Abstract: The radiant ceiling cooling has the potential to provide better thermal comfort and air quality without draught sensation, save the architectural space and energy consumption, so it’s used as a promising air condition tip. The increasing radiant ceiling market demand requires a higher test for radiant ceiling cooling capacity. So in this study two radiant ceiling performance testing methods (DIN EN 14240 Standard and ANSI/ASHRAE 138) and two radiant ceiling cooling capacity calculation methods (ASHRAE Handbook and BS EN 1264 Standard) were introduced. Two testing methods and two calculation methods were compared respectively and a radiant ceiling cooling performance testing chamber in accordance with the testing standard EN 14240 was used to test the cooling performance of a metal radiant panel. The experimental cooling capacities were compared with the calculated results and the calculation error was analyzed.
