Title:
SOLID-STATE REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/070197
Kind Code:
A1
Abstract:
This solid-state refrigeration device (1) performs a heating operation and a defrost operation. In the defrost operation, frost attached to a second heat exchanger (17) during the heating operation is removed. Solid-state refrigerant substances (12) include a plurality of substances (12a-12e) having different temperatures at which caloric effects are maximum, and the plurality of substances (12a-12e) are disposed in the descending order of the temperatures along an internal flow passage (13). In the defrost operation, the conveyance direction of a heat medium in the internal flow passage (13) with respect to the phase of force field variation is switched to the direction opposite to that in the heating operation.
