Air doesn't care what I assume
In this long hot spell I've been trying to get proper performance from my air conditioner, with no luck until yesterday.
Top view of my little house. Living room on right, kitchen lower left, bedroom upper left. For many days I persistently set the AC to blow toward the bedroom. I ass-u-me-d that the flow would work like this:
But it didn't. Air didn't give a shit about my beliefs. Cool air never reached the bedroom. Terrible sleep, lots of sweat.
What actually happens is something like this:
Hot air gets sucked out of the kitchen, forming a hot blob near the kitchen door. Cool air doesn't make it past this 'mixing' operation.
Yesterday I finally violated ass-u-m-ption and set the airflow the opposite way. This seems ENTIRELY WRONG. Why should I want to cool the front door?
But it works beautifully. No hot blob, the entire living room stays cool, and enough of the coolness filters into the bedroom for comfortable sleep.
(Artistic sidenote: The house contains furniture, of course. I didn't show it here, but the furniture would seem to help my ass-u-m-ption. The path from AC to bedroom is open, and the path around the right side of the living room is cluttered. Nevertheless, the cluttered path works and the open path doesn't. It's all about the suction, I guess.)
