Abstract of thesis

Thermo-hydraulic optimization of heating and cooling systems for non-residential buildings using environmental energy as heat source and sink

This work focuses on the increase of the system efficiency of heating and cooling concepts using environmental energy as heat source and sink. These systems use for example surface-near geothermal energy by means of borehole heat exchangers or ground water wells (primary circuit). The heat distribution to the rooms is carried out by thermal activated building systems (secondary circuit) such as e.g. concrete core conditioning or floor conditioning.
The extensive hydraulic circuits on the environmental as well as on the building side cause high pressure drops resulting in high energy demand for circulating pumps. Furthermore, the heat transformation carried out by the heat pump is responsible for a high energy demand of the building.
This work is aimed at a reduction of the energy demand of such buildings e.g. by means of a) optimizing geometrical parameters of the hydraulic circuits b) efficient use of high efficiency pumps c) smart control strategies for system components as well as the whole system configuration.
