Principles of Heating Ventilating and Air Conditioning

Principles of Heating, Ventilating, and Air Conditioning, a textbook based on the 2017 ASHRAE

Handbook—Fundamentals, should provide an attractive text for air-conditioning courses at engineering

colleges and technical institutes. The text has been developed to give broad and current coverage

of the heating, ventilation, and air-conditioning field when combined with the 2017 ASHRAE


The book should prove most suitable as a textbook and subsequent reference book for (a) undergraduate

engineering courses in the general field of HVAC, (b) similar courses at technical institutes,

(c) continuing education and refresher short courses for engineers, and (d) adult education courses

for nonengineers. It contains more material than can normally be covered in a one-semester course.

However, several different single-semester or shorter courses can be easily planned by merely eliminating

the chapters and/or parts that are least applicable to the objectives of the particular course.

This text will also readily aid in self-instruction of the 2017 ASHRAE Handbook—Fundamentals by

engineers wishing to develop their competence in the HVAC&R field.

Although numerous references are made to the other ASHRAE Handbook volumes, sufficient

material has been included from these to make this text complete enough for various courses in the

HVAC&R field. The material covered for various audiences in regular university courses, technical

institute courses, and short courses can and will vary greatly. This textbook needed to be complete

to satisfy all of these anticipated uses and needs. Toward this end, the following major sections are


Part I General Concepts, Chapters 1–10

Part II Air-Conditioning Systems, Chapters 11–16

Part III HVAC&R Equipment, Chapters 17–20

Although the 2017 ASHRAE Handbook—Fundamentals is published in an SI edition, which uses

international units, and an inch-pound (I-P) edition, this single version of Principles of Heating, Ventilating,

and Air Conditioning is designed to serve the I-P edition with some SI interspersed throughout.

There are several significant changes in this edition. Chapter 4 has new values for climatic design

information. Chapter 7 has been extensively revised with new design data. These changes make Principles

compatible with the 2017 ASHRAE Handbook—Fundamentals. In addition, the chapters on

system design and equipment have been significantly revised to reflect recent changes and concepts

in contemporary heating and air-conditioning system practices. Also, the Solutions Manual has been

extensively edited.

A particular point of confusion must be pointed out. Because this book was developed to be used

with the ASHRAE Handbook’s Fundamentals volume, a number of tables and figures have been

reproduced in the original form, complete with references to material elsewhere in Fundamentals

(not in this book). Thus, if the subheading in the table or figure indicates that it is a Fundamentals

table or figure, then all references to other locations, equations, tables, etc., refer to those in Fundamentals,

not in Principles.

Dr. Harry Sauer, Jr., one of the co-authors of this textbook, passed away in June 2008. Likewise,

William J. Coad was also a co-author of this textbook and passed away in August 2014. Both Dr.

Sauer and Mr. Coad made significant contributions to the book.
