LoginThe first part of this paper deals with the performance of a ventilated ceiling system. Field measurements were made in a kitchen of a dietitics school in Kyoto practising mass cooking.
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.
The second part of the paper deals with the measurements of the indoor thermal environment and the ventilation performance of a commercial kitchen.Measurements were made with a tracer gas (SF6) which is non-toxic and odorless.A smoke machine (ROS
2 examples of extract systems are presented in this paper : the first one concerns dust removal in a public waste plant and the second smoke separation in a smoker/non-smoker zone with no visual impact (i.e.
The objective of this paper was to illustrate the potential of the CFD technique to compare the effectiveness of different general ventilation systems in reducing the workers' exposure to styrene vapour in a workroom. .
A validated CFD model was used to generate concentration distribution data for CO2, radon and moisture in a Hong Kong workshop with displacement ventilation.Contaminant concentration distribution depends on the contaminant source type and location
Emissions due to chicken farming should be minimised because they increase the greenhouse effect on the one hand and odours lead to annoyance.
This paper deals with the use of an Air Curtain Device in a typical HVAC application where there is a need to provide aerodynamic sealing between a comfortable human enclosure and a warmer neighbour space.Three different complementary experim
The Volatile Organic Compounds concentrations in indoor air tend to be higher than the level allowed by the standards or codes.
In general, there are 3 locations used for the fresh air supply in a standard cleanroom : under the ceiling of supply air plenum, at the return air shaft, and under the raised floor.
This report presents the status of airborne biocontamination measurements in France in residential and commercial buildings.
In 1998, an international research project entitled "Hybrid Ventilation in New and Retrofitted Office and Educational Buildings" was commenced under the auspices of the International Energy Agency.
In this paper, the normal ventilation system and the concept of all fresh air conditioning and ventilating system are presented.
In this paper, the authors are proposing a concept of a radiant ceiling panel HVAC system integrated with ice storage system to cope with the following requirements : load leveling, energy saving, cost saving and thermal comfort.
The aim of that study was to follow up the performance of ventilation in 2 buildings for people with respiratory illnesses.
For the protection of workers against the excessive radiation heat, local ventilation is used . But the distribution of locally supplied air has to be designed so as not to interfere with the production process.
The comparison of indoor temperatures measured in different Beijing buildings without air conditioners allowed those conclusions : the indoor temperature is different according to the floor at which a room is located , a high insulation of ex
In surgical operating theatres the concentration of contaminants to a minumum level is compulsory so an optimum design of air conditioning is required along with careful control of flow and temperature characteristics to achieve sterile condition
The aim for the design of the ventilation was to achieve the best possible air quality in the non-smoking zones and for the employees in a combined bar/restaurant. Air curtains are used to separate the zones.
In this paper measurement of local ventilation index and air exchange efficiency is presented. That work shows that with carefully design solutions, health risks for restaurant workers and bartenders can be considerably reduced.
This paper deals with an experiment made in a rest room located in the living quarter of a Norwegian oil platform in the North Sea.
