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.
