refrigerator water filter

Are you curious about how a refrigerator water filter functions? In this guide, we’ll explore the essential workings of these filters. The refrigerator water filter connects the condenser to the capillary tube. Its main purpose is to absorb moisture and dust, keeping the refrigeration system clean and dry. The filter’s outer shell consists of red copper, with an inlet and outlet featuring different diameters. The inlet has a thick metal mesh, while the outlet has a finer mesh to effectively remove impurities.

Inside, the filter uses a molecular sieve to absorb moisture from the refrigerant, promoting smooth flow in the capillary tube and refrigeration system. Regular desiccant replacement is crucial, as saturation can lead to ineffectiveness. This guide will cover everything you need to know about refrigerator water filters, just keep reading~

Benefits of Using Refrigerator Water Filters

Improved Taste and Odor: By removing chlorine and other unpleasant substances, refrigerator water filters significantly enhance the taste and smell of drinking water. For tips on managing any lingering odors in your fridge, check out our guide on how to remove bad odor from the fridge.

Convenience: Having a direct line to filtered water through your refrigerator is not only convenient but also encourages healthy hydration habits.

Cost-Effective: Using filtered water can save money on bottled water purchases and reduce plastic waste

How Does Refrigerator Water Filter Work: Working Principle

As for how does refrigerator water filter works, it seems not very complicated. There will inevitably be trace amounts of moisture and tiny impurities in the refrigeration system, even though the whole system works in a dry vacuum environment. This is mainly because in the assembly process, due to the influence of the assembly environment, irregular assembly operations or incomplete cleaning of the parts themselves, air or some dust enters the refrigeration pipeline. The air contains a certain amount of moisture and impurities.

According to the refrigeration recycle principle, the overheated vapor with high temperature and pressure is discharged from the compressor discharge port, and after being cooled by the condenser, it enters the capillary tube for throttling and pressure reduction. Because the inner diameter of the capillary tube is very small, if moisture and impurities exist in the system, it is easy to cause blockage and make the refrigerant unable to circulate. They may accelerate the wear of pistons, cylinders, bearings, and other components if they enter the compressor, affecting the performance and service life of the compressor.

Therefore, it is necessary to install a filter drier between the condenser and the capillary tube. When the refrigerant flows through the filter, the contained moisture is adsorbed by the molecular sieve, and the dirt is blocked by the filter. Therefore, when we are replacing the filter drier during maintenance, we should be careful to avoid breaking the filter at both ends of the filter. The opened fridge filter should be used in time and can not be exposed to the air for a long time, otherwise, the molecular sieve inside may reach saturation and lose its role in adsorbing moisture.

How Does a Fridge Filter Work: Structure of Fridge Filter

A fridge filter removes impurities from water and ice. It uses several components to perform this task effectively.

First, the filter housing contains the filtration media. This is usually made of activated carbon, which absorbs contaminants like chlorine. The carbon has a large surface area, allowing it to trap more impurities.

Next, there is a sediment filter. This pre-filter captures larger particles, such as dirt and rust, preventing them from clogging the main filter. This step ensures that only clean water enters the activated carbon layer.

Some fridge filters also include additional stages, like reverse osmosis. This process uses a semi-permeable membrane to remove even smaller particles, including heavy metals and certain chemicals.

After filtration, the clean water is stored in a reservoir or dispensed directly for use. As you pour a glass of water or make ice, the filter works continuously to provide fresh, filtered water.

Things You Need to Know When You Are Using Refrigerator Water Filter

①Avoid cooling or heating of the fridge filter

If the refrigerator system is blocked, such as ice blockage and dirty blockage, frost can be seen at the capillary tube if it is blocked by ice. If it is dirty blockage, a large amount of refrigerant will be discharged after cutting. The filter drier is composed of a dryer and a filter installed in the liquid pipeline between the condenser outlet and the capillary inlet. When the filter is dirty, the filter drier will act as a capillary tube, and the refrigerant will evaporate at the filter in advance, resulting in a cooler surface or even a frost layer. In a refrigerator in normal use, under normal cooling conditions, the outer wall of the refrigerator cannot be seriously covered by curtains, bedding, newspapers, etc., if there is, please remove it as soon as possible; it should not be too close to the wall which may cause poor ventilation. In short, the refrigerator filter cannot be overheated when the refrigerator has not been repaired. Overheating will cause abnormal or poor cooling.

②Avoid blockage of the refrigerator water filter

If the ambient air is too poor and the quality of the air entering the air compressor is too poor, the compressed air of poor quality will cause great harm to the relevant parts of the air compressor, especially all kinds of filters, and if it is passed through degreasing If there are still many impurities in the compressed air of the steam filter, it is likely to cause clogging. In addition, if the air and oil filters fail and the work load of the degreasing vapor is greatly increased, the refrigerator filter is more likely to be clogged.
