Magnetocalorics or electrocalorics: will either replace the gas compressor in high-efficiency refrigeration appliances?

Number: 1502

Author(s) : WILSON N.

Summary

With the development of mass-produced and tunable magnetocaloric (MC) refrigerant materials, high-span, low-field, multi-material regenerators that approach the Rowe ideal [5] can now be fabricated. These materials are relatively low cost and when coupled with inexpensive ferrite magnets MC cooling promises to be a cost-effective technology. Concurrently there are exciting developments in electrocaloric (EC) refrigerant materials, with larger adiabatic temperature changes, broad-transition relaxor ferroelectrics, and industrially producible multi-layer capacitor (MLC) structures. Devices based on both technologies are emerging that may enable more energy efficient appliances, but it is unclear which (if either) may replace the gas compressor.
