Thanks Yorkman. I hadn't seen that article before. I just found a couple on the ASHRAE site that weren't very illustrative on the areas I had questions on. I downloaded the Trane whitepages on this though and they look to contain some good info. I'll repost here if there's anything left that...
Be careful. I can't remember for sure but I think Resistances don't just add directly. You may have to add their inverses. It's like parallel vs series resisances in an electrical circuit. I always have to check before I add them up. ie. 1/Rtot = 1/R1 + 1/R2 + 1/R3 etc...
Can anyone explain to me a little of the math of where the components to the G-2 equation come from? I understand we're calculating zone efficiencies here and I'm in the habit of considering efficiencies to be, generically, "output/input". Applying this interpretation of effiency in this case...
