CO2 sensors in HVAC applications

co2 sensors

The demand for CO2 sensors from IBC customers is on the rise due to the implementation Covid-19 strategies, with occupant health and comfort top of mind. IBC carry a wide range of CO2 transmitters with many, including Industrie Technik, which are in stock at IBC’s warehouse. Browse all sensors or contact an IBC rep who can find the right sensor for your requirements. Contact/order from IBC here or explore our in stock CO2 range here.

Industrie Technik CO2 sensor

The CO2concentration is measured using infrared light, a technique that measures the absorption in gases. It has a reference measuring system that compensates values in relation to changes in light intensity. This technique has many advantages:
• Very high accuracy
• Exact identification of the detected gas
• Low risk of contamination
• Short response time
• Excellent long-term stability

Indoor CO2 measurement using sensors that are easy to install at a low cost appears promising for mass monitoring of indoor aerosol transmission risk for Covid-19 and other respiratory diseases. Using a Co2 sensor to measure indoor air quality, along with increasing airflow through buildings, is a a key tool in any Covid-19 strategy. The risks to occupant health in buildings old and new cannot be properly assessed without measuring it. It may not remove the virus completely but it is a recommended and effective tool in reducing the spread, especially in poorly-ventilated indoor spaces where people gather

What level is safe?

CO2 measured indoors is a key indicator in monitoring the amount of fresh air the room has because occupants breath CO2 out. Smart Buildings outlines CO2 level targets:

“Different CO2 level targets should be set based on the environment and activity type, since infection risk level has been shown to vary by a factor of 100 or more depending on the situation and activity type. Factors such as the number of infected people in a region, and measures such as mask-wearing or air filtration may reduce presence of the airborne virus without reducing CO2 levels. Certain activities increase virus emission far more than CO2 levels, such as talking, singing and shouting. Both CO2 and the virus are diluted by ventilation with outdoor air. They are not, however removed by recirculating the air, for example through heat exchangers.”
