Control of CO2 in a naturally ventilated classroom ...

· This study will examine the methods of control in a naturally ventilated classroom over several days with differing conditions so that the classroom ventilation performance could be assessed against current recommendations and compare the measured values against a simple computer model. 2. Effect of CO 2 on learning ability and attendance. High levels of CO 2 have been shown to cause a ...

Carbon Dioxide (CO2) Safety Program

Program (a site CO2 Identification and Control Program), the first step in controlling and preventing hazardous levels of carbon dioxide accumulation. Identify operational areas where CO2 can collect, and then develop procedures and methods to ensure that CO2 is dispersed to safe levels. Learn how and when to use all three types of electronic monitors – review your exposures and then decide ...

Robust Resource Management Control for CO2 Emission and ...

With the increasingly severe global warming, investments in clean technology, reforestation and political action have been studied to reduce CO2 emission. In this study, a nonlinear stochastic model is proposed to describe the dynamics of CO2 emission with control inputs: clean technology, reforestation and carbon tax, under stochastic uncertainties.

CO2 Control In School Classrooms AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that overventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...

Classroom carbon dioxide concentration, school attendance ...

Background: We tested the hypothesis that classroom carbon dioxide (CO2 ) concentration is inversely related to child school attendance and educational attainment. Methods: Concentrations of CO2 were measured over a 35 day period in 60 naturally ventilated classrooms of primary school children in Scotland. Concentrations of CO2 were related to the class average annual attendance and ...

Carbon dioxide (CO2) demandcontrolled ventilation in ...

· Purpose To study the effects of a CO2 demandcontrolled ventilation system (variable flow) in computer classrooms on perceived air quality and sick building syndrome. Methods University students (27 % women) participated in a blinded study. Two classrooms had variable flow (mean ac/h); two others had constant ventilation flow (mean ac/h). After one week, ventilation conditions …

· The device was CO 2 controlled, using a realtime, selfcalibrating CO 2 sensor (Telair 6613 CO 2 module, GE Measurement Control, USA) to adjust the amount of outdoor air supplied, in order to achieve a target steadystate CO 2 concentration in the classroom. This CO 2 sensor was located at one of the walls of the classroom, at approximately m from the floor, where possible …

[PDF] Identifying CostEffective CO2 Control Levels for ...

Studies of CO2 capture and storage (CCS) from coalfired power plants typically assume a capture efficiency near 90%, although the basis for a particular choice usually is not discussed. Nor do studies systematically explore a range of CO2 capture efficiencies to identify the most costeffective levels of CO2 control and the key factors that affect such levels.

Sick Classrooms Caused by Rising CO2 Levels

· Sick Classrooms Caused by Rising CO2 Levels. “Exposure to CO2 can result in drowsiness, eye irritation, and inability to concentrate. If a ventilation system provides inadequate freshair intake, levels of CO2 in the classroom can rise dramatically during the course of a classroom session.”. Brian W. Smith.

Control of CO2 in a naturally ventilated classroom ...

The teaching staff and pupils control the ventilation into the classrooms by thermal comfort rather than air quality. Abstract The ventilation performance of a naturally ventilated classroom was investigated to monitor the CO 2 levels and compare compliance with new guidelines. Measurements of CO 2 levels were taken for 1 week during the heating season while different ventilation modes were ...
