   Sammanfattning : In recent years, applications of confluent jets for design of ventilation supply devices have been widely studied. Similarly, numerous studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. LÄS MER

3. 2. Air - for Health and Comfort, An Analysis of HVAC Systems' Performance in Theory and Practice

   Författare :Fredrik Engdahl; Avdelningen för Byggnadsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; indoor air quality; HVAC; infiltration; ventilation; VAV;

   Sammanfattning : One part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only.
