Demand Control Ventilation Q&A - Telaire Application Note

Telaire Application Spotlight | Carbon Dioxide (CO2) Sensing in Railway Cars - Application Spotlight

Demand-based Outside Air Management is managed in railway cars in the exact same way it is managed in buildings - bring in only the necessary outside air to ventilate a space with variable occupancy, to minimize energy usage heating or cooling outside air. Known as Demand Controlled Ventilation, or DCV, the theory of measuring Carbon Dioxide (CO2) to monitor occupancy and air quality is now applied to train carriages.

ABCLogic™ Self Calibration Feature - Telaire Application Note

Use of CO2 to control ventilation is one of the fastest growing areas in building control. A primary reason for this growth is that the technology has now matured to the point where it is inexpensive, easy to use and reliable. Amphenol Advanced Sensors leads this trend with a number of unique innovations in its sensor design. This article explains a key patented feature of Amphenol Advanced Sensors’ technology called ABCLogic that enables CO2 sensors to automatically calibrate themselves once installed in the field. This feature eliminates one of the biggest concerns surrounding CO2 sensing… sensor drift and maintenance.
