According to a group of HVAC specialists in the New York metro area, many people who plan on installing exhaust fans may not know the right way to determine airflow. There are countless specifications that state exactly how much air a particular process needs. In order to find out if a certain unit is going to be in spec, technicians will have to be able to calculate how much air a group of units can pass.
Three different methods are used to measure airflow. Judging by a recent publication put out by area specialists, the air balancing hood technique is best for those who have the grill of their HVAC exhaust fan flat up against the ceiling or a wall. Technicians can easily slip a hood over this grill to figure out how much air they have going through the area at any given time.
Traverse measurements might be a better choice for those who have to deal with a more complicated installation scenario. This involves drilling holes at strategic points along some ductwork and then using an anemometer to measure exactly how much air the HVAC exhaust fan can move. Those who have access to the original equipment manufacturer’s performance tables can forgo either of these methods and instead opt for a plot fan airflow test. Regardless of which technique a team decides to go with, there’s a good chance they’ll need to work with professionals in order to get accurate results.
