What is a refrigerator block? Working principle & function of refrigerator block

Refrigerator block is a component that plays a very important role in the structure of the refrigerator. But do you know what a refrigerator block is? What is the working principle and function of the refrigerator block? Let’s find out the following information with lassho.edu.vn!

What is a refrigerator block?

Refrigerator block is a specialized term to refer to the compressor in the refrigerator. Block is designed and placed at the back of the refrigerator.

Block is an extremely important part of deciding whether the foods in your family’s refrigerator are fresh or not when they create cold air to preserve the best food.

The refrigerator block also has another function of compressing gas in a cycle from the outdoor unit to the indoor unit to do other tasks such as freezing and cooling the inside of the refrigerator.

When standing near the refrigerator, you will feel the wind blowing out hot and dry, which explains the cooling action of the refrigerator block.

Types of current refrigerator blocks

Currently on the market, there are many different types of refrigerator blocks. But there are mainly 3 types of Block that are being used most by customers today:

• Spiral block.
• Swing block.
• Piston bolt.

The spiral blocks used in most refrigerators today are easy to see, because this block type offers superior efficiency compared to other block types.

Working principle of refrigerator block

Refrigerator block works in two processes: the process of sucking the cold-forming solvent and the process of compressing the air.

Solvent extraction process:

• The piston in the body of the refrigerator block works according to the left-to-right system, which will cause the volume in the cylinder containing the piston to increase, and at the same time make the pressure inside the block decrease rapidly.
• When the pressure in the suction chamber is greater than the cylinder pressure, the suction valve will open and begin the process of drawing solvent into the cylinder chamber. This process will work continuously and stop only when the piston moves to the end point.

Compression process:

• After the piston process has stopped at the end point, this is also the time when the solvent is fully absorbed in the cylinder. This will reduce the volume in the cylinder.
• When the pressure in the cylinder at this time begins to increase until it is greater than the pressure in the cavity, the valve tube will be opened, the compressed solvent will be brought into the condenser.

Block works continuously like that and plays an extremely important role in the entire operation of the refrigerator.

The function and role of the refrigerator block

Function of the refrigerator block

Refrigerator block is the part used to circulate refrigerant in the conduit system from indoor unit to outdoor unit and vice versa, so the block has the following functions:

• The refrigerant in the indoor unit will be continuously sucked and compressed at high pressure. With the process of changing solvents from gas to liquid. While converting, it will directly produce high temperature and be blown to the outside through the outdoor unit. This is the phenomenon that when you stand near the hot air conditioner, you will feel the wind.
• When the room temperature has not reached the required level. The block will work to create rotation in the pipeline. This will help the process of discharging the heat of the outdoor unit and collecting the heat of the indoor unit to operate smoothly.

The role of the refrigerator block

• The refrigerator block will absorb the refrigerants in the evaporator
• The refrigerator block will maintain the pressure so that the solvent evaporation process always takes place at the lowest temperature.
• In order for the condenser to operate normally, the block will compress the cold vapor to condense the pressure.

That is why the refrigerator block plays an important role as the heart of the refrigerator. If the refrigerator block is weak, it will cause the refrigerator to be not cold or cold. Therefore, if you see that your refrigerator block has a problem, you need to report it to a mechanic to repair it in time.

Hopefully the above article will help you understand more about what a refrigerator block is, the operating principle and important function of the refrigerator block. Any questions please leave a comment below!
