A refrigerated display case comprising: a refrigerated display area; a door configured to close an opening to the refrigerated display area; an air outlet spaced apart from an air inlet; a duct fluidically coupling the air inlet to the air outlet and configured to direct air flow out of the air outlet across the display area and toward the air inlet forming an air curtain across the display area; and an airflow inhibiting apparatus comprising: a conduit having an inlet and a plurality of outlet apertures arranged around a perimeter of the opening; a fan 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, the plurality of outlet apertures angled to repel ambient air away from the display area when the door is opened preventing airflow into the display area.

A bracket for clamping an aerofoil to a shelf of a refrigerator is described. The bracket comprises a mounting portion for holding part of an aerofoil in use, an upper jaw configured to engage the forward lip of shelf and a lower jaw member configured to engage a lower lip on the underside of refrigerator shelf. The bracket may also comprise clamping means configured to enable the upper jaw member and the lower jaw members to be drawn towards one another to clamp the bracket on the refrigerator shelf.

A sanitizer has substrates which are coated with an optically-activated nanomaterial TiO2 coating for cleaning air which comes into contact with the surfaces of the coating. UV LED light sources are arranged to emit light to be incident on the surfaces to activate the coatings. There is a large surface for impingement of air on the coatings due to a grille arrangement of the substrates, and the LED-emitted UV light being incident at acute angles on the grille honeycomb structure.

For effective and energy-saving cooling of articles using straightforward designs, a refrigeration unit, in particular a refrigerated cabinet, freezer cabinet, refrigerated island or refrigerated counter, for storing and/or displaying articles, having a refrigeration chamber for the articles, and having a channel, which is assigned to the refrigeration chamber and is intended for supplying air, wherein two air flows can flow out of an outlet of the channel at different flow speeds and form a double protective air curtain in front of an access to the refrigeration chamber, is configured so that the channel has an element which acts on the supplied air so that the supplied air is divided up into the two air flows with different flow speeds by the element.

A refrigerated merchandiser includes a case having a lower wall, an upper wall, a rear wall, and a rear panel. A product support area is at least partially defined by the lower wall, the upper wall, and the rear panel. A first air passageway is formed in the case for supplying refrigerated air to the product support area. A fan is positioned in the first air passageway for creating airflow. An evaporator coil is disposed in the air passageway to condition the airflow. A duct is coupled to the rear panel to create a second air passageway.

A temperature controlled case includes a housing that defines a temperature controlled space and a multi-circuit cooling element in thermal communication with the temperature controlled space. The multi-circuit cooling element includes two or more cooling coils. Each of the cooling coils is coupled to a different circuit structured to selectively circulate coolant through the multi-circuit cooling element. Each circuit is fluidly separate from each remaining circuit such that the coolant circulated through each circuit is not shared with each remaining circuit. The multi-circuit cooling element further includes a plurality of heat exchange fins coupled to each of the two or more cooling coils such that each of the heat exchange fins facilitates heat removal from the temperature controlled space by each of the two or more cooling coils.

A ducted shelf for an open-fronted display unit employing air curtains. The shelf has a supply duct at a lower level communicating with a downwardly-facing forward discharge outlet and a return duct at an upper level communicating with an upwardly-facing forward return inlet. In front-to-back section through the shelf, a forward supply duct extension in front of the supply duct narrows forwardly above the discharge outlet and a forward return duct extension in front of the return duct reaches downwardly to the lower level of the shelf to lie forwardly of the supply duct. This beneficially reduces the thickness of the front of the shelf.

A refrigeration system having a refrigerant circuit including a condenser, a flow control device, an evaporator, and a compressor connected in series. The compressor is configured to circulate a cooling fluid through the refrigerant circuit. The refrigerant circuit has an inlet line fluidly connecting the condenser to the evaporator and a suction line fluidly connecting the evaporator to the compressor. A heater is positioned to heat the cooling fluid during a defrost mode, and a pressure control is coupled to the refrigerant circuit downstream of the evaporator. In the defrost mode, the pressure control apparatus is configured to increase system pressure during the defrost mode to maintain flow of refrigerant into the evaporator and to control flow of cooling fluid to the compressor.

A refrigerated case includes a case body including a top panel, a rear panel, and a bottom that cooperate to define a display space, a portion of a refrigeration system disposed in the case and operable to cool a flow of air, and a first air passage positioned to direct the flow of air near the top panel from the rear panel generally toward a front of the case. A one piece holder is positioned to receive the flow of air adjacent the front of the case, the one piece holder formed as a unitary component using a PVC foam material and arranged to accelerate and redirect the flow of air in a downward direction toward the bottom, and a filter member is at least partially supported by the holder and positioned to receive the flow of air in the downward direction and to redirect that flow into the display space.

A showcase includes: a casing having a front opening through which a product is picked up; a product storage located in the casing and including a shelf on which the product is displayed; a first airflow generator that sends air for a first air curtain to flow outside along the product storage; a second airflow generator that sends air for a second air curtain to flow outside along the first air curtain; and a controller that causes the first airflow generator to operate and causes the second airflow generator to reduce an output of the second airflow generator from an output at a first timing, upon arrival of a second timing when a break of the second air curtain due to disturbance is greater than a break of the second air curtain at the first timing.
