LoginIn raised-floor data centers, the distributed air leakage, which refers to airflow through the gaps between the floor panels, reduces the amount of cooling air available for direct cooling of computer equipment.
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.
Ever since the September 11, 2001, terrorist attacks and the subsequent anthrax incidents in the US, attempts have been being made to thwart further attacks and other forms of terrorism.Attacks involving chemical and/or biological agents (CBA) are
An experimental study and model analysis were performed to assess the effectiveness of commercially available in-room air cleaners in minimizing the impact of a hazardous aerosol released in a building.
The issue of assessing existing buildings in terms of their vulnerability to extreme man-made intentional threats has acquired great urgency in recent years.
Experiments with a fan-driven convector used for both heating and cooling are described in this paper. Only the cooling situation is considered.
Currently accepted best design practice for controlling airborne particulates in the hospital operating room relies on air flow type (laminar) and direction (down from ceiling). This is typically in the form of large arrays of laminar diffusers.
PIV data were used to evaluate a renormalization group (RNG) k-e turbulence model of airflow in a full-scale test room (5.5 × 3.7 × 2.4 m [18.0 × 12.1 × 7.9 ft]) using FLUENT software.
The effectiveness of an animal building’s ventilation system is usually characterized in terms of air exchange capacity (by measuring the air speed) and air distribution (by measuring the inlet air speed and airflow pattern).
In this paper, airflow in a slot-ventilated enclosure is numerically studied at Reynolds number 5024, which is based on inlet height and mean velocity at the inlet.
Draft and non-uniform fresh air distribution are common problems in winter ventilation, especially for large animal buildings. Thermal-based anemometers have difficulties in accurately measuring non-isothermal and low-speed indoor airflow.
This article presents a ventilation strategy that combines ceiling exhausts, bench exhausts, and ceiling radiant-cooling panels . It appears to provide very good thermal conditions and large energy savings for a typical laboratory.
The Carbon dioxide (CO2) and cubic-feet-per-minute (cfm) based methods are used to verify the amount of outdoor-air ventilation being delivered to building occupants , and to check that the minimum ventilation required by ANSI/Ashrae standard 62
This study presents a prediction of the space-time evolution of airborne pollutant dispersion following the accidental rupture of a containment enclosure (fume cupboard, glove box, pressurized gas duct etc.).
The authors have assessed a new method whose aim is to measure particles infiltrations in individual homes. That method consists in applying a recursive mass balance model to continuous indoor and outdoor concentration measurements .
An investigation was conducted on selected locations in air handling units (AHUs) to identify common mold species found on these locations and determine whether the operating condition of AHUs is related to that mold contamination.
For that study, a model has been developed in order to calculate indoor concentrations of PM 2.5.
Detection and diagnosis of multiple faults in VAV systems using principal component analysis (PCA) and joint angle analysis (JAA) are presented in that paper.
Parametric studies of facade designs for naturally ventilated residential buildings in Singapore were carried out in view to optimize facade designs for a better indoor thermal comfort and energy saving.
A questionnaire study has been carried out to investigate the prevalence of SBS (Sick Building Syndrome) in a multistory centrally air-conditioned Airport Authority of India building in New Dehli city.
This paper presents findings from an in-situ study on a group of minienvironments that focuses on the characterization and evaluation of their environemental performances in a clean room.
