11. Experimental Testing of Solar Photovoltaic/Thermal Collectors for Low Temperature Heat Pump Integration
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : A hybrid photovoltaic/thermal (PVT) collector enables simultaneous electricity and heat production from a single solar module. Integrating PVT collectors with a ground source heat pump (GSHP) improves the seasonal performance of the heating system and prevents from temperature degradation of the ground. LÄS MER
12. Effects of stratospheric wildfire smoke on ozone depleting substances and ozone levels in the northern midlatitudes
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/KärnfysikSammanfattning : The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. LÄS MER
13. TEMPERATURE MODELLING OF GEAR MESH
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Temperature control is an essential aspect of gear design. Continuous research is going on to improve the efficiency of gear systems. Power losses or energy losses in these systems typically manifest themselves as increased temperatures and thus reducing the lifetime and overall performance of the system. LÄS MER
14. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels
Master-uppsats, Lunds universitet/Avdelningen för BrandteknikSammanfattning : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. LÄS MER
15. MODELING ENERGY LOSSES AND GAINS IN LOW TEMPERATURE BI-DIRECTIONAL HEATING AND COOLING GRIDS A CASE STUDY OF E.ON’S ECTOGRID
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Energy for heating and cooling purposes is essential for many industrial processes, as well as something we all rely on to provide us with warm water and a pleasant indoor climate. As much as half of all energy consumed in the EU is used for heating and cooling [1]. LÄS MER
