air conditioning a practical introduction 3rd edition pdf

Air Conditioning: A practical introduction, third edition, is a textbool< for undergraduate courses in Building Services and Environmental Engineering, Mechanical Engineering, BTEC Continuing Education Diploma, Higher National Diploma and Certificate courses in Building Services Engineering, and will be of considerable help on National Certificate and Diploma programmes. Heating, ventilating and air conditioning is studied on undergraduate, CED, HND and HNC courses in Architecture, Building, Engineering, Building Management and Building Surveying and is part of all courses relevant to the design, construction and use of buildings.

The design of air conditioning systems involves considerable calculation work which is now mainly carried out with dedicated computer software; however, the engineering principles need to be fully comprehended in the first instance, as are the basic formulae and calculation techniques utilised. The reader is actively involved in the use of such data by the use of worked examples and copious exercises and design assignments.

Downloadable spreadsheets are used extensively throughout the book for assessing many cases of peak summertime temperature in buildings including The Shard at London Bridge, White Tower, London Olympic Velodrome, Solent University, Queens Building and housing. Workbook cases are provided for assessment of peak design cooling load and annual energy for locations around the world.

A downloadable file of climate data for many world locations demonstrates plant loads relative to London for quick assessment; these are mainly tropical and Middle East climates as these produce
multiples of the London load for the same building, for example The Shard, if it were transplanted elsewhere and among other similar towers. The Bourke Street case study is the result of an energy audit and discusses annual energy use. User data can easily be added to any workbook.

Downloadable workbooks are provided for air duct sizing, fan and system integration, air duct acoustic design, plus other assignment applications. All formulae used are explained with copious examples. The reader is encouraged to make full use of spreadsheets as a valuable aid to understanding without the need to be taught how to use dedicated software. The spreadsheets provided can be edited and easily enlarged or applied to other cases with the sample data provided or with the user’s own data.

Each chapter is introduced with lists of learning objectives and the key terms and concepts employed. Approximate samples of data from the Chartered Institution of Building Sen/ices Engineers (CIBSE) Guides are given for educational purposes in order to demonstrate how the reader can utilise the reference data when undertaking professional contracts. Sample data alone will be insufficient for anything other than the set exercises and only the most recent CIBSE Guide edition is to be used more widely.

The vitally important tasks of commissioning and maintaining systems are explained and provided with extensive checklists so the reader understands that design calculation alone will not make a mechanical and electrical system function or keep running by itself; pressing the on switch is not enough. Testing air leakage IS explained and this is applied to measure building air tightness in the CIBSE PROBE reports mentioned. Mass cooling has been used widely in recent years to reduce plant cooling load and these opportunities are discussed. Standard topics of system types, psychrometrics, load calculation, air duct and pipe sizing, fan and system interaction, control methodology and thermal storage are extensively explained with many worked examples and assignments.
