1. 1. 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

3. 2. Heat recovery from vacuum brazing furnaces

   University essay from Lunds universitet/Avdelningen för Installations- och klimatiseringslära

   Author : Oliver Robertsson; Rasmus Wikman; [2023]
   Keywords : Waste heat; Vacuum furnace; Heat recovery; HVAC; Technology and Engineering;

   Abstract : By partly replacing the use of primary energy sources with waste heat recovery, climate and environmental goals for the future will be closer at hand. This thesis investigates the waste heat potential of Alfa Laval's vacuum brazing furnaces in Ronneby and alternative ways of integrating the furnace's waste heat into the building's HVAC system.

4. 3. Investigation of new refrigerants for a large-scale heat pump and evaluation of system performance

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Hanna Grahn; Matilda Eriksson; [2023]
   Keywords : Large-scale heat pump; refrigerant; COP;

   Abstract : Heat production accounted in 2021 for 50 % of the energy end use globally, where a strongconnection to fossil sources still exists. Large-scale electrical heat pumps can therefore have akey role in the energy system to enable a decreased reliance on fossil fuels and at the same timecontribute to stable system when incorporating more intermittent renewable sources.

5. 4. Refrigerant Selection for District Heating’s Large-scale Heat Pumps

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

   Author : Görkem Balyaligil; [2023]
   Keywords : heat pump; district heating; refrigerant; natural; synthetic;

   Abstract : The global demand for heat as the primary source of final energy underscores the urgency of decarbonizing the heating sector to foster sustainability. Heat pumps are crucial in achieving sustainability, particularly in district heating applications, offering efficient centralized heating solutions. READ MORE

6. 5. Water born cooling of closed greenhouses : An enclosed vertical water curtain cooling system

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Ahmad Kamal; [2022]
   Keywords : Greenhouses; Water born cooling; Enclosed water curtain; radiative cooling; Surplus heat energy;

   Abstract : The greenhouses play a key role in food sustainable production, the purpose of the greenhouses is to make an artificial suitable environment to grow different kinds of plants. The cost of energy used in the greenhouses to ensure the optimum temperature, humidity, and CO2 concentration, makes up a large part of the final cost of food. READ MORE
