Evaluation of design ventilation requirements for enclosed ...

Jul 01, 2000· Abstract. This paper proposes a new design approach to determine the ventilation requirements for enclosed parking garages. The design approach accounts for various factors that affect the indoor air quality within a parking facility, including the average CO emission rate, the average travel time, the number of cars, and the acceptable CO level within the parking garage.

Energy Efficient HVAC Controls | Outside Air Optimization

When occupancy is high, 75F will modulate the outside air damper to ventilate with fresh air until healthy indoor air quality is achieved. Other 75F IAQ sensors, such as CO and NO 2 sensors, can be added to this sequence for spaces like parking garages or other applications. The 75F outside air sequence includes a control point to activate an ...

Carbon Monoxide and Parking Garage Ventilation Systems

The ventilation system for the phase 1 garage consists of an exhaust fan that operates at a constant volume 24/7. The phase 2 garage has a more complex system that consists of an exhaust fan with a variable speed drive (VFD) connected to CO sensors throughout the space. This fan is set to run 24/7, but the speed varies based on the level of CO.

Where should I place a carbon monoxide detector? | Indoor ...

Jul 15, 2020· Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flameproducing appliance. Keep the detector out of the way of ...

The first thing that comes to mind when a car is started in a garage is carbon monoxide (CO). Today''s cars with catalysis emit higher levels of CO₂, which is why we strongly recommend multiple sensors. If a CO sensor is controlling the air flow, you will find that the exchange rate is far too low. When the parking …

Jan 08, 2019· The most common gas sensors used in HVAC systems are oxygen (O 2) and carbon dioxide (CO 2) sensors. Ambient air is comprised of roughly 21% O 2 and just % CO 2, but a lack of indoor air circulation can dramatically skew the gas composition towards O 2 depletion and CO 2 enrichment. Indoor air quality (IAQ) is a critical factor for our ...
