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。据作者的观点设计空调系统其方法将有别于传统设计 It is pointed out that comfort air conditioning should meet the requirements of health and comfort at the same time. Based on the balance equation of harmful substances in indoor air, the critical purification efficiency and the minimum ventilation times of comfort air conditioning system are derived. The effect of improving the indoor air quality by adding fresh air is limited , To meet the basic requirements of the indoor air volume, improve the efficiency of air purifiers at all levels will help improve the air quality. According to the author’s point of view the design of air-conditioning systems approach will be different from the traditional design
