Im am trying to figureout how to calculate savings using a VFD -
Variable Frequincy(Speed) Drive
Direct energy savings easy
I am trying to Calculate the savings in AIR FLOW/+/Air temp-differerance
Not exausting 75'F air outside at say 10,000 CFM - And not bringing in 30'F Air in the winter at the same CFM's
I am not looking for a direct answer I am am looking for equations/examples? such as. Cost to heat 1 CF of Air per Degree F , Without going into too much detail I can use some assumptions (efficency of heating sorce etc.)
