Principles of Heating, Ventilating and Air Conditioning, 9th Edition

Principles of Heating, Ventilating, and Air Conditioning, Ninth Edition, is based on content from all four volumes of the ASHRAE Handbook, pulling heavily from the 2021 ASHRAE Handbook—Fundamentals. It contains the most current ASHRAE procedures and definitive yet easy-to-understand treatment of building HVAC systems, from basic principles through design and operation.

This book is suitable both as a textbook and as a reference book for undergraduate engineering courses in the field of heating, ventilating, and air-conditioning; for similar courses at technical and vocational schools; for continuing education and refresher short courses for engineers; and for adult education courses for professionals other than engineers, especially when combined with the ASHRAE Handbook.

Several significant changes have been made for this revised edition, including changes to chapter content and organization with the goal of ensuring the content is approachable and practical. For many chapters, a single example building is used to enhance consistency and further students’ understanding, and the removal of residential discussions and examples has given the book a more pointed focus on commercial calculations and applications.

Specific changes include the following, among many others:

In addition, several entire chapters have been removed from the print book but will be available online. The online materials include information on the following topics: Additional Psychrometric Charts
Air-Processing Equipment
Cogeneration and Heat Recovery Systems
Economic Analyses and Life-Cycle Costs
Heat Exchanger Equipment
Heating Equipment
Panel Heating and Cooling Systems
Radiant Times Series (RTS) Method
Refrigeration Equipment
Systems Design Problems

A paperback Solutions Manual with worked solutions to the problems at the end of each chapter is also available to instructors. To purchase the Solutions Manual, please email a request on university letterhead to educopies@ashrae.org
