The effectiveness of ventilation related to the two primary tasks of ventilation, (I) the supply of fresh air, and (ii) removal of contaminants, is…
The aim of this research is to apply dynamic Large Eddy Simulation (LES) to predicting the complex turbulent flow field in an air-conditioned room. LES is a…
Three very different task/ambient conditioning (TAC) systems were investigated in a climate chamber. Two desk-mounted TACS, the “Personal…
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…
In this paper, analysis of the ventilation requirements of enclosed vehicular parking facilities is discussed. First, a compilation of existing U.S. and…
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…
The objectives of thisinvestigation were to examine the dynamic water vapour sorption offurnishing materials and to compare the experimental results…
The influence of natural convection on the thermal properties of insulating porous medium with air cavity is studied. Here, the combined effect of air…
Results are presented from a study of the performance of fuzzy, rule-based algorithms for thecontrol of indoor air quality through combined control of…
Recent years have brought the popularity of methods in which neutral networks are applied. They seem of particular importance while dealing with diagnosing…
Temperature and relative humidity have been measured in a BRE test house to investigate the vapour content in the void beneath the timber floor. The void…
An efficient ventilation system is characterised by a well-organised and turbulence-controlled airstream that rapidly corrects disturbances in air quality…
The air quality in a subway-train was studied to suggest optimal design criteria and operationconditions based on the ventilation demand by passengers. The…
There are often tradeoffs among improving IAQ (Indoor Air Quality), maintaining thethermal comfort, and reducing energy consumption for HVAC (Heating,…
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…
Particle deposition from turbulent duct flow is modelled and related to particle penetration of a ventilation system for a commercial office building. Three…
A secondary analysis of the Dutch prevalence study by Zweers et al shows that office buildingswithout artificial cooling and with operable windows have a…
With increasing demand for acceptable indoor environment it is necessary, already in theconstruction phase, to estimate what effect different environmental…
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…
Within an International Energy Agency (IEA) project (Annex 27) experts from 8 countries(Canada, France, Italy, Japan, The Netherlands, Sweden, UK, and USA)…
