Optimisation and flexibilisation of generation systems for DWH.
Drinking water heating (DWH) in buildings is predominantly centralised and, for hygienic and functional reasons, a minimum temperature must be maintained in the DHW distribution system. In addition to circulation systems, electrical temperature maintenance bands (TMB) are used.
Central heat generation often fulfills a dual function of heating and heat recovery. While proven algorithms are available for the heating due to the correlation to the outdoor temperature, the prediction of the TWE demand is only possible to a limited extent.
In the project, a THB is therefore to be used as a sensor for DWH distribution systems in order to be able to detect the consumption behavior centrally.
For this purpose, an algorithm with AI technologies is to be developed that has predictive characteristics. This is then to be transferred into 2 services: The energetic service has to include optimisation and flexibility procedures for common generation systems, together with data transmission for status recording. The hygienic service aims at detecting and monitoring the risk of legionella growth.
The engineering will be tested using a HiL environment and in a field test. Since the project will act as a satellite project within the thematic network N5GEH, the use of the developed platform (phase I) for the planned services will take place. For this purpose, coordination on interfaces and a reflection of the generally valid services to be developed must be carried out.
