Application Note Sensor Products for HVAC/R Duct and Room

The BAPI VOC sensor provides a CO2 equivalent ppm output so that Ashrae’s popular CO2based VRP procedure can be used for DCV; however, CO2 is not one of the VOCs that the sensor monitors. If your application needs to directly measure CO2, choose a CO2 sensor. Commissioning and Testing. BAPI’s VOC sensor is easily tested for proper operation.

Why measure CO2 in HVAC applications? |

When enough people enter a room, the CO2 level rises because of the CO2 from their exhaled breath, and the HVAC system begins to bring in the fresh air. When the people leave, the CO2 level drops because they are no longer breathing in the room, and the fresh air dampers close. Because most common uses for carbon dioxide in HVAC applications ...

HVAC Arduino Project Hub

The greenhouse has to work autonomously. We are responsible for the Heating Ventilation and Airconditioning, or shortly said the HVAC. We want to work ecoconsious. So we used the ground as a power source. This energy we call geothermic energy. It''s completely green and you don''t create any pollutants. We use the heat exchanger for this.
