  • Methods and apparatuses for controlling air to a building
    Patent number: 7891573
    Abstract: HVAC systems, including various HVAC system components, and methods for manufacturing the same are disclosed for controlling airflow into a building. Embodiments of the HVAC systems include apparatuses for controlling the volumetric airflow moving through at least one HVAC system component using a measurement device, for example an airflow detector, a regulator, for example a damper or blower, and a controller, where the controller receives input from the measurement device, manipulates the input with a control algorithm, and sends output commands to the regulator. Further embodiments include apparatuses and methods for development of the control algorithm by testing a similar HVAC system component, measuring the actual volumetric airflow through the HVAC system component, and comparing the actual volumetric airflow with the airflow measured by the measurement device. Still further embodiment include forming a plurality of similar HVAC components that each control airflow without requiring further testing.
