Experimental optimization of an absorption-compression heat pump with wet compression for large temperature glide industrial applications

Hamid, Khalid; Ren, Shuai; Tolstorebrov, Ignat; Hafner, Armin; Sajjad, Uzair; Arpagaus, Cordin; Moen, Ole Marius; Eikevik, Trygve Magne (Peer reviewed; Journal article, 2025)

The present work demonstrates the experimental optimization of a single-stage compression-absorption heat pump system for an application with a large temperature glide on the heat sink side using wet compression. The primary ...
Screening of Future-Proof Working Fluids for Industrial High-Temperature Heat Pumps up to 250 °C (Part I)

Pachai, Alexander C.; Normann, Jeannett; Arpagaus, Cordin; Hafner, Armin (Chapter, 2021)

If industry wants to phase out fossil steam boilers, heat pumps will have to produce steam at a temperature of about 160 °C or higher, as this is a kind of standard in current steam systems. Even 250 °C is used in some ...
