The purpose of this experiment is to grasp the efficiency of the heat prevention of the drencher that is used as the compartmentalization in a building. We prepared the two types of specimen that has the different size of opening. The both position of the drencher head and the amount of discharged water are treated as the parameters. And the specimen is heated under the condition of water curtain. We observed the following tendencies ; 1) If the both heat temperature and the drencher's dram are fixed, the measured temperature of non-heated wall side is fixed. 2) The efficiency of heat radiation prevention becomes higher depending on the amount of discharged water increasing.
