissipate heat well.

Refrigerator filters the impurities in the refrigerant, such as oxides, dust and sand. Dirt such as metal chips makes the refrigeration cycle work normally. If the filter is equipped with a desiccant, it can also absorb the remaining moisture in the refrigeration system, prevent ice blockage, and prevent water from corroding equipment and pipes. The 4396841 refrigerator filter must have a larger filtering area to avoid pressure loss. It is generally better to install 2~3 layers of copper wire filter in the front. The new gauze is almost unusable. The use of cotton is strictly prohibited. Blockage affects the refrigeration cycle and increases compressor load and noise.


One of the functions of the filter drier is to filter out debris in the refrigeration system, such as metal chips, various oxides and dust, etc., to prevent debris from clogging the capillary tube or damaging the compressor. These impurities come from incomplete parts cleaning and inconsistent assembly processes, causing external impurities to enter the refrigeration pipeline or the water, air or acidic substances in the system to produce chemical reactions. These impurities-once entering the compressor, pistons, cylinders, bearings, etc. may be severely worn or even stuck; when the motor windings enter the terminals, they may damage the winding coil insulation. Short circuit, breakdown; entering the capillary, because the inner diameter of the capillary is small, it is easy to cause blockage without cooling, so it is very necessary to filter out these impurities.
