En utvärdering av 500 °C isotermmetoden
… cell can be divided into the growth stage, the fully developed fire and the cooling phase. The duration of each phase, as well as the temperature, is dependent on a number of factors, e.g. the fire load, the size of openings and the geometry of the fire cell. In the Eurocodes …
… where the most energy loss occurs as result of heat losses in the exhaust and cooling systems. By recovering and converting the thermal energy of a combustion engine to mechanical/electric power the efficiency of the combustion engine can be increased. In this work the …
a design proposal for Magomeni garden, Dar es Salaam, Tanzania
… gains, increased biodiversity and air quality, improved water management and cooling effect. With urbanisation and the importance of urban parks in mind, this master’s thesis explores the context and development of a re-design of Magomeni Garden. Magomeni Garden is a …
… to shade did not affect the milk production but it seemed as the shade had a cooling effect on the cows which was demonstrated by the results of lower fur temperature and respiration rate for the cows with access to shade. Even though the study did not verify the importance of …
… process. A total roundtripefficiency of the system was alsocalculated. Two cooling alternativeswere examined in the model, an opencycle and a closed cycle. The resultsshow that the most effective systemoption includes waste heat in both thecharging and discharging process …
Termiskt klimat, energianvändning och höjning av certifieringsnivån
… how the different solar shadings: blind, marquis and fixed screen affected the cooling need of the second floor of the preschool. Possible actions for increasing the inlet of daylight are discussed. Two measures were identified: increasing the glass area and changing to windows …
… different fats. Differ-ent amounts of water were absorbed during the water cooling. The fat C cheese absorbed significantly less water than the other cheeses. The cheese made of fat C was significantly harder than the other cheeses. The springiness as well as the cohe-siveness …
En approximativ beräkningsmodell för årliga utsläpp av kylvattenkemikalier ifrån världshandelsflottan
Fartyg använder sig av stora dieselmotorer för framdrift och för att producera elektricitet ombord. Motorerna samt diverse kringsystem har behov av kylning och till detta används kemikaliebehandlat vatten i ett slutet kylsystem. Vid tömning och läckage från systemet tenderar det …
En jämförande fallstudie på Swecos kontor i Stockholm, Göteborg och Malmö
… The optimal choice of window glass is a glass with a low g-value during the cooling season and with a high g-value during the heating season.
Kartläggning,injustering och varvtalsreglering
De flesta industrier har någon typ av kylsystem som betjänar industriella processer och komfortkyla. Funktion och effektivitet på systemen varierar och när kylproblematik uppstår på anläggningen kan anledningarna vara flera. Kylproblematiken kan bero på bristande kylkapacitet …
… filled with sediment as fast as possible and then sealed and put in a cooling bag during the 8 hour transport to Umeå. In the laboratory, samples where homogenized in a N2-filled glove-box and divided into sub-samples for determination of total concentrations of Hg-tot, MeHg, C …
… Manuals of adjustments to the sprayer? Rapid couplings to the warmth- and cooling hoses? Eliminating the work of adjustment when changing the ladle? Introduced a combined spanner- torque wrench? Manuals to the mechanical lockThe total theoretical improvement of these measures …
