Abstract: A thermomagnetic cycle device includes: a magneto-caloric element; a magnetic field modulation device that modulates an external magnetic field applied to the magneto-caloric element; a heat transport device that generates a both-way flow of heat transport medium; a phase controller that adjusts a phase difference between a magnetic field phase of change in the external magnetic field generated by the magnetic field modulation device and a flow phase of the both-way flow generated by the heat transport device; and a control device that controls the phase controller. The control device includes: a phase acquisition part that acquires the flow phase of the both-way flow of the heat transport medium or a reaction phase represented by change in heat emitted or absorbed by the magneto-caloric element; and a control part that controls the phase controller based on the flow phase or the reaction phase.

Abstract: A controller is configured to, based on a characteristic information of thermal output with respect to a temperature difference between a hot end and a cold end of a working chamber, changes at least one of a flow rate of a heating target fluid in a high temperature heat exchanger and a flow rate of a cooling target fluid in a low temperature heat exchanger. At least one of the flow rate of the heating target fluid in the high temperature heat exchanger and the flow rate of the cooling target fluid in the low temperature heat exchanger is adjusted such that the temperature difference between the hot and cold ends changes in a direction that increases thermal output.

Abstract: A thermo-magnetism cycle apparatus has a first magneto-caloric element (MCE) element on a low temperature side and a second MCE element on a high temperature side. A first heat transfer medium flows in the first MCE element and a second heat transfer medium flows in the second MCE element. A third MCE element has a first flow passage that flows the first heat transfer medium and a second flow passage that flows the second heat transfer medium. The third MCE element absorbs heat from the first heat transfer medium utilizing a magneto-caloric process and dissipates the absorbed heat partially to the second heat transfer medium. As such, the third MCE element actively transfers heat between the two heat transfer media via the magneto-caloric process. The third MCE element also passively transfers heat between the two heat transfer media.
