US 2022/0175154 A1 · DISPLAY REFRIGERATORS AND FREEZERS

Abstract

A display refrigerator or freezer comprises a refrigerated storage space. Air in the refrigerated storage space is separated from air exterior to the display refrigerator or freezer by an air curtain established by one or more fans which blow air towards one or more air outlets via a cooling heat exchanger and which recover air in the air curtain via one or more air inlets for recirculation to the one or more air outlets. The refrigerated storage space has a base shelf. One or more air inlet ducts are arranged between the one or more air inlets and the one or more fans such that the air recovered via the one or more air inlets is directed by the one or more air inlet ducts towards the one or more fans. The one or more air inlet ducts, in combination with at least a portion of the base shelf, define at least a portion of a cavity beneath the base shelf, the cavity being sealed from the air recovered via the one or more air inlet.
