Using the BAPI VOC Sensor D27

This paper will prove that the BAPI’s Volatile Organic Compound (VOC) sensor is an accurate and reliable way of incorporating Demand-Controlled Ventilation (DCV) into a building’s HVAC strategy. It will also show that the VOC sensor is as good an indicator of space occupancy as a CO 2 sensor while also mea-suring other air contaminants which affect human comfort and health. The paper will also …

VOC Sensor - Alphasense - PDF Catalogs | Technical …

VOC Sensor p-type Metal Oxide This sensor is a broadband total VOC detector. When the cost of a PID is not justifiable, this sensor will detect VOCs with 10-50 ppb limit of detection, depending on the VOC. Unlike common n-type sensors, this metal oxide sensor has a large dynamic range, repeatable response, low humidity response and resistance increases in the presence of most VOCs. The change in …

Using the BAPI VOC Sensor for Demand Controlled Ventilation ...

The VOC sensor has slightly higher readings than the CO2 sensor during breakfast and the morning breaks because the VOCs from the food are added to the VOCs generated by the people. This is also seen at lunch as cooking of the sausage pizza generated lots of VOCs which are added to the VOCs from the students and staff. Additional fresh air is brought in to dilute the VOCs during the lunch period. …
