1. Potential of Ventilation Radiators : Performance evaluation by numerical, analytical and experimental means
Sammanfattning : Energy consumption for heating and ventilation of buildings is still in 2011considered far too high, but there are many ways to save energy and construct lowenergy buildings that have not been fully utilised. This doctoral thesis has focused onone of these - low temperature heating systems. LÄS MER
2. Ventilation and window opening in schools, Experiments and Analysis
Sammanfattning : The objective of this thesis is to study the application of ventilation in schools buildings. A number of studies of the application of different forms of ventilation are presented. The main part of the thesis focuses on window opening in a classroom. Analytical models for calculation of the air change caused by window airing are proposed. LÄS MER
3. Behovsstyrd ventilation i lokalbyggnader-Innebörd och strömningstekniska konsekvenser
Sammanfattning : In todays society energy efficiency and energy savings are becoming increasingly important. The building sector represents a major part of Swedens total use of energy. Furthermore, ventilation constitutes the single largest factor in the energy balance of buildings. LÄS MER
4. ON THE EFFICIENCY OF DISPLACEMENT VENTILATION, with Particular Reference to the Influence of Human Physical Activity
Sammanfattning : The efficiency of room ventilation by the displacement principle was studied with respect to some influential factors, in particular that of physical activity. The study was experimental and performed in two full-scale test rooms, one of office-size and one of classroom-size. LÄS MER
5. Effektivisering av pump- och fläktdrifter i byggnader. Elanvändning och systemlösningar
Sammanfattning : In this licentiate work the energy savings potential by more efficient pump and fan operation in buildings has been examined. The national savings potential in Sweden has been estimated based on available statistics and on information gained in a limited inventory. The estimated energy use for pump operation in residential and commercial (i.e. LÄS MER
