LoginA subjective study is reported in that paper concerning a field environmental chamber (FEC) equipped with a displacement ventilation system (DV).
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
In order to study the impact of the outdoor air on the indoor environment, suspended particulate matter were simultaneously sampled indoors and outdoors of a typical residential house in the Al-suwayq area.
For that study CFD models have been developed to simulate the transport of infectious droplets and bioaerosols in a hospital ward. Those models will help for the design and control of a local exhaust ventilation (LEV) system.
The modified T-method can be applied to the prediction of the flow distribution in multi-fan duct systems.
For that study, numerical simulations along with full-scale laboratory experiments have been carried out to investigate the influence of the porous screens on the temperature fields, flow fields and ventilation rates within the kitchen.The air ex
A new concept, called Integrated Accessibility of Contaminant Source (IACS), has been proposed to consider simultaneously the positioning of a contaminant source, the distribution of occupants along with the overall airflow pattern.
This paper studies particle diffusion of a wide range of particle sizes compared with the diffusion of passive contaminant under the same conditions.
The evaluation of a quantitative method for culturing particles on HVAC filters is the aim of this research.
Do multiple solutions of natural ventilation exist in complex buildings and what are the physical mechanisms that can lead to a such existence ?
Stacks can enhance the natural ventilation of buildings. They can drive ventilation in floors where there is little heat load.
The most recent initiative taken by the Hong Kong SAR government to improve IAQ in various facilities is fan IAQ certification scheme for offices and public places.
In a naturally ventilated flat, indoor and outdoor characteristics of particulate matter (PM) were studied .In that aim PM concentrations were measured in winter and summer. The results and their analysis are presented.
A typical office building in Honk Kong was used to study the effect of air supply temperature on the performance of displacement ventilation. That system appears to provide acceptable thermal comfort at certain air supply temperatures.
The aim of that study was to establish a methodology to quantify the ozone emission rate from electronic air cleaners, along with the ozone decay parameter. For that experiment 3 different portable ionisation-type air cleaners were used .
One strategy to secure the release of hostages held by terrorists, is to release an anaesthetic agent through the ventilation system. But it is not so easy to apply.
Ventilation rates and main parameters related to IAQ have been tested in some office buildings and residential houses whom occupants complained about the bad indoor air quality.
Thanks to a right air filtration strategy a good IAQ does not have to cost more. Advances in air filtration allow the development of systems that provide superior IAQ with a reduction of energy costs.
In USA, after the 2001 bioterrorist attack, filtration efficiencies have been evaluated at three US. Postal Service (USPS) facilities.
The evaluation of the effectiveness of a portable high efficiency particulate air (HEPA)-filtration unit to reduce MRSA environmental surface contamination within a clinical setting, was the aim of this paper.
The airflow interactions that take place between components in louvered ventilators have been investigated in a series of laboratory experiments and described in this paper.
