Airflow Control Options
Mfg: Greenheck Published: 2004 Version: MUA-TSU 80/20 & W SP Rev. 2 8 pages
A damper with a modulating actuator is controlled by output from a photohelic gauge that compares the indoor and outdoor air pressures. As exhaust air volumes vary, the outside air volumes are adjusted to maintain the desired building pressure. A slight positive pressure is a normal setting. Outside air and recirculated air volumes combine to provide the supply air. Add to My Library
Air Flow Measuring Control Damper
Mfg: Greenheck Published: 2006 Version: IAQ Rev 1 April 6 pages
Airflow measurement accuracy is dependent on the density of the air being measured and in turn air density is a function of temperature. The IAQ-42 monitors the dry-bulb temperature of the air passing through it and corrects the air density used to calculate the airflow rate. Airflow measuring devices that do not compensate for changes in air density must assume a “standard” density to calculate an airflow rate. Add to My Library
