Dogie is correct that the air escapes from the bottom and top of the unit. see this photo.
Dogie is wrong that it is not cooler at least in my case. It is cooler this way with
1 unit in a 12 by 12 by 7.5 very well insulated room.
It is 1 or 2 f cooler with the window shut.
It is 4 or 5 f cooler with the window open and outside air was 15 or 16 f this morning
a lot of air comes out of the bottom of the unit. IN this photo now the bottom Is a wall of aluminum heat sink facing us
I am going to make a solid bottom over the weekend will post on Monday.
look close I have a few heatsinks on the unit.
