    Master-uppsats,

    Författare :Raghu Lakshman Gundra; Jagadeesh reddy Medapati; [2021]
    Nyckelord :CFD anlysis; Heat exchangers; Heat transfer analysis; Heat equation temperature; Temperature equilibrium.;

    Sammanfattning : A heat exchanger is a device used to transfer thermal energy between two or more fluids, at different temperatures in thermal contact. They are widely used in aerospace, chemical industries, power plants, refineries, HVAC refrigeration, and in many industries. LÄS MER

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

    Master-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet; Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Pranjal Jain; Khaled Alturkmani; [2021]
    Nyckelord :Wastewater; Heat Exchangers; Heat Pumps; Biofilms;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : The European Green Deal declared that Europe must decarbonize to become carbon-neutral within 2050. To do so, the European Parliament emphasized hydrogen as a major tool for energy transition. In regard of current environmental challenges, liquid hydrogen has raised interest as energy carrier for energy storage and transport. LÄS MER

    Sammanfattning : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A. LÄS MER
