Since the publication of the first edition in 1992, the HVAC industry has gone through enormous changes. As simple digital systems have given way to more complex systems, demand for information on how these systems operate, how they are best applied and how they communicate with other building control systems has grown rapidly. Direct Digital Control for Building Systems, Second Edition is thoroughly updated and expanded to include coverage of the architecture of modern digital control systems, distributed intelligence networked systems, communication protocols, the technologies and issues concerning interoperability, the latest application strategies, and defensive techniques for designing and specifying control systems. Numerous illustrations throughout help keep the subject highly accessible, and hardware, software, and systems applications are described in the most universal terms possible. This thoroughly revised second edition also contains a full section on BACnet® standard and Echelon's LonWorks® technology; their meaning, applications, and future implications. An up-to-date appendix is provided. Insights on emerging technologies in intelligent control systems and what the future holds for this dynamic field is covered throughout.

Over two million commercial buildings in the U.S. are controlled by direct digital control (DDC) or like systems, and the trend is toward totally intelligent buildings by the end of this century. Even though DDC is quickly replacing traditional methods of controlling temperature, humidity, lighting, security, and life safety in commercial office buildings, guidance on the fundamentals, applications, and economics of DDC has been difficult to find. Applications-oriented and written from a practical point of view, Direct Digital Control for Building HVAC Systems is one of the first books to familiarize the reader with how to' specify, purchase, and support microprocessor-based building control systems. Even those with limited knowledge of digital technology will be enabled to implement DDC systems, thanks to down-to-earth descriptions of the purpose, benefits, and limitations, design, construction, operation, and cost of these systems. Especially valuable are the book's methods for interfacing digital control with existing HVAC systems. Mechanical engineers involved in the design of building control systems, mechanical estimators, facilities, plant, and building operations and maintenance personnel in both the public and private sector will all find this book a valuable resource.

In the eight years since the publication of the first edition of this book, there have been quantum changes in the automated temperature control (ATC) industry due to the widespread & growing use of direct digital control (DDC) systems. The fully updated second edition fully addresses these technology changes, from equipment characteristics & operation, to troubleshooting & maintenance, to training of operating & maintenance personnel. The full range of topics pertinent to the effective operation of all types of HVAC control systems currently in use today are explored, including equipment-to-control interactions, control system set-up & functions, local loop to building automation system interfaces, performance prediction & assessment, operational parameters, & maintenance & testing.

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 psychrometric 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.

There are two reasons why we have a new edition every four or five years. The first is that technology changes. Chapter 10, on computer-based con trols, has had to be almost completely rewritten. Fundamentals don't change, but the tools available to us do change. Evaluation and proper use of those tools makes it even more imperative that we understand fundamentals. Many of our control problems stem from the use of new devices as a solution to problems that are, in fact, control design errors. New gadgets, for example, Direct Digital Controls (DDC), will not solve basic problems and may even compound them. None-the-Iess, you will find an extensive discussion of DDC because I think it is the probable "future" in HVAC control. But it must be applied with a good understanding of fundamentals. The second reason is that I keep learning and need to pass on my new and improved understanding to my readers. Thus you will find a number of small but important revisions, a dissertation on control "modes," and a much more detailed discussion of how electronic control devices work. There are a few places where I have corrected what I now perceive to be errors. I apologize for these. I have been much encouraged by the acceptance of this book in the past, and I hope that this new edition will be helpful. Thank you for your support.
