First and Foremost, Co Sensor Calibration is a safety requirement when managing or owning buildings, Commercial, Residential, or Industrial.
Any Property which has a car park, without satisfactory natural ventilation, must ventilate the car park via mechanical means.
The Occupational Safety and Health Act, section 21, Ensures any Carbon monoxide-controlled ventilation system is regularly serviced, and records kept, ensuring CO levels do not exceed exposure standards. Carbon monoxide sensor test & calibration is an essential service.
Carbon Monoxide is a poisonous gas which is created when burning gasoline, wood, propane, charcoal or other fuel. It is a colourless, odorless, tasteless gas. Which is why you need specialized detectors and an extraction system.
In a nutshell, the gas sensor detects the gas (via a device which actually delipidates over time, hence the regular calibration) and sends a signal (4 – 20 Milliamp or 0- 10 volts DC) to a car park fan system controller.
The Controller will then start fans and if a Variable speed drive is detected, the controller will increase the speed of the fans subject to the amount of gas sensed and the set point of the controller
Typically, the Controller with have a start set point of around 8 ppm (parts per million) to start the fans, the fans will run for a minimum of 4 minutes. At 24 ppm the system and / or the fans should be 100%.
The sensor must detect zero ppm for at least 4 minutes, and the system has run for a minimum of 7 minutes, before the fans are allowed to deactivate.
An Alarm for high Co Concertation will be Annunciated at 35 ppm after 1 minute
The VSW is used primarily to conserve energy, it creates a “soft start scenario for the fans reducing the current draw as compared to D.O.L (Direct on Line)
D.O.L will draw around three times the nominal run current at start up.
The VSD means less current draw and less wear and tear on the mechanical component of the fan.
It also means the fan may not have to reach 100% before all the Carbon Monoxide is ventilated out of the car park and the sensor returns to Zero.
This provide an Energy saving also.
