Demand Control Ventilation (DCV) Application


Demand controlled ventilation (DCV) could achieve an automatic adjustment of ventilation equipment according to occupant choice.


A: With real time indoor CO2 concentration monitoring based on CO2 sensor measurement, the system could adjust the indoor ventilation system to creat a comfortable environment and make sure your system is running as efficiently as possible, so as to achieve energy-saving effects.

B:  Besides CO2 sensor, real-time monitoring of particulate matter concentration in the HVAC system helps air purification system intelligently start the self-cleaning mode to purify the enclosed space air quality effectively.


1. According to the indoor air indicators by the real-time monitoring data and setting the alarm reminder of pollutants which exceeding the standard to control  the working mode of the HVAC system automatically and achieve energy saving and environmental protection.

2. With real-time monitoring of indoor and outdoor particulate matter concentration, it can assist the HVAC system to intelligently filter PM2.5 in the air, can also be used as a reference value for filter replacement.

3. With real-time monitoring of indoor CO2 concentration or HCHO concentration, it can assist the HVAC system to start external circulation automatically and create a natural oxygen bar for users.
