6)Fire hydrant system design indoor and outdoor
Outdoor fire hydrant water is 30L / s, set three outdoor low voltage ground fire hydrant.
Fire hydrant water was 43.51L / s, set five fire water riser, use the fire hydrant 65mm diameter, 19mm gun nozzle diameter of 65mm with rubber hose length of 20m. Fire hydrant protection radius of 28.1 m, the most negative point hydrant hydrant pool with the lowest level of hydrostatic pressure 0.794MPa. Head of 104.84m, flow Q = 43.51L / s. Optional ISW125-315A model pumps, lift 110m, flow 50L / s, speed 2900r/min, Efficiency 70%, power 75kw, the choice of the model pump groups, one with a prepared. Fire water tank effective volume taken 18m3. Effective volume of fire water taken 246m3..
7)Automatic sprinkler system design
Automatic sprinkler system used wet sprinkler system. Design objects are dangerous hazard class Class I level. Design parameters water density 6 L / (min • m2), the role of area 160m2. Design uses a rectangular nozzle arrangement, each nozzle actual protection area 12.5m2, the role of the most negative point of the area several nozzles 18. Calculate the most unfavorable point of the nozzle flow 72L/min, system design flow 28.8L / s, the total loss of the pipeline 0.36168MPa, the most negative point of the working pressure 0.081MPa, hydrostatic pressure 0.783MPa. Optional spray pump 2 (1 with a prepared), specifications XBD12.5/40-125L-315, Q = 40L / S, H = 125m, speed 2900r/min, power 90KW. Fire water volume 103.68m3, fire water tank volume of 17.28m3. Fire pump adapter 2.
8)Automatic fire alarm system design
The hotel is a high-level design objects object of protection, centralized alarm system, and set the fire control room. Smoke detector design selection, pided into two layers detection unit, detector protection area A = 60m2, protection radius R = 5.8m. Calculated the number of detectors arranged in a layer 55, floor 55, three 24, four 18, five to nineteen layers 23, basement 127. Detector installation spacing a = 10m, b = 6m.
Key words: high-rise building; fire protection system design; hydrant system; automatic fire alarm system; configuration of fire extinguisher
