En studie med syftet att lösa energibehovet för ett specifikt hus.
… all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to …
… and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil. Fuel costs for oil and coal were compared with the …
… of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most …
… make 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 …
… demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat. This technique involves a reduction in electricity consumption compared to …
Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state. In recent years Vaporel AB has introduced a new tecnique that gives an external …
tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
A third party access to district heating networks has been proposed in Sweden, to increase the competition on the district heating market. Such third party access could create opportunities for the agricultural sector as an energy producer. This study describes the technical …
? en värdering av miljöeffekter
… for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared …
Ett samarbete mellan ÅF och kund
… program from NIBE was also used for comparison. The results showed that a district heating price of 0.80SEK/kWh is needed in order for this measure to become profitable. The second study was about presence control of lighting in a museum that was part of an ongoing Energy …
En studie av två verkliga byggnader
… and that the future price on electricity will be double the price of the district heating. The investigation also exhibited the known fact that the smaller building is the more effective for the climate shell in optimum. This property gave more reliability to the whole …
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 …
… space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases …

… space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases …
… heating. I have chosen to compare tree different alternatives for small district heating with straw as fuel. In two of the alternatives the plant is being fed by batches of straw in big bales in the third alternative the plant has a straw chopper and continues straw feeding by …
… snow-cooling and air blast cooler) are compared with today’s systems (districts heating and compression cooling machines) with respect to environmental impact and economy. District heating and diesel generator with rape seed oil are systems with negative global warming …
