Más información sobre el libro

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.
