Originální abstrakt

The manuscript deals with possibility of the sewer heat exchanger placement in the sewerage systems for heat energy recovery. The manuscript also describes the wastewater utilization for heat energy recovery in the buildings. The combination of sewer heat exchanger and heat pump can utilize wastewater low-temperature potential. We developed and constructed sewer heat exchanger prototype based on numerical modeling in STAR-CCM+. Software simulated thermal performance of the system and we compared those data with pilot-plant installation at the wastewater treatment plant. Energy conservation measures are recently being discussed in the wastewater application context. We focused to decrease costs of hot supply water or heating by utilization of greywater heating potential. Greywater is the leftover water from baths, showers, hand basins and washing machines only, what implies that it is free of faeces and urine. Different types of heat exchangers have been modeled on theirs thermal performance. Those data will be confronted with real data from the greywater system application in the building. Furthermore, basic economical evaluation, return of investment analyses and technical recommendation will be presented.
