“…Earlier works on room‐temperature magnetic refrigeration mostly utilized superconducting magnets, such as in the first prototype device developed by Brown . A review of a few subsequent prototype devices can be found in the following two references . All these devices generally operated with a rather low frequency and produced a very strong magnetic field, which contributed to the generation of a wide temperature span between the heat source and heat sink.…”

“…An overview of such magnetocaloric materials serving as passive and active magnetic regenerators in cryogenics can be found in the book of Tishin and Spichkin . One of the latest reviews on the different magnetocaloric materials for hydrogen and nitrogen liquefaction was conducted by of Zhang et al Because low‐temperature magnetic refrigerators use a superconducting magnet, the following review article of Gimaev et al on high‐temperature superconductors in magnetic refrigeration can provide good supporting literature. After the second half of the 1960s, when dilution refrigeration reached milli‐kelvin temperatures, the application of magnetocaloric refrigeration in low‐temperature physics was mostly applied in laboratories and on space missions .…”

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.

Vaccines need to be continuously stored between 2°C to 8°C, from their production to administration to beneficiaries. Every year, more than 25% of vaccines are wasted. One of the main reasons for this wastage is the lack of cold chain continuity in low-income settings, where electricity is scarce. Recently, several advances have been made in cooling technologies to store and transport vaccines. The current paper presents a review of refrigeration technologies based on scientific publications, industry white papers and other grey literature. For each refrigeration method, we describe its working principle, the best performing devices available as well as the remaining research challenges in order to obtain a very high degree of performance enhancement. Finally, we comment on their applicability for vaccine transport and storage.

“…The magnitude of the MCE depends on material properties, magnetic field variation and temperature, and it is maximum at the Curie temperature of the material [4,5]. Applications of the MCE at near room-temperature are not restricted to cooling applications [6,7]; it can also be applied to the development of thermomagnetic motors [8,9].…”

Magnetic cooling is an alternative to vapor compression that does not rely on the use of hazardous substances. The refrigerant is a solid material which reacts to oscillations in magnetic field by changing its temperature (the magnetocaloric effect). In active magnetic regenerators, the magnetocaloric material arranged as a porous medium is subjected to an oscillating fluid flow to allow heat transfer from a cold source to a hot sink in a thermodynamic cooling cycle. Although the literature is abundant with studies on the influence of the fluid flow waveform on magnetic refrigeration devices, the influence of the magnetic field waveform has been much less investigated. In this work, we make use of an active magnetic regenerator numerical model with different mathematically defined waveforms to determine which operating parameters yield the highest values of cooling capacity and coefficient of performance for a specific set of operating conditions. The results show that the best performance is achieved when the magnetic field is kept constant for the same time duration of the fluid flow through the magnetized material, and the transition times between the high and low levels of the magnetic field should be as short as possible.
