Abstract

Improved device in a display box for chilled items and having an air channel, which extends around the article store and on items in the opening of the box, with fans and cooling elements in the channel, to perform the the method according to claim 1, characterized in that the box has means for reversing the direction of air flow and because guides are provided in the opening of the channel into which air is introduced during normal operation, directing the guides in defrosting and unloading. Of the air from the channel to the flow of air out of the circulation path and in the sense of moving away from the articles in the box, with the atmosphere being outside the box.
