How does a compressor function within a refrigeration system?

The function of a compressor in a refrigeration system is to compress refrigerant gas, which significantly raises its pressure and temperature. This is a critical step in the refrigeration cycle.

Once the refrigerant gas enters the compressor, it is subjected to mechanical energy, which forces the refrigerant into a smaller volume. As the gas is compressed, its pressure increases, making it capable of moving through the system into the condenser. The high-pressure gas is then expelled from the compressor and flows into the condenser, where it will ultimately lose heat and condense back into a liquid state.

Understanding this function is vital, as the compressor plays a pivotal role in maintaining the flow and effectiveness of the refrigeration cycle by enabling the refrigerant to absorb heat in the evaporator and release it in the condenser. This sequential process is what allows refrigeration systems to cool areas or preserve food items effectively.
