Disclosed is a system for real-time measurement of inventory on shelves. The system uses light sensors placed in association with the inventory and the shelves to measure in real-time the removal/replacement of inventory from the shelves. When inventory is on the shelves, less light reaches the light sensors. As inventory is removed from shelves, the light sensors receive more light. The difference in light received generates as signal that can be measured, thereby allowing for determining inventory levels on each shelf. The system may be retro-fitted to existing shelving systems, thereby avoiding the cost of purchasing new shelving systems. The system can work on any shelving system, including gravity-feed roller shelf (GRS), flat shelves, and spring loaded pusher shelves, and is unaffected by usual temperatures found in retail establishments and can thus work in both refrigerated and unrefrigerated systems. Also disclosed are related methods.

A refrigerator includes a cabinet, a door configured to open/close the cabinet, an outer plate defining a front surface of the door and having an opening formed therein to pass through the door, a door liner defining a rear surface of the door, lighting members configured to illuminate storage spaces of the door and the cabinet, a transparent panel assembly mounted to shield the opening and allowing the storage spaces to be selectively seen according to an ON/OFF state of the lighting members, an insulator filled between the outer plate and the door liner, and a blocking part arranged inside the door along a periphery of the transparent panel assembly and detachably coupled to a peripheral surface of the transparent panel assembly to fix the transparent panel assembly.

A display includes at least one revolving door panel hinged to a box frame by means of a hinging means actuated by an actuation means The display has a movement component that can be coupled with the door panel to move the door panel, as well as a fast coupling/uncoupling means for the fast coupling of the movement component with the door panel to actuate the door panel by means of the actuation means, and permit the fast uncoupling of the movement component from the door panel to move the door panel manually, independently from the actuation means.

An air cooling system for a temperature-controlled display case includes at least two modular cooling elements, one or more fans configured to provide an air flow to the at least two modular cooling elements, and an air plenum common to each of the one or more fans and the at least two modular cooling elements, the air plenum being configured to direct the air flow from the one or more fans through the at least two modular cooling elements and into a product area of the temperature-controlled display case.

An aircraft passenger service device for receiving goods for cold storage to be supplied to aircraft passengers includes a receiving device having a viewing apparatus, a coolant inlet for feeding a coolant into the receiving device, and a coolant outlet for discharging the coolant from the receiving device. The viewing apparatus is designed to enable a user to inspect goods stored in the receiving device before removal. The aircraft passenger service device further includes a cooling arrangement having a coolant circuit line connected to the coolant inlet and the coolant outlet of the receiving device, and a device that directs into the coolant circuit line a refrigerant fluid flowing through a refrigerant fluid circuit line of a central cooling system of the aircraft.

A refrigerated display case having a bottom assembly with lower lateral edges, a top assembly with upper lateral edges, a rear wall assembly and side walls; a cooling chamber at the bottom assembly; and lower securing elements in a lower region of the sidewalls and upper securing elements in an upper region of the sidewalls. The lower lateral edges of the bottom assembly near the side walls are provided with securing elements adapted to interact with lower counterpart securing elements and the upper lateral edges of the top assembly near the side walls are provided with upper counterpart securing elements, the side walls being detachably secured to the refrigerated display case by connecting the lower securing elements to the lower counterpart securing elements and by connecting the upper securing elements to the upper counterpart securing elements.

A liquid system for circulating a liquid through a circulation loop includes a liquid pump, a primary liquid reservoir and an auxiliary liquid reservoir. The liquid pump pressurizes liquid within the circulation loop. The primary liquid reservoir has a primary variable volume expandable to accommodate volumetric expansion of pressurized liquid up to a threshold volume. The auxiliary liquid reservoir has an auxiliary variable volume expandable only after the threshold volume is exceeded up to a maximum volume.

A food prep table may include an upper chilling zone and a lower chilling zone, with each chilling zone containing an evaporation coil system, such as a TurboCoil™ system. The two evaporation coil systems are monitored and controlled by a dual thermostat and control unit (500) having temperature sensor probes in each chilling zone and controlling solenoid valves within each evaporation coil system. By the artful use and implementation of the dual thermostat and control unit, and by the artful use of T junctures in refrigerant supply and return lines, the disclosed embodiments enable a single condensing unit (600) to service both evaporation coil systems to achieve new efficiencies in the cost, refrigeration capacity, and thermal and mechanic attributes of the system. Moreover, an efficient dual air over air flow assembly is disclosed wherein chilled air is moved within the upper chilling zone in a manner that leverages the native configuration and cabinet surface areas of the evaporation coil

A locker assembly insert (10) for a cabinet (11) (shown in phantom). In this case the cabinet (11) is a two door cabinet having a first door (12) and a second door (13) (these doors are shown open in FIG. 4), The cabinet has a base (14) opposite sides (15) (and 16), a back (17) and a top (18). A central mullion (19) having a rear cover plate divides the cabinet (11) down the middle and the doors (12) and (13) close the cabinet. The locker assembly insert (10) in this case is applied to a two door cabinet and has a central support member (20) (which is put in place by first removing the rear cover plate behind the central mullion (19), the rear cover plate is tucked in behind the central support member (20) before assembly allowing it to be reused if the refrigerator is ever restored to its original condition), a pair of vertical side rails (21) and (22), a pair of bases (23) and (24), a pair of tops (25) and (26). This gives the basic door frame. The insert is completed using vertical divider sets (27, 28 and 29) and ten door locker door assemblies (30) and (31).
