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.
Carbon dioxide is one of the most plentiful by products of the combustion process used by automobiles, trucks and fuel-fired appliances. For properly operated and maintained equipment CO2 will be produced in quantities 100 times or greater any other combustion byproduct considered harmful, including carbon monoxide, hexane, nitric oxide or nitrogen dioxide. This article shows a breakdown of the by-products of combustion by volume (in ppm) for an automobile at idle.
A simple tool made by a Santa Barbara Company for measuring indoor air quality and ventilation in buildings is now being used to quickly identify if shipping containers are carrying a hidden human cargo.
Ventilation is an important part of maintaining a comfortable, healthy, productive environment for students and faculty. Improper ventilation can have a negative impact on occupant health and performance, increase the risk from litigation and/or waste energy. Numerous organizations now require and/or recommend CO2-based ventilation control in different commercial HVAC applications. The following article give examples and links to these codes, standards, and reports. Also, some utility companies offer rebates to building owners for installing CO2 sensors. Other utility may offer rebates based on the energy savings potential, so check with your local power provider.
Discusses common CO2 wiring issues, such as interfacing with a Honeywell economizer control and multiple sensors with a single air handler.
Answers to common questions regarding Demand Control Ventilation. Examples: How many sensors are required in a typical installation? What is ventilation control? How do you calibrate the sensor?
Ventilation control using CO2 is one of the fastest growing building control strategies being implemented in new and retrofit building projects today. This approach can provide better control of building ventilation, help assure tenant comfort and reduce complaints while reduce operating costs related to ventilation. Outlined in this article are answers to 12 of the most common questions that a building owner may ask about using CO2 to control ventilation in buildings.
Overcooling and overheating a building wastes money. Both of these conditions occur when too much or not enough outside air is brought in. In either case, proper CO2-based ventilation control can eliminate this problem by bringing in the right amount of outside air to maintain the indoor environment, saving energy and reducing emissions.
