Abstract
A solid-state refrigeration device includes a solid-state cooler, first and second heat exchangers, a heat medium circuit, a reciprocating transport mechanism to transport a heat medium of the heat medium circuit, and an operation switching mechanism. The operation switching mechanism is configured to switch between a heating operation and a defrosting operation. In the heating operation, the heat medium heated by the solid-state cooler is caused to release heat in the first heat exchanger, and the heat medium cooled by the solid-state cooler is caused to absorb heat in the second heat exchanger. In the defrosting operation, the heat medium cooled by the solid-state cooler is caused to absorb heat in the first heat exchanger, and the heat medium heated by the solid-state cooler is caused to release heat in the second heat exchanger.
