Abstract
This technical report provides an overview of the performance of different heating and cooling caloric systems: magnetocaloric, elastocaloric, electrocaloric, and barocaloric heat pumps. It compares the performance of these innovative caloric heat pump systems with that of traditional vapour-compression heat pumps. This review focuses on heating and cooling applications at near room temperature for indoor environment conditioning or sanitary hot water production (-30 °C to 100 °C). High-temperature and cryogenic applications (e.g., hydrogen liquification) are thus not included in this report. This overview is based on experimental and numerical data collected from 209 scientific publications and public technical reports.
