1. Construction and test of a new compact TRT equipment
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : A relevant contribution to sustainable development can be achieved by providing efficient solutions for heating buildings. The use of a heat pump taking heat from the bedrock with the help of a borehole heat exchanger is a common solution in Sweden to accomplish this. LÄS MER
2. Practical evaluation of borehole heat exchanger models in TRNSYS
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : Vertical ground source heat pumps are established and still growing on the global market. The modelling of these systems is important for system design and optimization. This is an active field of research, and many models are often built into system simulation software such as TRNSYS.

3. Technical and market potential of solar PV/thermal modules combined with ground source heat pumps
Kandidat-uppsats, KTH/EnergiteknikSammanfattning : This bachelor thesis investigates the market and technical potential of combining PV-T technology with ground source heat pumps for multi-family housings in Sweden. The basic idea is to first convert ordinary solar panels to solar panels that are cooled which reduces their resistance. LÄS MER
4. Energipålar - Termiskt responstest på prefabricerad energipåle i betong
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)Sammanfattning : Energipålar är grundläggningspålar kombinerade med kollektorslangar som används som vertikala markvärmeväxlare. De har sedan 1980-talet använts i Centraleuropa, och används även frekvent i England. I Sverige har energipålar ännu inte slagit igenom, men de större byggföretagen börjar nu intressera sig för denna typ av grundläggning. LÄS MER
5. Optimization of thermal response test equipment and evaluation tools
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : Nowadays Ground Source Heat Pumps (GSHP) are widely used to provide heating and/or cooling as well as domestic hot water in commercial and residential buildings. The Swedish GSHPs market is the first one in the European Union with more than 378,000 units installed until 2010 according to the Swedish Heat Pump Association (SVEP). LÄS MER
