摘要

辽宁地区冬季自然通风条件受限,而通风又是解决由装饰装修导致室内甲醛浓度超标问题的有效手段,因此机械通风成为大众关注的焦点。为分析机械新风系统住宅冬季室内甲醛污染现状,文章选定辽宁地区8户装有新风系统的机械通风住宅,采用冬季典型气象日对住宅采用酚试剂-分光光度法分别在密闭工况和机械通风工况下在进行甲醛入户检测,以及使用Ikair传感器进行长期动态在线监测的方式获取室内甲醛浓度变化情况。根据对住宅的测试数据分析,发现开启新风系统能在一定程度上降低室内甲醛浓度。通过与以同样方式进行测试的21户自然通风住宅进行宏观效果比较发现,采用机械通风降低的室内甲醛浓度是采用自然通风的3.4倍。研究结果为辽宁地区冬季通风模式的选择提供参考。
        The natural ventilation conditions in Liaoning area are limited in winter, and ventilation is an effective means to solve the problem of excessive formaldehyde concentration caused by decoration. Therefore, mechanical ventilation has become the focus of public attention.In order to analyze the status of indoor formaldehyde pollution in mechanical fresh air system residences in winter, this paper selected 8 households equipped with fresh air system in Liaoning area.Through the typical meteorological days in winter, phenol reagent-spectrophotometry was used to detect formaldehyde in the residences under the closed condition and mechanical ventilation condition respectively, and the ‘Ikair' sensors were used for long-term dynamic online monitoring to obtain the change of indoor formaldehyde concentration.According to the analysis of the test data of the residences, it is found that opening the fresh air system can reduce the indoor formaldehyde concentration to a certain extent.Compared with the macroscopic effect of 21 naturally ventilated residences tested in the same way, it is found that the indoor formaldehyde concentration reduced by mechanical ventilation is 3.4 times than that by natural ventilation.The results provide a reference for the selection of winter ventilation modes in Liaoning area.
