Med avseende på friktion och nötningsmotstånd
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses …
Ett miljöcertifierat gestaltningsförslag med hållbar stadsplanering i fokus
Gävle beräknas inom de kommande åren växa med cirka 500 invånare per år, vilket måste avspeglas i satsningar på bostäder, arbete och service. Fastigheten Skeppsbyggaren, mer känd som Philipsontomten, bär anor från svunna industriepoker och har sedan mitten av 1990-talet stått …
En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren
… source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal …
… target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by …
Denna rapport grundar sig i Svenska Mässans planer på expansion och de krav på effektiv hantering och korta ledtider som det medför. Svenska Mässans unika förutsättningar vad gäller yta, bransch och placering medför ett komplext flöde av material. Flödet försvåras ytterligare av …
… 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 common techniques to harvest solar energy in …
Dagsläge och framtidsplaner
This study focuses on small scale hydropower in Sweden. This means plants with a capacity of up to 10 MW. The study has a special focus on plants with a capacity up to 2 MW. The study has three aims. It strives to describe the small-scale hydroelectric industry in Sweden. It …
Analys av mätningar från byggbranschen
… mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall. For this thesis …
Finns möjligheten till Passivhusstandard för befintliga bostäder
… already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new …
Simulering och jämförelse av gamla och nya system
… with large need of renovation, and they all require a high level of energy efficiency measures. To show how the energy demand increase or decrease depending on the changes chosen to be made, the simulation application IDA Indoor Climate and Energy was used. Simulations were made …
… affects other domains, thereby increasing an enterprise's pro-activity and efficiency. By mapping the EA frameworks available on the market and how an implementation of an EA framework can affect how you work within SL, I give in this thesis a description of how an EA framework …
… vehicles is their lack of waste heat for compartmental heating, due to higher efficiency of the electrical engine and the fact that the energy conversion doesn’t involve combustion. An ordinary diesel-buss can use the waste heat from the engine for compartmental heating, but …
… efficient buildings. There are several advantages of the vacuum insulation. Efficiency and energy savings due to its low U-value are the most important. The disadvantages are the expensive investment, the fragile metal case that is highly sensitive to mechanical damage and a …
