Low temperature district heating systems represent an important share of the future heating supply. Such systems utilize waste heat from different systems and the heat from renewable sources. Furthermore, they show a potential to be implemented as a link between various energy sectors. The low temperature level of the district Read more…
Within the ERC project SUPERCOOL and ARRS project J2-1738 we have developed a new, unique numerical model that serves as a tool for parametric analysis and the development of micro-cooling systems for cooling of electronic components based on electrocaloric and elastocaloric materials. An article entitled: Caloric micro-cooling: Numerical modeling and Read more…
The article was published in the Journal of Applied Physics and is available here.Thermal control elements, i.e., thermal diodes, switches, and regulators, can control the heat flow in an analogous way in how electronic devices control electrical currents. In particular, a thermal diode allows a larger heat flux in one Read more…
