heat pump fan high or low?
Swinging into heating season here, I'm wondering if it's better
to run a heat pump's AHU blower at a higher or lower speed?
While lower is better for summer dehumidification, if we're only
interested in sensible heating then should we try to extract
as much as we can from the indoor coil, or take it easy and let
it run at a higher delta-T? What other factors would this
depend on? Assume a given unit's capacity matches well with
the entire available blower CFM range...
I tried searching for prior discussion but it's not clear what
I'd search *for* to quickly find such a topic.
