Energimässig jämföelse med investeringskalkyl av två förskolor

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.

Kalcium- och fosforsmältbarhet hos växande hästar

In the latest edition of NRC (2007) the feeding recommendations for Ca and P to growing horses were increased with 35 and 25 %, respectively, based on results from a Canadian study showing that daily endogenous fecal losses of Ca and P were greater than previously suggested. A Ca absorption efficiency of 50 % is used for all horses. However, the true absorption efficiency might be as high as 70 % in young horses. P absorption efficiency is assumed to be higher for growing horses because their diets are often supplemented with inorganic P. Thus, an efficiency of 45 % is used for growing horses as compared to 35 % for mature horses.

Hantering av kugghjul : -Vägen från mjukbearbetning till hårdbearbetning

AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.

Akustisk design av studiorum för musikinspelning

Detta projekt genomfördes i samarbete med akustikern Erling Nilsson på företaget Ecophon i Hyllinge. Uppdragsgivare var musikproducenten Magnus Ågren som äger studion Flow Music i Malmö. Uppgiften var att förbättra akustiken i ett av Flow Musics studiorum. Rummet hade före projektet en hård och obehaglig akustik. För att komma fram till ett åtgärdsförslag specificerades först hur enskilda akustiska egenskaper skulle påverkas för att ge ett så bra resultat som möjligt.

Konstruktion av balanseringsutrustning

Syftet med arbetet är konstruera en balanseringsutrustning för pump- och fläkthjul åt Billerud Karlsborg. Det finns en balanseringsutrustning på företaget idag, men den klarar inte av alla dimensioner på pump/fläkthjulen varför en bättre lösning vore önskvärd. Målet med det här projektet är att kunna presentera en lösning på en balanserings utrustning i form av ritningar på själva stålkonstruktionen samt ett förslag på hur drivning av utrustningen skall ske. Därmed skall projektet tillhandahålla Billerud med tillräcklig information för att en ny balanseringsutrustning skall kunna tillverkas. Utrustningen bör klara av att balansera rotorer med en vikt på upp till 250kg och en största diameter på 1500mm.

Gynnar eller motverkar kommunerna kostnadseffektiv miljöstyrning : en studie av kommunala taxor och avgifter

Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals. The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.

Värmeslag hos hund : Förebyggande åtgärder, djurägarråd och omvårdnad

The objective of the essay was to identify the nursing care required by a dog suffering from heat stroke and how to educate and advice the owners how to start treating their dog and prevent the condition from occurring in the first place. The essay is based on a literature study. Several databases were searched for scientific research to try find answers to the issues. Keywords concerning the subject were used and mixed in different combinations to sort out the suitable studies. The results of the study indicate that the dog should be cooled by the owner directly after detection. The most crucial issue is to reduce the body temperature as quickly as possible or the morbidity will worsen.

Försäljning av närvärme :

To provide our company a new business opportunity I have in this essay examined the economical possibilities to sell energy. I have chosen to do a case study on my own farm in this essay. The farm is focused to cropping and also have some properties for hire. The farm is situated in the village of Fjelie and that?s where the opportunity for selling heat are. Fjelie has about forty houses. The idea is to build a plant where straw is being used as fuel.

Energieffektivisering genom förvärmning av flis till kokare med sekundärvärme

The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.

Hållbarhetsaspekter på tillvaratagande av spillvärme i borrhålslager- ur ett företags- och samhällsperspektiv

The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.
