Faculty of Engineering 
Department of Energy and Process Engineering


A PhD scholarship is available at the Department of Energy and Process Engineering (EPT) within the Refrigeration research group on the topic of "High Temperature Heat Pumps " (HTHP).

The Refrigeration research group has long term expertise and a well-established network within of vapor compression systems, applying natural working fluids for various applications within different industrial sectors. This PhD fellowship will be in close cooperation with Shanghai Jiao Tong University in the double PhD program.

The environmental impacts of human activities pose a threat to mankind through climate change. A sustainable and energy-efficient industry is central in continuing to support the needs of an increasing population. The importance of energy efficiency to protect and improve the global environment has been emphasized in several recent publications, such as the European Strategic Energy Technology Plan (SET-plan), and the International Energy Agency's (IEA) World Energy Outlook and Energy Efficiency Market report. The last-mentioned states that the avoided energy use from a long-term improvement in energy efficiency should be the largest contributor. According to the IEA Energy Technology Perspectives, 19% of the contributions needed to reach the 2°C goal in climate change mitigation, which the Norwegian government has also agreed to, have to come from industrial energy efficiency improvements. The role of an energy-efficient industry is to highlight the main areas in the national energy technology strategy.

The PhD work will investigate new HTHP concepts for different industrial applications, including: propane/butane cascade heat pump cycles, mechanical steam recompression cycles, multistage ammonia-water absorption cycles, and ammonia-water compression resorption cycles, and optimize components, cycle architecture and control strategies, set up experimental campaigns for HTHP concepts. The aim is to have HTHP heating processes up to 250oC.


We seek a highly motivated candidate with a Master's degree (or equivalent) within refrigeration and/or in energy engineering. The candidate should present a strong interest for laboratory work. The candidate should document competence in modelling and simulation of complex systems including heat- and mass transfer. A prior and concrete experience with the aforementioned disciplines are considered as an advantage.

Excellent English skills, spoken and written are required. Applicants from non-English speaking countries outside Europe must document English skills by an approved test. Approved tests are TOEFL, IELTS, and Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE).
