Abstract

This paper presents an experimental study of radiant cooling for building air-conditioning in a tropical climate. To prevent condensation of moisture on the cooling panel, the temperature of chilled water supplied to the panel was limited to 25ฐC. This led to the limitations of heat extraction capacity at the panel and its application to only space with low thermal load and low metabolic rate activity of people in the space. A simple calculation of radiative and convective heat exchange between the interior room surfaces and the room air was applied to determine the rate of heat extraction by the panels. The calculation results can match well with the measurement results. Using a comfort index of predicted mean vote (PMV), the results from experiments show that thermal comfort could be achieved with the application of radiant cooling. ฉ (2013) Trans Tech Publications, Switzerland.
