Which system employs compression pumps and condensers to facilitate cooling?

The mechanical compression system is the correct answer because it is specifically designed to use compression pumps, also known as compressors, along with condensers to achieve the cooling process. In this type of refrigeration system, the refrigerant is compressed, which raises its pressure and temperature. The hot, high-pressure refrigerant gas then flows into the condenser, where it releases heat to the surroundings and transforms into a liquid state. This liquid refrigerant subsequently enters the evaporator, absorbing heat from the environment and creating a cooling effect.

Mechanical compression systems are common in residential and commercial HVAC applications due to their efficiency and effectiveness in providing cooling. They rely on the refrigeration cycle, which involves the repeated compression and expansion of the refrigerant to facilitate heat transfer.

Other systems listed, such as cryogenic and thermoelectric systems, utilize different principles and technologies, while absorption systems rely on thermal energy rather than mechanical compression to drive the refrigeration cycle. These distinctions clarify why the mechanical compression system is the most suitable answer for the question.
