On the efficiency of caloric materials in direct comparison with exergetic grades of compressors
Journal of Physics: Energy, 2023 Abstract Efficiency improvements in heat pump can drastically reduce global energy demand. Caloric heat pumps are currently being investigated as a potentially more efficient alternative to vapor compression systems. Caloric heat pumps are driven by solid-state materials that exhibit a significant change in temperature when a field is ...
