Abstract:
Efficient and clean energy consumption is not only an essential request towards industrial economics. This request also refers towards the residential building sector. There, the major share of energy consumption is caused by house and facility heating. In Germany, most heating systems consist of double-pipe, hot water systems. Due to the lack of hydraulically balanced system conditions, a potential of up to 15% energy savings can be assumed. This paper addresses the use of KNX-technology (Smart Buildings) in residential buildings to ensure a dynamic adaption of hydraulic systems performance, in order to increase the heating systems efficiency. Therefor, a procedure of heating system segmentation into hydraulically independent units (meshes) is presented. This structure enables permanent control of adressable, net-based heating valve drivers in order to achieve balanced mass flow distribution over the whole facility. The dynamic hydraulic balance is achieved by positioning these valv
es according to heating loads, that are generated from the temperature settings in the corresponding rooms. The energetic advantages of single room heating control procedures, based on the application FacilityManager, is presented.
