Synopsis

Using a minimum of mathematics, this book explores the fundamental concepts of air conditioning and their application to systems—explaining all concepts in a clear, practical manner, and focusing on problems and examples typically encountered on the job. This book contains the most recent and industry-wide accepted information on load calculations, design data, equipment information, and use of the Internet. Specific chapter topics cover the scope and uses of air conditioning; physical principles; heating loads; furnaces and boilers; hydronic piping systems and terminal units; cooling load calculations; psychrometrics; fluid flow in piping and ducts; piping, valves, ducts, and insulation; fans and air distribution devices; centrifugal pumps, expansion tanks, and venting; air conditioning systems and equipment; refrigeration systems and equipment; automatic controls; energy utilization and conservation; instrumentation, testing, and balancing; and planning and designing the HVAC system; and solar heating and cooling systems. For consulting engineers, mechanical contractors, HVAC engineers, designers, project managers, and facilities managers.

From the Back Cover

A classic in its field, Air Conditioning Principles and Systems continues to fill the need for a text book on air conditioning systems that combines design principles with real-world applications. Readers will gain insight into the design, operation, and troubleshooting of new and existing air conditioning systems. Moreover, this edition has been updated to reflect recent developments and issues in the industry, including the increasing use of the Internet in the field.

Key features of this edition:

• New weather data for outside temperature analysis and system design.
• Expanded information on environmental problems to help readers stay current on issues and regulations.
• New information about asbestos, including answers about mitigation of harmful effects.
• Further exploration on scroll compression and how it works in real-world applications.

This fourth edition of Air Conditioning Principles and Systems has been significantly revised. Reflecting recent developments and concerns in the industry, substantial material has been added on indoor air quality, air pollution from combustion, and the new environmental requirements on refrigerants. Consistent with the overall philosophy of this text, the practical approach to these important issues will enable the reader to effectively address them in the workplace.

Use of the Internet for air conditioning work is a major component of this fourth edition. Many Websites of equipment manufacturers are listed. Problems are assigned that make use of these Web sites for equipment performance, selection, and specifications, and to ask and receive answers to technical questions. Web sites of HVAC design software providers are also listed. These offer heating and cooling load calculations, duct and pipe sizing, psychrometrics, and energy analysis. Problems are also assigned in these areas. Use of design software often entails a fee and restrictions, of course. The Web sites and software listed in the text are only a small sample of those available, and are not necessarily the only useful ones. A search will discover many more.

In addition to incorporating new material, many chapters have been considerably revised or amplified to enhance the learning process.

This book is a fundamental text in heating, ventilation, and air conditioning (HVAC). It fills the need for a text that presents the fundamental principles and systems in a manner that is technically accurate, yet of practical use in the working world. Today's reality, which mandates time and cost effectiveness in HVAC work, dictates this practical approach. Students in air conditioning and refrigeration courses in college and technical institute programs, and consulting engineers, contractors, operating engineers, and service technicians will find this text useful in their studies or as a reference.

The book is designed for a two-semester course. Supplemental work may be assigned if the instructor wishes to expand on the suggested projects.

The text begins by developing the fundamental principles of air conditioning, followed by a description of equipment and systems. The text emphasizes the application of theory to both designing new systems and troubleshooting existing ones. This approach is enhanced by many illustrative examples and problems dealing with real situations.

An underlying theme throughout the book is energy utilization and conservation. Energy codes and standards are described, and each topic is examined from an energy conservation viewpoint, an approach that is essential for all future work in the air conditioning field. A chapter is devoted to solar heating and cooling.

Following an overview of the scope of air conditioning, the text reviews physical principles. Heating and cooling load calculations are explained in a thorough yet understandable manner. The latest methods (now required by most states) are used. The newly revised design weather data is included. Load calculation forms are furnished to aid the student. The subject of psychrometrics is presented in considerable detail, recognizing that it is at the heart of understanding air conditioning processes.

Air conditioning and refrigeration equipment and systems are covered thoroughly. Equipment construction and selection are described. Included in the discussion are reheat, dual duct, multizone, hydronic, and variable air volume systems. The presentation of refrigeration includes an explanation of absorption systems, heat pumps, and the scroll compress.

Instrumentation and balancing and the fundamentals of automatic controls are covered in separate chapters. Of special importance is the chapter devoted to energy utilization and conservation in design, installation, and operation of air conditioning systems.

Two example projects in the design of a heating and cooling system are worked out in detail. Similar projects are suggested as hands-on learning experiences. These should be of value to those who are interested in installation, operation, and service as well as design, because they require the student to analyze how the system functions.

The author sincerely hopes that this presentation, based on his more than 55 years of experience in the field working for manufacturers, as a consulting engineer, and as an educator, will contribute to your knowledge and success in the HVAC industry.
