Abstract

Chilled Ceiling System is an alternative to conventional air conditioning system that provides thermal comfort to the occupant. Chilled ceiling is a device responsible for providing cooling effect by using Hydronic Radiant Cooling idea. Chilled ceiling panel is installed at the ceiling thus absorbed heat by natural convection and radiation. Hydronic Radiant Cooling is a system that used water as a heat medium transfer with air inside the conditioned space to achieve thermal comfort. In this study, to investigate appropriate chilled ceiling temperature and controlling relative humidity is a great challenge to make occupants comfortable. Experimental work will be conducted in the environment chamber using chilled ceiling with and without Aluminum sheet. The experimental method features an environmental chamber here the chilled ceiling panel model installed at the top of the chamber to develop a model of a typical room in Malaysia. The outcome parameters are room temperature, chilled ceiling temperature and relative humidity. As the result of the experiment, the appropriate temperature at the chilled ceiling to provide thermal comfort in the environmental chamber is from 5.3℃ to 6.3℃ where is cause the temperature in the environmental chamber from 22.9℃ to 23.8℃. This is due to temperature difference between chilled ceiling panel and the air in the environmental chamber. From the result, the appropriate temperature of the chilled ceiling can be determined to provide thermal comfort in the environmental chamber
