can co2 control sensor for classroom recess

Demand-Controlled Ventilation (DCV) - SVACH

DCV sensors most commonly measure carbon dioxide (CO2) and/or relative humidity. Typically, the ventilation system withdraws air from “damp or humid” rooms (bathrooms, kitchens, laundry, work areas) and supplies air to “dry” rooms (offices, living rooms, bedrooms). Occupancy sensors, like those used for lighting systems, may also control ventilation systems. Occupancy sensors are a ...

Why Monitor CO2 in Classrooms? -

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a high-level of indoor air quality, is to monitor Carbon Dioxide (CO2) levels within the classroom. Every time you exhale, you release CO2 into the air. Therefore, the CO2 level lets you determine if the room is being properly ventilated with fresh outside air; thereby, helping you gauge the quality ...

Indoor CO2 sensors for COVID-19 risk mitigation: Current ...

2021-05-18· 2021-05-18· Can we reduce ventilation if CO 2 levels can be maintained below 1000 ppm? In some facilities, CO 2 monitoring is used to estimate occupancy, which in turn is used to reduce outdoor air intake if/when occupancy is low. This is known as demand control ventilation and in non-pandemic conditions can be a useful energy-saving feature. However ...

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 ...

2012-10-24· 2012-10-24· Let us take, for example, a classroom, where close to 40 persons or more may gather at a time, each releasing between 20 and 25 liters of carbon dioxide per hour through respiration alone; this usually winds up with poor air quality being the end result which can lead to the “sick building syndrome” phenomenon. The introduction of carbon dioxide sensors in classrooms …
