A Study of the Ventilation Performance for Automobile Indoor AirPollution Reduction | 2008 | English
In this study, we evaluated the ventilationperformance of an automobile interior with theaim of minimizing the influence of harmfulmaterials emitted from new cars.
Experimental Study on the Combined Effect of Outdoor Thermal-Environment and Ventilation Patterns on Indoor Thermal-EnvironmentControl for Summer | 2008 | English
If thermal insulation and solar control ofbuilding envelopes are appropriately made forindoor thermal environment control, then themoderate air current becomes relativelyeffective for thermal comfort especially inresidentional buildings in summer
Recently, dampness in buildings has beenindicated to be associated with occupants' healthdamages such as allergies. In particular mold inindoor air is considered to be a significant riskfactor of health.
Building performance can be expressed bydifferent indicators as primary energy use,environmental load andlor the indoorenvironmental quality and a building performancesimulation can provide the decision maker with aquantitative measure of the exte
Energy analysis of a personalized ventilation system in a cold climate: Influence of the supplied air temperature | 2008 | English
TII this study the influence of temperature of thesupplied air of a personalized ventilation systemon energy need has been investigated by meansof simulations with IDA-ICE software.
Study onAirflow around Building Roof for Design ofNatud Ventilation by Chmney- Part1 Distribution of wind pressure coefficient on a building roof - | 2008 | English
There are some ways to promote natural ventilation, but this research focuses on chimney which is traditional ventilation method used for industry or fireplace.
Tall buildings have traditionally been sealed andmechanical ventilated. In recent years advanceshave been made allowing the natural ventilationof tall buildings for a part of the year.
Numerical Simulation of Natural Ventilation Performance of SolarChimney with Built-in Phase Change Material | 2008 | English
This paper presents a study of solar chimneysusing a Phase Change Material (PCM)integrated into the heat absorber of the solarchimney.
Analysis for Wood Decay within Building Envelops Considering Moisture Production by Biochemical Reactions | 2008 | English
In this study, a durability assessment model forbuilding envelopes design based onhygrothesmal and wood rot decay analysis ispresented.
The concentration in the convection flows ofresuspended particles from the floor area wasexperimentally investigated under laboratoryconditions with different ventilation strategies.It was concluded that the number of smallparticles transported in
In building design the requirements for energyconsumption for ventilation, heating and coolingand the requirements for increasingly betterindoor climate are two opposing factors.This paper presents the schematic layout andsimulation results of an
The use of floor heating has been know sincemore than 3000 years from the Chinese Kang,the Korean Ondol, the Romans hypocaust to daysmodern water based systems embedded in thefloor construction.
Effect of technical solutions on non-heating and non-cooling temperatures and free cooling potential in office buildings | 2008 | English
In this paper we analyze by means ofbuilding simulation the effect of differentparameter combinations on the non-heating andnon-cooling temperatures of a typical airconditionedoffice building.
The Mechanical supply only (MSO) ventilationsystem has many advantages, such as good airdistribution, easy pre-heating of cold fresh airsupply and prevention of chemical aerosolsintake through wall cavity.
Adaptive Mesh Refinement Method Suitable for CFD Analysis of WindEnvironment around Buildings | 2008 | English
In order to generate effective grid for CFDanalysis of wind environment around buildings in urban area, we newly develop non-uniformtype adaptive mesh refinement method(NUAMR).
Advanced Distribution and Decentralized Supply : A Network Approach for Minimum Pressure Losses And Maximum Comfort | 2008 | English
The paper presents a new concept for a lowpressure drop supply system suited for theventilation of office spaces.
Domain decomposition technique is a methodfor CFD simulation, which can handle internalairflow of cross-ventilation of dwellingsseparately from extemal domain.
We are building a particle tracking systemfor the measurement of convective heat transfersand pollutants displacements in full scale rooms.To increase the depth of the zone of interest, thesystem is non stereoscopic and do not use laserlight.
It is often pointed out that when evaluating the energy-saving performance of equipment, it isimportant to take into consideration how theequipment under consideration is actually used.In evaluating heat transfer by contact duringfloor heating, it
