LuftKonVerTeR: Calculation and evaluation basis for the dynamic operation of ventilation systems

The overall objective of the project is the creation of calculation and evaluation bases for the dynamic operation of ventilation systems, consisting of air handling units (air conditioning system) and the duct network (air distribution system) for increasing energy efficiency in part-load operation.

Usually, the ventilation systems are designed and optimized for the full load operating point. As most ventilation systems operate for most of the time at partial load, this procedure leads to unfavorable operating behavior in terms of energy use, since firstly the pressure loss of the duct network is unknown and secondly the fan and the components of the ventilation system do not run at the optimum operating point. Therefore, both the air conditioning system and the air distribution system are to be examined for optimal operation under partial load boundary conditions.

The findings are combined in a demonstration system, whereby a comparison between standard ventilation systems and part-load-optimized ventilation systems is established using cloud-based monitoring and control concepts and additionally, new possibilities for operational monitoring, maintenance, commissioning and optimization are researched.

Project term: 12/2018 – 11/2022; Funding: BMWi Bundesministerium für Wirtschaft und Energie.
