A clogged VAV (variable air quantity) coil in an HVAC system can prohibit airflow, decreasing 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 sometimes includes the next steps:
When working with HVAC techniques, it is very important be capable of 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 stress of the air within the system. CFM stands for cubic toes per minute, and it’s a measure of the amount of air that’s flowing by way of the system.
With the intention to examine IWG to CFM, you will have 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 may be 0.00231 cubic toes of air flowing by way of the system.
