Abstract

Chilled ceiling is the main part in Hydronic Radiant Cooling (HRC) system which offers appropriate cool for occupants by combining of thermal radiation and natural convection effect. The effect of varying chilled ceiling positions are tested at height 0.47m, 0.41m and 0.35m in environmental chamber for achieving thermal comfort condition.The limitations associated with conventional air-conditioning systems such as high energy consumption, poor ventilation and do not environmentally friendly are opened the door for find an alternative solution. Two purposes of this study are to investigate the possibility of accepting the chilled ceiling system as an alternative system towards the conventional air-conditioning system in Malaysia by adopting the proper HRC system design and to investigate room temperature by identifying the oppropriate height of the chilled ceiling panel for achieving thermal comfort temperature. Design and fabrication new model with implementing experimental work are the main approach to achieve standing objectives. An environmental chamber with the dimension of 0.7 m (L) × 0.5 m (W) × 0.5m (H) is used to conduct the experimental work. The most important parameters measured in this chamber are room temperature inside the chamber and relative humidity. The best height for chilled ceiling panel can be optimized at 0.35m for providing thermal comfort which is equal to 2.1m at the actual room with temperature of 24.6°C and relative humidity of 56.9%. It is expected that the chilled ceiling system can be applied in Malaysia associated with integrating independent system for dry air. Therefore, thermal comfort temperature can be achieved with energy reduction when the position of chilled ceiling panel is varied at optimum position. The current project is ready for contribution in saving energy and environment.
