Use of Air-System Components as Orifice Meters for Airflow Control Systems

摘要

This paper explains the methodology and benefits of using existing components of an air-handling unit (AHU), such as heat exchangers, heaters, and other apparatuses, as effective orifice airflow meters. These quasiorifice meters can be used in lieu of airflow monitoring stations and standard orifice meters to help monitor and control many types of HVAC systems.
