The merchandise display system includes an outer housing, a transparent front door, a refrigeration unit, and a door that includes an extended canopy. The merchandise display system also includes a front grille for a refrigeration system having, a surface adjacent a curved surface.

A modular refrigeration system includes a refrigeration loop having a compressor, a condenser, an expansion assembly, and a chiller interconnected by a first piping loop cycling hydrocarbon refrigerant. A high side cooling loop includes a first heat exchanger and a first pump interconnected with the condenser by a second piping loop cycling a cooling fluid, the cooling fluid exchanges heat with the hydrocarbon refrigerant at the condenser. A low side cooling loop includes a second heat exchanger and a second pump interconnected with the chiller by a third piping loop cycling a chilled fluid, the chilled fluid exchanges heat with the hydrocarbon refrigerant at the chiller. A space supports the second heat exchanger and is configured to be maintained within a predetermined temperature range, wherein the total charge of hydrocarbon refrigerant associated with the space does not exceed 150 grams.

A refrigerated merchandiser including a case that defines a product display area and an access opening. The case has an air inlet and an air outlet, and a passageway fluidly connects the air inlet with the air outlet to direct a refrigerated airflow across the customer access opening in the form of an air curtain. The merchandiser also includes shelves that are coupled to the case. Each shelf includes an inlet, an outlet, a fan unit disposed in the shelf, and a heat exchanger. The fan unit is in communication with the passageway to draw air through the inlet to direct a portion of the airflow through the shelf toward the outlet. The heat exchanger is disposed in the shelf to cool the airflow in the shelf to provide independent zone cooling to a predetermined region of the product display area.

A temperature controlled case includes a number of shelves, an air-curtain, and a number of air-straighteners. The number of shelves individually support a displayed product. The number of shelves are mounted to the temperature controlled case. The air-curtain originates at an air-curtain discharge and terminates an air-curtain return. The number of air-straighteners is equal to the number of shelves. The number of air straighteners individually include a flow guide and are individually coupled to one of the number of shelves. The flow guides are located at locations within the air-curtain. The flow guides are configured to control the air-curtain. The flow guides individually include a luminaire comprising a number of LEDs coupled to a number of PCBs. The luminaires are configured to illuminate a number of illumination targets. The number of illumination targets correspond to at least one of the displayed products.

An automatic sliding door system includes a door frame having a first end and an opposite second end, configured and adapted for placement at a housing of a cooler; an at least three-parting door connected to the door frame, the at least three-part door including a first door part, a second door part and a third door part, each door part slidably connected to the door frame and in some cases each door part having a rectangular shape; and at least one drive element configured and adapted for moving the first, second and/or third door part. The present disclosure also relates to a cooler with such an automatic sliding door system.

A pusher tray assembly configured to hold products includes a pusher tray including a floor, a bottom surface, a front wall, at least one sidewall, and at least one back wall, where the floor is configured to hold the products thereon; a pusher paddle having a front face and a back face; an engagement mechanism arranged on a lower side of the pusher paddle and configured to secure the pusher paddle to the floor; a channel arranged in the floor and configured to receive the engagement mechanism; a spring configured to urge the pusher paddle and the products towards the front wall; and an inventory control bar configured to at least partially cover the products, where the pusher tray that includes a transparent material.

An inflatable cabinet is provided and includes a first inflatable cabinet stand and a base. The first inflatable cabinet stand is for storing products. The first inflatable cabinet stand includes members and first connectors. The members include side walls, a back wall, and a top member. The base is connected to the first inflatable cabinet stand and includes an air pump, second connectors and air lines. An air pump is configured to pump air into at least one of the members of the first inflatable cabinet stand. The second connectors are configured to connect to the first connectors. The air lines are connected between the air pump and the second connectors.

A showcase includes a casing having a front opening through which a product is picked up, a product storage located in the casing, a cold air outlet in a front upper portion of the product storage, and a cold air inlet in a front lower portion of the product storage. Cold air is forced to flow out of the cold air outlet in a downward direction and sucked into the cold air inlet. The showcase further includes an inlet port in the front lower portion of the casing at a position below the cold air inlet, a duct, a discharge port in a side wall of the casing, and an airflow generator that forces air in the duct to flow from the inlet port toward the discharge port. The air is sucked through the inlet port and the air in the duct is discharged through the discharge port.

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.
