LoginThat study whose aim was to determine mixing coefficients for a two-zone model of displacement ventilation was carried out in 43m2 model room equipped with various heat sources to create realistic convection air flows.
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.
This paper presents first an overview on the current state of Demand Control Ventilation (DCV) technology for commercial buildings.Then it deals with the performance of existing systems - what is working well - with possible alternatives for the
Laboratory measurements of a ventilated ceiling in a mock-up kitchen are presented in that paper.
This study aims at developing a new ventilated window consisting in a triple glazing unit with dual airflow paths. The performance testing of such a system has been made possible thanks to CFD simulations.
A method to develop HVAC equipment models with BMS data using RNN - recurrent neural networks - is proposed in this paper.
This report discusses the importance of airflow passing from a house into its pitch roof carrying heat and moisture. . For the prediction of the indoor airflow patterns, detailed tracer gas measurements and simulation tools (CFD) have been used.
Identifying optimal conditions for both human health and work productivity in office rooms was the aim of this study based on published reports and other information concerning air-flow and temperature in Swedish office buildings.
This paper is a literature review of Indoor Air Quality provided by air conditioning systems with underfloor air distribution. Practically all the studies indicate UFAD systems really promote an improvement of IAQ.
The chemical nature of the odorous compounds released from used ventilation filters has been investigated in that paper by simultaneous ordor evaluation and chemical analysis of air before and after the filters.
The effect of filtration on secondary organic aerosols (SOA) resulting from reactions between indoor limonene and ozone under a recirculation scenario, is examined in that paper.
This study experienced the capability of soil to purify indoor air pollutants. The efficiency of reducing the concentration of VOCs was examined for the soil where plants could be buried. Experiments were performed.
The purpose of this study was to investigate the sensory emission load from an alternative ventiltion bag filter with activated charcoal lining and to compare it with a used bag filter.
Activated carbon filters have been installed within the air handling unit of an HVAC system feeding 100% fresh air to an office building.
The tests were made in a empty experimental surgical room for pre clinical animal research. The measurements were made with 3 filters efficiency : 65 %, 85 % and HEPA filter, according to ASHRAE conditions.
For the removal of volatile organic compounds (VOCs), zeolites can be used. This paper deals with the removal performance of toluene in gas phase.
For that study 60 subjects in groups of six, were exposed for five hours to two levels of air pollution, four levels of absolute air humidity, and three air temperatures .
The aim of that study was to evaluate the environment's thermal conditions so as to indentify the comfort and localized discomfort conditions in office buildings with underfloor air supply systems.Parameters of thermal comfort and of system operat
The first part of this paper is a presentation of a simple method using commercial CFD software to obtain the solution multiplicity characteristics of laminar and turbulent indoor airflows.A two-zone naturally ventilated building with four openin
In the second part of this paper a simple two-way simulation method is implemented using CFD software to obtain the multiplicity behavior of laminar and turbulent indoor airflows in two-zone naturally ventilated buildings.
That study about the development of new convection correlations for rooms with cooled ceiling (CC) panels has two main objectives : - to develop convection correlations for the CC surfaces in rooms with only natural ventilation.
