The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

AbstractThe aim of the study was to describe district nurses experiences meeting intimate of cancer patients in home care. The study had a qualitative approach with a descriptive design. The sample consisted of ten district nurses employed in primary health care, working in emergency duty in a district in the Middle of Sweden. The results are presented from the two categories; to communicate and being competent, which was formulated to one theme. The theme ?Being safe in one´s professional role, being aware of possibilities and difficulties when encountering intimates in home care?.

In order to reach the environmental targets, set up by the EU, there are many measures taken to make Sweden more energy efficient. In the housing and real estate sector, an installation of an exhaust air heat pump that reuses the heat in the exhaust air in order to lower the amount of acquired energy, is an example of such an action. The recovered energy can then be used for heating of radiators and tap water. This report aims to evaluate and compare three different systems using exhaust air heat pumps regarding COP, degree of coverage and cost savings. This study was delimited to only account for apartment buildings.The theory chapter describes the different conditions and factors that affect a building?s energy balance.

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish District heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.

Sweden has long had access to low electricity prices due to the wide availability of hydro and nuclear power. This has now changed because of today's rising electricity rates resulting in increasing heating costs for properties, especially in the properties with electric heating systems."Ankaret" is a parish for "Svenska Alliansmissionen", which is located at "Gullbrannagården".The parish has installed electrical radiators and an exhaust ventilation system that makes the energy demand high due to the large ventilation flows. The building was built as the price of electricity was still low and would reduce energy use today by combining its heating system with an air/air heat pump. The heat pump delivers more heat into the room than the electrical energy that it uses. This lowers the electricity needs.

This thesis is largely about museums and their role and development in and for society. With a field/case study of the District Six Museum in Cape Town, we try to encapsulate a modern function for museums within a context of 1) the current worldwide discussion on museums and their future, and 2) the development of a new democratic nation in South Africa, and museums possible role in that process. Through analysis of interviews made with concerned people within and outside the District Six museum weintend to get a picture of the views on this particular museum and its role and function, for its community and society at large, plus for other museums, as a possible role model. We find that this museum might be close to a type of museum that has been asked for by museologists and others in recent times..

The district nurses' duties with all organisational changes, above all during the last 20 years, have been changed. Economy and listing governs which visits that to be prioritized. The aim with this study was to examine what district nurses in the primary care in Uppsala län has for view about their occupational role. The method was qualitative and the selection comprized ten district nurses in Uppsala län that were interviewed individually on the basis of a semi structured interview guide that the authors the actual created. In the wide analysis of the results could a theme, As a rubber screw in a shrinking hole and three central categories be discerned, Occupational role, Diversity and Organisation.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

This Master?s thesis is about the public library development in a rural district, in this case Bergunda, a large rural district in Kronoberg?s County in Småland in Sweden, existing 1952 ? 1970. The main question is; how the public library develops in Bergunda large rural district 1951-1970. The main question is divided up in sub-questions: the district uniting in 1952 and 1971; personnel; lending; library housing and the public library structure. In 1952, there is one public library, Bergunda public library, and four study circle libraries.

Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.

The Swedish Government has set a target to reduce energy consumption through energy efficiency within the construction and real estate sector. The purpose of the study is to examine how energy efficiency within this sector could affect the District heating volume in the future, on basis of Vattenfalls District heating system in Uppsala.An Excel model has been created to study how energy effficiency measures affects District heating demand in buildings by 2045, based on technical and economicalconditions. Furthermore, an interview study has been conducted to examine incentives for District heating customers to invest in energy efficiency measures.Result of the Excel model shows that the District heating volume of Vattenfall in 2045 is expected to 931 GWh, which corresponds to a volume decrease of 10,6 %. Based on the study?s theoretical framework only 15 %, 1 024 GWh, of the technical-economical potential is assumed to be implemented.
