室内空气品质预测属于主观判断,预测结果的准确性取决于评价方法的可靠性、预测模型的合理性、预测条件与实际条件的吻合程度等因素。文章分析了常用的室内空气品质预测方法中存在的问题,根据室内空气品质不满意率和化学污染物对数评价指标间的线性关系,在室内污染物浓度场预测的基础上提出了一种预测室内空气品质的新方法。 相似文献

为了了解广州市公共建筑客房的室内空气品质状况,本文对不同类型客房的室内空气进行了检测,并采用SPSS12.0软件对数据进行了分析,同时用空气质量综合指数法对其进行了综合评价。结果表明:客房内物理性参数大部分在合格范围内,冬季室内物理性参数超标率较大,对于各房间,风速分布差异显著;客房内的空气属于未污染,各参数实测的平均浓度均在室内空气质量标准的规定范围内,各参数的指数在0.27~0.63之间,超标率较低;对于不同的房间,室内的CO、CO2、PM10的实测浓度与指数分布无显著性差异(P实测=0.014~0.516〉0.01,P指数=0.060~0.601〉0.01),而甲醛和细菌总数的实测浓度与指数分布差异显著。 相似文献

This paper reviews the published literature on indoor thermal environment and air quality in Chinese-style residential kitchens (CRKs). The paper first discusses typical characteristics of CRKs, including kitchen layout, cooking methods, and ventilation systems used. Next, the paper describes the current state of the indoor thermal environment and air quality in CRKs. Finally, this paper summarizes measures to control and improve the environment inside CRKs. The results indicate that the indoor environment of CRKs is too hot in summer and exhibits a large vertical temperature difference. No appropriate model was available for accurately evaluating the thermal environment in CRKs. At the same time, CRKs are highly polluted by COx, NOx, TVOC, and particulate matter (PM). Although existing exhaust hoods could improve the indoor environment to some extent, the use of a combined exhaust, make-up air, and air-conditioning system should be considered to provide a comfortable and healthy environment in CRKs. 相似文献

To improve indoor air quality and to protect public health, Taiwan has enacted the “Indoor Air Quality Act (IAQ Act)” in 2012. For the general public, the indoor air quality in hair salons is important because it is a popular location that people will often visit for hair treatments. However, only a few exposure assessments regarding air pollutants have previously been performed in hair salons. To assess the air quality of hairdressing environments in Taipei, ten hairdressing salons were included for a walk‐through survey in this study. In addition, the airborne concentrations of formaldehyde, volatile organic compounds (VOCs), CO2, and phthalate esters were also determined in 5 salons. Charcoal, XAD‐2, and OVS‐Tenax tubes were used for the air sampling, while the samples were analyzed with gas chromatography/mass spectrometer. It was found that the products used in hair salons contained various chemicals. In fact, from the walk‐through survey, a total of 387 different ingredients were found on 129 hair product labels. The hair salons were not well ventilated, with CO2 levels of 600 to 3576 ppm. The formaldehyde concentrations determined in this study ranged from 12.40 to 1.04 × 103 μg m?3, and the maximum level was above the permissible exposure limit (PEL) of US Occupational Safety and Health Administration (US OSHA). Additionally, 83% of the samples were with levels higher than the standard regulated by Taiwan's IAQ Act. The concentrations of VOCs and phthalate esters were below the occupational exposure limits (OELs), but higher than what was found in general residential environments. The hair products were considered as the major source of air pollutants because significantly higher concentrations were found around the working areas. The number of perming treatments, the number of workers, and the frequency of using formaldehyde releasing products, were found to be associated with the levels of formaldehyde. This study indicates that efforts are needed to improve the indoor air quality in hairdressing salons in Taipei. 相似文献
