Moisture movement and extractor fans: Experimental study

Abstract

This paper describes an experimental study of moisture migration in a small dwelling. Experiments were carried out to measure the migration of moisture from the kitchen and bathroom to the rest of the house. Extractor fans and a cooker hood were operated to reduce the migration, and their effectiveness was measured. The tracer gas step-up method was also used to measure the air movement. The transfer index was used to characterise the migration. The results show the relative effectiveness of the fans running at various speeds. They also show how much moisture and tracer gas migrates into each room. © 1993, Sage Publications. All rights reserved.
