LoginThe heat sources in a room with upward air supply, can be ideally decomposed into some basic models.
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.
Forced air circulation in a storage room either with freezing/cooling or controlled atmosphere is usually turbulent because a high air change rate is generally required.
Health effects caused by aerosol air pollutants in the breathing air is a main target for occupational health investigations.
Condensation on the surfaces of diffuser and cold air dumping are the two major concerns in the application of cold air distribution brought about by the high temperature difference between supply air and room air.
The results of various numerical simulations of wind induced flows through large openings in a room are presented. The study is parametric on the sizes and relative positions of the openings and the wind direction.
CFD simulation of airflow and temperature field in a heated room has been described in the paper. The tracking of pollutant particle movement is also presented here.
In many new buildings the indoor air quality is affected by emissions of volatile materials.
Source/sink models of volatile organic compound (VOC) emissions from building materials are reviewed and a multi-zone ventilation model is developed to predict concentrations of contaminants in rooms.
A large number of the studies have indicated that chemical indoor air pollution has become an important environmental factor which influences the population's health.
For a large-scale building complex planned to be built in urban area, airflow around buildings and airflow inside a ventilated atrium of the building complex were estimated by CFO (Computational Fluid Dynamics) simulation, and wind and thermal env
In predicting the thermal environment of an indoor space affected seriously by the outdoor weather like an atrium using natural ventilation, it is essential to grasp the impact of the external outdoor weather precisely.
This paper presents a way of ventilating a large room so that the room can be divided into different zones by temporary vertical walls (canvas, plastic sheets etc) and with no physical ceiling.
In this paper the experiences carried out in a large church of Bologna equipped with a floor radiant panels heating plant are presented. High intensity air flows were measured not compatible with thermal comfort.
This paper presents an original air conditioning concept and design development elaborated for a large arena, designed to accommodate the indoor sporting events during the 2000 Olympic Games in Sydney, Australia.
In the large space, for example in large-dome, the space is often divided into some zones without partition walls for air conditioning.
The study of the flow in a room cooled by a fan-coil pointed out how the form of air flow and comfort could be influenced by the characteristics of the cold jet blowing out.
Usually, the performance of fan-coils is defined and measured in the laboratories only through thermal quantities. However, comfort conditions within a room depend also on the air flow pattern determined by the appliance.
This paper discusses the experimental study of direct delivery of cold air into a full scale environmental chamber using different diffusers, i.e. a multi-cone circular ceiling diffuser, a vortex diffuser and a nozzle type diffuser.
