Abstract
A cool air feeding system that senses a temperature of each part of a refrigerator compartment, compares the sensed temperature with a reference temperature, determines which part is to be cooled, and redistributes cool air to better cool a part of the refrigeration having a greater need to be cooled. Cool air redistribution is achieved using a single value having multiple openings. Such a valve can take the form of cylindrical manifold and a corresponding cylindrical, unitary-body flow distributor, for example.
