A refrigeration appliance with multiple storage compartments has a refrigerant circuit with a first expansion valve, a first heat exchanger, a second expansion valve, and a second heat exchanger connected in series between pressure and suction connections of a compressor. Each heat exchanger is associated with at least one storage compartment in order to control its temperature. A control unit controls the compressor rotational speed and positions of the expansion valves. The control unit has a continuously linear regulator for each storage compartment with a P-component for estimating a required temperature control output using a difference between actual and target temperatures. A model computing unit ascertains a target evaporation temperature for a first storage compartment controlled by the first heat exchanger, and for a second storage compartment controlled by the second heat exchanger. The heat exchangers are operated by selecting the compressor rotational speed and the valve positions of the expansion valves.

According to the present disclosure, a method for controlling a refrigerator includes operating a cooling device at a previously-determined output for cooling a storage space; measuring, by a temperature sensor, a temperature of the storage space in unit times; determining a representative temperature of the storage space based on the temperature measured by the temperature sensor, and determining whether the determined representative temperature of the storage space falls within a convergence temperature range, when an output change time is reached after the output of the cooling device is previously determined; maintaining the output of the cooling device or determining the output of the cooling device according to one of a plurality of methods including a first method and a second method when the representative temperature of the storage space falls within the convergence temperature range, and determining the output of the cooling device according to the second method when the representative temperature of the storage space is out of the convergence temperature range; and operating the cooling device at the determined output.

An improved portable cooler can be configured to provide access to its contents from multiple orientations while reducing the likelihood of water spillage or contamination. The improved portable cooler may optionally include one or more sliding compartments to allow access to the contents of the portable cooler when the cooler is arranged in any of a horizontal or vertical orientation.

A cabinet with anti-condensation mechanism is used to control opening and closing a cabinet door of the cabinet. The cabinet includes a control module, a temperature control module, and a locking module. The control module senses a cabinet-inside temperature inside the cabinet, and senses cabinet-outside temperature and a cabinet-outside humidity outside the cabinet to generate a dew-point threshold value. The temperature control module is used to adjust the cabinet-inside temperature. The locking module is used to lock the cabinet door or unlock the cabinet door. The control module controls the locking module according to the cabinet-inside temperature and the dew-point threshold value, and controls the temperature control module to adjust the cabinet-inside temperature to be greater than or equal to the dew-point threshold value when the control module receives a trigger signal.

A refrigerator comprises a storage compartment configured to store food, a temperature detector configured to detect an internal temperature of the storage compartment, a cooler configured to supply cool air to the storage compartment, a microphone configured to receive a speech, a display configured to display information, at least one processor configured to be electrically connected to the temperature detector, the microphone, and the display; and a memory configured to be electrically connected to the at least one processor. The memory stores at least one instructions configured to, when a first speech including a food name is recognized via the microphone, allow the processor to display a food list, which comprises food information corresponding to the food name and an identification mark identifying the food information, on the display, and configured to, when a second speech referring to the identification mark is recognized via the microphone, allow the processor to display food purchase information corresponding to the identification mark, on the display.

A method for controlling the temperature and humidity level of the air contained in an enclosed refrigerated space includes the step of measuring the temperature of air in the space. The space includes a cooler having a plurality of cold batteries; at least one coolant temperature sensor at the input and at least one coolant temperature sensor at the output of the cooler; at least one fan with an adjustable, reversible direction of ventilation for producing a variable flow of air through the cooler; at least one temperature sensor upstream of the fan; at least one temperature sensor downstream of the cooler; at least one humidity level sensor upstream of the fan; and at least one humidity level sensor downstream of the cooler. The control is affected by reference values given initially for the temperature and humidity level in the enclosed space.

A method of controlling a refrigerator is disclosed. The method includes: operating a cool air supply means with a predetermined output; a controller determining the output of the cool air supply means based on a current temperature of a storage compartment sensed by a temperature sensor while the cool air supply means operates with the predetermined output; and the controller operating the cool air supply means with the determined output. The controller determines that the output of the cool air supply means is decreased or increased when an absolute value of a difference between a previous temperature and a current temperature of the storage compartment is equal to or greater than a first reference value, and wherein the output of the cool air supply means is decreased or increased again when the absolute value of the difference between a current temperature of the storage compartment sensed again after a predetermined time has elapses and the previous temperature of the storage compartment is equal to or greater than the first reference value.

A refrigerated food pan cooling device includes a food pan receiving well and a cooling system, wherein the cooling system includes a refrigeration system with a compressor, a condenser, a metering device and an evaporator. The evaporator includes at least one first refrigerant line downstream of the metering device and upstream of the compressor. The first refrigerant line runs along an external surface of at least one of the well walls. The condenser is configured as a hot wall condenser, that lacks any fan or blower, wherein the hot wall condenser includes at least one second refrigerant line downstream of the compressor and upstream of the metering device.

A refrigerator includes a refrigerator cabinet, a fresh food compartment disposed within the cabinet, a freezer compartment disposed within the cabinet, an ice compartment disposed within the cabinet, and an electronic control system associated with the refrigerator and adapted to monitor and control the fresh food compartment, the freezer compartment and the ice compartment. The control system provides for energy efficient control and operation through various means, including by monitoring state of an ice maker associated with the ice compartment and controlling temperature within compartments of the refrigerator based on the ice maker state. A damper controls air flow between the fresh food and freezer compartments. The control system can direct heat to the damper if the damper becomes frozen.
