Air quality managementIndoor CO₂ Concentration Management

A CO₂ absorbent–based smart control system that maintains target indoor CO₂ levels, reducing unnecessary ventilation energy consumption while improving indoor air quality (IAQ).

  • Real-time CO₂ Monitoring and Control

    Maintains indoor CO₂ concentration through absorbent cartridge–based control.

  • Energy Savings

    Minimizes heating and cooling losses caused by excessive ventilation.

  • Safe and Low-Noise Design

    Built with low-resistance air pathways and safe materials for quiet operation.

Why Indoor CO₂ Control Matters

Problems with Conventional Air Quality Management

  • Rapid CO₂ buildup in crowded spaces leads to drowsiness and reduced concentration.
  • Over-ventilation wastes heating and cooling energy.
  • Fixed ventilation settings fail to adapt to real-time occupancy and CO₂ fluctuations.

Green City Solution’s Approach

  • Suppresses sudden CO₂ spikes using absorbent modules.
  • Maintains optimal levels via PID control, minimizing unnecessary ventilation.
  • Integrates with BEMS and HVAC systems for zone-specific smart operation.

Core Features

  • Modular CO₂ Absorbent Units

    Cartridge-type absorbent modules applicable to classrooms, offices, and meeting rooms.

  • Smart Control

    CO₂/humidity sensors + PID controller maintain target CO₂ level (e.g., 500 ppm).

  • Building Integration

    BBACnet/Modbus communication for BEMS and HVAC system integration.

  • Easy Cartridge Replacement

    Convenient operation through replaceable absorbent cartridges.

  • Data Dashboard

    Visualizes concentration, absorbent usage, and estimated energy savings.

  • Low-Power Operation

    Compact design with low-power fans and sensors minimizes energy consumption.
