舒适性空调系统的临界净化效率与最小换气次数

Critical filtration efficiency and the minimum air changes of comfort air conditioning systems

指出舒适性空调应同时满足健康和舒适要求 ,从室内空气中有害物质量平衡方程导出舒适性空调系统临界净化效率和最小换气次数 ,认为依靠增加新风量来改善室内空气品质的作用是有限的 ,在满足室内要求的基本新风量后 ,提高各级空气净化器效率才有助于改善空气品质。

Points out that the comfort air conditioning should meet the requirements for health and comfort at the same time. Derives the critical filtration efficiency and the minimum air changes of a comfort air conditioning system from the mass balance equation of indoor air contaminants. Considers that the effect of improving indoor air quality by increasing fresh air volume is limited. On the base of meeting the basic indoor requirement for fresh air, increasing the cleaning efficiency of all air cleaners can improve indoor air quality. Claims that if the author's opinion is put into practice, air conditioning system design would be better than that by traditional methods.
