Abstract
Saving energy is a topic that has become part of everyday life in recent years. In the construction sector, this aspect has already been embedded in law for some time by means of OIB Guideline 6 "Energy Saving and Thermal Insulation". Domestic energy losses must be minimized or recovered as far as possible. Numerous technologies are already available for a wide range of energy types and sizes.Energy recovery from wastewater has not yet been established on a large scale. Numerous research projects can already be found with the problem that content from the documents can
be retrieved at the element level or from the scale of a small housing estate. It is not possible to find a domestic solution on the scale of a single-family house. The aim of this work is to open up this research gap and to provide data in the area of energy extraction performance.
The approach in this elaboration begins with comprehensive research. Information from this is used to form two research bodies and to extract influences. This is followed by a two-stage investigation of the models using CFD simulation. First, the effects of individual influences are analysed. The bodies are then modified based on the new findings and analysed again. The outcome is the range of extraction capacities from the models. The analysed systems are compared economically with existing technologies. The challenge was to select appropriate solution approaches and boundary conditions that sufficiently reflect reality and can be processed with moderate calculating time.
The data obtained from the study shows that the second research body may have significant potential for energy recovery. The integration of a heat pump into this system can be useful. From an economic point of view, the application of the analysed technology may offer an advantage over existing solutions.
