A refrigerated display case comprising: a refrigerated display area; an air outlet and an air inlet opening into the display area and spaced from one another; a duct fluidically coupling the air inlet to the air outlet, the duct being configured to direct air flow out of the air outlet across the display area and toward the air inlet to form an air curtain across the display area; and an airflow inhibiting apparatus comprising: a conduit having an inlet and a plurality of outlet apertures, the outlet apertures arranged around a perimeter of an upper portion of an opening to the refrigerated display area; a fan fluidically connected to the conduit and configured to draw air into the conduit via the inlet and to discharge a jet of air from each of the plurality of outlet apertures; characterised in that: the outlet apertures are each angled outwards away from the display area such that the jet of air is angled outwards away from the display area to repel ambient air away from the display area so as to prevent airflow into the display area; and the inlet of the conduit is provided at a lower portion of the opening. a refrigerated display area; an air outlet and an air inlet opening into the display area and spaced from one another; a duct fluidically coupling the air inlet to the air outlet, the duct being configured to direct air flow out of the air outlet across the display area and toward the air inlet to form an air curtain across the display area; and an airflow inhibiting apparatus comprising: a conduit having an inlet and a plurality of outlet apertures, the outlet apertures arranged around a perimeter of an upper portion of an opening to the refrigerated display area; a fan fluidically connected to the conduit and configured to draw air into the conduit via the inlet and to discharge a jet of air from each of the plurality of outlet apertures; characterised in that: the outlet apertures are each angled outwards away from the display area such that the jet of air is angled outwards away from the display area to repel ambient air away from the display area so as to prevent airflow into the display area; and the inlet of the conduit is provided at a lower portion of the opening. a conduit having an inlet and a plurality of outlet apertures, the outlet apertures arranged around a perimeter of an upper portion of an opening to the refrigerated display area; a fan fluidically connected to the conduit and configured to draw air into the conduit via the inlet and to discharge a jet of air from each of the plurality of outlet apertures; characterised in that: the outlet apertures are each angled outwards away from the display area such that the jet of air is angled outwards away from the display area to repel ambient air away from the display area so as to prevent airflow into the display area; and the inlet of the conduit is provided at a lower portion of the opening. the outlet apertures are each angled outwards away from the display area such that the jet of air is angled outwards away from the display area to repel ambient air away from the display area so as to prevent airflow into the display area; and the inlet of the conduit is provided at a lower portion of the opening.
