LoginThis paper gives an outline of the work that has been carried out in developing a positive ventilation chiller.
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 Equitable Building, which opened on 1January1948, in Portland, Oregon, was the first of a new architectural form. Technically and aesthetically it was radically different from any previous structure.
The acoustics and ventilation method allows the designer to explore natural ventilation and acoustics issues at an early design stage.
Technology Programme INVENT took place in Finland from 1991 to 1996. In this programme over 100 R&D projects were completed and over 20 Million US dollars used to promote industrial ventilation equipment, systems and services.
Although the REEXS-principle Reinforced Exhaust System) has been the object of numerous investigations, who found substantial improvements compared to ordinary local exhaust ventilation hoods, it is far from being generally accepted and used.
The assessment of human exposure to airborne contaminant is an important issue in building design. The physiological significance of such exposure and technical means to minimise such risks have long been known in literatures.
Recently, the need to control environmental tobacco smoke {ETS) in restaurants and bars has increased.
Nicotine concentration in air has been measured in several restaurants by different measuring techniques.
The ventilation efficiency in a displacement ventilated room with non-buoyant pollutant sources was evaluated under laboratory conditions.
Zonal models are often used in analytical calculation of temperature, concentration or humidity conditions in ventilated spaces. The space is divided in two or several zones ( 1 ).
A great deal of the literature on general ventilation expresses the adequacy of the volumetric flow rate of air in terms of the number of room air changes per hour.
A pulse pressurization technique to measure the airtightness of the building envelope is developed. The governing equations are introduced and the procedure for deriving airtightness parameters from the pressure decay curve is shown.
In North America, there is an ongoing effort to repair the effects of corrosion in large boilers and pressure vessels. In recent years this work has been done from scaffolds erected in the boiler or vessel.
Many hazardous chemicals are used in research laboratories. Fume hood is the most efficient and common single equipment used in prevention of chemical exposure of laboratory workers.
The reintroduction of toxic gases emitted from roof stacks can significantly affect the quality of the air inside a building.
