En studie av borrhålets temperaturinverkan på värmepumpens värmefaktor
… borrhål. Den internationella benämningen för denna teknik är ”Borehole Thermal Energy Storage, BTES”. Rapporten har behandlat en friliggande enplansvilla med ett befintligt bergvärmesystem som tillämpar termisk energilagring i bergvärmesystemets borrhål med solvärme. Två …
In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually …
Materialmodellering med finita elementmetoden
… stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while …
… average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by …

Samtidigt som debatten kring jordens klimatförändring är i full gång har intresset för att miljöcertifiera byggnader vuxit oerhört. För fastighetsägare är det en möjlighet att bevisa för sina hyresgäster och köpare att byggnaden är hållbar. Är en byggnad miljöcertifierad har en …
… of lesions, skin problems, chafing, mane/tail- and coat quality, respiration, thermal comfort, eye- and nostril discharge, hoof health and lameness. The behavioural assessment was performed by a human approach test and an avoidance distance test when the horses were approached …
Modellkonstruktion och Utvärdering med ORWARE
… additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press. All three technologies hadthe potential to deal with technical hindrances of treating certain waste types with anaerobicdigestion.With ORWARE, life …
… from the infrared camera were in turn used to theoretically calculate the thermal losses of the receiver tubes. To investigate the materials durability the materials were subjected to different climates in a climate chamber and all the tests that has been conducted in this …
… the results show that some corals seem to be able to adapt by increasing their thermal tolerance. The question is, however, whether this can happen at the same rate as the rapid development of climate change. The capacity for such adaptation also differs among species, where …
… shifting too much and occurs too often the animals is affected by a negative thermal comfort. At a colder temperature the cows build fur to stay warm. Then the temperature rises and the cows begins to sweat on account of the fur which after a new temperature shift to a lower …
situationen i Sverige och effekter av utetemperaturen. Enkätundersökning och experimentell studie
… study, are difficult to satisfy in many cars and regulations concerning the thermal climate for dogs are difficult to maintain in a stationary car on a warm summer day. A conclusion, therefore, is that a dog owner who leaves their dog in a car on a warm day could be charged with …
… har använts kommer från plattformen TERRA och dess sensor Advanced Spacebourne Thermal Emission and Reflection Radiometer (ASTER). De våglängdsband som analyserats kommer från det synliga röda och gröna ljuset och det nära infraröda ljuset. Eftersom det som finns på marken …
… globe temperature as base. As solar radiation principally always affects the thermal condition for the cow the globe temperature alternative should give a more adequate description. The effect of solar radiation load is also seen in comparisons between air temperature and globe …
jämförelse mellan naturlig och mekanisk ventilation
… still. The purpose of the present study is to improve our understanding of the thermal dynamics at various points within the trailer. The main body of the study comprises a comparison between natural and mechanical ventilation. A commercial pig truck was fitted with climate …
