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. Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry : Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator
Sammanfattning : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. LÄS MER
3. Some Factors Influencing Thermal Comfort and Air Quality in Residential Buildings. Field Measurements and Laboratory Tests
Sammanfattning : The main prerequisite for applying a specific ventilation system in residential buildings is that the demands set upon the indoor air quality and thermal climate can be satisfied. If this cannot be guaranteed using a simple exhaust system, a system with treated supply air, i.e. balanced ventilation, should be considered. LÄS MER
4. 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
5. Low-Temperature Heating and Ventilation for Sustainability in Energy Efficient Buildings
Sammanfattning : In 2013, the building sector consumed approximately 39 % of the total final energy use in Sweden. Energy used for heating and hot water was responsible for approximately 60 % of the total energy consumption in the building sector. Therefore, energy-efficient and renewable-based heating and ventilation systems have high potential for energy savings. LÄS MER
