1. Monitoring Objectives
Commercial spaces, such as office buildings, exhibition halls, airports, hotels, shopping centers, stores, stadiums, clubs, schools, and other public venues, require air quality monitoring. The primary purposes of air quality measurement in public spaces include:
Environmental Experience: Improve and maintain indoor air quality to enhance human comfort.
Energy Efficiency and Cost Reduction: Support HVAC systems to provide on-demand ventilation, lowering energy consumption.
Health and Safety: Monitor, improve, and assess indoor environments to ensure the health and safety of occupants.
Compliance with Green Building Standards: Provide long-term monitoring data to meet certifications such as WELL, LEED, RESET, etc.
2. Key Monitoring Indicators
CO2: Monitor ventilation in high-traffic areas.
PM2.5 / PM10: Measure particulate matter concentrations.
TVOC / HCHO: Detect pollutants released from building materials, furniture, and cleaning agents.
Temperature and Humidity: Indicators of human comfort that influence HVAC adjustments.
CO / O3: Monitor harmful gases such as carbon monoxide and ozone (depending on the environment).
AQI: Evaluate overall air quality, in line with national standards.
3. Monitoring Equipment and Deployment Methods
Duct-Type Air Quality Monitors (e.g., Tongdy PMD)
Installation: Installed in HVAC ducts to monitor air quality and pollutants.
Features:
Covers large spaces (e.g., entire floors or large areas), reducing the need for multiple devices.
Discreet installation.
Real-time integration with HVAC or fresh air systems allows data to be uploaded to servers and apps.
Wall-Mounted Indoor Air Quality Monitors (e.g., Tongdy PGX, EM21, MSD)
Installation: Active areas such as lounges, conference rooms, gyms, or other indoor spaces.
Features:
Multiple device options.
Integration with cloud servers or BMS systems.
Visual display with app access for real-time data, historical analysis, and warnings.
Outdoor Air Quality Monitors (e.g., Tongdy TF9)
Installation: Suitable for factories, tunnels, construction sites, and outdoor environments. Can be installed on the ground, utility poles, building facades, or rooftops.
Features:
Weatherproof design (IP53 rating).
High-precision commercial-grade sensors for accurate measurements.
Solar-powered for continuous monitoring.
Data can be uploaded via 4G, Ethernet, or Wi-Fi to cloud servers, which are accessible from computers or mobile devices.
4. System Integration Solutions
Supporting Platforms: BMS system, HVAC system, cloud data platforms, and on-site displays or monitors.
Communication Interfaces:RS485,Wi-Fi,Ethernet, 4G,LoRaWAN.
Communication Protocols: MQTT,Modbus RTU/TCP,BACnet,HTTP,Tuya,etc.
Functions:
Multiple devices are connected to the cloud or local servers.
Real-time data for automated control and analysis, leading to improvement plans and evaluations.
Historical data exportable in formats like Excel/PDF for reporting, analysis, and ESG compliance.
