Which of the following is NOT considered a name for a flooded system?

A flooded system in refrigeration refers to a situation where the evaporator is fully charged with liquid refrigerant, allowing it to function correctly by providing efficient heat exchange. The terms associated with flooded systems often describe the mechanisms through which these systems operate.

Gravity refers to the natural force that can aid in the flow of refrigerant in a flooded system, particularly in using it to move liquid refrigerant to the evaporator. Thermosyphon describes a system using the principle of natural convection to circulate refrigerant, which is closely associated with the functioning of flooded systems. The term "percolator" can also be relevant in this context, as it suggests the flow and distribution of liquid.

In contrast, "overfeed" generally refers to a system design wherein more refrigerant is fed into the evaporator than can be vaporized, leading to potential inefficiencies or issues in performance. It does not align with the typical terminology associated with a flooded system. This distinction clarifies why overfeed is not considered a name for a flooded system.
