“…[45][46][47][48][49][50][51] Some models now allow taking into account the influence of the intricate geometries of certain indoor surfaces on the rate of uptake of gaseous pollutants. Recently, Mendez et al 37 implemented in INCA-Indoor a scheme proposed by Blondeau et al 52 involving the use of the mass transfer coefficients from indoor air into a boundary layer near the surfaces. Indeed, several indoor measurement campaigns did not give enough details about the experimental condi ons and the geometries of indoor surfaces.…”

Assessment of indoor HONO formation mechanisms based on in situ measurements and modeling

The photolysis of HONO has been found to be the oxidation driver through OH formation in the indoor air measurement campaign SURFin, an extensive campaign carried out in July 2012 in a classroom in Marseille. In this study, the INCA-Indoor model is used to evaluate different HONO formation mechanisms that have been used previously in indoor air quality models. In order to avoid biases in the results due to the uncertainty in rate constants, those parameters were adjusted to fit one representative day of the SURFin campaign. Then, the mechanisms have been tested with the optimized parameters against other experiments carried out during the SURFin campaign. Based on the observations and these findings, we propose a new mechanism incorporating sorption of NO onto surfaces with possible saturation of these surfaces. This mechanism is able to better reproduce the experimental profiles over a large range of conditions.

“…The INCA‐Indoor model used in this study is a box time‐resolved numerical model developed in order to understand the physical and chemical processes leading to indoor air pollution and to identify their contributions to pollutant concentrations . This model takes into account constant emissions from building materials, sorption processes, gas‐phase chemical reactions (SAPRC 07), and one heterogeneous reaction at the surface of the materials (reaction of NO 2 that produces HONO), as well as outdoor air exchange.…”

“…However, in order to better predict VOC concentrations indoors and to anticipate the impact of applied strategies on the reduction in pollutant concentrations, parameters that allow the modeling of interactions between VOCs and surfaces are needed, in particular because the surface‐to‐volume ratio is high indoors . With this in context, the MERMAID project (mesures expérimentales représentatives et modélisation air intérieur détaillée/representative experimental measurement‐indoor air detailed model) combined experimental in situ measurements and modeling based on the detailed indoor air quality model INCA‐Indoor, which includes both physical and chemical processes . This work will particularly focus on the in situ experimental characterization of the physical interactions (emission and sorption) between VOCs and surfaces and the assessment of their impact on VOC concentrations by modeling.…”

The assessment of VOC emission rates and sorption coefficients was performed for ten surfaces present within a classroom, using field and laboratory emission cells (FLEC) coupled to online and off-line VOC quantification techniques. A total of 21 identified VOCs were emitted by the different surfaces. VOC emission rates measured using PTR-ToF-MS were compared to gas chromatographic measurements. The results showed that the two methods are complementary to one another. Sorption parameters were also successfully measured for a mixture of 14 VOCs within a few hours (<17 hours per surface). A study of the spatial and temporal variability of the measured parameters was also carried out on the two surfaces that presented the most potential for interaction with VOCs, accounting for the largest surface areas within the room. The dataset of emission rates and sorption parameters was used in the INCA-Indoor model to predict indoor air concentrations of VOCs that are compared to experimental values measured in the room. Modeling results showed that sorption processes had a limited effect on indoor concentrations of VOCs for these field campaigns. Modeled daily profiles show good agreement with the experimental observations for VOCs such as toluene (indoor source) and xylenes (outdoor source) but underestimate concentrations of methanol (both indoor and outdoor sources).

“…It includes all the interior space of daily life and work, such as offices, conference rooms, classrooms, hospitals and other indoor space environment and hotels, shops, theaters, libraries, stadiums, gymnasiums, dance halls, and other indoor public places and civil aircraft, passenger cars, trains and other transport. Some new ideas now suggest that indoor microclimate should also include indoor work and production sites [8]. In the standard ASHRAE62-1989 issued by the American Society of Heating, Refrigeration and Air Conditioning Engineers, an acceptable concept of indoor air quality is proposed, which basically improves the definition of indoor air quality.…”

Abstract. The paper summarizes the achievements and problems of indoor air quality research at home and abroad. The pollutants and pollution sources in the room are analyzed systematically. The types of building materials and pollutants are also discussed. The physical and chemical properties and health effects of main pollutants were analyzed and studied. According to the principle of mass balance, the basic mathematical model of indoor air quality is established. Considering the release rate of pollutants and indoor ventilation, a mathematical model for predicting the concentration of indoor air pollutants is derived. The model can be used to analyze and describe the variation of pollutant concentration in indoor air, and to predict and calculate the concentration of pollutants in indoor air at a certain time. The results show that the mathematical model established in this study can be used to analyze and predict the variation law of pollutant concentration in indoor air. The evaluation model can be used to evaluate the impact of indoor air quality and evaluation of current situation. Especially in the process of building and interior decoration, through preevaluation, it can provide reliable design parameters for selecting building materials and determining ventilation volume.
