5 ton system pressure drop questions
Once again, I have read lots of information and what we are being told and what exists does not fit when it comes to calculating ESP. As, I have mentioned before I have a 5 ton unit and the coil itself is .498 pressure drop and most other 5 ton coils are @ 0.5 and that is what all these furnaces are rated to handle @ 2000 CFM. That leaves no room for ductwork, grilles and even filters to be installed and keep the system balanced within this guideline or maintain the SEER rating of the system. What am I not understanding as I see everything below 5 ton units the coils pressure drops are much lower allowing room for all other ESP to be factored in. Can someone please explain the secret here if there is one?
