2021-05-18· Increase fresh air supply via the HVAC system; Keep ventilation system fans running during occupied periods, after hours, and on weekends; Install local exhaust, although increasing exhaust is not as effective as increasing fresh air supply. There may be some cases in which it is not possible to increase ventilation or reduce occupancy to maintain levels as desired. In such cases, it may be ...
Carbon dioxide or CO2 is a result of human metabolism. Moderate to high levels of CO2 can cause headaches and fatigue. To prevent or reduce high concentrations of carbon dioxide in a building or room, fresh air should be supplied to the room. NDIR is an industry term for “nondispersive infrared”, and is the most common and adequate type of sensor used to measure CO2.

One common CO2 monitor designed specifically for HVAC applications is the WiFi Indoor Air Quality Monitor. This device allows occupants to easily monitor and control CO2 levels specific for smart homes, classrooms, offices and commercial buildings.
The most common gas sensors used in HVAC systems to control the air quality are VO and carbon dioxide (CO2) sensors. Heating, ventilation, and air conditioning (HVAC) systems are broadly used worldwide to monitor and regulate the environmental conditions in every type of property and practically all vehicles on the road. Despite the apparent interrelation between these three primary functions ...
Commercial HVAC Control: As an alternative to wall mounting, commercial HVAC contractors will use duct-mounted CO2 transmitters. By sampling the air from the return air ducts, they are assured of getting the most consistent average air quality for each zone in the building.

Carbon dioxide sensors use either infrared light or a chemical process to measure levels of CO2. Sensors are also used to detect volatile organic compounds (VOCs). VOC sensors use a process called photoionization. Ionization is the changing of an atom’s charge. VOC sensors can ionize particles with ultraviolet light and measure electron levels. These measures allow them to detect toxic or ...
