Heat pump / alternative drive magnetocaloric refrigerator adjustable offset by restoring forces.

摘要

Heat pump / alternative magnetocaloric refrigerator drive offset by restitution adjustable force, for producing heat / cold through the magnetocaloric principle, which is based on the effect produced by a magnetic field on certain materials that have ownership of experiment a variation of the magnetic entropy and the temperature associated, to vary the magnetic field. It is characterized by the compensation of the work necessary for the displacement of the movable active regenerator by passive magnetic fields, allowing reduction work contributed to the heat engine to move the active regenerator and consequent increase in performance and attenuation decrease performance with increasing magnetic field strength for a given temperature range.
