Suggested CO Control Sequence Of Operation

Sensor Placement: Sensors should be placed so that they can take a representative sample of CO 2 concentrations in each major occupied zone. Sensors can be placed in the space using similar location criteria to thermostats. An addition consideration is that the sensor should not be in a location where people might regularly breath directly into

NDIR Carbon Dioxide Sensor for HVAC Application Cubic ...

CO2 sensor application in the HVAC system A ventilation system is a mechanical structure that is mainly used to control indoor(commonly homes and offices) air quality. Its main function is to introduce a constant supply of fresh air, usually from the outside. Managing the fresh air brought into the house and polluted air removed outside to realize proper ventilation rates is the key point. (24) of people are quite normal and maximum concentration CO2 …

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. Safety: Wherever compressed CO2 is stored or created, CO2 safety alarms should be mounted 18 inches (45cm) off the floor. Because carbon dioxide is heavier than air, it will first pool at floor level, then fill the enclosed space. The rate at which the space is filled is dependent on the size of the leak, but in a small room CO2 levels can …
