Research focus
The Indoor Climate Technology team addresses the subject of indoor comfort while considering not only thermal but also air quality aspects. One focus is the characterization and quantification of air flows and pollutant concentrations as well as their efficient dilution of removal, for residential and non-residential buildings. In particular for indoor areas in manufacturing sites, concepts are developed and verified for air pollution control at workplaces and thus the detection of pollutants. In addition to the removal of substances such as CO2, the focus has shifted to the investigation of aerosol-related infections and protection through various ventilation measures. Investigations are based on computational fluid dynamics or in-situ or laboratory tests (e.g. in room air flow laboratory).
Projects
-
AltParFilt - Investigation of the filter effectiveness and the indoor particle concentrations with alternating residential ventilation systems
The objective of the project is to gain insight via experimental investigations how settled particles in a filter of alternating residential ventilation systems behave upon airflow reversal. -
EDropSep – Development of an energy-efficient, dielectrophoretic droplet separator
In the EDropSep research project, a novel separation concept is developed which allows for a higher energy efficiency in the separation of droplets with diameters in the lower µm area. -
HeatVentCon – Cross-system control strategies for an energetically optimized operation of residential ventilation and heating systems
The objective of the research project is to develop optimized cross-functional control processes for residential ventilation equipment and heating systems. A key aspect is the continuous information exchange of relevant system parameters between both systems. A real-time communication shall be developed for the exchange of the relevant information used by both systems for a demand-orientated control.
