- Abstract:
- This paper investigated the fire control and fire extinguishing performance of an automatic sprinkler system in a class E warehouse, and reasonably determined the setting requirements of the automatic sprinkler system. Based on the preliminary established fire test model, three groups of automatic sprinkler system full-size fire extinguishing tests were carried out under different clearance heights and storage modes respectively, and the heat release rate (HRR) was analyzed by fire dynamics principle when the first sprinkler was started. When the roof height was less than 9 m, 9 L/(min·m2) water spraying intensity was capable of controlling the stacking fire with a height less than 3.5 m. However, the water spraying intensity of 32 L/(min·m2) could not control the rack fire with a height less than 7.5 m. When the first sprinkler was started, the HRRs were 2.4 MW and 6.4 MW, respectively. When the roof height was less than 6 m, 25 L/(min·m2) spraying intensity could effectively control the rack fire with a height less than 4.5 m, and the HRR was 3.5 MW when the first sprinkler was started.
