Abstract
A solid-state refrigeration apparatus includes a solid cooling structure, first and second heat exchangers, a heating medium circuit, a reciprocating conveying mechanism, and a thermal storage section. The solid cooling portion includes a solid refrigerant substance, an internal channel where the solid refrigerant substance is disposed, and an induction section configured to cause the solid refrigerant substance to produce a caloric effect. The heating medium circuit is connected to the first and second heat exchangers, and the internal channel. The heating medium heated by the solid cooling portion dissipates heat in the first heat exchanger and the heating medium cooled by the solid cooling portion absorbs heat in the second heat exchanger a heat application operation. Frost on the second heat exchanger is melted using the heat stored in the thermal storage section in a defrosting operation. The thermal storage section stores heat in the heat application operation.
