Abstract
AbstractThe purpose of this study was to investigate whether the PMV index can evaluate the thermal comfort in ceiling radiant panel systems. In a previous experimental investigation using an office equipped with radiant cooling panel, it was found that the indoor relative humidity and indoor air velocity kept at 61.5 % and 0.01 m/s, respectively, could help to reduce condensation on the chilled surface and increase thermal comfort. The value of PMV and predicted percentage of dissatisfied (PPD) were calculated with the data measured and recorded in the test room, and they would be validated with the result of 85 thermal comfort questionnaires. By comparing the conclusion, it was concluded that there were some residuals when using the PMV calculation formula to calculate the value of PMV in ceiling radiant cooling panel system compared with the realistic, and a correction coefficient was needed in the PMV’ equation.KeywordsCeiling radiant cooling panelsThermal comfortPMV-PPDApplication
