【摘要】：空气负离子被誉为空气的“维生素”和“生长素”。在不同室外场所，已经被广泛用作室外空气质量的评价标准之一。而室内空气质量的评价，还局限在控制污染物的标准上，作为正面评价标准的空气负离子浓度尚未被广泛推广和使用。本文通过对建筑室内的负离子浓度和通风状态的研究发现，直接使用空气负离子浓度等相关指标对室内空气质量进行评价，评价能力略显不足，结果准确性较差。然而，可以使用室内空气负离子浓度指标对建筑室内通风状态进行评价，进而评价空气清新度和空气质量。因此，本文主要阐述基于空气负离子浓度的建筑室内通风状态的研究，其中也包括室内空气负离子浓度变化和其影响因子的研究。力图对建筑室内空气负离子作系统的研究，并探讨使之作为建筑通风设计的评价标准的能力，为室内环境作贡献。主要结论如下：（1）建筑室内外环境在空气负离子浓度上有明显差别；负离子浓度对于室内空气质量评价较为准确；单极系数q和安培空气质量指数CI的评价能力有限。（2）自然通风状态下的建筑室内空气负离子浓度最高，新风系统次之，封闭状态室内最低。在封闭状态下使用新风系统，或者改善自然通风，可以增加空气负离子浓度，从而提高室内空气负离子浓度和室内空气质量。（3）建筑室内空气负离子浓度与气候和室内相对湿度等因子关系较大；选用适合的舒适度调节系统，既能满足舒适度要求，又能保持室内空气负离子浓度。本文通过理论和实测相结合，，研究建筑室内空气负离子浓度和通风状态；为室内空气负离子在室内的研究作基础和补充。通过对比研究，探讨使用空气负离子评价建筑通风设计，从而改善室内环境。力求结合建筑设计方法，充分利用场地周围的空气负离子资源，发挥空气负离子——这种“空气维生素”的作用，进一步改善室内环境，创造健康宜居的生活环境。
[Abstract]:Air anion is known as the "vitamin" and "auxin" of air. It has been widely used as one of the evaluation standards of outdoor air quality in different outdoor places, and the evaluation of indoor air quality. The air negative ion concentration as a positive evaluation standard has not been widely used. Through the study of the negative ion concentration and ventilation condition in the building room, it is found that the evaluation ability of the indoor air quality is a little insufficient by directly using the air negative ion concentration and other related indexes to evaluate the indoor air quality. However, the indoor air negative ion concentration index can be used to evaluate the indoor ventilation status, and then to evaluate the air freshness and air quality. This paper mainly describes the study of indoor ventilation based on the concentration of air negative ions. It also includes the research on the change of indoor air negative ion concentration and its influence factors. It also tries to make a systematic study on indoor air negative ion concentration and discusses the ability to make it as the evaluation standard of building ventilation design. Contribute to the indoor environment. The main conclusions are as follows: 1) there are obvious differences in the air negative ion concentration in the indoor and outdoor environment of the building; The negative ion concentration is more accurate for indoor air quality evaluation. The evaluation ability of unipolar coefficient Q and amperometric air quality index CI is limited. 2) the concentration of negative ions in indoor air of buildings under natural ventilation is the highest, the fresh air system is the second, and the closed state is the lowest. In the closed state, the fresh air system is used, or the natural ventilation is improved. It can increase the air negative ion concentration and improve indoor air concentration and indoor air quality. 3) the concentration of negative ions in indoor air is closely related to the factors such as climate and indoor relative humidity. The suitable comfort regulation system can not only meet the requirement of comfort, but also maintain the concentration of negative ions in indoor air. In this paper, the anion concentration and ventilation state of indoor air are studied by combining theory with actual measurement. Through the comparative study, this paper discusses the use of air negative ions to evaluate the ventilation design of buildings, so as to improve the indoor environment, and strive to combine the architectural design method. Make full use of the air negative ion resources around the site, play the role of air negative ion-this "air vitamin", further improve the indoor environment, create a healthy and livable living environment.
