Leakages Calculation - Pharmaceutical HVAC

· Leakage control. Creating a differential pressure difference is achieved by causing air movement through room leakages openings. This may be through wall openings or gaps around doors. We will not consider duct or pipe penetrations, cracks, etc, as these should be sealed according to best practices of airtight construction. Leakages calculation is the first step we should know to calculate ...

Why measure CO2 in HVAC applications? |

Instead of constantly providing fresh air, buildings used carbon dioxide sensors to “sense” when the buildings were occupied. 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.
