Energibalansberäkning

Abstrakt -  As energy prices rise, energy-saving in buildings is becoming increasingly important. By applying different construction and installation technologies, to new buildings the energy consumption can be reduced effectively, compared to similar existing buildings. These technical measures are often an investment in the long term and will reduce energy costs significantly. The purpose of this report is to show how to reduce energy consumption in a small house. It is presented in this report that both building's technical saving arrangements (the sealing of a building) and an installation technical arrangement (changing from the F-system to the FTX-system) would reduce energy consumption in newly built detached houses, if compared with a similar existing house but without these technical measures. The report presents also detailed calculations showing how much energy an existing 2-storey house, built in the year 2007 in Eskilstuna, consumes and how much energy would be saved if these corrective measures were applied to a new building. It is also reported how much money would be saved each year over a 10 year period if the measures were applied. The results show that both solutions are a good investment in the reduction of energy consumption and hence the cost involved. Keywords: energy, heat energy, infiltration, FTX-system, free temperature effectively. .

Energikartläggning hos RostiGP i Gislaved

In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.

Träning och manuell behandling för att minska impingementliknande symptom i skuldran hos idrottare? : En systematisk litteraturstudie

AimThe purpose of this study is to investigate whether there is scientific evidence that exercise and/or manual therapy can improve function, in terms of increased mobility and strength on shoulder impingement-like symptoms among athletes. Another aim is to investigate whether these interventions can reduce shoulder pain.MethodA systematic review was conducted in the databases PubMed, CINAHL, PEDro and Amed. A total of thirteen articles were selected for further review and compilation. They were then graded for level of evidence according to the PEDro scale and the Swedish Council on Technology Assessment (SBU).ResultsThe systematic review shows that there is strong scientific evidence that acupuncture and heat can reduce pain in athletes diagnosed with supraspinatus-tendiopathy. There is limited scientific evidence that exercise increases strength, limited scientific evidence that stretching increases mobility and insufficient scientific evidence that a combination of treatments, with both exercise and stretching, reduces pain and increases function in overhead athletes.ConclusionsExercise and manual therapy can reduce pain and/or improve function in terms of increased mobility and strength in athletes with shoulder impingement-like symptoms.

Hur påverkasogräsuppkomsten av jordbearbetning :

Today it is common to spray against most weeds by using very expensive weed-killers. The goal for every farmer is to have as low costs as possible for their use of machines and weed-killers. Therefore it is in everyones interest to find other methods to fight the weeds. Finding a way to reduce the rise and growth of weeds already at the preparation of the soil would lower the number of laps over the field and also decrease the amount of weed-killing dose. Tests show that by harrow in the dark it is possible to reduce the population of weeds with up to 60%, but the normal reduction would be about 20-30%. To verify the results above we made tests by using two different methods of preparing the soil. We tested ploughing and harrowing in daylight and during night. Later we checked the number of different weeds in areas prepared in daylight and during night. By studying the results from the different methods used we found a considerable reduction of some kinds of weeds in areas prepared during night..

Avsättningar i pappersmaskiner : Utbildning och förslag till processförbättringar

Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.

Nautikerns möjlighet att reducera bunkerförbrukningen

The work aims to clarify what nautical officers onboard in today's merchant can do to help reduce bunker consumption during the voyage? The question we have asked ourselves during the autumn term in 2008 much was said about the premium bunker prices, and how the future could affect our daily lives as nautical officer. We felt here that the school had relatively little knowledge of the subject and therefore felt that it would be interesting to identify how it really looks like onboard the ships today. To collect information we contacted 7 Swedish companies that operate with different types of vessels, in order to get a broad picture of the whole industry. For shipping companies we asked questions about how actively they were working on the issue and what methods they used.

Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation

The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

Energieffektivisering och solenergi i en universitetsbyggnad : Undervisningshuset och Biblioteket i Uppsala

Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.

Tankar om plöjningsfri odling :

The margin in crop production is more and more less and it forces the producer to check out how to reduce the cost of establishment of new crop. One way to reduce the cost in establishment is to begin with plough less farming. It saves money and time compares to conventional soil preparation with plough and harrow. Not all soil types are god for plough less farming and should be continued with ploughing (mainly light soil), but other soil types working very well with plough free farming. If you want to success with plough less farming you have to think in new lanes. One of the things you have to think about is to not grow too much cereal after cereal. Low stubble is important when you harvest the crop and also to spread and chop the straw well. I have in this work interviewed some farmers and farm advisers in Östergötland to see which thoughts they have about plough less farming.
