Applications of CO, CO2 and Temperaturehumidity Sensors ...

Jul 11, 2018· The number of sensors (referring to number of fans), and typical sensing point (the default detection radius of the sensor is 5m) are determined by the controlled range of each draught fan. To keep the indoor air quality in underground parking garages at a comfortable level, CO 2, temperature and humidity should also be take into consideration.

Fire protection in parking garages

in parking garages because the exhaust emissions caused too many false alarms. Pointtype heat detectors were often used which triggered an alarm when there was a significant temperature increase, or a maximum temperature was reached (typically 60 °C). In large parking garages, linear heat detectors (sensor cables or

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.

Designing a JetVent Parking Garage Ventilation System

CO Sensor A Carbon Monoxide sensor should be placed so no part of the garage is more than 50'' from a sampling point. A 100'' diameter circle around a CO sensor will show the coverage area, and typically equates to one CO sensor per fan. Additional CO sensors should be placed to provide additional coverage in areas where people congregate. NO 2 ...
