Abstract:

De nombreux travaux multicentriques ont permis d’évaluer le rôle des facteurs favorisants et des comorbidités dans l’asthme. L’étude des diverses manifestations fonctionnelles de l’asthme pendant le sommeil ont contribué à une meilleure compréhension physiopathologique. Il est établi que les modifications de la ventilation sont caractérisées par des anomalies ventilatoires dont la régulation est multifactorielle. La maladie asthmatique peut altérer la qualité du sommeil et générer un Syndrome d’Apnées Hypopnées Obstructives du Sommeil (SAHOS). La coexistence (fortuite ou induite par la même cause) de l’asthme et du SAHOS est assez fréquente. Le SAHOS perpétue l’inflammation systémique dans l’asthme et favorise son mauvais contrôle. L’inadéquation du contrôle de l’asthme est déterminante dans la gravité du SAHOS. Ainsi les interférences entre ces 2 affections demeurent complexes et nombreuses. Mots clés : Hypoxie, inflammation systémique, Asthme – SAHOS.

Abstract:

RÉSUMÉCette étude examine la relation entre, d'une part, la cohésion familiale, le contrôle subjectif, et trois formes de soutien social (soutien émotionnel, apport d'information, aide concrète), et, d'autre part, les stratégies d'adaptation utilisées par les mères de personnes séparées ou divorcées. Les données ont été obtenues auprès de 84 mères âgées de 45 à 78 ans (moyenne: 61). Deux analyses de régression multiple ont été conduites en utilisant l'adaptation de type évitement (accent mis sur la ventilation des émotions, sur le désengagement mental et comportemental) et l'adaptation de type implication active (adaptation active, planification, réinterprétation positive et croissance) à titre de variables critères. Un recours plus fréquent à l'adaptation de type évitement s'est avéré être associé à une faible cohésion familiale, un bas niveau de contrôle subjectif, et à un haut niveau de soutien émotionnel. De plus, une utilisation plus importante de l'adaptation active était associé à un haut niveau de soutien émotionnel.

Abstract:

El objetivo de este artículo es mostrar el proceso de creación de un modelo de predicción para el control de los dispositivos de ventilación pasiva en un clima cálido seco que, mediante un control manual adecuado de los sistemas de ventilación pasiva, logrará una temperatura menor compara- da con la temperatura en ausencia de ventilación en temporada de transición. Este artículo deriva de una investigación realizada en el Posgrado en Humanidades en la Universidad de Sonora. Los conceptos principales son predicción y control: la predicción es la clave del control e, incluso, de la modificación del curso de los acontecimientos. Se utilizó el método de regresión lineal, uno de los métodos de predicción científica más utilizado debido a la amplitud de su adaptabilidad, el cual consiste en un análisis estadístico para estudiar la relación entre variables. El modelo matemático se enfoca en la predicción de temperaturas interiores con base en temperaturas exte- riores. Se desarrolló a partir de la caracterización, por medio de mediciones, del comportamiento térmico de la vivienda estudiada y de las características del clima local. Mediante la correlación lineal y múltiple se desarrollaron fórmulas para predecir la temperatura interior horaria con base en las variables más significativas del exterior. La metodología seguida en esta investigación puede utilizarse para estudios y futura aplicación con el objetivo de lograr un ahorro energético. Esta investigación tiene la particularidad que fue realizada en clima cálido seco en un modelo de vivienda de tamaño real, por lo que puede ser útil para desarrolladores e investigadores.

Abstract:

Ventilation is an important aspect to maintain good indoor air quality in a building. However, excessive ventilation causing high energy consumption of the HVAC system. The ASHRAE Standard provides a guideline to set the ventilation rate that depends on the occupants' number and space. Thus, quantification of the number of occupants is required to regulate the ventilation rate. In this study, the estimated number of occupants was estimated using a Bayesian MCMC method based on CO2 levels. The mass balance equation of the CO2 is used as a model for the calculation of Bayesian MCMC. The Bayesian method for estimating the occupants' number is tested in a 96,7 m3 office room equipped with a ventilation system. Thus the occupancy estimation and control of ventilation can be done in real-time. The test also includes conventional ventilation control based on CO2 levels directly without converting to the occupants' number. The ventilation rate based on the number of occupants at the present test chamber refers to ASHRAE 62.1. The test results show that ventilation controlled by the estimated number of occupants using the Bayesian method successfully conducted with ventilation rate per occupant closer to the ASHRAE 62.1 standard over conventional ventilation method

Abstract:

Ventilation in buildings is the simplest and most convenient way to purify indoor air. However, when the ventilation is not enough due to natural ventilation, it should be cleaned by mechanical ventilation or air purifier. This process requires building energy. Therefore, it is possible to save the energy of the building by merely increasing the natural ventilation efficiency. This study conducted airflow analysis simulations to investigate the effects of changes in the shape of ventilation openings and louvers on the ventilation efficiency of a window ventilation system. The streamlined window opening exhibited a greater increase in airflow (41.3%) than did the conventional window (24.3%) for the ventilation model with four openings. It was also observed that flow separation and wakes were generated by the adverse pressure gradient arising from the increased airflow speed when a louver was employed. Based on these results, it can be concluded that using a louver as a wind augmentation device is an obstacle to improving the airflow in a window ventilation system.

Abstract:

Introduction : L’orthèse d’avancée mandibulaire (OAM) constitue une alternative efficace à la ventilation par pression positive continue (VPPC) chez les patients atteints de troubles respiratoires obstructifs du sommeil (TROS). Elle consiste en un dispositif endobuccal qui maintient la mandibule et la langue en position avancée, élargissant et stabilisant les voies aérifères supérieures (VAS) pendant le sommeil. Matériels et méthodes : Un examen clinique préalable, réalisé par le chirurgien-dentiste, permet de valider sa faisabilité et de sélectionner le type d’OAM le mieux adapté pour un patient donné. Après la pose du dispositif, une titration de l’avancée permettra d’optimiser son efficacité au travers de l’amélioration, voire de la disparition des symptômes cliniques subjectifs. Résultats : Un contrôle par polysomnographie ou polygraphie ventilatoire validera l’efficacité de ce traitement (réduction de l’Index d’Apnées Hypopnées (IAH), normalisation du taux d’oxygène sanguin, amélioration des principaux symptômes du TROS). Un suivi clinique sera nécessaire pour évaluer les résultats, les effets indésirables et l’observance thérapeutique à long terme. Ce traitement est efficace et bien toléré, et, à court terme, les principaux critères sont une réduction de l’index d’apnées hypopnées de plus de 50 % et une résolution complète des symptômes.

Abstract:

The modern people are active in various cultural facilities and enjoy the leisure life. The spectators and performers using a small concert hall generally use this space for about 2[Formula: see text]h in an enclosed state, and so the space should maintain a comfortable thermal environment and indoor air quality. The ventilation systems that can be applied to small concert hall are generally classified as the mixing ventilation system and the displacement ventilation system, but the upward displacement ventilation system is known to be able to maintain the clean indoor air quality with high energy efficiency. The upward displacement ventilation system installed in a dome-shaped small concert hall is not limited in the height of the vertical wall. Therefore, it is necessary to evaluate the optimal height of the return diffuser by utilizing the ventilation performance and the air diffusion performance index (ADPI). This study was carried out to evaluate the effect of the return diffuser position on the ventilation performance of an upward displacement ventilation system installed in a dome-shaped small concert hall. It was confirmed that as the height at which the return diffuser is installed on the vertical wall increases, the ventilation efficiency increases and the thermal stratification formed in the upper area is significantly reduced.

Abstract:

A numerical study has been conducted to simulate airflow and ventilation characteristics in the exhaust tower installed to ventilation of the multi-story underground parking lot. It is the objective of the present study to identify ventilation problems and to suggest the flow direction modifications of the ventilation system with the axial fan to improve ventilation efficiency in the low-rise section of the exhaust tower. Numerical results on SVE4 (scale of ventilation efficiency NO.4) and local mean age of exhaust ports are presented along with the location of axial fan on the direction of swirl flow and the dimension of exhaust tower. Ventilation system modifications on the direction of swirl flow have been suggested from the numerical results in order to prevent the flow interference by airflow discharged from the adjacent stories. The overall ventilation efficiency according to the rotational condition of the axial fans are compared quantitatively using the concept of SVE4 calculated by means of tracer gas pulse method to investigate distribution characteristics of the air discharged from each story among the exhausted air to the two exhaust ports in the narrow exhaust tower.

Abstract:

Natural ventilation is gaining more attention from architects and engineers as an alternative way of cooling and ventilating indoor spaces. Based on building types, it could save between 13 and 40% of the building cooling energy use. However, this needs to be implemented and operated with a well-designed and integrated control system to avoid triggering discomfort for occupants. This paper seeks to review, discuss, and contribute to existing knowledge on the application of control systems and optimisation theories of naturally ventilated buildings to produce the best performance. The study finally presents an outstanding theoretical context and practical implementation for researchers seeking to explore the use of intelligent controls for optimal output in the pursuit to help solve intricate control problems in the building industry and suggests advanced control systems such as fuzzy logic control as an effective control strategy for an integrated control of ventilation, heating and cooling systems.

Abstract:

With the continuous development and progress of the mining industry, various technologies in mining engineering have gradually developed towards the intelligent stage, and the ventilation system is no exception. Since ancient times, mine ventilation has been a necessary part of mining engineering, and so the optimization of mine ventilation undoubtedly plays a great role in mining production. This two-part opinion paper briefly introduces the development of the intelligent ventilation in mining engineering and serves as a guide to the Tossing out a brick to get a jade gem, with implications for both the development and the future of the underground mine ventilation systems. Finally, in the second part of the paper, we explain why we think ZigBee WSN technology is the best choice in intelligent ventilation systems in underground mines at the present stage.

Abstract:

In this study, we analyze the impact of ventilation heat recovery with the heating and cooling potential of earth air heat exchanger in real climatic conditions in domestic buildings in the Middle Atlas region. In our case study, we calculate the primary energy used by a domestic building built as per the conventional house design parameters required by the Moroccan regulation. We use climate data for the city of Fes in Northern Moroccan. Three system configurations were considered. The first was the mechanical extract ventilation system both with and without heat recovery. The second was the mechanical extract ventilation system with earth to air heat exchanger system (EAHEX), and the third system was the mechanical balanced ventilation system coupled with EAHEX system. Primary energy use strongly influences natural resources efficiency and the environmental impacts of energy supply activities. In this study we explore the primary energy implications of the mechanical balanced ventilation system coupled with the EAHEX system in residential buildings. The results of this study shows that the use of a balanced ventilation system, with a high efficiency instead of a mechanical extract ventilation system, decreases the final and primary energy consumption. Moreover, it decreases or increases the CO2 emission depending on the primary energy sources.

Abstract:

Displacement ventilation is a proven method of providing conditioned air to enclosed spaces with the aim to deliver good air quality and thermal comfort while reducing the amount of energy required to operate the system. Until now, the practical applications of displacement ventilation have been exclusive to providing ventilation and cooling to large open spaces with high ceilings. The provision of heating through displacement ventilation has traditionally been discouraged, out of concern that warm air supplied at the floor level would rise straight to the ceiling level without providing heat to the occupied space. Hence, a separate heating system is regularly integrated with the displacement ventilation in cold climates, increasing the cost and energy use of the system. This paper goes beyond the common industry practice and explores the possibility of using displacement ventilation to provide heating without any additional heating system. It reports on experimental investigations conducted in laboratory and field settings, and numerical simulation of these studies, all aimed at investigating the application of displacement ventilation for providing a comfortable indoor environment in winter by preheating the space prior to occupancy. The experimental results confirm that the proposed concept of providing space heating in unoccupied periods without a separate heating system is possible with displacement ventilation.

Abstract:

In the air distribution design of a small theater, either a downward or an upward displacement ventilation is applied generally. The cool air is supplied from openings distributed over the ceiling and extracted beneath the seats for the downward flow and supplied from beneath the seats and extracted from the ceiling for the upward flow system. By the change of air exchange rate (ACH) produced by two divergent ventilation systems inside theater, thermal comfort and ventilation effectiveness around the seats show a different phenomenon. Thereby, it can be seen that the selection of the ventilation system is a significant factor in energy saving. CFD calculations for this study were performed to investigate the effects of various parameters (ADPI and ACE) of air distribution system applied in order to save the cooling energy. This paper focuses mainly on the effect of the varied volume flow rate depending on the ventilation system. The ventilation performances of the downward displacement system are compared quantitatively with the upward displacement system using the concept of the LMA of fresh air.
