High-temperature CO2 Transcritical Heat Pump with Optimized Tube-in-tube Heat Exchanger
In existing research, 90 °C is reported as the highest temperature of hot water supplied by a traditional CO2 heat pump. To supply pressurized hot water over 100 °C with the CO2 transcritical heat pump, a tube-in-tube heat exchanger was redesigned and ...

Ultra-high-temperature electrocaloric heat pump
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
