Fossil fuels are generally consumed to meet the heating, cooling and dehumidification needs of conventional sunlight greenhouses. How to equip a greenhouse with innovative thermal solutions to better recover, store and use excess solar energy to heat/cool the greenhouse remains a scientific and technological lock. The excess heat must be removed and can be stored using seasonal and/or daily thermal energy storage technology. This stored excess heat can then be used later to meet the thermal load (heating and cooling) of the greenhouse. At the same time, 20-30% of the energy consumed is used to dehumidify the greenhouse, usually by ventilation. Developing solutions to better manage hygrometric needs is another important challenge, especially for fully or semi-enclosed greenhouses. Nevertheless, the thermal energy storage and dehumidification systems must be designed and sized according to the thermal and hygrometric load for each particular case.


The enrolled postdoc research will work on the design, sizing and dynamic numerical modelling of thermal energy storage systems (short-term and long-term) and dehumidification systems with application to the new generation of net-zero energy sunlight greenhouses. Based on the background work and expertise of the LTEN research team, the main mission of this postdoc study is firstly to develop a simplified model (type 1st order) for each storage or dehumidification component. Then, detailed dynamic modeling of each component will be performed so as to develop fin models compatible with the Modelica language to be integrated to the global environment of a sunlight greenhouse. Their dynamic behaviors and their integration to the built-environment will be particularly addressed.


- PhD holder majoring thermal science; engineering thermophysics or process engineering;
- Sound background knowledge of heat & mass transfer and engineering thermodynamics;
- Good working experiences on dehumidification systems (desiccant cooling, condensation, refrigeration cycles, etc...); good knowledge on thermal energy storage systems and its integration;
- Mastering dynamic modeling tools (Dymola preferred; Simulink; OpenModelica, etc.); mastering programming tools (Modelica preferred, Matlab; Python; etc.); basic CFD tools preferred (but not mandatory);
- High level of communication skills in both oral and written French;
- Good English writing skill;
- Fully involvement with the postdoc project, strong motivation and autonomy, good team work ability, academic integrity and responsible character.

Work Context

This postdoc project will be realized at LTEN-CNRS UMR6607, a research laboratory of the Nantes University and of the French CNRS. Centre National de la Recherche Scientifique (CNRS) is the French largest research organization carrying out research in all scientific fields of knowledge and conducts interdisciplinary programmes. More description of the French CNRS can be found at http://www.cnrs.fr/en/aboutcnrs/overview.htm

The LTEN is a reference academic laboratory of France on the domain of thermal science and energy engineering. It is also well recognized both at the international level and by the industrial world. More information about the LTEN can be found at http://www.polytech.univ-nantes.fr/ltn/en/

The postdoc work is part of a regional project “SERRES+” (https://www.vegepolys-valley.eu/projet-serres/) aiming at developing a new generation of net-zero energy sunlight greenhouses without fossil energy input. The work will be in close collaboration of the GEPEA laboratory (UMR CNRS 6144) on the integration of individual storage and dehumidification units to the global model of greenhouse environment.
