LoginThe objectives of the present work are to use computational fluid dynamics (CFD) to studythe airflow pattern and to evaluate the effectiveness of the passive cooling design of theproposed Jurong General Hospital (JGH) using natural wind.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
Access to the publications is free of charge.
In 2003, the World Health Organization received reports of ‘Severe Acute Respiratory Syndrome (SARS)’ in various parts of the World. Until 13 June 2003, there were 1755 people affected by atypical pneumonia in Hong Kong.
Air supply diffusers used in air-conditioning systems can be classified as ceiling diffusers,side-wall diffusers, floor diffusers, jet nozzles and low velocity displacement diffusers.
The survey concerned three swimming pools using a similar type of basic water treatment, buthaving different structures and ventilation systems.
The paper presents part of the outcomes from the project set up by the Polish Committee forScientific Research and devoted to development of the recommended control strategies forDemand Controlled Ventilation (DCV) systems in Poland.
Various air cleaning technologies and products are commercially available to remove VOCsfrom indoor environment.
The impact of airflow interaction on inhaled air quality and transport of contaminants betweenoccupants was studied in regard to pollution from floor covering, human bioeffluents andexhaled air, with combinations of two personalized ventilation sy
The term air conditioning not only prescribes comfort temperature and the relative humidity,but also the quality of air inside the room. Indoor air quality (IAQ) has become a concomitantof air conditioning.
There are many schoolchildren who have a minor chemical sensitivity and cannot go toschool just because of the activities taken place such as arts & craft, waxing the floor or justopening the textbook.
This paper investigates the pollutant distribution patterns in a ‘negative pressure’ isolation room by means of objective measurement and CFD modelling.
Energy efficient operation of variable speed fans in Variable Air Volume (VAV) systems ishighly dependent on both the type of duct design as well as the type of control strategy thathas been implemented in association with the volume flow demand p
Air-conditioning and ventilation systems, which help to maintain the indoor environment ofbuildings, account for more than half of the energy consumed in them.
In this paper, the very recent laboratory research results on personalized air supply (PAS)from three universities are critically reviewed.
Problems of heat and mass transfer optimization in the plate cross-flow heat exchangers, usedin air conditioning systems for energy recovery from exhaust air, are discussed.
A thermal comfort designer is especially concerned with creating an environment to improvethe physical, mental and psychical health of human beings.
The quality of air in the indoor environment is dependent on the nature and source of indoorpollutants and the performance of the ventilation system. Increased dilution in a tropical contextimplies a high energy penalty.
The programme ‘Energy Audit’ has been worked out at the Energy Efficiency Centre of the Institute of Physical Energetics, LAS, and may be used for evaluation of heat losses from buildings and the economic efficiency of measures to be taken for the
A Personalised Ventilation system provides occupants with means of adjusting their individualthermal environment and of achieving good indoor air quality.
An assessment concept is being developed for iterative design of office buildings withintegrated energy and indoor comfort solutions.
The traditional ways of maintaining cleanliness, temperature and moisture level in anoperation theatre (OT) usually use larger HVAC system and keep both the heating andcooling functions operating at the same time.
