Desiccant rotors international offers eco fresh co2 sensors. The ecofresh carbon dioxide [co2] sensors and controllers are designed for demand controlled ventilation, dcv in buildings. This approach, using co2 as an indicator of occupancy, allows ventilation based on actual occupancy while still maintaining ashrae recommended per-person ventilation rates.
The detector displays the parts per million [ppm] or co2 in the air and controls the opening and closing of a set of relay contacts that can be used to actuate fans to bring in fresh air in order to reduce the co2 level in this manner. Fresh air may be introduced in a sufficient volume to maintain a healthy breathing environment while keeping energy costs to a minimum. Over-ventilation of buildings can be reduced, energy can be saved and air quality can be optimized.
The ecofresh carbon dioxide [co2] detector mode sensor, is applicable to any situation in which the amount of co2 is used to indicate the breathing quality of the surrounding air.
