A refrigeration case includes a housing having a top and a rear wall and defining an interior chamber, a door pivotably coupled to the housing opposite the rear wall and operable to selectively open and close the interior chamber, a first shelf positioned proximate a lower portion of the interior chamber, a second shelf positioned above the first shelf, a duct wall, a fan, and a diverter. The duct wall at least partially defines a flow channel extending between the first shelf and the second shelf. The duct wall includes a first opening above the first shelf and a second opening above the second shelf. The fan provides cool air flow and is in fluid communication with the flow channel. The diverter is positioned in the flow channel proximate the second shelf and directs air flow through the second opening and over the second shelf.

A cooler cabinet comprises: a storage compartment (130) for food or beverage products (130); a dispensing mechanism (143) for dispensing the food or beverage products (144) from the storage compartment without opening the storage compartment to ambient air; a water-retaining material (120) outside the storage compartment but in contact with it; an air channel (111) in contact with the water-retaining material; and means (114) for moving air through the air channel such that the air increases the rate of evaporation of water from the water-retaining material. It thereby withdraws heat from the water-retaining material and causes cooling of the interior of the cabinet, including the food or beverage products.

A refrigerated display case system includes a display case that defines an inner volume and a closed-circuit refrigeration system. The closed-circuit refrigeration system includes a condensing unit configured to sit on a top surface of the display case and including a compressor and a condenser assembly; a cooling coil and a fan configured to circulate an airflow from the inner volume through the cooling coil to cool the airflow; a liquid line coupled to an inlet of the cooling coil and to the condensing unit; and a rigid suction line coupled to an outlet of the cooling coil and to the condensing unit. The rigid suction line includes at least two bends between the outlet and the condensing unit and is configured to circulate a vapor phase of the refrigerant from the cooling coil to the condensing unit.

The present invention provides an open display refrigerator comprising: a refrigerated storage space, air in the refrigerated storage space being separated from air exterior to the open display refrigerator by an air curtain established by a fan which blows air towards an air outlet and which recovers air in the air curtain via an air inlet for recirculation to the air outlet; a wall bounding at least a part of the duct and the refrigerated storage space, the wall comprising one or more voids such that air in the duct can flow into the refrigerated storage space via the one or more voids; a deflector which, when the refrigerator is in use, interrupts at least a portion of the flow of air from the one or more voids and directs the portion of the flow of air towards the top of the refrigerator.

In a field-installable refrigerated merchandiser kit, a prefabricated refrigeration system module releasably and operatively connects to a separate cabinet module via mutual connection fittings to form a refrigerated merchandiser. The refrigerated merchandiser can have multiple refrigeration systems cooling a common refrigerated space inside the cabinet, each with an independent temperature controller. A refrigeration system can be disconnected from the cabinet only by separating releasable fasteners and disconnecting electrical plug-in connections. Each refrigeration system is prefabricated with integrated condensate removal. The refrigeration system mounts entirely above the top wall of the cabinet enabling deployment at zero offset from a backing structure. The refrigerated merchandiser can be deployed to occupy a footprint and have a ratio of shelf space volume to foot print greater than 3.25 ft.sup.3/ft.sup.2.

A multi-purpose retail display merchandising cavity is provided. An insulated case defines an internal product display area. The internal display area can be non-refrigerated and may only use a detachable fan cooling cartridge to maintain the ambient room temperature inside the internal product display area. Alternatively, the cavity can become refrigerated when a detachable refrigerated cooling cartridge is used to refrigerate the internal display area, thus allowing the cabinet to be easily and interchangeably used as either a dry goods cabinet for non-refrigerated goods or as a refrigerator for refrigerated goods.

A merchandiser including a case that has an air inlet and defines a product display area with a customer access opening. The merchandiser also includes a canopy that has a first air outlet and a second air outlet, a first passageway connecting the air inlet with the first air outlet to direct a first airflow through the first air outlet at least partially across the opening to define a primary air curtain, and a second passageway in fluid communication with a HVAC system by ducting coupled between the merchandiser and the HVAC system to direct a second airflow defining a secondary air curtain from the HVAC system through the second air outlet at least partially across the opening. The primary and secondary air curtains cooperate with each other to minimize infiltration of ambient air into the product display area.

Systems and methods relate to a temperature-controlled case. The temperature-controlled case includes a housing that defines a temperature-controlled space and an opening for providing user access to the temperature-controlled space. The case also includes a cooling element in thermal communication with the temperature-controlled space. The case further includes a modular plenum coupled to the housing and positioned behind the cooling element relative to the opening, wherein the modular plenum includes: at least one fan removably coupled to the modular plenum, wherein the at least one fan induces an air flow through the cooling element, and at least one electrical connector coupled to the modular plenum and positioned proximate each of the at least one fan for providing electrical power to each of the at least one fan.

A refrigerator appliance includes a cabinet with at least one shelf for displaying products, and a refrigeration system for cooling the cabinet. The at least one shelf includes a front edge located at a front of the cabinet, and an illumination strip extending parallel to the front edge and disposed at or near the front edge to illuminate products on the at least one shelf.

A method and system for dry aging the meat product uses a 12 volt DC powered portable unit comprising a plastic box configured for housing the primal cut of meat and placed inside a refrigeration system. The box is further equipped with an internal and external blower to control the air circulation and humidity respectively inside the box. A germicidal UV light disposed within the plenum in front of the internal blower to provide germicidal action on the dry aging meat product. A PCB controller placed on top of the box embedded with software and a humidistat to control the humidity inside the box and maintaining a closed micro environment to dry age the meat product with desired texture, flavor and tenderness.
