HydAb – Increase of comfort and efficiency by new concepts for hydraulic balancing of heat distribution in residential buildings

The importance of hydraulic balancing of heat distribution systems for energy-efficient building operation and resident comfort has long been recognized. Nevertheless, it can be stated that there is a lack of expertise and still far too often insufficient implementations occur in practice. Companies have also noticed this gap and have developed new products or solutions. The aim of this research project is to investigate how well and reliably these solutions for automatic hydraulic balancing work, and what benefits they provide in terms of comfort and energy efficiency. For this purpose, the products will be installed in real systems and tested by means of a hardware-in-the-loop procedure. The effects on a virtual building modeled in detail can be tracked and evaluated in real time. The results are presented to the professional community in the form of factsheets that enable an independent comparison.
