About the project

A two-stage heat pump for industrial waste heat

“Implementation of an innovative two-stage heat pump for the electrification of high-temperature thermal processes — DUOHEAT”, grant No. FENG.02.03-IP.05-0014/25, funded by the Foundation for Polish Science under the TEAM NET FENG programme.

Consortium

Three institutions, one technology

DUOHEAT is carried out by a consortium of three Polish research institutions, each responsible for a distinct part of the system.

Project lead & coordination

Gdańsk University of Technology

Leads the consortium and coordinates the project. Project lead: Prof. Dariusz Mikielewicz, Director of the Institute of Energy at Gdańsk University of Technology.

Compressor development

Institute of Fluid-Flow Machinery, Polish Academy of Sciences

Develops the high-speed, oil-free, multi-stage centrifugal compressor that sits at the core of the heat pump — the component the project's temperature-lift target depends on most directly. The work runs from thermodynamic and flow analysis through rotor-dynamics and strength calculations to a prototype, full-range testing, and a machine-learning-based diagnostic system. Team: Dr Łukasz Witanowski and Dr Piotr Klonowicz (Department of Turbines, project lead), Dr Artur Andrearczyk, Dr Paweł Bagiński and Dr Łukasz Breńkacz (Department of Turbine Dynamics and Diagnostics), and Dr Jarosław Karwacki (Department of Heat Exchange).

Heat exchangers

AGH University of Krakow

Designs and selects the heat exchangers for the two-stage system, and works on the construction and optimisation of the upper heat source, using CFD simulations and metamodel-based optimisation to develop high-efficiency exchanger designs. Team: Dr Krzysztof Sornek, Karolina Papis-Frączek and Maksymilian Homa (Department of Sustainable Energy Development, Faculty of Energy and Fuels), with the work led by Dr Marcin Jankowski.

Funding

TEAM NET FENG, Foundation for Polish Science

DUOHEAT is one of eight projects selected in the second TEAM NET FENG call, a programme addressed at consortia of two or three Polish research teams working on solutions relevant to industry, health and the environment.
