By comparing theoretical and measured data, it highlights the mainfeatures of air purifiers and key points in the design process for different applications. Calculation methods for the indoor particle concentration and the self-purification time are also provided. The book describes the conditions for window opening in smog and for selecting air purifiers, and proposes a newmethod for improvingtheir measurement. In closing, it includes a new assessment index. \u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Zhonglin Xu\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9811325316\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789811325311\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Springer\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 09\/19\/2018\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 143\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.88lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.21h x 6.14w x 0.44d","brand":"Zhonglin Xu","offers":[{"title":"Hardcover","offer_id":48487218512127,"sku":"9789811325311","price":129.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_aedea969-c91f-4187-89b9-8ed07598af51.jpg?v=1778059112","url":"https:\/\/www.whiterainbookhouse.com\/products\/air-purifier-zhonglin-xu-9789811325311","provider":"WR Book House","version":"1.0","type":"link"}
