Hi all,
I am not very knowledgeable in HVAC and have a basic questions.
If I have an open loop air system where the unit pulls air from the ambient, goes through filters, cooling coils, air blower, then through some ductwork. The cfm needs to be about 2000 cfm at the end of the ductwork and the air blower is sized accordingly.
My questions is that with the same system, if I connect the end of the ductwork back to the intake of the unit to form a closed loop system. Still requiring 2000 cfm at the same point of measurement in the ductwork. Would this lead to less requirement for the air blower?
If so, what is the math/thorem behind it?
Appreciate any feedback
