beenthere, that's awesome; a quick look at a psych chart makes
it make sense, except that the chart I usually use only goes
down to 20F. Still, clearly not a whole lot of grains to be
had in air that cold but they're obviously in there, and I
guess I need to think of the lower end of the dewpoint line
as the "hoarfrost line".
This morning it is, in fact, about 15F but the RH widget hung
outside says the humidity is higher than a few days ago, and the
outdoor unit is definitely collecting a bit more white than
when I began this thread. I think it's nominally about 1200
CFM out there but it's a variable-speed fan so who knows. I'm
sure I could sit here and try to do the math and run out to put
a pan underneath to see many pints of water dribble out on every
defrost cycle and how long between ... but who's got time.
I guess I can just hope that the thermal mass of the compressor
and the fairly fat blankie wrapped around it will let the unit
ride through most power outages, but I was originally thinking
days-long and what if I'm not home the whole time, etc. You'd
think one more thermistor stuck to the herm case to make sure
it's up to a safe temp before cranking it would be an easy bit
of insurance that manufacturers could put in, though..
