Abstract
In a refrigerator, warm air is collected or drawn into a warm air return duct opening located at or near the top of the refrigerated space instead of the bottom. The warm air is passed through an evaporator where it cools. The cooled air is driven into a pressurized plenum located at the bottom of the refrigerated space. The plenum is defined by a screen extending across the bottom of the refrigerated space. Air in the plenum passes through holes in the screen and driven upward. The air flow inside the refrigerator is thus upwardly, i.e., from the bottom to the top.
