ASHRAE 62n Appendix G Efficiency Calculation
ASHRAE 62n Appendix G Efficiency Calculation
(OP)
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 (eq G-2) it seems to me the zone efficiency would be the ratio of zone OA fraction (output) to the system OA fraction (input). I'm having trouble, though, visualizing the mathematical terms in the equation w/ their physical equivalents. Am I interpreting this eqn wrong?
Thanks,

They also list the efficiency values for different diffuser/distrubution systems that the G-2 equation uses, as well as definitions of terms used in all 10 equations. Not sure this helps or not.
