Abstract

The purpose of this research was to develop a sensible cooling load calculation method for cooled ceiling (CC) systems. It was presented that cooling load of CC systems are different from those of the all-air (AA) systems by analyzing heat transfer mechanisms of CC panels and AA systems. A cooling load calculation method for CC systems was developed based on the room-heat-balance analysis model. The propose method can be used to estimate cooling loads of CC systems and those of ventilation systems which combined with the CC systems simultaneity. According to the calculation for a model room in Taiyuan, the peak load and average load of CC systems are higher than those of AA systems when the same design temperature of indoor air is adopted. It is revealed that an accurate cooling load calculation method should be used to estimate design cooling loads.
