LoginThis paper gives an overview of sources of indoor particulate matter (PM) and its effects on occupants. Studies indicate that outdoor PM contributes to indoor PM, yet a large fractionof indoor PM is generated indoors.
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.
Velocity and turbulence intensity profiles of the airflow inside a section of a narrow body (737) aircraft cabin were measured using the particle image velocimetry (PIV) technique.In this paper the measurement technique is described and the result
An experimental study was conducted to estimate the leakage through air terminal connections to rigid duct and flexible duct.
Leakage data for ducted air terminal connections are reported. The leakage flow rate generally varied from 1% to 8% of the total approach flow rate.
Using a newly developed simulation model for electricpowered compression heat pumps, ventilation modules with an integrated exhaust air heat pump for supplying heat for passive solar houses are studied.
The purpose of continuous fan operation is to bring in fresh outdoor air to the conditioned space in order to maintain acceptable indoor air quality.
Many energy codes require that ductwork installed outside of the conditioned space be sealed. Prescriptive codes have no performance standard for what constitutes an acceptable level of duct sealing.
The airflow rate in heating and cooling equipment has major implications for the performance of the system.
Reducing the airflow and heat input rates of a furnace that is connected to a duct system in thermal contact with unconditioned spaces can significantly reduce thermal distribution efficiency.
This paper provides a summary of the methods and results of performance testing for a coupled Indoor/Outdoor Environmental Simulator (C-I/O-ES).
This investigation uses three subgrid-scale models of large eddy simulation (LES) to study airflows in and around buildings. They are the Smagorinsky model, a filtered dynamic subgrid-scale model, and a stimulated small-scale subgridscale model.
This paper presents the study of a local exhaust ventilation system with plain (unflanged) and flanged hoods.
Based on the algorithms of the stereoscopic particle image velocimetry (SPIV) we have developed, two digital cameras in an angular oriented configuration were used to simultaneously record two images of the same space of interest in a full-scale r
Recently indoor air quality (IAQ) became an important issue and as a result researchers have developed a large number of different air quality indicators.
Dedicated outdoor air systems (DOAS) integrated with ceiling radiant cooling panels as a parallel sensible cooling system are being considered as an alternative to conventional variable air volume (VAV) systems for commercial buildings because of
This paper describes a fault detection method developed for application to variable-air-volume (VAV) boxes.
A adaptive controller was devised and implemented within the ESP-r simulation program to support the conflation of CFD with dynamic whole building thermal simulation.
The impact of infiltration and ventilation flows on energy use in commercial buildings has received limited attention.
This paper presents the objectives and results of the initial stage of an ongoing research project on coupling of building energy simulation (BES), airflow network (AFN), and computational fluid dynamics (CFD) programs.
On the effects of decoupling airflow and heat balance in building simulation models | 2003 | English
Several thermal building simulators also allow coupled modeling of bulk air movements using airflow network models.However, solving the combined flow and thermal problem can be problematic, both in the context of traditional building simulators an
