This book presents novel design principles and technologies for dynamic isolation based on experimental studies. These approaches have now become the local standard in Beijing and are currently being promoted for use nationwide. Further, the book provides details of measures and guidelines for the design process. Departing from the traditional understanding that isolation wards should be designed with high negative pressure, airtight doors and fresh air, it establishes the basis for designing biological clean rooms, including isolation wards, using a simple and convenient scientific approach. This book is intended for designers, engineers, researchers, hospital management staff and graduate students in heating ventilation air conditioning (HVAC), air cleaning technologies and related areas. Inhaltsverzeichnis Importance of negative pressure isolation ward.- Three misunderstandings in design process of negative pressure isolation ward.- Principle and technology of dynamic isolation.- Air distribution design in negative pressure isolation ward.- Determination of air change rate in negative pressure isolation ward.- Safety of exhaust and return air is prerequisite.- Design essentials for negative pressure isolation ward.

Focusing on the development and application of portable air purifiers in China, this book delves into their theoretical characteristics under various conditions. It critiques the inadequacy of the "Clean Air Delivery Rate" in addressing operational issues and presents a comparison of theoretical versus measured data. Key design features and calculation methods for indoor particle concentration and self-purification time are discussed. Additionally, it offers guidance on using air purifiers during smog and introduces a novel assessment index for improved measurement.

This book delves into the principles and technologies of air cleaning, specifically tailored for cleanroom environments. It covers various air filtration methods, their effectiveness, and the critical role they play in maintaining stringent cleanliness standards. The text also explores the design and operational considerations necessary for implementing air cleaning solutions in cleanrooms, making it a valuable resource for professionals in industries such as pharmaceuticals, biotechnology, and electronics.
