Transfert de chaleur au travers de l'enceinte d'un système de traitement de l'air.

Heat transfer through casing of an air handling unit.

Résumé

The air handling unit (AHU) is widely used for heating, cooling, humidification, dehumidification and filtration of air for comfort and industrial purposes. The casing of AHU is one the main components which has a considerable effect on AHU performance. In this study, the thermal behaviour of AHU casing is investigated. The common structure of the casing is described and thermal classification of casing according to the 1886 EN standard is explained. A numerical study for a standard and a cold bridge free casing structure has been performed. Temperature distributions in the panel and profile are drawn for parallel and perpendicular connections. The effect of the cold bridge free structure on the temperature and heat flux of unit surface is also shown.
