Exergy analyses of low-temperature district heating systems with different sanitary hot-water boosters

The paper Exergy analyses of low-temperature district heating systems with different sanitary hot-water boosters was published in Entropy Journal. Abstract: This paper presents an exergy-efficiency analysis of low-temperature district heating systems (DHSs) with different sanitary hot-water (SHW) boosters. The main objective of this study was to compare the exergy efficiencies Read more…

New frontiers in magnetic refrigeration with high oscillation energy-efficient electromagnets

The article was published in Applied Energy Journal (link) Abstract This article reports on the novel resistive electromagnetic field source with the magnetic energy recovery, which enables the use of the static magnetocaloric regenerator. Most of the existing prototype magnetocaloric devices that operate near room temperature, use magnetic field sources Read more…

Thermag VII, Darmstadt

In September 2108 we attended the International Conference on Caloric Cooling in Darmstadt. Our contributions were in the field of magnetocalorics and elastocalorics: Rare-earth-free magnetic field source (invited talk), Magnetocaloric wine cooler with rare-earth-free magnet assembly, Challenges in designing elastocaloric regenerators.
