Abstract
An air defrost reach-in refrigerated display case employing aerodynamic isolation of the coil from the product storage and display space during defrost. The fans and refrigeration coil are in a chamber separated from the display space, there being restricted flow flues between this chamber and the display space. Ambient air inlet and discharge ports astraddle the coil and fans, and between the cabinet exterior and this chamber enables short circuit flow of ambient defrosting air through the ports for defrosting of the coil when doors on the ports are open, without significant flow into the storage and display space.
