  • Patent number: 5931013
    Abstract: A refrigerator display cabinet (10) for furnishing refrigerated goods has a vertical duct (20), which is surrounded by a magazine (24, 34) which is filled with the goods from above, and at its lower part is surrounded by a bottom (18), on which the goods rest and which at its periphery has an opening (38) for taking the goods out. A fan (12) is arranged to bring air which is refrigerated by a cooling element (22) to flow upwards through the duct (20) and then between goods located in the upper part of the magazine, from where the air flows downwards between goods located in the lower part of the magazine and out through holes (26) in the bottom and then back to the fan (12). Means (46) are arranged to reverse the circulation direction of the air from time to time so that the air periodically will flow in opposite direction through the display cabinet (10).
