What is a refrigerator filter? Structure and working principle

Using the refrigerator for a long time, surely many people still do not know the refrigerator filter. They play an important role in the whole system to help the refrigerator operate stably and smoothly. Please follow the article below for more information about refrigerator filters.

What is a refrigerator filter?

It can be said that the refrigerator filter is considered one of the most important components in the system of the refrigerator. They have the role of removing mechanical residues, chemical substances such as water, acids, … out of the refrigerant cycle.

Structure of the refrigerator filter

The refrigerator filter has a fairly simple structure:

• Mesh filter: Has the same design as a normal filter, used to filter impurities harmful to the refrigerator system to the outside environment.
• Warming agent (cold gas filter stone): Used to absorb all moisture, impurities that are potentially harmful to the refrigerator system in places with low temperatures.

Currently, on the market, there are many types of refrigerator gas filter stones with different structures, functions and specific characteristics suitable for many refrigerator lines such as: Acid filter stone, moisture filter stone, moisture filter stone combined. with acids,…

This gas filter stone can be fixed in one place or can be flexibly moved in the filter to help absorb moisture faster .

How does a refrigerator filter work?

In general, refrigerator filters have a simple structure, but their operating principle is quite complicated, here is how the filter works:

When the refrigerant of the refrigerator condenses , it must pass through 2 layers of mesh inside the dehumidifying bag to enter the filter. At this time, the wet and dusty impurities will be removed by the system.

When the refrigerator is operating, when it passes through the filter, the mesh has removed a relative amount of moisture, including impurities stuck inside the refrigerant. If this refrigerant is not filtered, it will cause a lot of damage to the cyclone and valve parts.

If the refrigerant is damaged, the repair costs are very expensive. Therefore, always make sure the refrigerant is always in a cooled state and filter out the dust and do not let them enter the refrigerator system.

However, after a long time of operation, the function of the filter film will gradually decrease. Impurities because they are not filtered , but densely covered, make the filter clogged . At the same time, when using the lips will not be cleaned, it will move to other parts, causing blockage .

Since then, the refrigeration blocks are damaged , around the indoor unit, there is a freezing situation or the cold valve is gradually opened, causing the gas to be diluted. If this situation is prolonged, the local system of the refrigerator is very prone to error problems, the possibility of damage is very high.

Therefore, to ensure that the filter is always operating stably, you need to regularly maintain and periodically check the entire refrigerator to promptly detect replacement and repair.

Function of the refrigerator filter

The main function of the refrigerator filter:

• The filter helps to limit moisture blockage in the capillary tube in the refrigerator.
• Performs the function of removing and filtering dirty impurities .
• Prevent the lubricating oil from disappearing.
• In addition, there is also the task of dehumidifying the system .

Some notes to help the refrigerator filter be used longer

Here are some notes to help the filter use longer, longer life:

• In order to ensure the filter works stably and effectively, you need to regularly check and maintain it periodically to promptly detect errors for repair and replacement.
• At the same time, regularly check other parts of the refrigerator to promptly detect and fix errors as quickly as possible.
• If the filter undergoes many repairs as well as damage and is too severe, you should replace it with a new one to ensure better cabinet operation.
