  5. 5. Improving the Efficiency of Thermal Energy Usage in Residential Buildings by Heat Recovery from Wastewater

    University essay from Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet; Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Author : Pranjal Jain; Khaled Alturkmani; [2021]
    Keywords : Wastewater; Heat Exchangers; Heat Pumps; Biofilms;

    Abstract : This study aims to rationalize the consumption of thermal energy in residential buildings by recovering heat from wastewater inside the building before entering the central sewage network outside the building, by conducting an analytical study for a residential tower in Syria to find out the coverage percentage of the heat energy recovered from wastewater for the heating and domestic hot water loads needed for the tower, and calculating the percentage of reduction in carbon dioxide (CO2) gases. It is a simple technology as the thermal recovery system consists of three main components, which are in order: a wastewater tank, heat exchangers, and a heat pump. READ MORE
