6. 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
7. 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
8. 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
9. Rolling bearing lubrication at low temperature
Sammanfattning : Problems connected with rolling bearings at low temperatures are high starting and running friction, concerns about the presence of a lubricating film and the degree of roller slip at low-temperature start-up. Also, questions have been raised whether the high shear stresses in a grease sheared at low temperature could cause thickener degradation. LÄS MER
10. Low Temperature Charge Transport in Diamond
Sammanfattning : Diamond is a wide band semiconductor with fascinating electrical and physical properties. It has high thermal and electrical conductivity, high electrical breakdown field, high radiation hardness and is chemically inert. LÄS MER
