ABSTRACT:
An open well type refrigerated display case for low temperature application having reverse flow of refrigerated air access the access opening in the top of the display case to produce the lowest temperatures toward the front of the display case. Multiple horizontal air bands are circulated across the opening provided in the top of the display case to dissipate radiant heat impinging on the product displayed in the case, with the inner air band being refrigerated and the outer air band being partially refrigerated and dehumidified. Dehumidification of the outer air band is achieved by aluminum fins provided in a lower portion of the duct work which conducts the outer air band.
