Performance analysis of multistage high‐temperature heat pump cycle
Energy Science & Engineering, 2023 AbstractHigh‐temperature heat pumps (HTHPs) that can supply heat at temperatures at and above 200°C have the potential to increase energy efficiency and decrease carbon dioxide (CO2) emissions in industrial processes. In this study, three reversed Rankine cycles using water vapor (R‐718) as the working medium, with different intercooling strategies ...

High temperature heat pump integration into district heating network [PDF]
Energy Conversion and Management, 2020 Abstract This study illustrates the potential of high temperature heat pumps (HTHPs) integration into district heating network (DHN) through a twofold approach, using DHN as a heat sink and source. It is used as a heat sink of HTHP that uses waste heat from the supermarket’s refrigeration system as a heat source whereas it is used as a heat source to
