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 device comprises an element bed providing a plurality of unit channels each containing an NICE element. The heat transport device has a channel switching mechanism and a biasing mechanism. The channel switching mechanism forms an inlet valve for allowing the heat transport medium to flow into the unit channel and an outlet valve for allowing the heat transport medium to flow out of the unit channel. The biasing mechanism applies different biasing forces to the inlet valve and the outlet valve. The magnitude relationship of the biasing force is the same as the magnitude relationship between the pressure of the heat transport medium acting on the inlet valve and the pressure of the heat transport medium acting on the outlet valve.

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.
