HVAC (Heating, Ventilation, and Air Conditioning)

HVAC (Heating, Ventilation, and Air Conditioning) refers to systems that manage indoor temperature, humidity, ventilation, and air quality. As buildings become more airtight and energy efficient, there is a growing need to perform air conditioning and ventilation efficiently while maintaining indoor air quality.

CO₂ concentration can be used as an indicator for understanding occupancy and ventilation conditions. By measuring CO₂ concentration and integrating it with air conditioning and ventilation systems, ventilation can be controlled to provide the necessary amount of fresh air where it is needed.

In HVAC, balancing comfort and energy savings is important. Excessive ventilation can increase air conditioning energy consumption, while insufficient ventilation can lead to poor indoor air quality.
Using CO₂ sensing enables the following types of control.

• Occupancy-based ventilation control
• Understanding ventilation conditions in each space
• Demand Controlled Ventilation (DCV)
• Optimization of HVAC energy consumption
• Integration with building management systems

In DCV based on CO₂ concentration, ventilation rate can be adjusted according to occupancy and ventilation conditions in each space. This helps ensure the required amount of ventilation while reducing air conditioning energy losses caused by excessive ventilation.

Air Conditioning Equipment

Indoor CO₂ concentration can be measured and used for air conditioning and ventilation control. Ventilation can be controlled as needed while maintaining comfort.

Ventilation Systems

By adjusting ventilation volume according to CO₂ concentration, indoor air quality can be maintained while reducing excessive ventilation.

Building Automation

Can be used to integrate air quality monitoring and air conditioning control in office buildings, commercial facilities, schools, public facilities, and more.

Duct Measurement

CO₂ concentration can be measured in air conditioning ducts or ventilation paths and used to control the overall system.

Smart Homes

By understanding indoor air quality and connecting with ventilation systems and air conditioning equipment, it helps create comfortable and efficient living environments.
