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

The primary purpose of the compressor in a refrigeration system is to compress refrigerant gas from a low-pressure to a high-pressure state. This process is crucial because it allows the refrigerant to change its phase and absorb heat from the environment.

When the refrigerant is at a low-pressure state, it can efficiently absorb heat from the space being cooled. The compressor increases the pressure of this gas, which raises its temperature as well, allowing it to release heat effectively in the condenser when it transitions into a liquid state. The increase in pressure also ensures that the refrigerant can flow through the system, moving to the evaporator to absorb more heat.

Understanding the role of the compressor highlights its importance in the refrigeration cycle, where it acts as the heart of the system, driving the circulation of the refrigerant and facilitating the heat exchange process essential for achieving refrigeration.
