Air Conditioning Principles

This book explores the fundamental concepts of air conditioning and their application to systems. The book explains all concepts in a clear, practical manner, and focuses on problems and examples typically encountered on the job. Uses a minimum of mathematics.

This is a new edition of the standard air conditioning installation/service text, emphasizing energy conservation. It contains new material on heating and computer programs, and new load calculation problems. The book provides thorough coverage of the fundamentals of air conditioning, explains relationships of theory to design of new systems, and discusses troubleshooting of existing systems. Air conditioning and refrigeration equipment and systems, and refrigeration absorption systems and heat pumps are all covered. Computer programs for load estimating are also described, and there are many illustrative examples of real-world situations. The text is consistent with all ASHRAE load estimating guidelines.

This book presents the most current design procedures in heating, ventilation and air conditioning (HVAC), available in handbooks, like the ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) Handbook-2013 Fundamentals, in a way that is easier for students to understand. Every effort is made to explain in detail the fundamental physical principles that form the basis of the various design procedures. A novel feature of the book is the inclusion of about 15 worked examples in each chapter, carefully chosen to highlight the diverse aspects of HVAC design. The solutions for the worked examples clarify the physical principles behind the design method. In addition, there are problems at the end of each chapter for which numerical answers are provided. The book includes a series of MATLAB programs that may be used to solve realistic HVAC design problems, which in general, require extensive and repetitive calculations.

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.

Heating Ventilation and Air Conditioning by J. W. Mitchell and J. E. Braun provides foundational knowledge for the behavior and analysis of HVAC systems and related devices. The emphasis of this text is on the application of engineering principles that features tight integration of physical descriptions with a software program that allows performance to be directly calculated, with results that provide insight into actual behavior. Furthermore, the text offers more examples, end-of-chapter problems, and design projects that represent situations an engineer might face in practice and are selected to illustrate the complex and integrated nature of an HVAC system or piece of equipment.
