 Thermal and economic performance assessment of different high temperature heat pump layouts for upgrading district heating to process heating of steam production at 160°CMohsen Sadeghi, Tage Petersen, Zhenyu Yang, Benjamin Zühlsdorf and Kim Stenholdt Madsen Energy, 2024, vol. 313, issue C Abstract: Benefiting from the electrification, using energy efficient high temperature heat pump is the key technology to tackle the challenges towards decarbonization of process heat. This work aims to upgrade district heating at 85 °C to process heating of supplying 1 MW steam at 160 °C using high temperature heat pump (HTHP) technology. Two different concepts of open and closed steam systems are considered. The former, which directly delivers steam from the compressor to the end user, proposes two layouts of cascade butane/steam and two-stage steam/steam. While the latter-including a two-stage flashed cyclopentane cycle-provides the opportunity, if the customer can't accept steam directly from the compressor, due to the pollution concerns. In the corresponding layouts, the use of either dry or oil injected gas compressor is examined.
