Which of the following are the main components of a refrigeration system?

The main components of a refrigeration system include the compressor, condenser, expansion device, and evaporator. Each of these components plays a crucial role in the refrigeration cycle.

The compressor is responsible for compressing the refrigerant gas, raising its pressure and temperature, which allows it to circulate through the system. The gas then moves to the condenser, where it releases heat to the surroundings and transforms into a high-pressure liquid.

Next, the liquid refrigerant passes through the expansion device, which reduces its pressure as it enters the evaporator. In the evaporator, the refrigerant absorbs heat from the environment, causing it to evaporate back into a gas and cooling the surrounding area.

Together, these components create a continuous cycle of compression, condensation, expansion, and evaporation, efficiently transferring heat and maintaining the desired cooling effect in refrigeration systems. While other options contain components found in HVAC systems or specific applications, they do not encompass the main components of a standard refrigeration cycle.
