1. 1. Predicting inflow and infiltration to wastewater networks based on temperature measurements

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Martin Åsell; [2024]
   Keywords : Inflow and Infiltration; I I; CNN; Linear regression;

   Abstract : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. READ MORE

3. 2. Improvement of anautomatic networkdrawing algorithm in thecontext of utility networks

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Hyacinthe Ménard; [2024]
   Keywords : District Heating Network; Mathematical Optimization; Python; Fjärrvärme; Optimeringslära; Python;

   Abstract : The European Union’s ambitious climate targets necessitate substantial reductions in greenhouse gas emissions, particularly within the heating and cooling sector, which accounts for a significant portion of energy consumption. District Heating and Cooling (DHC) systems emerge as a key solution for decarbonizing this sector by enabling high efficiency heat production and the integration of renewable and carbon-neutral energy sources.

4. 3. Integrating Waste Heat from Hydrogen Production Into District Heating

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Fawzi Kayali; [2023]
   Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

   Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

5. 4. Techno-economic analysis and simulation of low temperature district heating networks

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Author : Ilia Iarkov; [2023]
   Keywords : Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

   Abstract : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. READ MORE

6. 5. Commissioning of ITER heat rejection system for low load

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Elizaveta Yakovleva; [2023]
   Keywords : commissioning; ITER; fusion; control logic; cooling system; I C;

   Abstract : This project has commissioned the control logic of the Heat Rejection System (HRS) at ITER, the international fusion project. The HRS is a large system, including 10 cooling towers, 13 pumps, and pipes large enough for a water flow of several thousand kg/s. All of this will becontrolled with automatic control logic.
