1. Technical solutions for low-temperature heat emission in buildings
Sammanfattning : The European Union is planning to greatly decrease energy consumption during the coming decades. The ultimate goal is to create sustainable communities that are energy neutral. One way of achieving this challenging goal may be to use efficient hydronic (water-based) heating systems supported by heat pumps. LÄS MER
2. Low-temperature Heating in Existing Swedish Residential Buildings : Toward Sustainable Retrofitting
Sammanfattning : As an energy-efficient alternative in cold climate countries such as Sweden, low-temperature heating (LTH) technology has shown promising advantages and shortcuts to contribute to the efficiency of heat supply, as well as to the overall sustainability of building performance. The goal of this thesis is to contribute to the development of methodologies and modeling tools to support sustainable retrofitting in the Swedish housing stock. LÄS MER
3. Influence of waxes on bitumen and asphalt concrete mixture performance
Sammanfattning : This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. LÄS MER
4. Turbo Charged Low Temperature Combustion - Experiments, Modeling and Control
Sammanfattning : Both the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. LÄS MER
5. Zeolite Membrane Separation at Low Temperature
Sammanfattning : The energy consumption of separation processes accounts for a large part of the total energy consumption in chemical industry. Membrane separation processes require much less energy than the currently used thermally driven separation processes and could therefore reduce energy consumption in industry considerably. LÄS MER
