Solid-state refrigeration device

A solid-state refrigeration device comprising:

• at least one solid-state cooler including a solid refrigerant substance, an internal flow path with the solid refrigerant substance disposed therein, and an inducer configured to induce a caloric effect in the solid refrigerant substance;
• at least one first heat exchanger;
• at least one second heat exchanger;
• at least one heat medium circuit connected to the first heat exchanger, the second heat exchanger, and the internal flow path;
• a reciprocating transport mechanism configured to transport a heat medium of the heat medium circuit in a reciprocating manner;
• and
• an operation switching mechanism configured to switch between
• a heating operation in which
• 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, and
• a defrosting operation in which
• 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,
• the operation switching mechanism including
• a switching mechanism configured to switch between flow paths of the heat medium in the heating operation and the defrosting operation;
• and
• an electronic controller,
• the electronic controller being configured to control the inducer, the reciprocating transport mechanism, and the switching mechanism so as to perform the heating operation and the defrosting operation in a switching manner.
