Influence of natural convection on the thermal properties of insulating porous medium with air cavity. | 1999 | English
Thermal and ventilation characteristics in a room with underfloor air-conditioning system. | 1999 | English
It is the objective of the present paper to investigate indoor environmental characteristics ofan office building with an underfloor air conditioning system.
This article briefly describes a research program undertaken by the National Institutes of Health Office of Research Services to investigate ventilation performance of different laboratory configurations, and their affect on the hood.
Influence of air flow patterns in a room on evaporation and humidity distribution around a heated wet cylinder. | 1999 | English
Air flow patterns in rooms can roughly be classified as one of three types: Displacement flow, source flow and mixed flow. Displacement flow in its original meaning is only used in special applications like clean rooms.
The pattern of airflow influences the propagation of airborne pollutants, the thermalenvironment and general comfort conditions.
The main objective of this study was to determine the ventilation demand for a gymnasium inthe primary school based on verified metabolic rate.Norwegian guidelines recommend 6.0met as the activity level to be used when calculating the outdoor air
The Paper deals with numerical computations, carried out, in order to predict the effects of natural convection on the thermal performance of porous material.
Prediction of air flow in a single-sized naturally ventilated test room using artificial neural networks. | 1999 | English
The objective of this research is to investigate thermal comfort and air flow distribution insidea test room which is naturally ventilated. The test room is ventilated through adjustablelouvers.
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
The objectives of thisinvestigation were to examine the dynamic water vapour sorption offurnishing materials and to compare the experimental results withpredictions obtained from the Moisture Admittance Model.
Experimental and numerical investigation on temperature and air velocity distribution in a room equipped with split-system air conditioner. | 1999 | English
Split-system air conditioning is increasingly usedapplications, owing to its low cost and installationboth for residential and commercialease.
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.
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.
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.
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.
In this paper, analysis of the ventilation requirements of enclosed vehicular parking facilities is discussed. First, a compilation of existing U.S.
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.
