Reseña del editor

In displacement ventilation systems, the principle of buoyancy is utilised to remove warm contaminated air from an occupied area. The main driving force is natural convection: instead of attempting to combat the forces of natural convection as in mechanical dilution ventilation, displacement systems supply and exhaust air in such a way as not to interfere with the convection currents set up by the heat sources in a space. Provided that pollution and heat sources are in close proximity, displacement ventilation can give better air quality than dilution ventilation, but good design is necessary to ensure that unacceptable vertical temperature gradients and cold draughts along the floor are avoided.
In this book the author, Hakon Skistad, draws on his long experience in the development, design and installation of displacement ventilation systems. The book deals with the principles of convective flow in rooms and of the air movement generated by different types of device that supply air at low velocity. It examines the implications of the interactions between these flows on the temperature and pollutant distributions in rooms, and provides guidance on comfort criteria, the selection of supply air terminal devices and system configuration. There are useful examples of design procedures for specific applications including a single cell office, a meeting room and an auditorium. The book is written for the practising engineer who is designing ventilation systems and for the student who needs to understand the underlying principles.
