1. 16. Performance Evaluation of Ground Heating and Cooling Systems - Long-term performance measurements of two case buildings

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

   Author : Hao Liu; Hongyi Zhang; [2020]
   Keywords : Ground source heat pump GSHP ; System performance; Long-term monitoring; Geothermal; Borehole heat exchangers; Office building; Uncertainty analysis; Deep Green Cooling; Free cooling; Heating; Cooling; Technology and Engineering;

   Abstract : Geothermal energy is one of the oldest and most sustainable energy sources and has been used for thousands of years. The temperature of the ground at shallow depth is fairly constant, above the air temperature in winter and lower than the ambient temperature in summer. READ MORE

3. 17. Techno-economic assessment of CO2 refrigeration systems with geothermal integration : a field measurements and modelling analysis

   University essay from KTH/Energisystem

   Author : Fabio Giunta; [2020]
   Keywords : CO2 Refrigeration; Supermarkets; Heat Recovery; Geothermal Storage; Energy Efficiency; Boreholes; Techno-Economic Assessment;

   Abstract : Several CO2 transcritical booster systems in supermarkets use the potential of integrating geothermal storage, enabling subcooling during warm climate conditions as well as being a heat source during cold climate conditions. First of all, field measurements of one of these systems located in Sweden were analysed with particular focus on the heat-recovery performance. READ MORE

4. 18. Utilizing geothermal heat and membrane distillation for sustainable greenhouse horticulture in Alberta, Canada: a multi-criteria analysis

   University essay from Uppsala universitet/Naturresurser och hållbar utveckling

   Author : Rachael Gradeen; [2020]
   Keywords : Geothermal development; membrane distillation; EWF nexus; sustainable development; energy transition;

   Abstract : Growing populations are contributing to resource scarcity, making it ever more important for governments to address resource challenges in a holistic and integrated manner. Energy, water and food are examples of these critical resources, and the province of Alberta in Canada faces an interesting opportunity to tackle all three in tandem. READ MORE

5. 19. A Numerical Analysis on the Effects of Using CO2 as a Driving Fluid for a Geothermal Plant

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : David Bennich; [2020]
   Keywords : reinjection; two-phase flow; geothermal energy; CO2 sequestration; iTOUGH2; ECO2N; återinjektion; tvåfasflöde; geotermisk energi; koldioxidlagring; iTOUGH2; ECO2N;

   Abstract : To limit the effect of global warming society needs clean energy sources and to reduce emissions of greenhouse gases into the atmosphere. By combining carbon capture and storage technologies together with geothermal power production it is possible to gain fossil free energy while potentially storing CO2 at the same time. READ MORE

6. 20. Sensitivity Analysis and Optimization of the Vertical GSHP (Ground source heat pump)

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Sriram Ramanathan; [2020]
   Keywords : GSHP; Borehole heat exchanger; Geo-thermal energy.;

   Abstract :   GSHP (Ground source heat pump), uses geothermal energy which is a form of green and sustainable energy.  Geothermal energy is also a continuous source of energy, unlike wind energy. The results from this thesis work will be applicable for both GSHP that are being used for space heating, and the ones which have a bottom organic Rankine cycle. READ MORE
