Control Systems for Heating, Ventilating and Air Conditioning,
Sixth Edition contains a comprehensive treatment of heating and air
conditioning system controls. This book was originally written to
provide fundamentals of HVAC control to practitioners who were
designing new control systems or maintaining existing control systems.
Emphasis on fundamental control system principles along with the
psychrometrics of air conditioning processes has remained a focus of
the new edition. While control system technology has changed
drastically over the years, the fundamentals of controlling heating
and air conditioning systems have changed only modestly.

Readers will find that fundamentals of existing control systems
remain in this book so that those who need to maintain or troubleshoot
systems that are twenty or thirty years old will be able to see what
practitioners did during that time frame. In addition the ubiquitous
application of digital control technology in very recent times is also
described. Note that the fundamental control principles once
implemented pneumatically are now being implemented in modern digital
computers - software now replaces hardware. Another change since the
last addition is a new emphasis on controlling minimum fresh air for
validation purposes. New techniques for doing this have been developed
in response to ASHRAE Standard 62, "Ventilation for Acceptable Indoor
Air Quality," and these methods are included.

Control Systems for Heating, Ventilating and Air Conditioning, Sixth
Edition is complete and covers both hardware control systems and
modern control technology. The material is presented without bias and
without prejudice toward particular hardware or software. Readers with
an engineering degree will be reminded of the psychometric processes
associated with heating and air conditioning as they learn of the
various controls schemes used in the variety of heating and air
conditioning system types they will encountered in the field.
Maintenance technicians will also find the book useful because it
describes various control hardware and control strategies that were
used in the past and are prevalent in most existing heating and air
conditioning systems.

Designers of new systems will find the fundamentals described in this
book to be a useful starting point, and they will also benefit from
descriptions of new digital technologies and energy management systems.
This technology is found in modern building HVAC system designs.
