Measurement of ventilation, air distribution and inter-zonal air flows in a 4-storey historic building using a passive tracer gas technique. | 1999 | English
Air temperature, air humidity and ventilation has been measured in a Swedish baroque castle. Results are presented for a measurement campaign comprising four periods under varying climatic conditions.
With a diameter of 320m, and a height of 50m the Millennium Dome is one of the World's largest enclosed spaces, probably the largest among those intended for public use.
This study is part of an investigation of the decontamination capabilities of indoor plants.Three internationally used species, Howea forsteriana Becc. (Kentia Palm), Dracaenaderemensis Eng.
The influence of an architectural design alternative (transoms) on indoor air environment in conventional kitchens in Taiwan. | 1999 | English
This study investigates indoor air environment via the flow fields, temperature fields and air contaminants (carbon monoxide) distributions in conventional residential kitchens, and looks for effective methods to solve those problems through natur
Individual air distribution control panel on partition panel at personal task area. | 1999 | English
A general trend in intelligent buildings is the decentralization of environmental controlsystems. Decentralized environmental control systems have many advantages over centralizedsystems.
Emissions from dust collected in air filters have been investigated using in situ and chambermeasurements.
Pressurisation tests of selected apartments as a base for analysis of natural ventilation in multifamily building. | 1999 | English
The paper presents a study on application of pressurisation tests of selected apartments as a base for analysis of natural ventilation in multi-family building. The analysis has been performed for 5-floor building constructed in late sixties.
Air cleaners are unitary devices that contain filtration media and fans. They are marketed for cleaning air in rooms.
The effect of loading dust type on the filtration efficiency of electrostatically-charged filters. | 1999 | English
Ventilation filters composed of electrostatically-charged fibers, also referred to as electret filters,are know to have the potential to decrease in filtration efficiency with use.
The design of natural ventilation systems - the configuration and sizing of system components - assumes one of two generic forms: the nasty form based on thermal comfort criteria or the nice form based on specified airflow rates.
Air recirculation in the new office and laboratory building of the Norwegian Institute for AirResearch was discovered and characterised from a leaking sulphur hexafluoride cylinderstored in the garage.
Particle concentrations in an air conditioned office building with normal and high efficiency filtration. | 1999 | English
Indoor and outdoor particle concentrations and ventilation rates were measured versus time ina large office building without tobacco smoking. Periodically, high efficiency filters replacedthe normal filters in air handling systems.
A measurement of the thermal performance and air distribution of indoor sports ground using swirling flow type natural ventilation system. | 1999 | English
This report describe the thermal performance and air distribution of a Kumamoto prefecturalindoor sports ground in Japan.
Airborne fungi in indoor air has the possibility to cause the air pollution problems of the fungally infection syndrome and the allergy syndrome, etc. in residence environments.
The cabin air filter performance is of prime importance for the air quality in vehicles. New clean filters were tested but also filters loaded with actual traffic contaminants. Both laboratory and field measurements were included in the study.
New thermodynamic energy "water potential" based on the chemical potential of a component of mixture gases is defined as the driving force of gaseous phase water flux.
Scale model experiments give possibilities for analyses of the design conceptions of ventilation especially of air distribution in large enclosures.
The ventilation engineer's plan at the design stage could be influenced by many factors. It may also be different from the requirements for the final users of the spaces.
In this paper, a zonal model used to predict the air movement, temperature distribution and airquality in a room is presented.
