DUCT MOUNT UNIT Air Quality Sensors

  One of the greatest concerns of todays facility managers is the health and safety of the occupants of their building, and Indoor Air Quality is a key factor. BAPIs Air Quality Sensors allow for continuous monitoring to help control the air quality of a facility. The sensors can be placed in individual rooms and in air ducts and can send data directly to the building management system. Information from the sensors can also be recorded over time and easily imported into standard spreadsheet packages for analysis. This type of on-line monitoring offers a number of important benefits including energy savings through demand-based control of outside air intake, optimizing the air quality of the facility, identifying potential air quality problems in the early stages and demonstrating your commitment to tenant satisfaction.
   The BAPI Duct Mount Air Quality Sensor utilizes a unique oxidizing element that varies in resistance with respect to the contaminant gases it contacts. The sensor is non-specific to any one gas. Instead, the output signal corrosponds to the combined concentration of over 30 contaminant gases typically found in indoor environments (see the chart on the ). This provides a much more accurate representation of the actual air quality than a CO2 Sensor which senses only CO2 and not the other contaminants that could be present.
   The principle purpose of the Air Quality Sensor is to control the amount of outside air introduced by a ventilation plant and thereby reduce energy consumption by eliminating the introduction of excess outside air into the system during periods of little or no occupancy. Besides the savings from demand-based control of outside air intake, on-line sensing also assures air quality throughout the facility and can help identify potential problem areas (such as contimants from carpets, equipment, furnishings or chemicals) before they reach a critical stage. The facility manager can also analyze the recorded data from the sensors and adjust building processes for optimum air quality and occupant comfort.
