The assimilation potential (assimilative capacity) of the atmosphere can be represented in two ways: one as the ventilation coefficient and the other as the dispersion potential of emission loads discharged into the region. In the present study, the atmospheric assimilation potential of a typical urban area in Kochi city has been determined with respect to sulfur dioxide (SO(2)). The ventilatio...
Background & objective: Industrial ventilation systems and dust collectors are effective solutions to reduce particulate emissions in the workplace and environmental in mineral processes. In this study, Local Exhaust Ventilation System and dust collectors for control of emitted silica, coke, silicon carbide dusts from crushing unit was designed and evaluated. Methods: : Local Exhaust venti...
Introduction: Adherence to the design values and ventilation standards (VS) after installing and also maintaining continuous work of ventilation system with maximum performance throughout its life are amongst the reasons of ventilation systems monitoring. Therefore, the aim of this study was to evaluate performance of local exhaust ventilation system for control of dust by measuring the operati...
Background & Objectives : Hospital indoor air contains a wide range of airborne pathogenic bioaerosols which have a significant impact on health care staff’ health and welfare. The aim of this study was to assess the effects of ventilation system types on occupational exposure of the health care staffs to airborne bioaerosols in the isolation room based on the patient bed arrangements and...
introduction: tuberculosis (tb), with different types of respiratory tract involvements, has a high rate of mortality all around the world. endobronchial involvement, which is a slightly common tuberculous infection, requires special attention due to its severe complications such as bronchostenosis. aim of study of this study was describes, one type of pulmonary tuberculosis with less diagnosed...
Air flow in ducts is one of the basic processes ventilation and air conditioning. Knowledge this phenomenon laws according to it indispensable for drawing up sizing calculations duct networks, determining energy needed move as well aerodynamic parameters related ducts. Industrial buildings include large spaces with various sources releases harmful substances. Type these their location depends o...
spreading wood particles and attached colored materials in work places can cause many problems for woodwork industry workers. the aim of this study is to design and implement a local exhaust ventilation system to control wood dust and isocyanates simultaneously. the study was conducted on 18 workers in the paint workroom of a wood door industry. at first, an overview of the workplace indoor air...
I applied well-known hierarchical clustering algorithms to datasets of workstation activity during fiveminute intervals recorded over periods of time ranging from 9 days to one month. I grouped together workstations into ventilation subsystems based on the usage data as well as static pressure values measured in the factories. In simulations, I achieved significant energy savings even when the ...
