Abstract
A method of measuring a Heating, Ventilating Air Conditioning (HVAC) system airflow across an evaporator coil or heat exchanger comprising drilling a single hole in a near side of a plenum, a duct, or a box and inserting an anemometer probe in the single hole, and taking at least one airflow measurement selected from the group consisting of: a near side airflow, a centerline airflow, and a far side airflow. Calculating an average HVAC system airflow based on the at least one airflow measurement. A second method determines which side of the plenum, duct, or box has higher airflow based the near side airflow, the centerline airflow, and the far side airflow and measures more than 50% of the airflow measurements on the higher airflow side and calculates an average HVAC system airflow based on a sum of the airflow measurements divided by the total number of airflow measurements.
