… considered are based on either electricity generation by solar cells or heat generation by solar water heaters. Different uses of the obtained energy are discussed ” grid-connected systems, local direct current systems and heating of tap water. The results show that two …
… cells is the type of energy produced by the system. Solar collectors generate heat, while solar cells generate electricity.Analysis of the different systems shows that solar collectors can supply the entire domestic hot water need, during the summer, in the Royal Seaport. While …
… to prove profitable. An examination of ways to produce electricity and heat in a cogeneration plant could provide a better outcome.
Test av olika råvarumixer i pelletstillverkningen vid Rindi Västerdala AB:s bioenergikombinat i Vansbro
… bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of …
… because of thehigh energy cost relative to the available living space. The heating cost today is around 1 400SEK/m2 and per year, this includes the kitchen area and the engine compartment of 38 m2. Thisreport will through thermo graphical and an analysis of Vista’s heating …
… comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant. This was calculated to 8,24 MJ/kWh. The total …
… this case. The local conditions are not sufficient for generating cooling with heat energy. It was found that the optimal technique for increasing energy efficiency was to decrease the condensing temperature for the existing compressor systems. Two eligible ways of doing this …
Simulering och jämförelse av gamla och nya system
… pool covered or not covered during the night. The biggest difference in heat demand was found to be in the two extreme cases, and the use of recirculated air has the highest impact.
… project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process) …
En utredning om åtgärder på en industrifastighet
… to reduce the energy consumption within the industrial building enve-lope, the heating systems and lighting are being investegated. A good building envelope emits less heat and thus reduces the energy consump-tion. An energy audit is a tool used to determine the energy loss. A …
… and solar energy. Solar collector makes use of solar radiation and serves to heat water for further heating of the house. The solar panels have a very poor energy efficiency during the winter months, which necessitates an additional energy source. A pellet boiler is a great …
Stegen till att eliminera radongas med rätt Grundläggningsmetod
… In addition that home should be safe, it should also protect one against heat, cold, sunlight and pollution. The indoor environment is affected by installations, material and how the building is formed. Those anomalies that are visible, felt or smelled can be noticed and be …
… a long time. Three reinvented methods to modify wood and its properties are heat treatment, acetylation and furfurylation. This work examines the durability problems that occur to wood used as façade material, and methods for increasing the durability are identified. By …
Planering av belysningsanläggning i mekanisk verkstad
In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting …
Det här är ett examensarbete som handlar om en fastighet som står på Norra Kungsgatan 37-43 som har både en värmepump och fjärrvärme för uppvärmning. Värmepumpen används i första hand och fjärrvärmen används som spets när värmepumpen inte räcker till. Detta är en ganska ovanlig …
