after a little thought, i've decided to keep them open overnight. it will flush the hot air out, yes, but it will hopefully also turn the a/c off. i don't mind if the temperature in here goes up and down with the outside temperature, it's that frigid refrigerated air that i won't tolerate. i'd rather the outside cools it down down here on it's own, and keeps the coolants upstairs.

this is going to dramatically affect the tenant upstairs, but they drilled a hole in the floor so what else am i supposed to do...

what was happening this morning was that the coolants were sinking, as would be expected. if i do nothing, that will get worse and worse until the entire basement is a few degrees cooler than the upstairs.

i can only guess that what's happening upstairs right now is that the hot, humid air from the windows is rising up through the duct. and, the strength of this will depend on the heat outside.

it's cooling down a little this week....

....but it'll be warm again next week. a full week of 30 degree weather with the windows wide open like this could plausibly render his machine useless.

but, it's really sort of one or the other: i freeze or he sweats. and, i have entropy on my side.
