On which principle does a refrigeration system work?

Question

Accepted Answer

Refrigeration systems work on the principle of removing heat from a space to lower its temperature.

Refrigeration systems use a refrigerant to absorb and release heat through a cycle of compression and expansion.
The refrigerant absorbs heat from the space to be cooled, then releases it outside the space.
The cycle continues to maintain a lower temperature inside the space.
Examples of refrigeration systems include air conditioners, refrigerators, and freezers.

Accepted Answer

The Vapor Compression Refrigeration Cycle involves four components: compressor, condenser, expansion valve/throttle valve and evaporator. It is a compression process, whose aim is to raise the refrigerant pressure, as it flows from an evaporator. The high-pressure refrigerant flows through a condenser/heat exchanger before attaining the initial low pressure and going back to the evaporator.
