   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

3. 2. 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)

   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

4. 3. 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

5. 4. Modelling the performance of heat pump systems for single-family house applications

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

   Author : Mar Coronado Pons; [2019]
   Keywords : ;

   Abstract : Ground source heat pumps (GSHP) extracting the heat through borehole heat exchangers (BHEs) are an extremely efficient way to provide heating. Their performance is affected by the temperature of the thermal source: the ground; the higher it is the temperature of the ground, the higher their performance. READ MORE

6. 5. Monitoring of a heat pump system using deep borehole heat exchangers

   University essay from KTH/Energiteknik

   Author : Baptiste Delattre; [2018]
   Keywords : ;

   Abstract : Sweden has been one of the first countries in the world to use ground-source heat pumps (GSHP) to supply heating and cooling to its buildings. Today, it is the leading country in Europe and new installations tend to have larger capacities. READ MORE
