High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam
Chemie Ingenieur Technik, Volume 98, Issue 7, Page 364-373, July 2026.This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.

Effect of inlet subcooling on flow boiling in microchannels
Applied Thermal Engineering, 2020 Abstract The paper describes experimental work to assess the effect of inlet subcooling on the flow boiling characteristics of HFE-7200 in a multi-microchannel heat sink. The experiments were performed at a mass flux of 200 kg/m2 s and system pressure of 1 bar for inlet subcooling conditions of 5 K, 10 K and 20 K and wall heat flux between 25.9 and ...

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns
Chemie Ingenieur Technik, Volume 98, Issue 7, Page 374-385, July 2026.Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.
