A one-dimensional time-dependent model of the active magnetic regenerative refrigeration (AMRR) cycle is developed and is validated by experimental measurements. It is based on the convection exchange between a layer of fluid and a thin plate of magnetocaloric effect material. It takes into effect the magnetocaloric properties of the material. This model is… (More)
In this paper, a permanent magnet based device for active magnetic regenerative refrigeration was described. Magnetic regenerative refrigeration is based on giant magnetocaloric effect. The active block of the refrigeration is a cylinder made of stacked gadolinium sheets and equipped with thermocouples.
Electromagnetic relay modeling is elaborated using a magnetic equivalent circuit (MEC). The lumped parameters of the MEC are fitted with respect to 3-D finite-element simulation by using classical optimization algorithms. An accurate dynamic material law has to be taken into account in the modeling, considering the massive core of the circuit. Two accurate… (More)
