Abstract |
Cooling ceilings consist of a network of cooling ducts suspended from the ceiling and covered with ceiling panels. The air velocities account for much of the comfort in an air conditioned room. Air velocities were measured in model rooms where the cooling ducts covered 90% of the ceiling. The heaters were either arranged in one corner or evenly distributed throughout the room. Lacquered and unlacquered ceiling panels used to cover the cooling ducts were tested. Results are presented in diagrams and a table. It is concluded that comfortable air velocities below 15cm/s are produced in rooms cooled from the ceiling at the level occupied by people. |
