Dynamic Isolation Technologies in Negative Pressure Isolation Wards

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.

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.

XU Zhong-lin is a Senior Research Fellow of China Academy of Building Research. He served as Dean of Department of Air Cleaning Technology at HVAC Institute, Director of Quality Supervision and Inspection Center for Air Cleaning Project at the State Construction Engineering Quality Supervision and Inspection Center, Vice Chairman of Cleaning Technology Sub-committee of China Electronics Association, Invited member of GMP Committee for Ministry of Agriculture, Member of Biosecurity Technical Sub-Committee for Chinese National Laboratory Accreditation Board, etc. He was awarded with the State Council special allowance.

He continually devoted himself to the research of HAVC and air cleaning technology field over the past decades. He has created the theoretical system of cleanroom. He invented air filters for defense independently, and he was involved in the development of “Complete Equipment for Assembly Isothermal Cleanroom”. In recent years, he has created the concept of mainstream theory and leakage preventing layer theory, which has been successfully applied in the sanitary engineering projects. As for the theory and application problems in the air cleaning technology and engineering, he also made a lot of creative achievements which were more advanced than the research and engineering level abroad. He is one of the pioneers of China’s air cleaning technology, and he has made great contribution to promote the development of air cleaning technology and engineering in China.
