Title: Showcase
Inventor: YAMAMOTO KAZUYUKI
IPC: F25D21/04
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a showcase to perform proper prevention of condensation on the surface of a transparent door. SOLUTION: A showcase is formed such that an evaporator 6 is arranged at an inner upper part of a cold insulation chamber 1, and since the air for cooling which has been heat-exchanged by the evaporator 6 is circulated from the back side of the interior of the cold insulation chamber 1 through the front side, cold air right after heat-exchange is prevented from making contact with the back of the glass plate of a transparent door 3.  Namely, since comparatively warm air deprived of a cold heat by refrigerated or frozen goods is brought into contact with the back of the glass plate of the transparent door 3, even under high outside air temperature and humidity environment, by reducing a temperature difference between the surface side (outside air) of the glass plate and the back side (the cold insulation chamber), condensation on the surface of the glass plate is prevented from occurring.
