LoginThe 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.
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.
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.
Calculating the contamination concentrations in a space or the required ventilation for a spacehas been a difficult and confusing part in the application of the IAQ Procedure ofANSI/ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality
The simulation has been performed using the CFD package SWIFT. In the first phase, meanflow and thermal comfort parameters of the integral living room of the modern family househave been calculated.
The ventilated ceiling is a flexible solution for kitchen ventilation where the heat loads arerelatively low and aesthetics is a concern. The use of hoods is an ideal solution for locallyhandling contaminants produced in concentrated areas.
An advanced supply air filtration unit has been developed, and its performance was evaluatedin the laboratory. The filter consists of an electrically enhanced particle filter and an adsorbentfilter for gases.
Whilst Computational Fluid Dynamics (CFD) has been popularly applied in indoor air andventilation research, most Personalized Ventilation (PV) research is based on experiments.This study is an attempt to seek validation of PV experimental data wit
During the construction of Dhoby Ghaut Station on the MRT North-East line a 10-storeycommercial development was completed.
In time, ventilation ducts and accessories get dirty and this may lead to malfunction of ventilationequipment, fire hazard and especially a decrease in supply air quality. Repeated cleaningof the components can prevent these adverse effects.
