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.

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.

EventFlow: Real‐time neuromorphic event‐driven classification of two‐phase boiling flow regimes

Droplet, Volume 5, Issue 3, July 2026.
We present a real‐time flow regime classification framework that integrates neuromorphic event‐driven sensing with deep recurrent neural networks. Unlike traditional frame‐based approaches, our system captures sparse event streams from an event‐based camera, representing only the dynamic brightness changes at the individual pixel level.

Assessment of the performance of ultralow‐GWP refrigerants in a two‐stage heat pump system using simulation and MCMD

Environmental Progress &Sustainable Energy, Volume 45, Issue 4, July/August 2026.
Abstract The Kigali Amendment's mandate to phase down high‐GWP refrigerants highlights the urgent need for sustainable alternatives in cold climate heat pumps, which are critical for delivering efficient heating in severely cold regions. This study evaluates ultralow‐GWP refrigerants—R‐290, R‐152a, R‐161, R‐1234yf, and R‐1234ze(E)—for application in a ...
