What is the primary function of the compressor in a refrigeration system?

The primary function of the compressor in a refrigeration system is to compress vapor refrigerant and increase its pressure. This process is essential because it allows the refrigerant to move through the system and facilitates the heat exchange processes that are critical to refrigeration.

When the refrigerant vapor enters the compressor at a low pressure, the compressor compresses it, resulting in a higher pressure and temperature. This transformation is vital for the subsequent stages of the refrigeration cycle, such as the heat rejection that occurs in the condenser. Without the compression process, the refrigerant would not be able to adequately dissipate heat, which is necessary to create a cooling effect in the system.

The compressor plays a crucial role in maintaining the continuous circulation of refrigerant, ensuring that heat is absorbed from the space to be cooled and expelled outside, thereby enabling the cooling cycle to function efficiently.
