Experiment study of fire characteristics in full-scale bedrooms under different vents and sprinkler conditions

The risk of fire in residential buildings is relatively high, with a significant number of incidents and loss of life reported. This study aimed to examine fire scenarios in bedroom by conducting real scale experiments with different set-up of vents and using realistic fuel loads. Five full-scale compartment fire tests were conducted, and a sprinkler system was installed in one of the rooms. The experimental setup, fuel arrangement, and instrumentation are described, and the fire characteristics was analyzed based on visual observations and temperature data processing. The performance of the fire detectors and sprinklers in the tests are discussed. The influence of opening size on the peak temperature, heat release rate, and the constant coefficient of Kawagoe law are estimated and analyzed. Furthermore, a non-dimensional neutral plane height was found to have strong relationship with the constant coefficient of Kawagoe law.
