This pocket book is packed full of all the reference material that building services students, mid-career engineers and those involved with operating and managing building services are likely to need. It is assumed that the reader has some knowledge of the fundamental physical processes involved in mechanical services.This book guides the reader in their choice of system by giving the principal characteristics of different types of HVAC system. It is also written to take the inexperienced engineer along the difficult path of producing initial theoretical designs and converting them into full working designs. It takes into account the need to rationalise certain aspects of detail design to facilitate modular construction, prefabrication, cleaning, maintenance and save time.
