Guide to measuring ventilation rates in schools

2020-08-28· **Note: Carbon dioxide sensors have become better and less expensive in the recent years. For the uses described here, it is useful to have a sensor that can give back the raw data to the users. It is also useful to have a sensor with a display that shows realtime CO 2 levels and a sensor that reports measurements at least once a minute. 3

Guidance for Schools - REHVA

in the classroom, away from fresh air inlets ( open windows). In times of the pandemic, we suggest to temporarily change the default settings of the traffic light indicator (orange light up to 800 ppm and red light up to 1000 ppm) in order to promote as much ventilation as possible. • Check operating hours of mechanical ventilation systems. Switch ventilation to nominal speed at least 2 ...

"Ventilation Control Options" - Modular Building Institute

CO2 sensors can open the ventilation device and turn on the blower motor independent of the heating and cooling function in most HVAC units with the addition of some optional relays. The objective of using CO2 sensors is to limit ventilation (energy use) to the times when the room requires it. If only one occupant is in the room, chances are no ventilation will be required. Add 20-30 more ...

CO2 Occupancy Sensing Switch Instruction / Installation Guide

The A/CO2 transmitters monitor carbon dioxide (CO2) levels in industrial and living environments from 0 to 5,000 ppm. The concentration of CO2 is a good indication of the indoor air quality (IAQ). All units come with both a 4-20 mA and 0-10 VDC analog output as well as a relay output with an adjustable setpoint and deadband (Hysteresis). Units come standard with LCD displays as well.

Easy solutions for indoor air problems at schools - Vallox

Carbon dioxide -based control is an excellent means to control ventilation automatically based on the need in premises where the number of occupants varies. 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 ...

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,

Carbon Dioxide (CO HVAC Basics - Honeywell

Do not confuse carbon dioxide (CO2) with carbon monoxide (CO), a highly toxic gas that is also a byproduct of combustion in furnaces, fireplaces and automobiles. Carbon monoxide (CO) can be harmful, even at very low levels (25 to 50 ppm). CO2 as an IAQ Indicator Claims that CO2 sensors are indoor air quality (IAQ) sensors are inaccurate. CO2 levels are one piece of the undefined indoor air ...

Indoor Environmental Quality: Building Ventilation | NIOSH ...

Carbon dioxide (CO 2) is a normal constituent of exhaled breath; thus, CO 2 will also increase during building occupancy. CO 2 levels are routinely collected in air quality studies because they can indicate whether a sufficient quantity of outdoor air is being introduced to an occupied space for acceptable odor control. The American National Standards Institute (ANSI) and ASHRAE have developed ...
