21. Propane Heat Pump Modelling and Monitoring for System Control Analysis
Master-uppsats, KTH/Tillämpad termodynamik och kylteknikSammanfattning : The objective of this master thesis was the performance analysis of a non-conventional heating system layout based on a propane heat pump unit. The objective had been pursued by monitoring and modelling the system. First, the project focused on monitoring the system, since for a correct modelling it was necessary to have all the data of the system. LÄS MER
22. The electricity demand andsupply in El Espino : Alternatives for diversification of renewabletechnologies
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : The use of alternative fuels, particularly renewable energy sources, has been an important strategy to achieve greenhouse gas emission reductions. In Bolivia, many rural areas struggle with an unreliable power supply. LÄS MER
23. The FLARE Suit: A protection against solar radiation in space
Master-uppsats, KTH/RymdteknikSammanfattning : FLARE Suit är en enhet som används för att skydda astronauter från intensiv partikelstrålning när de reser ut ur magnetosfären på framtida Deep Space-uppdrag. Denna dräkt kan skydda mot solpartiklar som på grund av sin höga densitet kan orsaka akut strålningssjuka och leda till överdriven förstöring av inre organ (mag- tarmkanalen, nervsystemet, blodbildande benmärg) och i värsta fall till döden.

24. Design of an off-grid renewable-energy hybrid system for a grocery store: a case study in Malmö, Sweden
Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskapSammanfattning : On planet Earth, fossil fuels are the most important sources of energy. However, these resources are limited and being depleted dramatically throughout last decades. Finding feasible substitutes of these resources is an essential duty for humanity. LÄS MER
25. Analysis and comparison of weather models for solar irradiance forecasts in Sweden
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : Solar radiation is affected in a variety of different ways through the atmosphere and on its way down to the Earth’s surface. Clouds are the main factor in this attenuation of solar radiation, but aerosols, ozone and other different gases have a significant impact too. Understanding these processes is fundamental to solar forecasting. LÄS MER
