In the realm of building automation, fan coil units (FCUs) stand as versatile and efficient solutions for providing comfortable indoor air quality. These compact, self-contained units utilize a combination of a fan, a heat exchanger, and controls to deliver conditioned air to individual spaces within a building. Their adaptability and energy-efficiency have made them a popular choice for various applications, ranging from residential homes to commercial and industrial structures.

This book aims to provide a comprehensive understanding of fan coil units, encompassing their fundamental principles, design, operation, applications, and maintenance. It delves into the intricacies of each component, from the centrifugal fan responsible for air circulation to the heat exchanger that facilitates heat transfer. It explores the different types of FCUs, their modes of operation, and their integration with building automation systems (BAS).

The book also delves into the practical aspects of designing, installing, and maintaining FCU systems. It outlines considerations for system selection, ductwork layout, and refrigerant piping for hybrid FCUs. It guides readers through the installation procedures, commissioning processes, and maintenance protocols.

Throughout the book, real-world case studies are incorporated to illustrate the successful implementation of FCU systems in various settings. These case studies showcase the practical applications of FCUs, highlighting their ability to enhance comfort, optimize energy consumption, and contribute to sustainable building practices.

As the HVAC industry continues to evolve, embracing advancements in technology and sustainability, the role of fan coil units is poised to grow. This book endeavors to equip readers with the knowledge and tools to harness the potential of FCUs in creating comfortable, efficient, and eco-conscious built environments.
