Safety
Safety is stressed as priority #1 throughout this
book. Safety notes relating to specific lessons, tech-
niques, and procedures appear throughout the chapters.
Always read and understand these safety notes and any
other safety training provided by your instructor before
attempting any hands-on work.
Content Sequence to Provide
Optimal Instruction
Starting with domestic refrigeration, this book
will guide you from basic understanding up through
introducing increasingly complex systems. A solid
foundation in the fundamental understanding of how
each HVACR component works will permit you to com-
prehend how a complex commercial system functions.
As you look at Figure B, which lists the major content
sections of the book, visualize the career pyramid
superimposed over the breakout of topics. You should
be able to see how a strong understanding of the foun-
dational information is applied as you advance to more
complex systems.
This highly illustrated book introduces the under-
lying science on which every refrigeration system is
based. Essential tools and techniques for working with
refrigeration systems will offer many hands-on learn-
ing opportunities. These lessons will be followed by
coverage of the properties of refrigerants. A thorough
introduction to electrical and electronic theory, sys-
tems, and components concludes the coverage of foun-
dational knowledge.
With a sound background in these fundamental
topics, you will begin work on domestic refrigeration
systems and then progress into air-conditioning sys-
tems and heating systems. Ultimately, you will use
the knowledge gained to understand more complex
