Abstract
A vacuum adiabatic body between a first space and a second space 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.
Claims24
A vacuum adiabatic body comprising:
- a first plate configured to define at least a portion of a wall for a first space, the first plate having a first opening;
- a second plate configured to define at least a portion of a wall for a second space, the second plate having a second opening;
- a third space provided between the first plate and the second plate and configured to be a vacuum space;
- a support configured to maintain a distance between the first plate and the second plate;
- a heat resistance sheet configured to reduce a heat transfer between the first plate and the second plate;
