What role does the compressor play in a refrigeration cycle?

The compressor is a crucial component in a refrigeration cycle primarily because it facilitates the continuous circulation of the refrigerant through the system. By compressing the refrigerant, the compressor increases its pressure and temperature, allowing it to move from the evaporator, where it absorbs heat from the environment, to the condenser, where it releases this heat. This cycling process is essential for maintaining the functionality of the refrigeration system, as it enables the refrigerant to absorb and release heat effectively, thereby providing cooling.

This role of cycling the refrigerant is fundamental to the overall operation of the refrigeration cycle, ensuring that heat is transferred efficiently and the desired cooling effect is achieved. Other components like the evaporator and condenser have specific roles, but without the compressor, the refrigerant would not circulate, and the system would be inoperative.
