Analysis of fan-assisted natural ventilation in schools
(2005) 10th International Conference on Indoor Air Quality and Climate (Indoor Air 2005) p.1284-1288- Abstract
- During the last decade, a new design of schools with fan assisted natural ventilation has been introduced. Experience and knowledge of this type of ventilation system is therefore needed. The objective of the project is to study the technical and physical conditions required to ensure satisfactory ventilation. The whole project includes analyses of the air flows for different combinations of outdoor climates. In this paper the performance of the ventilation system in combination with the building is studied by computer calculations with the program PFS and full-scale measurements in school buildings. A model is built and can be used in the design phase when orders of magnitude are of interest. The significance of different design features... (More)

A model is built and can be used in the design phase when orders of magnitude are of interest. The significance of different design features can be studied making it possible to change or alter the final design. The breaking point when an auxiliary fan is needed in terms of air flow rate can be determined with the model. Comparison with measured air flows shows that the model gives results which are valid.
