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

The primary function of a compressor in a refrigeration system is to increase the pressure of the refrigerant vapor and move it through the system. This process is essential for the refrigeration cycle, which operates through the transformation and circulation of refrigerant.

When the compressor takes in low-pressure vapor from the evaporator, it compresses this vapor, significantly raising both its pressure and temperature. This increased pressure and temperature allow the refrigerant to flow to the condenser, where it will release heat and change into a liquid state. The ability of the compressor to effectively move the refrigerant is crucial for maintaining the flow and efficiency of the entire system, ensuring that the refrigerant can absorb heat in the evaporator and reject it in the condenser.

Understanding the compressor's role highlights its importance in facilitating the continuous cycle of refrigerant, and how it supports the overall cooling process by ensuring that the refrigerant is adequately pressurized for optimal thermal exchange.
