Most of that dust will go through the dry coil.
If it was wet, then more of it would stay on the coil.
Ok, learning time for a homeowner. At what OD temp is a HP defrost necessary??
Depends on outdoor humidity. And varies with the HP a bit.
Generally under 40°F. but once in a while it can happen above 40.
most homes in Bucks county have a plenum on top of the furnace which feeds a tee and goes in both directions to feed the conditioned space. You could easily install strip heat in each side of the tee, and interlock those so that on a call for defrost, these are enabled, and controlled off of discharge air temp. These could be staged for better control, or even done with an SCR if you want to get real fancy. Depends on which part of bucks you live in and how big your lawn is I suppose.....
I'm trusting the EAC's to keep the strip heaters clean
One problem with the strips before the evap coil is that then I can't use it for reheat.
The conventional view serves to protect us from the painful job of thinking.
No, but pre heat can still increase humidity control.
i seem to remeber a lot of your posts about reheat (i assume for dehumidification) or to cut down on system cycling

it cost zero to operate heat pipe reheat!
i used to be involved with the installation of heat pipes in miami fl.
