I'm trying to understand the fan performance chart of a Mitsubishi mini split unit. The manufacturer submittal sheet shows the airflow (lo/med/hi) as 423, 529, and 635 CFM, and they then list the ESP at 0.02 - 0.06 - 0.14 - 0.20 "WG.
They provide four fan performance charts at .02, .06, .14, and .20.
Here is a link: http://www.google.com/url?q=http://w...TGQhT-E-lIuMDA
The rated point shows at 635 in all four graphs for the High setting. If ESP is increasing, shouldn't the CFMs be dropping for the high setting?
When I look at the CFMs for the .06 graph for the low setting, I believe it is showing ~370 CFM. But, when I look at the .14 and .20 graphs, it looks like the low setting is above the line labeled Limit. Does this mean the fan won't move any air at those pressures at the low setting?
