What is the basic work of refrigerant compressor inside the refrigerator?

The refrigerant compressor is often called the heart of the refrigerator. Its basic job is to compress and circulate the refrigerant throughout the cooling system.

Its main functions are:

1. Compresses low-pressure refrigerant gas coming from the evaporator.
2. Raises the refrigerant’s pressure and temperature, turning it into a hot, high-pressure gas.
3. Pumps the refrigerant to the condenser, where it releases heat to the outside air.
4. Maintains refrigerant circulation through the condenser, capillary tube, and evaporator.
5. Enables cooling by keeping the refrigeration cycle running continuously.

In simple terms:

• The compressor pumps the refrigerant.
• The condenser releases heat.
• The capillary tube reduces the refrigerant pressure.
• The evaporator absorbs heat from inside the fridge, making it cold.

Without the compressor, the refrigerant cannot circulate, and the refrigerator will not cool. That’s why the compressor is considered the most important component in a refrigerator’s cooling system.
