HVAC

Postdoctoral Fellow in Power-Environment friendly HVAC Methods for Giga Battery Manufacturing unit job with NORWEGIAN UNIVERSITY OF SCIENCE & TECHNOLOGY – NTNU

About the position

The SES group has a broad activity including battery technology as well as heating, ventilation and air conditioning (HVAC) in buildings. The postdoctoral position is part of the NORGIBATF knowledge-building project led by SES in collaboration with the Norwegian battery manufacturing industry (FREYR, BEYONDER, NORSIRK, Nordic Mining and Norsk Hydro). Several Norwegian industries are planning large scale (GWh) battery cell factories to produce batteries for export. This could enable new industries to emerge in Norway. The NORGIBATF project aims to support these industries by developing competence into energy-efficient battery cell production and enable a world-leading research environment within industrial battery production in Norway.

We have a vacancy for a two-year postdoctoral position. The postdoctoral fellowship position is a temporary position where the main goal is to qualify for work in senior academic positions.

Current battery factories are equipped with a dry room where several important steps of the cell assembly are performed. The relative humidity (RH) in dry rooms should be kept extremely low (< 1% RH) to prevent the humidity to alter the long-term battery performance. Keeping such a low RH is an energy-intensive process that represents a large share of the embodied energy in a battery (up to 40%). Therefore, the research aims at improving the energy efficiency of dry rooms.

Two research activities are targeted:

  • The main research activity is based on a system analysis where the hygrothermal dynamics of the dry room and the HVAC system will be investigated together. This will be done using detailed dynamic simulations (eg Modelica or IDA-ICE), calibrated on field measurements, that will serve as virtual experiments. These simulations will enable to derive energy-efficiency measures to improve the design and operation of dry rooms.
  • The secondary activity will investigate the ventilation air distribution in the dry room using Computational Fluid Dynamics (CFD) calibrated on field measurements. The air distribution should be optimized to keep the RH below the threshold at all locations in the dry room for a minimum airflow rate.

The Head of Department is Professor Terese Løvås. The day-to-day position management is by Associate Professors Laurent Georges and Bjørn Austbø. The NORGIBATF project is managed by Professor Odne Burheim, head of the SES group.

Duties of the position

  • Develop a virtual dynamic model of a dry room calibrated on a real test case
  • Perform field measurements to support the development of the model
  • Analysis of the energy-efficiency of dry rooms to optimize their design and operation
  • Analysis of the ventilation airflow distribution in dry rooms

Required selection criteria

  • You must have completed a Norwegian doctoral degree or corresponding foreign doctoral degree recognized as equivalent to a Norwegian PhD
  • You must have a professionally relevant background in HVAC engineering or dynamic analysis of industry processes (eg from process, cybernetic or control engineering)
  • Proficient user of dynamic simulation tools like Modelica, TRNSYS or IDA ICE
  • Excellent written and oral English, TOEFL (minimum 95) or IELTS (minimum 6.5)
  • The selected candidate is expected to start the position during spring 2022

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, post doctor and research assistant

Preferred selection criteria

Research or professional experience in one or several of the following domains will be appreciated:

  • Documented knowledge/experience of desiccant wheel technology
  • Documented knowledge/experience with CFD
  • Background in data-driven modeling of systems
  • Expertise in data pre- and post-processing tools like Python or MATLAB
  • Knowledge of building physics
  • Experience with field measurements of indoor environment or energy use in buildings or industrial premises
  • Knowledge of the Norwegian language will be considered as an advantage
  • Documented experience in scientific writing, typically peer-reviewed journal papers.

Personal characteristics

  • Confidence in working independently
  • Ability and willingness to work in inter- and transdisciplinary teams
  • creativity
  • critical thinking
  • Excellent communication skills
