Kanabus-Kaminska and published by . This book was released on 1996 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new small chamber (1.0 by 0.8 by 0.5 m) test system was developed to investigate the effect of local airflow conditions on the emission rates of volatile organic compounds (VOCs) from commonly used building materials and furnishings. The uniqueness of the new chamber is that it can provide controlled mean air velocity and turbulence level over the surface of the tested material in addition to air temperature, relative humidity, air change rate, and chamber loading as in small test chambers. This paper presents the design, construction, and performance data of this new test chamber system. In addition, VOC emissions from a wood stain were tested using the new small chamber under two different air-velocity conditions. A new procedure was developed to determine the interfacial mass transfer coefficient based on the concentration data measured at the outlet of the chamber. The results indicated that the interfacial mass transfer coefficient and hence the emission rate increased with the air velocity over the material surface when other parameters, such as air temperature, relative humidity, chamber loading, and air change rate were kept unchanged. This confirms the importance of controlling the local velocity and turbulence level over the material surface in conducting emission tests using small-scale environmental chambers in order to better understand and interpret the test results.

Available in PDF, EPUB and Kindle. Book excerpt: People live in indoor environment about 90% of lifetime and an adult inhales about 15 kg air each day, over 75% of the human body’s daily mass intake (air, food, water). Therefore, indoor air quality (IAQ) is very important to human health. This book provides the basic knowledge of IAQ and highlights the research achievements in the past two decades. It covers the following 12 sections: introduction, indoor air chemicals, indoor air particles, measurement and evaluation, source/sink characteristics, indoor chemistry, human exposure to indoor pollutants, health effects and health risk assessment, IAQ and cognitive performance, standards and guidelines, IAQ control, and air quality in various indoor environments. It provides a combination of an introduction to various aspects on IAQ studies, the current state-of-knowledge, various advances and the perspective of IAQ studies. It will be very helpful for the researchers and technicians in the IAQ and the related fields. It is also useful for experts in other fields and general readers who want to obtain a basic understanding of and research advances in the field of IAQ. A group of experts in IAQ research have been recruited to write the chapters. Their research interests and experience cover the scope of the book. In addition, some experienced experts in IAQ field have been invited as advisors or reviewers to give their comments, suggestions and revisions on the handbook framework and the chapter details. Their contribution guarantees the quality of the book. We are very grateful to them. Last but not least, we express our heartfelt thanks to Prof. Spengler, Harvard University, for writing the foreword of the current Handbook of Indoor Air Quality both as a pioneer scientist who contributed greatly to indoor air science and as an Editor-in-chief of Handbook of Indoor Air Quality 2001, 1st ed. New York: McGraw-Hill. In addition to hard copies, the book is also published online and will be updated by the authors as needed to keep it aligned with current knowledge. These salient features can make the handbook fresh with the research development.

Available in PDF, EPUB and Kindle. Book excerpt: Building materials and furnishings emit a wide variety of indoor pollutants, such as volatile organic compounds (VOCs). At present, no accurate models are available to characterize material emissions and sorption under realistic indoor conditions. The objective of this thesis is to fill that gap. Using the emission data measured in small-scale and full-scale environmental chambers, this investigation has developed a numerical model for simulating emissions of "wet" materials applied to porous substrates. This model considers VOC mass transfer processes in the air, material-air interface, material film, and the substrate. The model can predict "wet" material emissions under different environmental conditions (i.e., temperature, velocity, turbulence, and VOC concentration in the air) with reasonable accuracy. We developed two models for simulating VOC emissions from dry materials. One is a numerical model for short-term predictions, the other is an analytical model for long-term predictions. The models have been successfully used to examine the VOC emissions from two particleboard samples and a polypropene Styrene-Butadiene Rubber (SBR) carpet. A VOC sorption model has also been developed to analytically solve the VOC sorption rate as a function of air-phase concentrations. The model has been validated using an analytical solution as well as data obtained from sorption experiments. The emission and sorption models that we developed have been further used to study indoor air quality (IAQ) in a small office with different ventilation systems. The results show that displacement ventilation may not provide better IAQ than mixing systems if the VOC sources are from the floor. Further, our study shows sink effects from internal walls of gypsum board.

Available in PDF, EPUB and Kindle. Book excerpt: It is important to know both the emission and the sorption behavior of materials when constructing or renovating buildings in order to avoid material related indoor climate problems. With a general, low-cost test method, the sink effect of materials under normal conditions can be incorporated as information in an indoor climate labeling system for materials. Reconditioned samples of waterborne paint applied on tinned steel plates and carpet were placed in small test chambers at a controlled air exchange rate and mean air velocity. The sorption behavior of the materials was studied, while ambient air from a recently renovated office environment was passed through the chambers. The desorption of VOCs from the test samples was analyzed chemically and by sensory evaluation. The results showed a correlation between the chamber concentration in the desorption phase expressed as the percentage of the concentration in the office air and the gas chromatographic retention times of the VOCs (using a semipolar column). The results are used to propose a general test method for assessing the sink effects of materials used in the indoor environment. A mixture of pollutants with affinities to indoor surfaces is proposed for adsorption testing under controlled environmental conditions. A mathematical model of the distribution of emitted VOCs between indoor air and sinks is proposed. It is possible to calculate the impact of the sinks on the indoor air quality by comparison with indoor relevant thresholds for odor and mucous membrane irritation.

This book was released on 2001 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorption of volatile organic compounds (VOCs) by building materials can have significant effect on the indoor VOC concentration levels and indoor air quality in buildings. The objective of this study was to investigate experimentally the effects of environmental conditions (temperature, humidity and air velocity) on the sorption rate and capacity of three typical types of building materials (carpet, ceiling tile and painted drywall), and to evaluate existing sorption models with experimental data. A small-scale chamber test system has been developed in this study to conduct sorption tests under different environmental conditions. The sorption data collected were analyzed by three different analysis methods: the integration method, the linear Langmuir model method and the diffusion model method. The results of the integration method indicated that for the painted drywall, the differences among different environmental conditions were so small compared with the experimental uncertainties that no statistically significant environmental effect could be observed at 95% confidence level. The sorption of VOCs on ceiling tile decreased with the increase of the air velocity and temperature, but did not change significantly with the relative humidity. The sink strength of benzaldehyde under high humidity was much stronger than any other conditions. The sorption of VOCs on carpet appeared to be a diffusion-controlled process. With the increase of temperature, the diffusion coefficient increased while the partition coefficient decreased. A higher air velocity increased the sink capacity of dodecane on carpet. The relative humidity had no significant effect on the sorption of VOCs on carpet. Based on the model evaluation conducted in this study, the linear Langmuir model appeared to be suitable for painted drywall and ceiling tile while the diffusion model is more suitable for carpet.
