… detta examensarbete har varit att genomföra en nulägesanalys av Hall 7 på Sapa Heat Transfer AB i Finspång. Utifrån nulägesanalysen togs åtgärdsförslag fram som kan generera en effektivare uppvärmning, mindre yttre utsläpp och behagligare arbetsklimat. Problemet i Hall 7 är att …
In this report a study has been done regarding different heating systems on which are the most comprehensive with solar heating systems. The report has also been focusing if solar power can be used as a primary heating source for supplying more than 50 % of the buildings total …
En undersökning om byggandet av vinterträdgårdar
… will need to have a good ratio between the area and the façade so that the heat losses will be at a minimum. However, due to the fact that one of the sides of the façade is connected to the warm house, you quickly realize that the shape of the conservatory is of no importance …
Är det möjligt med biomassa, solenergi och vindkraft?
… has a high shape factor which indicates that a significant amount of internal heat passes through the climate shell. To meet the passive house demands we would have to give the house a different shape to obtain a lower shape factor which would increase the ability of the house …
… construction elements are described. The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity) are reported so that one can in principle start construction of the house. In addition there are calculations done on the building’s …
… to meet a particular specification. The material should insulate against body heat, be stable, protective and durable. Double weave was chosen early in this report, it is a simple way to influence the textile properties of the material. This in a significantly greater extent …
… those measures that save least energy. Installation of ventilation system with heat recovery (FTX) and exhaust air heat pump (FVP) do not prove to be profitable. The option that provides the biggest profit while saving most energy is a combination consisting of charging for hot …
… MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks. The result also shows that the energy gain from the waste fraction can heat 77 houses for a whole year. The conclusion is that environmental benefits will be greater …
… it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries. This places high demands on the energy …
… has been created where input for different parameters such as insulation, heating and lighting can be varied. The model calculates the energy usage of the different parameters and then translates them into carbon dioxide emissions. The results show that the single parameter that …
… of solar energy has been studied, solar thermal collectors to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building. Result shows that an investment in a solar cell plant for electricity production is the most …
… in to electricity whilst solar thermal collectors convert solar energy into heat, which can be used to heat hot water for households. This goal of this study has been to investigate the possibility of implementing solar energy into the energy system of Kista Galleria, one of …
… residential and service. Of the 40% of the energy consumption was 60% used for heating and domestic hot water. A report from year 2012 shows that one reason why the heating volume is so great could be due to underestimating on the energy consumption for the heating in the …
… source of energy from the Sun's light. Energy can be used to produce both heat and electricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely free to extract, environmentally friendly and virtually maintenance-free …
För att tillgodose den studerande KTH byggnadens framtida krav kommer det befintliga ventilationssystemet att bytas ut. Två olika möjliga värmeåtervinningssystem har jämförts ur fjärrvärmebehovssynpunkt. Det befintliga systemet med vattenburen batterivärmeväxlare har en låg …
