碩士 === 國立交通大學 === 工學院產業安全與防災學程 === 106 === Taiwan shopping malls into the international development of various types of goods, the internal fire load high. In the event of a fire, it is more difficult to escape than the general building in fire rescue and evacuation. In large shopping malls, automatic sprinkler equipment in the fire protection plays an important role. In the world have a successful case of firefighting, it is the world's fire authorities and the insurance sector recognized as a more reliable firefighting equipment. Taiwan's automatic sprinkler system specification source mainly from the Japanese norms, in the design, whether it is the design concept, process, calculation formula and parameters with the United States or mainland China is different. Taiwan regulations, not only in the design of a simplified situation, and does not meet the principles of engineering calculations. Designers in the planning stage of the provisions of the rules and regulations of the design, the lack of design rules, resulting in practice often face as a legitimate but unreasonable problem. Today, Europe and the United States in the design of computer software to take more hydraulic calculations, through the engineering development of computer simulation software, and Taiwan's design methods and processes are different. This study mainly takes the shopping mall model as an example, uses the software of KYPIPE computer to calculate and compares the result of hand calculation, and then uses the actual design case of American shopping malls and high-rise residential buildings to simulate with hydraulic calculation software. In the calculation method, there are mainly pipe size calculation and hydraulic calculation method. In the results of this study, the calculation results of the American pipe size method are quite different from hydraulic calculation or Taiwan law, Calculated according to the law of the sprinkler density. However, in the hydraulic calculation method, the United States is similar to China. However, the Chinese standard system adopts the Shervieve formula (Ф • A • ЩевеЛев), which is different from the United States using the Haven-Williams formula. In the calculation results of this study, Pump energy requirements than the United States. The result of hand calculations in Taiwan is equivalent to the minimum demand for simulation of hydraulic calculation software. In addition, the simulation of computer software to simulate the pump, the basic requirements of hydraulic calculations compared to manual design of the pump low. This study is then compared with tree, mesh and ring. In the same pump set, the distance between the head and the diameter of the pipe, regardless of the amount of water or radiation pressure and other water supply are the best mesh; ring followed; tree the weakest, resulting in increased water density. If you maintain the same sprinkler head spacing and water density, mesh and ring can be used smaller size of the pump. In the actual design example, the original US shopping malls to Taiwan's regulatory approach to design, failed to meet the designer's request, but to increase the ability to pump. The high-rise residential building in the spread of 15 sprinklers at the same time, the end failed to meet the regulatory requirements. This study suggests that the future may refer to the design method of the United States, as well as the use of more network or ring pipeline configuration mode to provide better water performance, and more use of computer hydraulic simulation to simulate various conditions of water release to improve system reliability, and international Connect.
