LoginThis paper examines the performance of five different air terminal devices for personalized ventilation in relation to the quality of air inhaled by a breathing thermal manikin in a climate chamber.
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.
A personalized ventilation system located underneath the front edge of a desk was tested regarding to its ventilation efficiency using a heated mannequin and tracer gas. The air change effectiveness ranged from 1.4 to 2.7.
Performance on a long-term period of time of an HVAC installation to ensure thermal comfort conditions can be evaluated by estimating the number of hours when the thermal condiitons are outside a given range.
A thermal manikin with a simulated lung was placed in an air-conditioned office with fresh air supplied in close proximity to the facial area at flow rates from 0.1 to 2 l/s.
Ventilation and indoor air characteristics were measured in 63 apartments for elderly people in Finland and residents were inquired about indoor climate. Results are shown and analysed.
This paper discusses architectural design of buildings for a good indoor air quality, material selection, building design process, relationships between indoor and outdoor air quality.
This paper presents a complete overview of energy and indoor air quality issues related to ventilation.
The study in 5 European countries has shown that indoor air quality was noted depending on the country first and on the perceived thermal comfort.
Numerical modelling of convective air movements inside a heated room was built, using a coupling of a zonal model and integral analysis.
This paper deals with the CFD (Computational Fluid Dynamics) method used for the analysis of the micro-climate surrounding the human body.
At first, this paper deals with the history of indoor environment and ventilation , with the evidence that a good IAQ is essential for public health.
Concerning thermal comfort (number one complaint in most offices), the range of occupants needs is very wide.
This work deals with the characterization of the thermal performance of a LHS (Local Heating System) tested on 18 persons (9 males and 9 females) working in a real free-running office with mean room temperatures varying from 16C to 18C.
For workers sharing the same office, there is normally a need for slightly different temperatures to fit their own optimal thermal comfort.
30 human subjects participated in a 3 h 45 min.
This paper deals with experiments made to test the performance of a personalised ventilation system (PVS).
Advances in infection control practices include improved operating room environment (airflow velocity, turbulence level, temperature, and relative humidity). Operating theatres are complex spaces.
This work concerns turbulence levels in a practical operating theatre of a 1200 beds Egyptian modern teaching hospital. The turbulence characteristics were represented by a modified k - epsilon model.
This paper deals with the development of 2 approaches for the modelling of the transport of gaseous pollutant with CFD code Fluent.
This paper describes the precautions that have to be taken in design and installation of ventilation systems in order to reduce their noise. They concern fans, ducts and ductwork, air inlet and outlet, air diffusers, air handling unit.
