Abstract
An open-type air defrost refrigerated display employing recirculatory refrigerated air flow for cooling, and reverse air flow into the ambient and from the ambient for defrost, there being a return air grille opening which is bioriented, with portions oriented to receive recirculatory cold air flow from across the display access opening during refrigeration, and portions oriented to discharge reverse flow defrost air into the ambient during defrost. These second portions are aerodynamically aligned with the adjacent passage from whence the reverse flow defrost air flows. The passage means preferably includes, between the refrigeration coil and the refrigerated air outlet, damper means for restricting the recirculatory refrigerated air flow a controlled amount, while allowing unrestricted reverse defrost air flow therethrough.
