In a vapor-cycle cooling system, what happens at the compressor stage?

In a vapor-cycle cooling system, the primary function of the compressor is to increase the pressure of the refrigerant. When the refrigerant, typically in a gaseous state, enters the compressor, it is compressed, which raises its pressure significantly. As the refrigerant is compressed, its temperature also increases due to the principles of thermodynamics, specifically the ideal gas law.

This pressure build-up is crucial because it allows the refrigerant to flow through the system and carry heat away from the cabin or area being cooled. When the high-pressure refrigerant exits the compressor, it then flows into the condenser where it will eventually release heat to the external environment. Understanding the compressor's role in building pressure is fundamental for comprehending the overall function of the vapor-cycle cooling system.
