This practical and comprehensive book on heating and air conditioning has been revised to include recent changes to system design, and covers many aspects in greater depth, whilst still retaining the character of previous editions. Building service engineers, architects and others involved in the construction industry should find this an accessible source of information on all aspects of the heating and air conditioning of buildings. This new edition includes: up-to-date information on the changes to the Building Regulations relating to energy conservation; revisions to practices arising from the enforced phasing out of CFE refrigerants; expansion and updating of the text on ventilation and air-conditioning systems; and the introduction of over 40 new illustrations.
