CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation 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 ...

It is very important to design CO2 supply and control systems so that the cross section of the plumbing line never (expands and subsequently) restricts. This will invariably result in dry ice blockage. Due to the lower costs to capture and compress CO 2, it is generally commercially cheaper and for that reason can be a preferable coolant.

· 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 ...
computer model that is available for the design of CO2 control in intensive aquaculture operations and cover some model simulation results. Recirculating Aquaculture Systems Short Course CO2 PRODUCTION • Molar basis –1 moel of CO 2 is produced for every 1 mole O2 consumed • Mass basis – g of CO2 is produced for every 1 g O2 consumed Production – on a molar basis 1 mole of carbon ...
Climate computer. Precise climate control. The DOL 53X climate computer can be used in all types of poultry houses. It regulates and monitors the house climate, and can regulate temperature, humidity, ventilation, heating, cooling, humidification, and CO 2. The touch screen of the climate and production computer is easily operated.
· 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 fresh-air intake, levels of CO2 in the classroom can rise dramatically during the course of a classroom session.”. Brian W. Smith.
· Net Control 2 Classroom: Includes more than 150 various teaching, communicative, controlling and monitoring features combined in a user-friendly and easy-to-use user interface. It was specially designed for use in educational environment, to simplify the teaching process and to make it more effective. Supports more than 9 languages, used in ...

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 ...
· To study the effects of a CO(2) demand-controlled ventilation system (variable flow) in computer classrooms on perceived air quality and sick building syndrome. Log In Sign Up Carbon dioxide (CO2) demand-controlled ventilation in university computer classrooms and possible effects on headache, fatigue and perceived indoor environment: an intervention study.
Net Control. The final classroom management software on this list is Net Control and it offers plenty of exclusive features for efficient class management. Presentation becomes quite easy with Net Control as teachers can broadcast their screens to students and can also turn on voice and add images. Teachers can monitor students in real-time by viewing their computers. Key features of Net ...
High CO2 levels in school classrooms continue to be a concern. As a result we reviewed the mass-balance model of ventilation. We identified several factors by fitting the model to the data.
• Computer • Extension cables • Adhesive tape • Digital Camera . Installing the CO 2 sensor 1. Place the CO 2 sensor at the back of the classroom in an elevated place in order not to distract the pupils during normal class hours. 2. Fasten the CO 2 sensor onto the stand with the clamp and, if necessary, secure this with adhesive tape. Be sure that the there is free air circulation ...
2 Control In School Classrooms 1 of 3 CO 2 Control In School Classrooms Why Consider CO2 Control There are four primary reasons to consider using CO 2 sensors in school classrooms. 1. Student Health Considerations CO 2 monitoring can ensure that acceptable levels of ventilation for the health and welfare of students and teachers is maintained at all times. • Are Codes & Standards Being …
classroom example. Therefore, the desired differential between indoor and outdoor CO2 concentrations remained constant, too, regardless of how many people actually occupied the zone (Figure 1). By controlling to this constant differential, Cs – Co, CO2-based demand-controlled ventilation maintains the same per-person ventilation rate (Vo) to
