Laboratory for Refrigeration and District Energy Process Engineering domain

Basic Engineering

Our main activities and research interests concern four different, but interrelated pillars:

  • Thermal management
  • Refrigeration & Heat Pumps
  • Thermal energy storage and harvesting
  • District Energy and Energy Planning


Applied Engineering

We are engaged in applied research and development of heat pumps, household appliances, heat exchangers, and other types of processes, devices and systems, related to thermal engineering. We also do planning and optimization of large scale systems, such are new generations of district cooling and heating systems.

Teaching & Students

The laboratory covers pedagogically the basic area of Heat and Mass transfer, Transport phenomena, Refrigeration, Heat pump, Energy supply, and Heat exchangers. We provide students with topics for seminars and bachelor and master theses, or doctoral studies, which are, due to their interdisciplinarity, also suitable for all fields of studies at the faculty.
