I am wrapping up the insulation and walls on my meat locker, its 11' 6" x 9' 6" with a 7'2" ceiling height. I'm trying to figure out a good location for the wall unit, I'm not sure if I should put it on the same wall as the door facing the rear of the room, or put it on the west wall opposite end of the door facing across the room. My door is on the east wall.
