ALC – Hardware
Humans respirate Volatile Organic Compounds (VOCs) as well as CO2. This new
BAPI sensor is able to measure these VOCs, therefore it is as good an indicator of
space occupancy as a CO2 sensor.
The BAPI Sensor is different from other VOC sensors because it has been
optimized for Demand Controlled Ventilation (DCV). Using a calibration algorithm,
the sensor value is converted to an output with a high correlation to a CO2 level
This lets you use ASHRAE’s occupancy-based VRP schedule to ventilate.
(More info on this correlated output is available on the BAPI control parts website at http://www.bapihvac.com)
Besides from respiration, the sensor picks up VOCs from other sources such as
building materials, perfumes, colognes and furniture off gassing. Using this sensor
to ventilate is a way of acheiving true indoor air quality and not just CO2 dilution.
The unit is available as a VOC sensor alone or as a combination temperature
and humidity sensor. The optional display alternates between the measured
values and is field adjustable between °F or °C. An optional three color LED
indicates “VOC Level” of Good, Fair or Poor.
