摘要
ASHRAE在2020年4月更新了传染性气溶胶的立场文件,本次更新删繁就简,缩减了背景及传播机理的篇幅,在保留上一版(2014版)大部分建议措施的基础上,引入证据级别分级制,量化各措施可信度,具备更强的可操作性和指导性。本文逐章节概括更新前后的差异点,从建议措施中筛选出平疫转换预留设计、紫外线消毒灭菌、个性化通风三方面进行重点解读,分析技术利弊,提出措施应用时的注意事项,供工程师、研究人员参考。
ASHRAE updates the position document on infectious aerosols in April 2020.This updated document is simplified by reducing the length of the background and the mechanism of virus transmission.On the basis of retaining most of the recommended measures from the previous version(2014 version),the new document introduces the evidence-level grading system to quantify the credibility of various measures,which has made it more operable and instructive.This paper summarizes the differences before and after the update chapter by chapter,and selects three aspects of the recommended measures from the new document,namely,the reserved design for the pandemic-era,ultraviolet sterilization,and personalized ventilation.This paper analyses the pros and cons of the measures,and provides the precautions for the application of the measures,which provides a reference for the engineers and researchers.
