LoginThe experimental study determined the degradation in performance of large axial fans caused by close inlet walls.
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.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
The air performance effects expected due to inlet velocity distortion for axial fans is predicted based on basic airfoil data. This expectation is compared with the test data gathered in RP-1010.
This paper summarizes the results of field measurements that were conducted in four operating diesel locomotive shops. The physical geometry and ventilation system design are documentedfor each shop, and their usage is described.
This paper compares CFD models and field-measured data from four large enclosed locomotive facilities. For each facility, CFD models were built using two computational fluid dynamics programs.
A research project is being conducted at the National Research Council of Canada (NRC) to evaluate the effectiveness of current emergency ventilation strategies to control smoke spread in the event of a fire in two road tunnels.
This paper presents a comprehensive discussion about past, present and future research focused on air curtain performance optimization. The past reserach mostly relies on simplified analytical solutions for jets.
Current models and test methods for determining filter efficiency ignore filter bypass, the air that circumvents filter media because of gaps around the filter or filter housing.
Fifteen air cleaners, representing different technologies and types of devices, were tested with a mixture of 16 representative VOCs (17 VOCs in tests for products associated with ozone generation) in a full-scale stainless steel chamber by using
When ASHRAE Standard 52.2-1999 was written, Standard Project Committee 52.2 recognized that the first dust loading step, also called the conditioning step, was not fully adequate for revealing the drop in efficiency that electret filters undergo d
The comparaison within the same Scandinavian airline company of the prevalence of health symptoms and perception of cabin air quality (CAQ) among commercial cabin crew with office workers was the main aim of this study.
The supply CO2 based demand controlled ventilation (S-CO2-DCV) proposed in this paper is one of the strategies that could reduce energy use by reducing the unecessary overventilation of buildings.
This study is an attempt to characterize the size relationships of bacteria and particles that mainly are of human origin.
Concentrations of airborne culturable bacteria in 100 large US buildings from BASE study | | English
This paper is a presentation of statistics made by the US environmental protection agency BASE. A standardized protocol was used to measure bioaerosols whose air samples were collected in 100 large US office buildings in 1994-1998.
The authors of this paper have summarized and interpreted portions of the data collected for the Building Assessment Survey and Evaluation BASE study.
A quantitative relationship between a room’s pressurization ratio and its leakage airflows has been established in recent ASHRAE research.
This paper provides a method for verifying the accuracy of computer models that simulate the performance of the airhandling components of three types of heating, ventilating, and air-conditioning systems: the constant volume terminal reheat system
This paper considers the effect of air properties on ammonia levels in the cages and main room space of an animal research facility containing mouse static micro-isolators.
Evaluation of the ventilation effect and indoor air quality in ventilated rooms is very important for ventilation system design.
To save energy and comply with the IAQ procedure in ASHRAE Standard 62-1999 or to add protection to occupants and contents in a building, more building owners and facility managers are using gas-phase filtration (GPAFE) in their buildings.
This paper presents the effects of façade design on crossventilation for Taiwanese elementary schools that are typically naturally ventilated. A prototype classroom that serves 30 students with divided upper and lower windows was used.
