Features: In addition to temperature, humidity is another important indicator for measuring the comfort of the building environment. Independent control of humidity represents the future direction of air conditioning development. This book focuses on dehumidification technology in air conditioning, supplemented by dehumidification in other industrial sectors, systematically elaborating on the classification, principles, and applications of dehumidification technology. The book is divided into 9 chapters, providing a detailed discussion on the concept of dehumidification, its physicochemical characteristics, the impact of humidity on thermal comfort in artificial environments, methods for calculating dehumidification load, and the principles and methods of various dehumidification technologies. The book summarizes some relatively mature dehumidification methods, such as spray chamber dehumidification, cooling coil dehumidification, liquid dehumidification, and solid adsorbent dehumidification, while also describing recent advancements in these methods both domestically and internationally. Additionally, drawing on the author's years of research, the book discusses the principles and characteristics of novel dehumidification methods (such as rotating wheel dehumidification and membrane dehumidification). Starting from the mechanism of heat and moisture transfer, the book analyzes performance improvement methods for various dehumidification technologies, provides thermodynamic calculation processes, and offers a foundation for system simulation and engineering optimization design to enhance theoretical guidance for engineering design. For the convenience of readers' learning and understanding, the book briefly introduces the properties of moist air and humidity measurement and control technology at the beginning. This book can serve as a course textbook for Ph.D. and master's students, as well as senior undergraduate students in related fields such as refrigeration, air conditioning, chemical engineering, environmental science, and energy. It can also be used as an important reference for engineering technicians engaged in the design, installation, and management of these fields.
