Solid-state refrigeration: A comparison of the energy performances of caloric materials operating in an active caloric regenerator

Energy, 2018
The energy performances of an Active Caloric Refrigerator are reported in this paper. An ACR is tested under a vast number of solid-state refrigerants exhibiting one of the four main caloric effects considered for refrigeration (magnetocaloric ...

Plastic crystals could be solid-state refrigerants

C&EN Global Enterprise, 2019
Regulators and manufacturers started phasing out chlorofluorocarbon gas refrigerants like Freon in the late 1970s after scientists discovered that they could deplete the ozone layer. But their replacements, hydrochlorofluorocarbons and hydrofluorocarbons, are greenhouse gases.

Device Model for a Solid-State Barocaloric Refrigerator

Energy Technology
Solid‐state refrigeration represents a promising alternative to vapor compression cooling systems. Solid‐state devices based on magnetocaloric, electrocaloric, and elastocaloric effects have demonstrated the ability to achieve high‐efficiency, reliable, and environment‐friendly refrigeration. Cooling devices based on the barocaloric (BC) effect—entropy

The Los Alamos Solid-State Optical Refrigerator

1997
Optical refrigeration may provide the physical basis for solid-state cryocooling. Devices based on this physics would be vibrationless, compact, and free of electromagnetic interference. Having no moving parts and being pumped by a diode lasers, optical refrigerators would be rugged with operating lifetimes of years.

Laser-induced lensing effects in solid-state optical refrigerators

Applied Physics Letters, 2013
Laser-induced thermal and population lensing effects in solid-state optical refrigerator materials are quantitatively evaluated. Time-resolved lensing transients in Yb3+ doped ZBLAN and aluminosilicate glasses are measured, and the model decouples thermal and population lensing effects. The analysis yields the net power density, the cooling efficiency,
