A method for controlling a refrigerator, includes turning off a cold air transmission unit as a temperature of a storage compartment becomes equal to or less than a second reference temperature while a cold air generator is operated, turning on the cold air transmission unit, upon determining that the temperature of the storage compartment is equal to or greater than a first reference temperature which is greater than the second reference temperature, and calculating, by a controller, an operating ratio of the cold air transmission unit based on ON and OFF time of the cold air transmission unit, determining an output of the cold air transmission unit based on the operating ratio of the cold air transmission unit, and operating the cold air transmission unit with the determined output, upon determining that the temperature of the storage compartment is equal to or less than the second reference temperature.

A frame for a refrigerated enclosure includes a frame segment having, in cross-section, a main frame member including a base, a middle wall, and a forward flange. The forward flange of the main frame member absorbs heat from the ambient air to increase a temperature of one or more locations of the frame segment or a door of the refrigerated enclosure.

A portable cooler container with active temperature control includes a double-walled insulated container body with a chamber to receive and hold temperature sensitive products. A control system is at least partially disposed between an outer wall and an inner wall of the container body. An electronic display screen on one of the lid and the container body configured to display shipping address information for the portable cooler container.

A frame for a refrigerated enclosure includes a frame segment having, in cross-section, a main frame member including a base, a middle wall, and a forward flange. The forward flange of the main frame member absorbs heat from the ambient air to increase a temperature of one or more locations of the frame segment or a door of the refrigerated enclosure.

A refrigerator is provided. The refrigerator includes a main body, at least one door provided on a front surface of the main body, a plurality of storage rooms provided on the main body or the at least one door and configured to store articles, a cooling device configured to cool the plurality of storage rooms, a user interface configured to receive a user input from a user or output information to the user, a communication module configured to communicate with a server and a user device, memory storing one or more computer programs, and one or more processors communicatively coupled to the user interface, the communication module, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the refrigerator to control a temperature of the storage room where a purchased article is stored based on product information of the purchased article received from the server and an estimated consumption date of the purchased article input from the user interface or the user device.

Variable temperature analytical assemblies are provided and/or methods for changing temperatures of a mass are provided. Low thermal conductance components and/or assemblies are also provided. Methods for thermally isolating a mass from a support structure are also provided.

Systems and methods are provided for bimodal refrigeration, which uses a combination of mechanical refrigeration and phase change material (PCM) cells to provide cooling for one or more units of storage, such as freezers, coolers, storage or display cases, open cases (without doors), closed cases (with doors), rack systems (with compressors located remotely), self-contained refrigeration systems (with embedded compressors), in an optimal and efficient manner. In some embodiments, the systems and methods employ intelligent controls which may monitor and receive input for system conditions, time of day, and other conditions, and turn on/off the mechanical refrigeration as appropriate to provide for efficient and cost-effective use of energy.
