… in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower …
… power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would …
… selected for the production of the air heat exchanger. Basedon measured data, electric power (SFP) was calculated for the prototype. The resultsshowed that air heat exchange system was non electrical efficiency because theestimated SFP value was too high. This is probably …
… on circuit design and theoretical explanations of the origin of noise in electric circuits. In addition there are discussions on factors to consider when designing a PCB and the importance of choosing the right component for the right application. Finished PCB-designs for both …
Förslag till handlingsplan för minskad elanvändning på Renovas anläggning i Göteborg
This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the …
… where the compared systems purpose is to be independent of direct using electricity. A system of this design is regarded as sustainable according to environmental as economic issues. The following heating systems have been analyzed in combination with solar energy; Geothermal …
… may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer. Based on the theoretical analyzes of possible faults, it is considered that the requirement for supplementary equipotential bonding systems for bathrooms …
Fallstudie av elproducerande system på ett handelscentrum
This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the …
- Med möjlighet till återvinning
Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating …
… is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm’s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by …
… and construction of a small wind turbine. * Designing and construction of an electrical system. * Thesis with fundamental facts about wind, wind power and design. The thesis contains basic theory in wind power and the energy systems it can be combined with. Different types of …
Examensarbete Industriautomation
The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea. Uppsala University is closely connected with the company Seabased …
