1. 11. Normalization of Cooling Demand in Buildings, development, and evaluation of methods

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

   Author : Xingtong Wu; [2022]
   Keywords : ;

   Abstract : Because of the increasing demand for indoor thermal comfort and the better insulation performance of building envelopes, cooling demand is an increasingly important part of building energy consumption despite the cold climate in Stockholm. Finding a way to normalize cooling demand to climatic conditions will help better energy audits to improve the building performance to achieve energy-saving. READ MORE

3. 12. Optimization of district coolingsystems : A case study in a Swedish industrial setting

   University essay from KTH/Energiteknik

   Author : Siri Sinimaa; [2022]
   Keywords : ;

   Abstract : Energy utilization as well as heating and cooling specifically constitutes a large share of the energy consumption in the EU. Reducing greenhouse gas emissions in this sector is thereby of importance to mitigate climate change and fulfill the criteria stated by the Paris Agreement of limiting the increasing global mean temperature to 1.5 °C.

4. 13. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

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

   Author : Haoyang Dong; [2022]
   Keywords : borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE

5. 14. Oil Autonomy of a Turbojet

   University essay from KTH/Flygdynamik

   Author : Florian Steiner; [2022]
   Keywords : Fluid Mechanics; Turbojet; Oil circuit; Fluid Mekanik; Turbojet; Oljekrets;

   Abstract : The oil circuit of a jet engine is required to lubricate and cool mechanical parts. The oil is pumped from the oil tank and flows through heat exchangers. Then it is injected on the bearings for lubrication and cooling, before being scavenged at the bottom of the sumps and finally flows back to the oil tank. READ MORE

6. 15. Data center cooling solutions : A techno-economical case study of a data center in Sweden

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

   Author : Joel Sjökvist; Fredrik Magnusson; [2022]
   Keywords : Energy systems; Data center cooling; Free cooling; Air cooling; Geothermal cooling; Mechanical cooling; District cooling; Building conversion; Dry cooler; Cooling machine; Borehole; PUE;

   Abstract : Given the coinciding growth-trend in the production of consumer electronics and generation of data, the increase in server halls and data centers, as a means for hosting storage capacity for the generated data, has been prominent over the last decades. The establishment of data centers in already existing infrastructure can entail major changes in terms of energy system design. READ MORE
