An innovative air-conditioning concept of a chilled ceiling combined with a floor-level ventilation system was developed in Europe and North America. Full-scale testing results in office spaces equipped with such systems showed that occupants can readily achieve thermal comfort. Currently, chilled ceiling system has not been widely used in office spaces in tropical climates which are characterized by a much higher cooling load, lower clothe value and high relative humidity. The objective of this project is to use CFD and scale model testing techniques to determine the ability of chilled ceiling to satisfy the thermal comfort and indoor air quality criteria in tropical climates.
