description Temperature of water reflects cooling capacity stored in the stratified sensible chilled water storage tank. The temperature of the water is different on each slab inside the storage tank reflecting temperature distribution. This study focuses on the analysis of temperature distribution of chilled water storage tank of sensible stratified type using one dimensional flow heat conduction and convection model. Model was solved using explicit finite difference method. Two factors considered in this model were conduction across the transition of warm-cool water area and mixing effect during charging and discharging. Validation of the model used the operating data of chilled-water storage tank. The result revealed that temperature distribution generated from the model show similar profiles to that of the operating data. Using t statistical test, these values was accepted in a good agreement at confidence level 95%. Higher value of charging flow rate and lower water inlet temperature tend to produce higher cumulative cooling capacity. Different of aspect ratio results in slight difference on the temperature distribution and cumulative cooling capacity. Keywords : Temperature distribution, chilled-water storage tank
