… When added in a product, it does not affect the viscosity or taste and it is heat and acid stable. Three different fiber levels were added to ProViva Mango; 5 g, 10 g and 15 g/350 ml and they were compared against a reference beverage without added fiber. ProViva has a shelf …
… have been studied. In energy performance calculations, where internal heat gain parameters are unknown, template values that, in a reasonable way represent the activity in the room, are necessary. These values can be used as input data for whole-year calculations, or for …
En undersökning av energieffektiva fönsters påverkan på byggnaders energiprestanda
… an office building and an apartment building. The conclusion is that the heat gain coefficient shown to have a major impact on the energy performance of buildings. This questions the Swedish energy labeling system that only takes into account the window's U-value. During the …
<em>Genom användning av byggnader som värmelager</em>
Ett vanligt problem för fjärrvärmeföretag är svängningar i den dagliga efterfrågan på fjärrvärme. När efterfrågetoppar sker i fjärrvärmenätet behöver fjärrvärmeföretagen oftast använda sina topplastpannor, vilka vanligtvis drivs på både dyra och miljöovänliga bränslen. Ett sätt …
Undersökning av Ungerns energisituation inriktat på geotermi samt kapacitetsfaktorn för det största geotermiska värmeverket i Mellaneuropa.
… One of the major investments implemented was to build the largest geothermal heating plant in central Europe, located in Miskolc. This degree theses aims is to raise the capacity factor for this heating plant. To achieve this objective, a survey of how grain dryers and …
En analys av åtgärder som kan förbättra energiprestandan i flerbostadshus
… other projects. The main methods examined were ventilation systems utilizing heat exchangers, energy efficient windows and glazed balconies. Based on cost efficiency and amount of energy saved, the results were then evaluated and compared to one another. This showed that the …
Potentiell besparing i fjärrvärmesystem
… is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with …

… building are also presented. The analyzed systems are pellet boiler, solar heating and two types of pre-heating/pre-cooling of ventilation air with ground heat. The most viable of these alternatives were the pre-heating/pre-cooling of the ventilation air with underground ducts …
En studie av borrhålets temperaturinverkan på värmepumpens värmefaktor
Sverige har en hög andel installerade bergvärmepumpar, som är en typ av vätska-vatten värmepump. Ett problem som finns för befintliga bergvärmesystem är att berget med tiden kyls ned då returslangen till borrhålet konstant levererar kyla till berget. Till följd av detta mister …
