Inverkan av värmesystem på termisk komfort i ett flerbostadshus med hänsyn till energianvändning

Inomhusklimatet har en avgörande roll för människans hälsa och välmående då människor befinner sig inomhus i nästan halva sitt liv. Det finns flera aspekter till hur det ska erhållas ett bra inomhusklimat men de mer betydelsefulla aspekterna är både god luftkvalitet och termisk komfort. Samtidigt som innebörden av reducering av energianvändning har en viktig roll i dagens utveckling. Då det ständigt arbetas med att försöka reducera energianvändningen i syfte till att underlätta för miljö- belastningen, väcker det frågor om hur den termiska komforten påverkas av detta.Rapportens syfte kommer därmed ligga i identifikation av uppvärmningssystem för ett givet flerbostadshus i Stockholmsområdet med fokus på termisk komfort och energianvändning. Utvärderingen baseras på olika typer av inverkan från diverse system som har utförts med beräkningssprogrammet IDA ICE.

Boken ? ett stöd i livets slutskede

This is a study of the importance of culture for persons who are in their terminal stage of life. The purpose of my study is to find out if culture, particularly literature, can be a comfort for persons who are about to die. The study is based on interviews with people who are working in the palliative team at Norra Älvsborgs Länssjukhus (NÄL) in Trollhättan. It is also based on study of literature. It is literature about hospital library, culture in hospital treatment, palliative care, bibliotherapy and ?own stories? from dying persons.

Miljöbetong

The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the 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 10-20% after insertion of individual metering and charging in an apartment block.

Termisk energilagring i borrhål : 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 systemet en betydande del av sin verkningsgrad samtidigt som det i extrema fall kan leda till permanent isbildning i borrhålet.Ett sätt att motverka detta problem är att tillämpa termisk energilagring i bergvärmesystemets 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.

Intern marknadsföring i tjänsteproducerande företag

This thesis discusses how companies work with internal marketing to increase personnel motivation and comfort, and how internal marketing and employee rewards are valued by companies? management. Issues addressed include: the link between employee satisfaction and the success of companies: how to work successfully with internal marketing: the value of different kinds of rewards for personnel: the importance of communication and information. By studying literature and theories about these issues and also interviewing personnel managers in two different companies we have learnt that companies use internal marketing with awareness and thought. We also learnt that company leaders value employee rewards very high, although there is a different in what sort of rewards they value the most..

Konvertering från luft till vätskekylning av elektronik

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

Kontokortsbaserade betalningssystem på Internet

Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

Nytt ventilationssystem till djurstallar :

There is two dairy farms in Sweden with ability to be opened on both long sides, one outside Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results or not enough literature about natural ventilation and especially on this kind of air inlet, makes my tests very interesting not only on Alnarp, but among other companies. I would like to find out if there is any air movements direct on the cows, how high/low temperature, air humidity, light intensity and noise standard inside the barn. Does Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could this system become the new dairy barn instead of the conventional barns in Sweden? I am going to focus on the animals environment, after all they are the one who is going to spend the most of the time in the barn. I used five electrical loggers distributed inside the barn to measure the temperature and one of the loggers measured the air humidity, every 15th minute. One logger were placed on the outside which measured both temperature and air humidity.

Vinterträdgårdar ur ett byggperspektiv : En undersökning om byggandet av vinterträdgårdar

The purpose of this of this essay is to explore the construction of a conservatory that is livable allyear around. When you build a conservatory there are several factors that need to be regardedthat usually are of no importance when you build a regular conservatory. The glassed facadeneeds to have a very good U-value and all the parts of the facade need to be isolated and theconstruction needs to prevent thermal bridges.In this essay we will start by looking at the shape of the conservatory. Due to the façade consistsof glass the conservatory will need to have a good ratio between the area and the façade so thatthe heat losses will be at a minimum. However, due to the fact that one of the sides of the façadeis connected to the warm house, you quickly realize that the shape of the conservatory is of noimportance.There are two common ways to build a foundation for a conservatory, a molded concretefoundation and isolated wooden beams.

Att bygga i trä eller lättbetong : en jämförelse mellan väggkonstruktioner

Hudiksvall Municipality will build a new preschool. The goal is that the pre-school should reflect the municipality's environmental goals and meet building regulations. The wall structures that are compared in the report is an insulated wooden frame and a frame of lightweight concrete blocks from H + HWall structures are compared within the areas of U-values, air tightness, thermal storage capacity, fire ratings, moisture, durability, emissions and environment. In these categories the two wall structures will be rated in a scale from 1 to 5 and then the categories are weighted against each other. The weighting is based on Hudiksvall Municipality's assessment of the categories importanse for their final selection.The results of the comparison show that the concrete structure is recommended for the construction of pre-school with 27.55 points against the wooden structures 23.70 points.

Bildernas byggstenar : En studie om pixlar och vektorers egenskaper i form av digitala material

With a new digital world that runs parallel with our physical one, we are also facing a new type of architecture and new materials that this new architecture is built on. In this thesis I examine pixels and vectors, two of the digital materials used to create pictures. By approaching them as digital materials, I have mapped their different qualities, when and where one or the other is more or less applicable and the reason behind it. My main research question asked was the following: Are the (digital) materials challenged outside their primary fields of application, and in that case, in which way? With this question in mind, I carried out a semiotic picture analysis on four pictures, later on dividing them into four different categories, based on their different qualities and their ability to deliver information.
