EBOOK - Kiểm tra và cân bằng hệ thống HVACR 5th Edition (Samuel C. Monger) - 404 Trang.
This book will provide the reader with an understanding of the principles and practices of testing and balancing (TAB) heating, ventilating and air conditioning (HVAC) air and water systems. For those interested in getting into TAB or are new to the HVAC industry it’s a text for learning more about HVAC systems and testing and balancing.
For the mechanical engineer, building owner, facility manager or energy manager this book can be used for teaching TAB, writing more effective pecifications, and learning about TAB and how it interacts with system commissioning, indoor air quality and energy management. It is the intent of this book to improve the communications between owners, mechanical engineers, designers, vendors, contractors and TAB engineers, supervisors, and technicians to ensure that HVAC systems are being properly tested and balanced.
