Similar to supply air jets in mixing ventilation this paper describes a comprehensive flow model for displacement ventilation derived from the integrated…
A computational study had been carried out on hot and cold air interaction across the door of an urban transport vehicle. The studies show that within 20 s…
Simulations have been performed to investigate the performance of intelligent algorithms for control of indoor air quality through natural ventilation…
The trend towards improving building air-tightness to save energy has increased theincidence of poor indoor air quality and associated problems, such as…
Infiltration has traditionally been assumed to affect the energy load of a building by an amount equal to the product of the infiltration flow rate and the…
A wind tunnel study was carried out to investigate the airflow through courtyard and atrium building models. Ventilation strategies resulting from the use…
When designing a new, or retrofitting an existing building it is desirable to minimise theheatinglcooling load, total energy use and emissions from…
The inadequate dissipation of hurnidity fiom living spaces and bathrooms has become asignificant problem area in recent years. This can be attributed both…
The air distribution effects of floor mounted swirl diffusers are investigated and described inthis paper. Results are based on a case study of an office…
In this study, we have tested more than 80 silencers of different sizes (from O 250 to 1250), length, insulating thickness and with or without central pod.…
The design of natural, including passive, ventilation systems assumes one of two genericforms: the nasty design problem where the designer seeks to size…
A self administrated questionnaire was mailed to over 300 dwellings in blocks of flats usingthe wall exhaust. In almost all the dwellings there was a…
The air leakages can have a large impact on heating needs and thermal comfort in industrial buildings. This is sometimes poorly taken into account, both due…
The Dutch organization for applied scientific research TNO in Delft developed asystem of Controlled Natural Ventilation (CNV). It is produced by the…
Filters used for general ventilation are mass produced and tested by type at rated airflow rate in order to determine the evolution of the pressure drop and…
A systematic analysis of recently constructed dwellings in the Flemish Region has been undertaken within the SENVVIV-project (1995-1998). In total 200…
