Solar Thermal and Electric Desiccant Cooling System,Part 1 : System Development and Investigation | 2008 | English
Environmental degradation, depletingconventional energy resources, and explodingworld population are indeed serious issues.Development of clean energy resources togetherwith clean technologies for human comfort is awonderful hunian creativity.
In predicting flow rate of a cross-ventilatedbuilding, discharge coefficients obtained fromthe connected value of resistance coefficient ofopening based on the chamber method, and thewind pressure coefficients from a sealedbuilding are usually use
Some Effects of Ventilation on People: Perceptions, physiologicalResponses and Mental Performance | 2008 | English
This study explores the plausible mechanismlinking outdoor air supply rates and workperformance through the perceptual responsesand a target salivary biomarker.
Investigation of On-site Measurement of Air Flow Rate on Compact AirTerminal Devices | 2008 | English
On-site air flow measurements of domesticventilation systems with using funnel type airflow measurement instrument which isgenerally used in Japan, has been reported themeasurement difficulties due to the terminaldevices' installed location, the e
Energy efficient building means automaticallyextra attention to energy efficient ventilationand air tight building.
The decision makers in urban planning facevery often a dilemma whether to demolish orretrofit old buildings.
Displacement Ventilation System with Radiation Panel for Sickroom-Influence of Radiation Panel on Contaminant Concentration Profile - | 2008 | English
For the patient, the sickroom is a place for themedical treatment and is also the living spacewhere they spend almost all time in a day.Therefore, high indoor air quality and thermalcomfort are needed in the sickroom.We propose to use the displace
Measurement of total pressure, static pressure and wind velocity aroundcross-ventilated building | 2008 | English
Conventionally, the flow rate of a crossventilatedbuilding is predicted by using theorifice equation. When the opening is small,flow becomes like infiltration through cracks, itis useful.
Air-related problems in high-rise buildings:How can we cope with the problems due to stack effect? | 2008 | English
The construction of high-rise buildings beganseveral decades ago in North America, and nowhigh-rise buildings are common in East Asiaand the Middle East.
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
CFD Analysis of Airflow Characteristics inside Office Room with Hybrid Air Conditioning-System | 2008 | English
The hybrid air-conditioning system is consistsof natural ventilation and mechanicalair-conditioning system in this paper.
Performance of Whole-building Pressurization as Countermeasureagainst Stack Effect in High-rise Office Building | 2008 | English
This paper deals with pressurization usingHVAC systems on each floor as acountermeasure against stack effect generated inthe winter in high-rise office buildings that donot use revolving doors at the entrance.
Hybrid ventilation free-cooling simulation in Energy Plus. Application on ashopping center retrofitting, in Portugal. | 2008 | English
Buildings take a great share on the total energyconsumption and C02 emissions in Portugal.Poorly thought buildings pollute the urbanspace, and contribute to the increasing buildingssector energy demand.
