ABSTRACT:
A refrigerated display chest with an open top has an air circulation channel to enable flow of air in one direction for a cooling cycle, and reverse flow for a defrosting cycle. A diversion channel is provided at the front of the chest, to direct exhaust air away from the chest, during defrosting cycles, so as to avoid interference with external air drawn into the chest at this time.
