A refrigerator is proposed. Due to a first heater provided in a damper assembly, a damper assembly or the connection portion of the damper assembly with a supply duct is prevented from freezing, and due to a second heater provided in the supply duct, the connection portion of the supply duct with the damper assembly or the inside of the supply duct is prevented from freezing.

An ice making system for creating clear ice and an associated method are provided. The ice making system employs a first sealed refrigerant system connected to a heat exchanger. A second sealed refrigerant system is also connected to the heat exchanger for cooling a first refrigerant of the first sealed refrigerant system. A heat exchanger heater is at least partially contained with the heat exchanger for heating the first refrigerant. A pump in the first refrigerant system is activated after heat exchanger heater has warmed the first refrigerant, enabling a cooling cycle to begin. Once sufficient clear ice has been generated, the pump is deactivated.

Provided is a heating device and a refrigerator. The heating device includes a cylinder body provided with a pick-and-place opening, a door body configured to open and close the pick-and-place opening, an electromagnetic generating module configured to generate an electromagnetic wave signal, and a radiating antenna. The radiating antenna is configured to be electrically connected with the electromagnetic generating module to generate electromagnetic waves of a corresponding frequency according to the electromagnetic wave signal. The heating device further includes a signal processing and measurement and control circuit for measurement and control processing of the electromagnetic wave signal. The signal processing and measurement and control circuit is configured to be electrically connected with the electromagnetic generating module and is disposed at a rear lower part in the cylinder body, which not only can make the cylinder body have a relatively large storage space, but also can avoid the damage to the circuit due to excessively high food when a storage drawer is used for holding food.

A receiving enclosure for receiving goods, the receiving enclosure having one or more doors movable between an open position and a closed position, and a locking device adapted to releasably secure the one or more doors in the closed position.

A ventilation unit for a freezer chamber, with a conduit and at least one heating element, wherein in the conduit, at least in sections, an air-permeable filler material is disposed, as well as a freezer chamber with such a ventilation unit as well as methods for operating such ventilation unit.

Provided is a vacuum adiabatic body. The vacuum adiabatic body includes an alternating current line through which AC current flows as a driving source, a direct current line through which direct current flows as a driving source, and a signal line through which a control signal flows as electric lines configured to electrically connect the first space to the second space. Thus, the number of lines passing through the vacuum adiabatic body may be reduced.

The present disclosure relates to an appliance. In one embodiment, the appliance has an enclosed structure which includes a first portion configured to receive one or more meal cartridges, and store and preserve the meal cartridges at a selected temperature range; a second portion; and transfer mechanism configured to transfer at least one meal cartridge in the first portion to the second portion within the enclosed structure in response to a command input for cooking the at least one meal cartridge. The second portion is configured to accept the at least one meal cartridge, receive a cooking instruction command including a cooking duration and temperature determined for the at least one meal cartridge, and cook the at least one meal cartridge based upon the cooking duration and temperature.

A method for reducing sweating in a temperature-controlled display device includes receiving values of an ambient temperature, a door frame temperature, and relative humidity. The method can also include estimating a value of a dewpoint temperature using the values of the ambient temperature and the relative humidity. The method can also include determining control decisions for a door frame heater of the temperature-controlled display device using the value of the dewpoint temperature and the door frame temperature, and transitioning the door frame heater between an on-state and an off-state using the control decisions to maintain the value of the door frame temperature at or above the value of the dewpoint temperature.

Disclosed is a refrigerator including: an ice maker. The ice maker includes a tray; a water supplier configured to supply water into the tray; a heater configured to heat water supplied into the tray; a cooler configured to cool the tray; a condensate collector configured to collect water vapor from the tray, separate the collected water vapor into condensate and air, and transfer the separated condensate to the water supplier; and a controller configured to control the water supplier and the heater to generate the water vapor by raising a temperature of water supplied into the tray above a boiling point, and controlling the cooler to turn water, of which a dissolved air concentration is reduced due to the generation of the water vapor, in the tray into ice.
