The purpose of this study is the establishment of the Computational Fluid Dynamics (CFD) field model, taking into consideration water discharge equipments, such as sprinkler equipments (SP). The fire control effect of the water discharge equipment was investigated using a CFD field model. The computational results were compared with a full-scale compartment fire experiment in which the water discharge equipment was installed. When the water discharge equipment was not used, the computational results of the temperature distribution in the compartment were in agreement with the experimental results. When the water discharge equipment was used, the numerical simulation could not predict the experimental value with sufficient accuracy. One of the causes for decrease in prediction accuracy is the condensation heat transfer mechanism generated on the wet wall. In this study, the prediction accuracy of the numerical simulation could improve by taking into consideration the condensation heat transfer.
