Preface

Theory, technique, measurement and equipment on pollution control of indoor particles (including microorganism) has been an important research area of Center for Cleaning Air Conditioning Technology from Institute of Building Environment and Energy at China Academy of Building Research (the former Air Cleaning Studio from Institute of HAVC at China Academy of Building Research), where the author worked and has been responsible for more than fifty years. The research in this field has been strengthened especially after the epidemic of “SARS” (Severe Acute Respiratory Syndrome). Many concepts have been proposed, which includes the corresponding theory and measurement of dynamic isolation (which is different from the past static isolation), the concept for preventing the entrance of dust particles and microbes into the room or the system (which is equivalent to the ideology for preventing the enemy from entering into the gate of the country), the concept of preventing and removing bacteria instead of killing bacteria, the combination of sealing and inducing, and the concept of se
