As people return to indoor spaces, a major concern is air quality. GreenMediaHD (GMHD) has developed a system that can be retrofit to an existing air handler unit (AHU) to filter out pollutants and contaminants as the air passes through them. Called the GreenMediaHD Indoor Air Quality System (IAQP), it uses a negative ion injection technique to improve air quality by reducing possible Volatile Organic Compound (VOC) contamination and minimizing the risk of a health hazard from airborne virus and bacteria in the duct system.
A bipolar ionization system is added to the AHU. This system creates a plasma curtain of billions of negative ions to de-activate any potential organic compounds. When high enough concentrations of negative ions come in contact with harmful pathogens such as a virus, bacteria, or mold, they steal away hydrogen molecules from the pathogens. Without hydrogen, the pathogens are left without any source of energy and they die.
Contemporary Controls plays a key role in this system. Real time air quality data is collected by a series of Wi-Fi multi sensor devices (Temperature, Humidity, CO2, VOC, Fine Dust) and sent to a GMHD gateway with a BACnet/IP server. The gateway is routed into the existing BACnet architecture of the building using our BASrouter model BASRT-B that routes messages between BACnet/IP, BACnet Ethernet and BACnet MS/TP networks. The data from the BACnet IP Server can be accessed via BACnet MS/TP using the BASrouter. It also supports 5 BBMD entries that allows the Air Quality System, if required, to integrate into the subnets of the existing BACnet topology in the building.
For maintenance, new setups and upgrades, the GreenMediaHD Air Quality System can be accessed locally by its web page, or remotely utilizing a Contemporary Controls EIGR-V Skorpion Gigabit IP Router with VPN capability. Both wired and cellular models are available. This allows the support team to remotely make the necessary changes and setups in the AP routers where the sensors are connected, to improve and expand the system and correct any issues.
