Abstract

In a refrigerator, many food boxes are stored, so the flow of chilly air has very complicate stream paths inside the room of a refrigerator. Moreover, on some occasions, there is no flow of chilly air in a space due to blocking flow paths by food boxes, which is an important issue to be settled for improving the ability of food storage with fresh states. One of methods to solve this problem is to redesign the flow-pattern of chilly air to be uniform flow inside room, if possible. In this work, we have tried to design the duct-structure for the uniform flow of a chilly air using a FE-analysis method. And we conducted real commercial tests using a refrigerator having the redesigned duct. The results showed that good agreements with general requirements.
