A clogged VAV (variable air quantity) coil in an HVAC system can limit airflow, lowering the system’s effectivity and cooling or heating capability. Cleansing the coil can restore optimum airflow and enhance system efficiency.
Cleansing a clogged VAV coil usually entails the next steps:
When working with HVAC methods, you will need to be capable to examine IWG to CFM to make sure that the system is working effectively. IWG stands for inches of water gauge, and it’s a measure of the strain of the air within the system. CFM stands for cubic ft per minute, and it’s a measure of the amount of air that’s flowing by the system.
With a view to examine IWG to CFM, you have to to make use of a conversion issue. The conversion issue is 1 IWG = 0.00231 CFM. Which means for each 1 inch of water gauge, there’s 0.00231 cubic ft of air flowing by the system.
