Abstract: Low-temperature heat sources are available in many applications, ranging from waste heat marine diesel engines, industries and refrigeration plants to biomass, geothermal and solar heat sources. There is a great potential for enhancing the utilisation of these heat sources by novel cycle design and use of multi-component working fluids. These advancements will not only improve the performance of existing technologies, but also enable the utilisation of low-temperature heat sources, which are currently not utilised due to technical or economical infeasibility.

This project is part of an interdisciplinary project carried out together with DTU – employing a total of 7 PhD students and 6 PostDocs. The specific project will be focused on the heat transfer surfaces to be used in future advanced thermodynamic cycles for harvesting of low-temperature heat sources.
