Reinforcement learning is performed on control conditions of the perishable product environment by using information regarding freshness of perishable products by a freshness sensor to automatically control the perishable product environment. There are provided: a freshness determination section 520 acquiring information regarding freshness of a perishable product contained in a storage container; and an analysis section 530 learning, by reinforcement learning, an inside environment of the storage container for the freshness of the perishable product acquired by the freshness determination section 520 to decide a reward used in the learning. The analysis section 530 decides the reward based on the decrease in the freshness over a certain period of time under the inside environment for the freshness determined based on the freshness acquired by the freshness determination section 520. Then, the analysis section 530 learns the inside environment for the freshness based on the decided reward.

A method, which is for controlling a temperature of a refrigerating compartment, includes cooling the refrigerating compartment, cooling the freezing compartment, determining a temperature of the refrigerating compartment, and based on the temperature of the refrigerating compartment, controlling the refrigerating compartment to a constant temperature range by controlling opening and closing of first and second passages of a three-way valve of the refrigerator to alternate cooling the refrigerating compartment and cooling the freezing compartment.

Aspects of the present disclosure describe distributed fiber optic sensing (DFOS) systems, methods, and structures that advantageously enable smart refrigeration systems including retail.

Systems, apparatuses and methods are provided herein for controlling the temperature of a product during delivery. A system for inventory management comprises: an internal compartment; and a delivery control circuit coupled to the internal compartment; a configuration control circuit coupled to the delivery container, the configuration control circuit configured to: identify a product for delivery in the internal compartment; determine an optimum delivery temperature for the identified product; and initially configure the internal compartment to provide the optimum delivery temperature for the identified product, wherein the delivery control circuit is configured to maintain the optimum delivery temperature in the internal compartment during delivery of the identified product.

A multitemperature storage system includes a storage structure including a plurality of upright members , a plurality of horizontal members supported by the upright members and forming a grid pattern defining a plurality of grid cells and allowing containers to be arranged in stacks beneath the grid cells defined by the grid pattern, and a track structure on top of the horizontal members , the track structure being configured to allow a load-handling device to move across the storage structure to retrieve a container from a stack ; and including temperature-control to maintain a first-temperature region within the storage structure at a first temperature and a second-temperature region within the storage structure at a second temperature.

The invention relates to a method for real-time performance check of transport refrigeration units comprising the steps of: comparing via controller temperature sensors by pairs and determining from these comparisons by pairs if one or more temperature sensors are defective or in some extent deviates from expected temperature readings; at the same time measuring/monitoring the mass flow of cooling agent through a compressor and through an evaporator expansion valve V.sub.exp which the controller by comparison determines if mass flow through the compressor do not deviate more than 25% from the mass flow through that evaporator expansion valve V.sub.exp; if said deviation of mass flow through the compressor is more than 25% different from said mass flow through the expansion device V.sub.exp, an error signal is provided

A monitoring, control and feedback system for a refrigeration unit is provided that includes a wireless transceiver operably connected to the control circuitry of a refrigeration unit. The transceiver is operably connected to the central processing unit (CPU) of the refrigeration unit and receives signals from the CPU regarding the operation of the refrigeration unit. The transceiver wireless communicates these signals to a program or application stored and operating on a suitable u ser device that displays the signals illustrating the current operational parameters of the refrigeration unit on the user device while also enabling the user to control the operation of refrigeration unit remotely.

A refrigeration appliance includes a refrigerant circuit having a heat exchanger. The refrigeration appliance also includes a heat circuit. The heat exchanger is thermally coupled to the heat circuit by a coupling element. The coupling element is mechanically connected to the heat circuit by a detachable connection. The detachable connection may be a force-locking connection, in particular a screw connection, a plug-in connection or a form-locking connection, in particular a snap-on connection.

A cold insulation container includes: a cold insulation storage including a coolant vessel; a circulating air fan that causes cold air from the coolant vessel to circulate in the cold insulation storage; a thermoelectric generating module attached to an outer surface of the coolant vessel; and a temperature controller that adjusts a temperature in the cold insulation storage. A temperature difference between the coolant vessel and circulating cold air in the cold insulation storage causes the temperature controller and the circulating air fan to be driven by thermoelectric power generated by the thermoelectric generating module.

A product merchandising system includes a housing having a top surface, two side surfaces spaced apart from one another defining a width-direction of the housing, and a front surface and rear surface spaced apart from one another defining a depth-direction of the housing. The system includes a product support system configured to support rows of products along a width of the housing, each row disposed at a position along the depth of the housing, the first row being towards the front surface of the housing. A cooling system includes a cooling system including a cooling heat exchanger generating an airflow, a deflector configured to direct the airflow through the cooling heat exchanger and towards a bottom of the housing, and a nozzle below the deflector and configured to direct the airflow towards a bottom of the housing through an outlet aperture and between a first two rows of products.
