concentration (Co) of carbon dioxide seldom varies by more than 100 ppm from the nominal value.* Because of this and in lieu of installing an outdoor CO2 sensor, most designers use either a one-time reading of the outdoor CO2 concentration at the building site or a conservative value from historical readings. This simplifies control,

2012-03-16· Purpose To study the effects of a CO2 demand-controlled 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 …
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 ...

Clarkson Controls are Raising Standards in the Classroom for ventilation and C0 2 control to meet new BB101 regulations. The government is getting tough on air quality in the classroom. Under the 2017 BB101 Guidelines maximum CO 2 limits have been reduced significantly and flow rates have been established to include science labs, halls and gyms to ensure children experience a healthy indoor ...
Indoor Air Quality in Classrooms and COVID19. April 12, 2021. The effect of poor indoor air quality in classrooms has been known for years. Chronic illnesses, reduced cognitive abilities, sleepiness, and increased absenteeism have all been attributed to poor IAQ - specifically elevated CO2 levels. What's more concerning today is the effect ...

The carbon dioxide -based control identifies when people enter the premises and enhances the efficiency of ventilation almost steplessly. This way, ventilation is not too efficient when there are only a few people present in the classroom but the same room can also be used by large groups. Humidity-based control is the best method to control the efficiency of ventilation in sports facilities ...
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.
