摘要： A vacuum adiabatic body may include: a first plate member; a second plate member; a sealing part sealing the first plate member and the second plate member to provide a third space; a supporting unit maintaining the third space; a heat resistance unit at least including a conductive resistance sheet capable of resisting heat conduction flowing along a wall for the third space to decrease a heat transfer amount between the first plate member and the second plate member; and an exhaust port through which a gas in the third space is exhausted. A side frame may be fastened to the conductive resistance sheet and the second plate member, and the side frame is fastened to an edge portion of the second plate member. Accordingly, the formation of dews may be prevented and an adiabatic effect may be improved.

摘要： A cryogenic cooler includes a cold region, a heat-transfer fluid circuit, the cold region being positioned in the circuit, and an application heat exchanger configured to exchange calories with a device to be cooled. The cooler includes at least one passive non-return valve fluidly connected to the cold region, the heat exchanger having at least one first fluid inlet positioned downstream of the non-return valve in the flow direction of the heat-transfer fluid, the heat-transfer fluid circulating from the end of the cold region.

摘要： A vacuum adiabatic body includes a first plate, a second plate, a seal to create a vacuum between the first and second plates, and a support to maintain a distance between the first and second plates. At least one of the first or second plates may have a predetermined thickness. The support includes a plurality of bars or posts interposed between the first and second plates and arranged in a grid having a predetermined pitch. A bending angle may be formed between points corresponding to where the plurality of bars are provided and points corresponding to positions that are furthest away from the bars.

The vacuum adiabatic body further includes a peripheral adiabatic part provided to an outer wall of an edge portion of the third space to improve the adiabatic performance of the edge portion of the third space, and the peripheral adiabatic part is provided as a separate adiabatic member. Accordingly, an adiabatic effect may be improved and volume of an outer door in a door-in-door refrigerator may be increased.

摘要： A control method for a refrigerator includes sensing a temperature of a storage room; operating a cool air supply at a cooling power when the sensed temperature of the storage room is equal to or above a first reference temperature; operating the cool air supply at a delay power, which is less than the cooling power, when the sensed temperature of the storage room is equal to or below a second reference temperature, which is less than the first reference temperature while the cool air supply is operating at the cooling power; and adjusting the cooling power or the delay power of the cool air supply according to the temperature of the storage room while the cool air supply is operating at the delay power, and operating the cool air supply at the determined adjusted cooling power or delay power.

摘要： A method and system for converting a conventional cooler to a refrigerator. A heat transfer module is disposed within the cooler for cooling the contents therein, while an external cooling module includes refrigerant in a closed loop configuration that stays outside of the cooler. The heat transfer module includes a closed loop chilling fluid that extends outside the cooler through a drain port to perform a heat exchange with the refrigerant loop.

摘要： A camera assembly includes a housing inside of which components are maintained at a cryogenic temperature. The components maintained at cryogenic temperature include a detector that is mounted on an integrated circuit, which in turn is mounted on a platform, such as a ceramic platform, which includes electrical connections for the integrated circuit. The camera assembly also includes one or more subplatforms, maintained above the cryogenic temperature, such as ambient temperature, that receive electrical inputs from outside the housing, and make electrical connections to the platform. The connections may be made from the one or more subplatforms, through openings in the platform and/or outside one or more outer edges of the platform. The assembly may include covers of exposed parts of the one or more subplatforms, to facilitate thermal isolation between the interior of the assembly (at cryogenic temperature) and the one or more subplatforms (above cryogenic temperature).
