Use of cold radiant ceilings for building climatization.

Summary

The performances of air-cooled radiant ceilings in terms of energy saving and thermal comfort were investigated. A theoretical procedure was developed in order to evaluate the cooling load reduction of air conditioning systems which is achievable, at equal comfort level, when cold ceilings are in use. A parametric analysis was performed, with respect to the room shape factor, the glazing percentage, the air velocity, the air change rate and the climatic conditions. Results show that a considerable reduction of the cooling load can be achieved and that cold ceilings are particularly suitable for open-space and curtain-wall buildings.
