Novel Fluorite‐Structured Materials for Solid‐State Refrigeration

Small, 2022
AbstractRefrigeration based on the electrocaloric effect can offer many advantages over conventional cooling technologies in terms of efficiency, size, weight, and power source. The discovery of ferroelectric and antiferroelectric properties in fluorite‐based materials in 2011 has led to diverse applications related to memory (e.g., ferroelectric ...

Light-Emitting Diodes for Solid-State Refrigeration

Light, Energy and the Environment, 2017
Electroluminescence, the conversion of electrons into externally emitted photons, is an intrinsic cooling process in a light-emitting diode as long as the applied voltage is less than the photon energy. When the diode is sufficiently efficient so that cooling due to electroluminescence surpasses heating due to internal losses, it becomes a solid-state ...

Thermal switching requirements for solid state magnetic refrigeration

Journal of Magnetism and Magnetic Materials, 2021
Abstract Magnetic refrigeration, based on the magnetocaloric effect, is an attractive alternative to the conventional vapor-compression technology. In a solid state magnetic refrigerator the traditional alternated fluid flow is replaced by two solid thermal switches (TSs) that control the heat flux.

Thermoelectric module design strategy for solid-state refrigeration

Energy, 2016
Abstract In this paper, a new characterization factor for thermoelectric module design in thermoelectric refrigeration is presented with guidelines for practical design strategy. It has been general practice to optimize the geometric factor (G-factor), the ratio of the area to the leg length of a thermoelectric leg, and the number of leg pairs ...

Electrocaloric materials for future solid-state refrigeration technologies

Progress in Materials Science, 2012
The electrocaloric (EC) effect is an adiabatic and reversible temperature change that occurs in a polar material upon application of an electric field. The current intensive research in EC materials has been driven by the quest for new energy efficient and environmentally friendly cooling technologies.

Solid state refrigeration: Cooling and refrigeration using crystalline phase changes in metal alloys

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2004
The well-known fact that a phase change is normally accompanied by a relatively large change in internal energy is explored and is used to develop an innovative method of achieving refrigerative effects in solid state metal alloys. Applying a cyclic mechanical stress in certain materials can induce crystalline structural changes, with accompanying ...
