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 monitoring and controlling system for product holding arrangements, food bars and the like includes functional stations holding products at different locations and a station serving unit with a server and in communication by a local network with the functional product stations that have digital displays. The station serving unit communicates with a portable unit with a display and a scanner for scanning product label codes with product information via a wireless local network, and holds information about all products held in the stations and their current locations. Information is updated through scanned product label code information and/or instructions from the portable unit and through information from the functional product holding stations. The portable unit contains at least part of the information in the station serving unit, and has an interactive user interface enabling handling, controlling, and monitoring at least the products via the portable unit.

There is disclosed a refrigerator; a lighting device provided in the storage chamber, a first door rotatably coupled to the case to open and close the storage chamber, an auxiliary storage chamber provided in the first door, a second door, a front panel formed of a transparent material, an evaporation treatment unit evaporated on an overall back surface of the front panel to transmit lights partially, a variable transparency film attached to a back surface of the evaporation treatment unit provided in the front panel to get transparent when the power is supplied, a frame unit with an opening having a corresponding size to an opening provided in the first door, an insulation panel distant from the front panel, a power supply unit for supplying an electric power to the variable transparency film and the lighting device, a proximity sensor provided in the second door to sense a user's approaching.

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.

An augmented refrigerated display unit is provided. The refrigerated display unit includes a door being hingedly attached to the refrigerated display unit, an augmentation drive operatively connected to a hinge of the door for applying an assistive force to the door, and an initiation sensor configured to detect an application of a manual force to the door. The augmentation drive applies an assistive opening force to the door in response to detection by the initiation sensor of an application of the manual force to open the door, a holding force in response to a detection of the door reaching an open position, and an assistive closing force to the door in response to a detection of the manual force being applied to close the door.

A refrigeration system including an evaporator defining an evaporator envelope and positionable to condition an airflow, the evaporator including an airflow inlet, an airflow outlet, and one or more refrigerant coils. The refrigeration system also includes a pressure sensor that is positioned to detect an outlet air pressure at or adjacent the outlet, and positioned to detect one or both of an ambient air pressure and an inlet air pressure and to generate a signal indicative of the corresponding air pressure. A control system in operative communication with the pressure sensor to determine a pressure differential based on the signal indicative of the outlet air pressure and the signal indicative of the ambient air pressure or the inlet air pressure, the control system configured to selectively initiate a demand defrost of the evaporator based on the determined pressure differential.

Condensation management systems and methods including a control unit and a plurality of auxiliary fan devices. The control unit includes fan, heating element and controller maintained by a housing, and a sensor. The auxiliary fan devices each include a fan electrically connected to the controller and that can be selectively installed to a refrigerated display case apart from the housing. The controller operates to prompt operation of the heating element, the fan, and the auxiliary fan devices in response to sensed information.

A controller for a refrigerated display case includes processing circuitry configured to receive operational data from multiple refrigerated display cases and an ambient temperature reading from an ambient temperature sensor. The processing circuitry is configured to determine a limp level for a rack that includes the multiple refrigerated display cases based on the operational data and the ambient temperature reading. The processing circuitry is configured to determine an operational cooling parameter for each of the multiple refrigerated display cases based on the limp level. The operational cooling parameter indicates an amount of cooling or a corresponding cooling operation for each refrigerated display case. The processing circuitry is configured to operate each of the multiple refrigerated display cases using the operational cooling parameter.

A heat exchanger for a temperature controlled case is disclosed herein. A temperature controlled case includes a housing that defines a temperature controlled space. The housing includes a duct that receives circulated air. A heat exchanger is coupled to the housing and disposed within the duct. The heat exchanger includes an intake face at a non-perpendicular angle relative to an air flow direction in the duct immediately upstream of the heat exchanger.
