HVAC Chillers - (second edition)

HVAC chillers are complex systems that combine thermodynamics, heat transfer, fluid mechanics, controls, and mechanical engineering. Understanding how these systems operate, how they are designed, and how they can be optimized is essential for engineers, technicians, and facility managers responsible for building performance.

This book was written to provide a practical and structured understanding of HVAC chillers. It explores the fundamental principles of refrigeration, explains different types of chillers, and describes how chilled water systems are designed and operated. In addition, the book addresses important topics such as energy efficiency, plant optimization, system controls, and maintenance strategies that help ensure reliable and efficient operation.

Modern cooling systems are increasingly influenced by sustainability goals, stricter environmental regulations, and the need for higher operational efficiency. As a result, chiller technology is evolving rapidly, with innovations such as variable speed compressors, magnetic bearing systems, advanced controls, and low-GWP refrigerants shaping the future of cooling.

This book aims to bridge theory and practice. It is designed not only to explain how chillers work, but also to provide insights that professionals can apply in real-world HVAC projects.
