Progress on Chilled Ceiling Systems

The superiority of chilled ceiling includes providing better thermal comfort, lower energy consumption andoperation cost. It is considered a kind of new air conditioning technique due to comfortable and energy saving. This paperreviewed the studies of chilled ceiling.The thermal comfort of chilled ceiling systems different from traditional airconditioning systems were evaluated in terms of work condition parameter and thermal environment index. The savingenergy advantage were analyzed according to fan energy consumption, radiation heat transfer characteristic andrefrigerating medium substitutes. Concerning the research technique of chilled ceiling, several simulation models,application software and experiment methods were assessed. The paper proposed that domestic researchers should paymore attention to design method, material substitutes and manufacturing technique after improving simulation andexperiment measure.
