Experimental and numerical investigation on temperature and air velocity distribution in a room equipped with split-system air conditioner. | 1999 | English
Surveys on repressurization-induced backdrafting and spillage were conducted in threedifferent areas of the United States using a common protocol, primarily to assess thecorrespondence between short-term tests and one week of continuous monitoring
Evaluation of temperature distributions and airflow patterns with three air diffusing systems in heating period. | 1999 | English
This study is to investigate the characteristics of indoor air temperature distributions and airflow patterns with three air diffusing systems in heating period and to find the methods which can predict those indoor environmental conditions effect
Comparison of mechanical and natural ventilation using long-term evaluation model for indoor air quality, thermal environment, and energy consumption. | 1999 | English
There are often tradeoffs among improving IAQ (Indoor Air Quality), maintaining thethermal comfort, and reducing energy consumption for HVAC (Heating, Ventilating, and Air-Conditioning) systems.
The air quality in a subway-train was studied to suggest optimal design criteria and operationconditions based on the ventilation demand by passengers. The C02 emitted from thepassengers was the tracer for this study.
Prediction of the indoor air quality trend in a dwelling in the Mediterranean climate. | 1999 | English
The purpose of this study was to evaluate the indoor air quality parameters in a residentialdwelling using information from the field.
Evaluation of the effects of ventilation systems on temperature, humidity, air quality and energy consumption in multiple dwellings. | 1999 | English
Recently well-insulated and well-airtightened houses are increasing in Japan. Those houses havesome problems of air quality because of formaldehyde from construction materials. Ventilationsystems have possibility to solve these problems.
A study on the characteristics of indoor environment and comfort in office building with underfloor air-conditioning (UFAC) system. | 1999 | English
During the last decade, an increasing interest in Underfloor Air-Conditioning (UFAC) systems has emerged. This is due mainly to an increased demand from employees for a greater control over their working environment.
Within an International Energy Agency (IEA) project (Annex 27) experts from 8 countries(Canada, France, Italy, Japan, The Netherlands, Sweden, UK, and USA) have developed toolsfor evaluating domestic ventilation systems during the heating season.
Application of statistical experimental design for parametric simulation studies in building physics, with an emphasis on indoor air. | 1999 | English
Parametric studies have often been used for sensitivity analyses in the field of the pharmaceuticaland agricultural sector.
Performance evaluation of a displacement ventilation system for improving indoor air quality: a numerical study. | 1999 | English
To evaluate the performance of a ventilation system, the local mean age of air has usually been used to estimate how efficiently fresh air is diffused to a desired location.
In this paper, analysis of the ventilation requirements of enclosed vehicular parking facilities is discussed. First, a compilation of existing U.S.
Comparison of modelled and measured tracer gas concentrations in a multizone building. | 1999 | English
Few detailed comparisons of modeled ad measured pollutant concentrations in multizonebuildings have been published.
The influence of air supply and exhaust locations on ventilation efficiency and contaminant exposures in rooms. | 1999 | English
An efficient ventilation system is characterised by a well-organised and turbulence-controlled airstream that rapidly corrects disturbances in air quality and thermal comfort in the ventilated space.Air supply and exhaust conditions are investigat
Based on concerns about indoor air quality and trends towards tighter envelope construction,there has been increasing interest in mechanical ventilation of residential buildings in the UnitedStates.
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.
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.
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
