“…However, this was accompanied by significant reduction of the heating power. Zhang et al used numerical simulation to investigate the case of the highest number of layers (16) that had so far been reported for an active magnetic regenerator fabricated from La‐Fe‐Mn‐Si‐H compounds. A set of 137 simulations using different magnetocaloric material specifications was used to optimize the layer–length distribution of the regenerator.…”

The need for energy‐efficient and environmentally friendly refrigeration, heat pumping, air conditioning, and thermal energy harvesting systems is currently more urgent than ever. Magnetocaloric energy conversion is among the best available alternatives for achieving these technological goals and has been the subject of substantial basic and applied research over the last two decades. The subject is strongly interdisciplinary, requiring proper understanding and efficient integration of knowledge in different specialized fields. This review article presents a historical and up‐to‐date account of the energy‐related applications of magnetocaloric materials and information about their processing and magnetic fields, thermodynamics, heat transfer, and other relevant characteristics. The article also discusses the conceptual design of magnetocaloric refrigeration and power generation systems and some guidelines for future research in the field.

“…2b) and in accordance with the dependence of transformation strain on the temperature of the SMA [21], that further means that the coldest part of the regenerator would be strained much more than its hottest part and the eCE in the coldest part of the regenerator would be larger compared to its hottest part. In order to overcome this issue and ensure an equal eCE along the regenerator under the steady-state conditions, a layered active elastocaloric regenerator [64] should be applied (analogous to a layered active magnetic regenerator [65] and [66]). That means that different elastocaloric materials with different transformation temperatures should be stacked along the length of the regenerator (in the fluid flow direction).…”

The elastocaloric cooling, utilizing latent heat associated with martensitic transformation in shape-memory alloys, is being considered in the recent years as one of the most promising alternatives to vapour compression cooling technology. It can be more efficient and completely harmless to the environment and people. In the first part of this work, the basics of the elastocaloric effect (eCE) and the state-of-the-art in the field of elastocaloric materials and devices are presented. In the second part, we are addressing crucial challenges in designing active elastocaloric regenerators, which are currently showing the largest potential for utilization of eCE in practical devices. Another key component of elastocaloric technology is a driver mechanism that needs to provide loading for active elastocaloric regenerators in an efficient way and recover the released energy during their unloading. Different driver mechanisms are reviewed and the work recovery potential is discussed in the third part of this work.

The objective of this work is to assess the potential of Mn-Fe-SiP for magnetic heat pump applications. Mn-Fe-SiP is a first order transition magnetocaloric material made from safe and abundantly available constituents. A significant magnetocaloric effect occurs at the transition temperature of the material. The transition temperature can be tuned by changing the atom ratios to a region near room temperature. Mn-Fe-SiP in magnetic heat pumps is investigated by determining the material's properties, 1D system modeling and experiments in a magnetic heat pump prototype. We characterize six samples of Mn-Fe-SiP , based on their heat capacity and magnetization. The reversible component of the adiabatic temperature change is found from the entropy diagram and compared to cyclic adiabatic temperature change measurements. Five of the six samples are selected to be formed into epoxy fixed crushed particulate beds, which can be installed into a magnetic heat pump prototype.
