Performance of ventilator components for natural ventilation applications
Building and Environment, 2006Abstract This paper describes a series of laboratory experiments that investigated the airflow interactions that take place between components in louvered ventilators. The context of the work was to improve the design and performance of ventilators used in natural ventilation systems in buildings.

Natural Ventilation Potential of Urban Buildings
International Journal of Ventilation, 2005The design of a building should provide the flow paths needed for natural ventilation. Therefore, the decision to apply natural ventilation should be taken early in the building design process, when little information is available for airflow estimation.

A study of natural ventilation in a refuge floor
Building and Environment, 2007Under the Building Codes of Hong Kong Special Administration Region, the provision of refuge floors has been an indispensable element in high-rise building design since 1996. Wind-induced cross natural ventilation is an important design criterion of a refuge floor since it helps to prevent any smoke entering to become persistent state remained (logging)

On the aerodynamics of natural ventilators
Building and Environment, 1984Abstract The performance of natural ventilators subjected to the action of a free stream are experimentally investigated by using the method of Baturin. To analyse experimental data a mathematical model of the extraction characteristics is introduced.

Natural Ventilation of Parral Greenhouses
Biosystems Engineering, 2004Abstract A study was carried out at the Experimental Station Las Palmerillas of Cajamar to characterise the natural ventilation of the parral greenhouse. An 882 m2, five span, polyethylene film covered parral greenhouse was fitted with either a rolling or a flap ventilator attached to one side of each ridge and rolling ventilators in two 38 m ...

Soundproof Window - Natural Ventilation
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2021Expansion of brasilians cities worsen noise pollution in these places, forcing people to maintain their doors and windows closed. Domestic environment enclosing lead to necessity of air conditioning system, however the frequent use of the equipment may cause many health problems, such as respiratory difficulties and spread of diseases , not to mention

Natural and Mechanical Ventilation
1996It is a well-known fact that hot air rises and that its place is then taken up by colder air. This natural effect occurs because the density (mass/unit volume) of the rising column of hot air is less than that of the falling column of cold air. This process in its continuously operating mode is encountered in any naturally vented enclosure and also in ...

Natural Ventilation in a Model Room
Journal of Thermal Science and Engineering Applications, 2012Natural ventilation of a model room with water as the fluid medium is studied. It is insulated by air gaps on the four sides and at the top. A constant heat flux has been maintained on the bottom surface of the room. This room is surrounded by a large exterior tank containing water. There are three openings each on two opposing sides of the model room.

Review of natural ventilation models
International Journal of Ventilation, 2016ABSTRACTNatural ventilation (NV) is an important and efficient passive technique to reduce building cooling energy need and improve indoor air quality. NV design requires profound knowledge and accurate prediction of air flow and heat transfer in and around buildings that are highly dependent on varying external and internal conditions, as well as the ...
