Abstract: 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.

Abstract: Provided is a vacuum adiabatic body. To reduce a heat transfer amount between two plates, the vacuum adiabatic body includes: a conductive resistance sheet connecting plate members to each other, an exhaust port through which a gas of a third space is exhausted, and a sealing frame covering a conductive resistance sheet. A virtual line connecting both end portions of the conductive resistance sheet to each other is installed to be obliquely inclined when at least one extension direction of a first plate member or a second plate member is viewed in a horizontal direction.
