Space cooling using metal ceiling panels is analysed experimentally and theoretically. Measurements are performed in a 2.0×2.5×3 m 3 test chamber with a 1.80×2.16 m 2 cooling panel located on the undersurface of the chamber ceiling. Both experimental and theoretical analyses show that the dynamic response of the panel system in conjunction with the thermal comfort conditions is satisfactory for the climate of Greece. Under certain conditions the condensed water vapour may raise dripping problems, for which solutions are proposed. Energy savings exceeding 12.5% may be obtained from the increase in acceptable indoor temperature, but further savings are possible from the higher temperatures of cooling water, which improve the efficiency of solar-driven absorption chillers.
