The controller is configured to store a plurality of setpoint instruction sets associated with a plurality of possible operating modes, select a current operating mode from the plurality of possible operating modes, assign a value for the superheat setpoint by executing the setpoint instruction set associated with the current operating mode, control the refrigeration system in accordance with the superheat setpoint.

A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate, and a heat resistance unit comprising at least one radiation resistance sheet that blocks radiation heat transfer in the vacuum space so as to reduce heat transfer between the first plate and the second plate. The support includes two support plates, and the at least one radiation resistance sheet is supported by at least one support protrusion provided on a bar, which couples the two support plates to each other, to maintain an interval between the first plate and the second plate.

Provided is a vacuum adiabatic body. To reduce a heat transfer amount between two plates, the vacuum adiabatic body includes: a conductive resistance sheet connecting plate members to each other, an exhaust port through which a gas of a third space is exhausted, and a sealing frame covering a conductive resistance sheet. A virtual line connecting both end portions of the conductive resistance sheet to each other is installed to be obliquely inclined when at least one extension direction of a first plate member or a second plate member is viewed in a horizontal direction.

A cooler box with a temperature control function, the cooler box comprises a box body and a cryogenic medium container installed outside the cooler box for storing liquid carbon dioxide or other liquefied gas. The box body is equipped with a controller, a monitoring device, a controllable valve, and a chamber to reduce the speed of gas released and thus prevent sudden freezing and overcooling of temperature-sensitive cargo such as fresh food. The controllable valve is connected to the cryogenic medium container through a tube. The monitoring device measures the temperature inside the cooler box, and the controller controls the valve opening state and the duration time of maintaining the open state of the controllable valve according to the temperature measured by the monitoring device and the size of the cooler box. A temperature control method for the cooler box is also provided.

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.

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 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.
