Measurement of ventilation, air distribution and inter-zonal air flows in a 4-storey historic building using a passive tracer gas technique. | 1999 | English
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.
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
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.
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 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.
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.
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.
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.
A field experiment on indoor consistency distribution of combustion gas by ventilation performance of range hood. | 1999 | English
In apartments of Korea, exhaust-only hood system is commonly installed for kitchen ventilation.
The role of indoor plants as a source of microorganisms was studied in six office rooms.Concentrations of microorganisms (both fungi and actinomycetes) were determined fromindoor air and settled dust before the plants were placed in the office roo
Many HVAC systems built in the time between 1960 and 1980 have now reached the end oftheir lifetime and require retrofitting.
Influence of ventilation systems on aerosol and vapour concentration in the kitchen. | 1999 | English
During the experiments and under the experimental conditions, displacement ventilation with air outlets close to floor level were found to produce the lowest concentrations of hazardous substances and aerosols in the working areas of kitchen appli
In this paper, a zonal model used to predict the air movement, temperature distribution and airquality in a room is presented.
Computational analysis of indoor air and temperature distribution in an office space. | 1999 | English
There is a growing demand for buildings to have a high indoor air quality environment. Twoof the main elements that contribute to this quality are temperature and air distribution withinthe occupied space.
An efficient numerical method for solving the Reynolds-Averaged Navier-Stokes (RANS)equations with turbulence models for complex geometry and high Reynolds number flows isused to perform a highly-resolved computation of the turbulent flow in a str
