LoginThe aim of this paper is to document an adapted methodology for the measurement of airflow rates provided by each unit, along with the inter-unit airflow rates and the global ventilation efficiency. A case study is presented.
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.
For that study, three different personalized ventilation (PV) systems are investigated : the desk-edge-based PV, PV using a movable panel (MP) and chair-based PV, they all are able to lower human exposure to ambient room pollutants.
This paper presents the discrepancies in applying the power-law model (PLM) for predicting indoor airflow distribution and the methodologies employed to improve this model.First, investigation was made to find an appropriate K value (flow coeffici
This paper investigates the ability of intermediate models such as zonal models to predict environmental conditions in a room.
Electronics densification is continuing at an unrelenting pace at the server, rack, and facility levels. With increasing facility density levels, airflow management has become a major challenge and concern.
Two high-performance prototype houses were built in Carbondale, Colorado, as part of the US Department of Energy’s Building America (BA) Program.
A new all-electric retail store located in Montreal, Canada, incorporates several design features to maximize the interactions between various building components.
This paper provides a method for verifying the accuracy of computer models that simulate the performance of the airhandling components of four types of heating, ventilating, and air-conditioning systems: the dual-fan VAV dual-duct system, the sing
Because of their ability to improve building air quality and their potential to reduce energy usage in some climates by allowing more conditioned air recirculation, use of gas contaminant filters in buildings is increasingly considered.
Volatile organic compounds (VOCs) are major gas-phase indoor air pollutants, and filtration is one of the promising methods to control indoor VOC concentration levels.
Experiments with room air distribution that is generated by a radial ceiling-mounted diffuser and a diffuser generating flow with swirl are compared with the air distribution obtained by mixing ventilation from a wall-mounted diffuser, vertical ve
The use of an underfloor plenum to deliver conditioned air directly into the occupied zone of a building is one of the key features that distinguish underfloor air distribution systems from conventional ducted overhead systems.
The flow of air through the porous media that is used as building insulation has the potential to recover energy normally lost through the building envelope via conduction.
Most epidemiological studies rely on outdoor concentrations for the estimation of exposures.
The bedroom is not an healthy place. Low air change rates are quite common. This paper describes the microclimate in a bedroom, focusing on the moisture balance, air flow patterns and house dust mite allergen.
Domestic air cleaner are expected as one of the effective technique for the removal of chemical substances.
For that study, experiments with task ambient conditioning systems (TAC) have been carried out, to investigate the effects on thermal comfort and productivity of workers. .
This paper reports the results of field measurements carried out in a classroom to evaluate the effect of the air quality and thermal environment on learning performances, with varying environmental conditions.
In this paper the review of literature dealing with exposure-response relationships between the concentration of pollutants and the perceived air quality is done.
A group of 24 tropically acclimatized subjects were tested to explore the thermal and air movement perception after 90 minutes of facial exposure to local air movement, at different temperature conditions.The aim of that paper is to identify when
