Abstract: Provided is a vacuum adiabatic body. The vacuum adiabatic body includes an alternating current line through which AC current flows as a driving source, a direct current line through which direct current flows as a driving source, and a signal line through which a control signal flows as electric lines configured to electrically connect the first space to the second space. Thus, the number of lines passing through the vacuum adiabatic body may be reduced.

Abstract: A refrigerator including an inner case, an outer case, and a vacuum space provided between the inner case and the outer case to insulate the inner case from the outer case. The inner case defines an exterior appearance of a storage space, with a communication hole formed therein. The outer case is spaced apart a predetermined distance from the inner case, and a communication is formed at a position corresponding to the communication hole of the inner case. A connection pipe passes through the vacuum space to connect the communication hole of the inner case and the communication hole of the outer case with each other.

Abstract: A vacuum adiabatic body includes a heat exchange pipeline and a sealing plug. The heat exchange pipeline includes 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. The sealing plug 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.

Abstract: A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate, and a heat resistance unit comprising at least one radiation resistance sheet that blocks radiation heat transfer in the vacuum space so as to reduce heat transfer between the first plate and the second plate. The support includes two support plates, and the at least one radiation resistance sheet is supported by at least one support protrusion provided on a bar, which couples the two support plates to each other, to maintain an interval between the first plate and the second plate.
