A vacuum adiabatic body includes a heat exchange pipeline including at least two pipelines which pass through a first plate and a second plate to allow a refrigerant to move between inner and outer spaces and a sealing plug which allows the heat exchange pipeline to pass through a first point of the first plate and a second point of the second plate without contacting a third space.

Cooler composed by an outer tank, within which a cooling tank and a useful tank are housed, among which there is an array of thermal energy accumulators, and within the tank useful there are temperature compensation chambers.

A refrigerator includes an inner case, an outer case, and an insulating material. The refrigerator includes a first door, a second door where the second door is to open and close at least another portion of a storage compartment, a rotating bar rotatable with respect to the first door or the second door so that the rotating bar covers a gap between the first door and the second door while the first door and the second door are closed; and a rotation guide coupleable to the inner case to guide the rotating bar while the rotating bar is being rotated according to opening and closing of the first door or the second door. The inner case is formed to cover a front member of the rotation guide so that the front member of the rotation guide is unexposed to a front side of the inner case.

A refrigerator includes an inner case, an outer case, a vacuum space, and a liquid-gas interchanger. The inner case defines an exterior appearance of a storage space. The outer case is spaced apart a predetermined distance from the inner case. The vacuum space is provided between the inner case and the outer case, and maintains a vacuum to insulate the inner case from the outer case. The liquid-gas interchanger is arranged in the vacuum space to generate heat exchange between a refrigerant after it is exhausted from an evaporator and a refrigerant before it is drawn into an evaporator.

A refrigerator includes a cabinet having a freezing compartment below a refrigerating compartment, an ice making compartment at a side of the refrigerating compartment, an evaporator, a shroud that is disposed at a front side of the evaporator, a grille panel coupled to a front surface of the shroud, a first cool air guide channel defined between the grille panel and the shroud and configured to guide cool air to a freezing compartment, a second cool air guide channel defined between the grille panel and the shroud and configured guide cool air to the ice making compartment, a freezing fan module disposed between the grille panel and the shroud and configured to supply cool air to the first cool air guide channel, and an ice making fan module disposed between the grille panel and the shroud and configured to supply cool air to the second cool air guide channel.

An insulated cooler with a submersible internal circulating pump is provided. The insulated cooler includes a base, a plurality of sidewalls extending upwardly therefrom, and an open upper end defining an interior volume. The insulated cooler further includes a lid that is removably secured over the open upper end, wherein the lid includes multiple recessed cup holders with sidewalls that extend downwardly into the interior volume of the insulated cooler. The insulated cooler includes a submersible internal circulating pump operably connected to a system of copper tubing that winds around the sidewall of the recessed cup holders. When activated, the submersible internal circulating pump transports melted ice water through the tubing, which cools the sidewall of the recessed cup holders. In this way, the insulated cooler can cool objects within the interior volume and can cool beverages that are supported within the exterior cup holders.

A pan chiller system eschews traditional methods of strapping refrigeration tubing upon an inner liner and obtaining temperature readings from a suction line. The disclosed embodiments overcome shortfalls in the related art by, inter alia, by artfully using a thermal retention assembly that retains refrigeration tubing in the middle of an inner liner. An inner liner may be filled with glycerin or similar products with the glycerin filling a temperature control bulb to obtain accurate temperature readings and avoiding the use of a suction line for such purposes. The disclosed embodiments may also include an air movement system moving cold air at the bottom of the pan and moving air upon the outer sides of the glycerin well and over the top of the well.

A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support. The support includes a main support having a two-dimensional planar structure and crossing a space, and a first bar and a second bar, which respectively extend from both sides of the main support toward a first plate and a second plate, respectively.

A refrigerator includes a plurality of wall modules and a cooling module. At least one of a rear wall module, a left wall module, or a right wall module includes a supply duct provided to supply cold air produced by the cooling module to a storeroom, and a collecting duct to bring air having exchanged heat from the storeroom back to the cooling module.
