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.
Claims24
A refrigerator comprising:
- at least one main body having a vacuum adiabatic body to define at least one first space configured to store items;
- and
- a door configured to open or close the main body to allow access to the first space from a second space,
- a compressor provided in a machine room and configured to compress a refrigerant;
