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

In a refrigeration system, one primary function of a compressor is to provide differential pressure to circulate refrigerant. The compressor plays a crucial role in the refrigeration cycle by compressing the refrigerant gas, which increases its pressure and temperature. This process allows the refrigerant to move through the system, transitioning from low-pressure areas to high-pressure areas.

By increasing the pressure, the compressor also facilitates the flow of the refrigerant to the condenser, where it releases heat to its surroundings and changes state from a gas to a liquid. The differential pressure created by the compressor is essential for ensuring that the refrigerant can effectively cycle through various components, such as the evaporator and condenser, allowing for heat exchange to occur.

While the other options mention important processes or functions, they do not capture the primary role of a compressor in ensuring the efficient circulation of refrigerant within the overall refrigeration system.
