Abstract

Method of defrosting cooling elements in a display box for chilled items, which has a channel for air that is forced by fans to circulate around an article store, through cooling elements in the channel and on an open side of the warehouse of articles, characterized in that in the thawing the cooling elements are disconnected and the air in the channels is forced by the fans to flow in a direction opposite to their direction of flow during normal operation, the air being cooled by the cooling elements forced by guides to leave the circulation path in a direction away from the articles, and because air from the environment is introduced in the place or places where the air was expelled before.
