What happens when air from the ceiling fans hits the ceiling in a room with a sloped ceiling? If the ceiling fan is centered in the room, it would be basically half way up the slope. So wouldn't all the air go directly up the slope from where the ceiling fan is mounted? What about the other half of the room? What happens when the room is large? Will the force, coming down the walls, still be enough to get this warm air to the floor, especially when the ceiling is two stories high? What happens when ceiling fans are in a room with a two story high ceiling, which is open to the second floor level of the home?
Office presentation rooms too do not desire light to reflect from the walls on to the projection screen or wall thus, here too, the back ceiling comes in handy. Commercial kitchens like the restaurants or hotels must have black color ceilings so that soot from charcoal ovens on grills that is deposited on the roof mainly does not alter the look and feel of the kitchen. A lighter colored roof for a kitchen can be disastrous since maintaining and cleaning can be a big issue. Blackened ceilings help solve this issue.
And if you happen to have a room with the two story ceiling where the room is open to the second level, and where you notice the upstairs is always hot while the lower level is cold during winter, try using your ceiling fans in the down direction. You will not believe the difference! The black ceiling is quite common in movie halls, theatres, the office presentation room or the commercial kitchen. Movie halls and theatres require light concentration from projectors only on the screen or from spotlights only on the stage. The rest of the hall must remain in pitch-black darkness, thus black ceilings are quite common in these places.
