Abstract:
1. An open-front refrigerated display case, having a medium temperature zone disposed above a low temperature zone in a generally vertically-stacked arrangement, comprising: a medium temperature-controlled space having a medium temperature air curtain arranged to flow across the open front of the medium temperature controlled space; a first fan configured to draw at least a portion of the air from the medium temperature air curtain through a first intake and across a medium temperature cooling coil and through a medium temperature flow path for discharge through a first outlet to maintain operation of the medium temperature air curtain; a low temperature-controlled space having a low temperature air curtain arranged to flow across the open front of the lower temperature-controlled space; a spillover airflow-diverting device disposed between the medium temperature zone and the low temperature zone, the spillover airflow-diverting device configured to direct spillover air from the medium temperature air curtain in a direction away from the open front of the low temperature zone; wherein the spillover airflow-diverting device comprises at least one louver configured to direct a gravity-induced flow of the spillover air in an outward direction away from the open front of the low temperature zone.
