Ultra-high-temperature electrocaloric heat pump

open access: yesEnergy Conversion and Management
Nearly a quarter of waste heat is generated at temperatures exceeding 300°C, yet conventional heat pump technologies remain inefficient in recovering and utilizing heat from such high temperature sources. In this study, we introduce a novel electrocaloric heat pump designed to operate with heat sources and sinks at ultra-high temperatures. The proposed

Improved district heating network operation by the integration of high-temperature heat pumps [PDF]

open access: yesInternational Journal of Sustainable Energy, 2017
Biomass combined heat and power (CHP) plants connected to district heating networks are a very good opportunity to increase the share of renewable sources into energy systems. Frequently, important consumers are connected to ensure a stable base heat demand throughout the year but they often have higher requirements in terms of temperature (i.e. steam),
