LoginA fast and efficient computational model based on the method of proper orthogonal decomposition , POD, is developed to predict indoor airflows.
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 purpose of this paper is to review the existing material emission models, as well as to analyze the experimental methods.
This research studies the effects of source type and location on contaminant dispersion and exposure in a displacement ventilated room.
The air distribution in the room is mainly controlled by buoyancy forces from the heat sources, although the flow from the textile terminal can be characterized as a passive displacement flow with a downward direction in areas without thermal load
Designers of HVAC systems serving educational facilities face considerable acoustical challenges in applying equipment that complies with the acoustical levels specified in ANSI/ASA Standard S12.60-2002.
A hot and uncomfortable kitchen contributes to productivity loss, employee turnover, and eventually profit loss for the restaurant operator.
An initial study to develop a numerical tool using CFD methods for investigating the potential of disease transmission in commercial aircraft is completed.

This paper shows how a combined air-to-air heat and energy recovery system design problem can be formulated for HVAC cabinet units and solved for the least life-cycle cost system while still retaining a small time period payback.
This paper evaluates the operating cost savings and overall economics associated with these two different ventilation load reduction technologies : demand-controlled ventilation (DCV) and enthalpy exchangers.
Air-to-air energy recovery can be used to reduce ventilation loads for small commercial buildings. Enthalpy exchangers are one approach to energy recovery that is commonly employed.
Fan energy use in variable-air-volume (VAV) systems can be reduced by resetting the supply duct pressure. The standard way to reset duct pressure is by controlling the most open terminaldamper to a nearly open position.
The experimental study determined the degradation in performance of large axial fans caused by close inlet walls.
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
