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 vacuum adiabatic body according to the present invention includes a conductive resistance sheet which connects a first plate member and a second plate member to each other; a sealing frame which covers the conductive resistance sheet; a part fixing frame which is supported by the sealing frame; and a part which is mounted on the part fixing frame. According to the present invention, the power necessary for operation can be stably supplied while heat loss is prevented.

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.

In all freezers and refrigerators all have integral plastic inner frame and the refrigerator door mezzanine both are filled with injection-type Styrofoam to keep cold. The plastic inner frames and Styrofoam are both environmentally unfriendly and difficult to recycle and wasteful a lot of energy.

Provided is a refrigerator for a vehicle. The refrigerator for the vehicle may include a cavity or compartment accommodating a product, a machine room disposed at a side of the cavity, a compressor accommodated in the machine room to compress a refrigerant, a condensation module or assembly accommodated in the machine room to condense the refrigerant, an evaporation module or assembly accommodated in the cavity to evaporate the refrigerant and thereby to cool the cavity, a machine room cover defining an inner space of the machine room, and a controller mounted on an outer surface of the machine room cover.

An outer wrapper that defines a top wall, a bottom wall, a rear wall, and first and second side walls and includes an inner liner. A trim breaker seals the outer wrapper to the inner liner to define an insulation space. A single vacuum port is disposed on each of the top wall, the bottom wall, and the first and second side walls. A plurality of vacuum ports is disposed on the rear wall. An insulative material is disposed between the outer wrapper and the inner liner. A filter media is disposed proximate each vacuum port such that air can be drawn from the insulation space past the filter media and through each vacuum port.

Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a supporting unit configured to maintain a vacuum space part. The supporting unit includes a plurality of bars extending in a vertical direction between the first plate member and the second plate member. When a pitch of the bar is a, an elastic modulus of a material forming the bar is E, and a radius of a long axis is n and a radius of a short axis is m when a cross-section of the bar has an elliptical shape is n, the following equation: is satisfied.
