Features: This is the third edition of the monograph Air Cleaning Technology Principles, originally published in 1983. Compared to the 1983 edition, it not only reflects the latest technological achievements but also emphasizes the systematic theoretical framework and the guiding role in solving practical problems. The book systematically establishes the theoretical system of cleanrooms, introducing for the first time many new concepts and methods such as cleanroom characteristic indicators, uniform and non-uniform distribution characteristics, minimum detection capacity, new concepts of fresh air treatment, and the theory of the leakage barrier. It summarizes the author's nearly 40 years of research achievements and insights. Its theoretical depth, novelty, and systematic nature make it a reference book for technicians, researchers, and students in the fields of air conditioning and purification. The book is also suitable for professionals in environmental protection, pharmaceuticals, food, textiles, electronics, instruments, aerosols, fine chemicals, atmospheric physics, biotechnology, agricultural engineering, and cultural heritage preservation. The book is divided into 17 chapters, systematically discussing the fundamental principles of air cleaning technology, with main content including:
Particle distribution characteristics;
Characteristics of atmospheric dust and the distribution patterns of China's atmospheric dust;
Properties of suspended particles and their movement within a room;
Filtering mechanisms and the various characteristics of filters, as well as the structural design and calculations for high-efficiency filters;
The theoretical foundation of air cleanliness levels and their relationship with product yield;
The principles, characteristics, calculation theories, and specific methods for industrial cleanrooms, biological cleanrooms, local clean areas, mainstream areas, and leakage barriers;
Sampling and detection theories and methods.
The book also provides data for design and testing, along with formulas, calculation methods, and steps. Each chapter concludes with references, and the book includes a bilingual (Chinese-English) and everyday terminology and an index at the end.
