After a brief treatment of the ideas and aspects that play a role in ventilation, gives a general outline of chosen investigation methods, with a concise review of apparatus and calculation models used. Presents a review of the ventilation investigations carried out by IMG-TNO during the last 10 years in factories, labs, hospitals, auction halls etc.
A short treatment of the concepts and aspects that play a role in ventilation is followed by a brief description of the investigation methods employed. Gives a concise survey of the equipment and mathematical models used. Reviews the ventilation research carried out by the IMG-TNO. Covers factories, laboratories, hospitals, auction halls and similar buildings.
TNO Research Institute for Environmental Hygiene have developed a mathematical model (based on an electrical analogue model) for deciding on the best ventilation system (natural v. mechanical) for a building while it is still atthe design stage. This model has been applied to an auction complex situated at Bleiwijk to deduce the best ventilation system for the building. Conclusions are that a natural ventilation system can be realized by placing ventilating devices exclusively in the roof.
